Downloads
Mandatory Downloads:
- Custom Shaders Patch version 0.1.78 or newer
- SOL (free) or its premium successor Pure to facilitate the day/night transition
(be sure to check version compatibility between your CSP and SOL/Pure versions) - Real Penalty (manual installation required: necessary for Driver Swap & Penalty handling)
- WSC Legends 1960s Mod v1.2
- AC Legends GTC 60s Mod v1.2
- TVR Griffith 200 by pctm_00 (because the GTC60 TVR references its kn5 models)
- Inivisible-TV-Car
- Le Mans 1967 v1.0.5 by racinjoe013 + THR 2025 Layout
Optional Recommended Downloads:
- Substanding Extended
- Blinker Sound App (to hear your blinker)
- Dashboard Indicators (in case your car does not come with have a dash light for the blinker)
- THR Skinpack for WSC Legends: https://thr.vacbot.cz/skinpacks/THR_WSC_skinpack.7z and for AC Legends https://thr.vacbot.cz/skinpacks/THR_ACL_skinpack.7z
- If you want to add your own custom skin to the skinpack, please follow this guide
- Installation of Skinpack ideally on the day of the race: to install the custom skins of your fellow competitors in this event, please paste the URL above into Content Manager and click "Install" in the dropdown Burger Menu of Content Manager
Configuration Requirements
- Confirm that your CSP & Sol/Pure installations, including controller script selection in Weather FX, are compatible with each other. You can verify that through the readme of your Sol / Pure versions before you install and activate them. If you combine incompatible versions, you will encounter severe glitches regarding brightness levels during day/night transitions and at night
- PPFilter & sun ray settings that allow for sufficient vision by day, night and sunrise/sunset on a single setting
CSP Car Instruments Settings
- Set "Headlights will break in crashes" to OFF: failing to obey this ruined the race of 4 teams in 2022.
- Set "Use high beams mode by default" to ON
Controls Patch Settings
You are expected to configure the following yellow-highlighted inputs in SETTINGS -> CONTROLS -> PATCH to an input that you can use while driving.
Mandatory:
- Hazard lights: all cars are equipped with hazard lights. If you crashed and bent your suspension in a way that enables you to limp back to the pits safely as long as you reduce your speed, you need to turn on the hazard lights to warn the drivers behind you that you are in trouble!
- High/low beam toggle: please enable yourself to toggle between high & low beam headlights because this has a significant impact on how far ahead you can see while driving at night. In practice, CSP should already have set the checkbox under "Settings / CSP / Car Instruments: Input Options: Use high beams mode by default" to YES by default. It's enough to have this somewhere on your keyboard because you won't toggle this more than once, and ideally never.
Strongly wished, but we recognize that not everyone has enough buttons or keys in reach:
- Turn Signals left & right: all cars are equipped with turn signals that work on all cars until at least their first Level-of-Detail-simplified models that AC loads to improve performance when different cars are further away from you. Please enable yourself to use these turn signals to signal on which side of the road you continue while you are getting lapped by someone else.
Hint: the Blinker Sound App, already linked above, lets you hear if your blinker is on.
Real Penalty Setup
- Real Penalty is linked in the mandatory downloads at the top and necessary for you to install and activate, because it handles the Driver Swaps and checks if it is installed on your client: if you don't have it (as well as CSP v0.1.78 or newer), you will get kicked by the server.
- To install Real Penalty successfully, you must install it manually (NOT via Content Manager!)
- After installing and activating Real Penalty in Content Manager (Settings / Assetto Corsa / Python Apps -> hit the checkmark on Real Penalty), you can launch an Assetto Corsa session and open the In Game App "Real Penalty Settings" to order the elements on your GUI.
Relative Positions Display Apps
Although the Driver Swap works in AC, almost all of the in-game timing apps get confused by the driver swap. By yourself as a driver, you can only find out your overall position only using the Kunos default "F9" leaderboard pictured below, which you activate by cycling through the F9 button in an AC session.
This app only updates data once a lap when you cross the start/finish line. It is also quite hard to keep track of while driving, so be sure to have a co-driver available to monitor the Live Timing and keep you posted on who of the drivers around you is actually fighting for position with you and who is just lapping traffic.
However, realtime-style apps are still a valuable asset that you should use here, but you need to know what they can and can't do in this endurance setting! We recommend to use "Substanding Extended", which you find linked in the the Downloads near the top of this website.
This will work: identification who are the cars around you during the lap
This won't work: after your first driver swap until the end of the race, the displayed positions will be wrong!
There are several further examples of suitable similar apps, such as the following two and more:
- Realtime (default Kunos app that tells you the delta to cars ahead & behind in seconds, but not the make and class; position display gets wrong as soon as you perform a driver swap)
- Vr AO Standing (a standings app that was tailored to VirtualRacing.org's customized Assetto Corsa endurance server environment and therefore only delivers all features if you are connected to that: be aware that when you use it on a THR server, the position display gets wrong as soon as you perform a driver swap but it can still be used to see the physical distances to nearby cars in seconds and meters correctly)
Performance Optimization
With more than 50 cars connected to the server, you have to brace for an unusually high performance requirement for your hardware, and particularly the CPU. The number of cars that we will have on the grid considerably exceed the number of cars that we typically see in THR events. Unless you have a top-of-the-line CPU in your PC, you should be prepared to dial back some of your Video Settings and CSP configurations to achieve a better performance.
As a hint, a few effective parameters for settings in Content Manager that help to reduce the load on your Processor (even though they are video settings, they affect your CPU indirectly as well) are listed below:
- CSP Settings: Extra FX -> off
(Extra FX is a secondary rendering pass to add more visual effects: performance-heavy!) - CSP Settings: Graphic Adjustments: enabling AMD FidelityFX Super Resolution (with a slightly reduced quality setting, such as 77%) can considerably improve your framerate, even if you have an NVIDIA graphics card
- CSP Settings: there are various other modules that are not directly necessary, which you could consider to disable as well to yield better performance - but always keep on Weather FX, Car Instruments, Graphic Adjustments, and Lighting FX
- Assetto Corsa Settings: Video: in a performance-boosted Video Settings preset, you could, for example, reduce the resolutions of shadows, reflections and mirrors, and set the World Details to a lower level
To validate your settings, please test them offline as follows:
If your configuration can handle a full AI grid (you + 53 AI cars from the WSC60 set) at Le Mans 1967 without frequent "CPU occupancy >99%" warnings (excluding when major AI pileups occur) and while you yield a good framerate (and no slow-motion!), you will have enough headroom for peace of mind that your system can handle everything that this race can throw at it!
If you get a slow-motion experience and these "CPU occupancy >99%" warnings in this test scenario, you need to optimize your settings further. If you cannot resolve these issues by yourself, please request help in the #technical-stuff channel on the THR discord.
In case your PC proves to be too weak to handle this load reliably despite all optimization efforts, you should reconsider participating, because this scenario is guaranteed to make your car teleport all over the track due to delayed physics calculations and delayed location update feedback from your PC to the server!
Track Rendering Troubleshooting
As a safety precaution, we carried over this section from the 2024 edition of the race that was driven with an older baseline version of the track. We hope that these issues are rectified by that, but we kept this section in the event website for easy reference if you encounter any issues. You can skip this section if the track gets rendered correctly throughout the entire lap on your PC, and without any crashes.
If Assetto Corsa crashes when you exit Tertre Rouge and Content Manager gives you the notification screen "Game crashed. GPU failed; might be overclocked too much, or overheated", you need to go to your CSP / General Patch Settings and disable the option marked pink in the screenshot below:
Next troubleshooting topic:
Some combinations of settings in the Extra FX module of Custom Shaders Patch can cause momentary rendering failures of the track on your screen at two spots that would look like this on your screen:
- in the approach to Indianapolis
- after Tertre Rouge at the start of Ligne Droite des Hunaudières
Here are two ways to solve that:

Car Descriptions
We are using a selection of cars from the WSC Legends 1960s and the AC Legends GTC 60s Mod. That selected range of cars is assigned to two classes for this event. We tailored the class assignment list to Le Mans as a compromise between the greatest possible variety of cars and the chance to experience exciting battles in all three classes.
Prototype 7.0 Class
The top class of cars we offer to choose in this event is called the Prototype 7.0 class (P7.0). It covers Prototype race cars with an engine displacement of up to 7000 cc and top speeds between 315 and 340 km/h.
Chaparral 2F
The Chaparrals, built between 1963 and 1970, stand among the most iconic sports-racing cars in history, alongside legends like the Ford GT40, Ferrari 330 P4, and Porsche 917. Created by Jim Hall, these cars revolutionized motor racing with groundbreaking aerodynamic innovations, including wings and ground effects. Hall’s approach to using downforce to improve traction forever changed the sport.
The Chaparral 2E Can-Am car from 1966 exemplified this ingenuity. Not only did it feature mid-mounted radiators. The most important innovation was a tall and movable wing, actuated by the 3rd pedal to adjust aerodynamic balance and drag during braking and acceleration instead of actuating a clutch, as this car was fitted with an automatic transmission. Such a wing had only been seen once before in high-profile circuit racing: on the privately-entered Porsche 550 Spyder of Michael May, during practice of the 1956 Nürburgring 1000 km. May had beaten the Porsche factory team's cars by 4 seconds and his wing was then promptly outlawed by the officials under pressure from the Porsche factory team that really didn't want to be beaten by a young engineering student. The 2E featured tall rear wings, mid-mounted radiators, and an innovative third pedal that adjusted aerodynamic balance during braking and acceleration. These advancements allowed the cars to achieve superior traction and handling without compromising weight.
In 1967, the closed-cockpit Chaparral 2F demonstrated the potential of these aerodynamic aids on the global scene, proving that carefully designed wings could significantly enhance cornering speeds. Hall’s philosophy was simple but revolutionary: make aerodynamic forces work for the car, not against it. This led to innovations such as rear-mounted wings directly connected to the suspension, venturi-shaped noses for improved front-end stability, and adjustable aerodynamic systems controlled by the driver.
The 2F coupe, built for the 1967 World Championship of Makes, combined these innovations with a powerful 7-liter V8 engine, lightweight glassfiber construction, and center-lock wheels for quicker pit stops. Despite its potential, the car faced reliability issues, particularly with its H-Pattern-controlled 3-speed automatic transmission. Even so, Hall fondly regarded the 2F as a faster and better-handling car than competitors like the Ford Mark IV. Hall's pioneering spirit and persistence to fight back against rulemakers and find new opportunities for engineering innovation led to a huge leap forward in racing technology. After the SCCA banned his fan-assisted Chaparral 2J from Can-Am at the end of the 1970 season, he left the racing scene for years. The year after his return to CART in 1978, his last race car design hit the track in the shape of the 2K that went on to win the 1980 CART Championship and the prestigious Indy 500. Hall's Chaparral team continued to compete in CART successfully until 1996.
This car is truthfully fitted with a moveable aerodynamic device that would nowadays be called a Drag Reduction System (DRS), and you will need to use that as often as you can in this event. The 7 liter V8 burns through the 160 liter tank within roughly 335 kilometers. While the top speed is only 318 km/h, the grip and braking performance with the help of the wing are unparalleled.
Ferrari 330P4 Berlinetta
The Dino 246 SP, introduced in 1961, marked Ferrari’s first step into mid-engine sports cars. This innovation set the stage for the legendary P-series, starting with the V12-powered 250P in 1963, which secured Ferrari’s first mid-engine Le Mans victory. Despite Ferrari’s dominance in both prototype and GT racing, Henry Ford launched a fierce challenge after his failed attempt to buy Ferrari, leading to the creation of the Ford GT40.
In 1964, Ferrari’s 330P, with a more powerful 4-liter engine, outpaced the underdeveloped Ford GT40 at Le Mans, achieving a 1-2-3 finish. However, the battle intensified as Ford escalated its efforts, introducing a 7-liter GT40. Ferrari responded with the P2, but reliability issues hindered both teams, with Ferrari salvaging its reputation through a NART-entered 250 LM that broke down just after reaching the checkered flag.
By 1966, Ferrari unveiled the P3, featuring fiberglass doors, a relocated clutch, and Lucas Fuel Injection, boosting performance and top speed. While it achieved early victories at Monza and Spa, factory labor issues compromised Ferrari’s Le Mans preparations. Ford capitalized on this, achieving a historic 1-2-3 finish at Le Mans.
Determined to rebound, Ferrari introduced the P4 in 1967, with the refined 4-liter engine now featuring a 3-valve head and fuel injection building on technology from Ferrari's F1 program. Testing at Daytona paid off, as Ferrari dominated the Daytona 24 Hours, claiming the victory with the 330P3/4 Spyder, followed by a new 330P4 Berlinetta, and a 412P which was the carbureted 2-valve privateer version of the P4. Several 412P were rebuilt from existing P3 chassis, as it had been done on the winning P3/4. However, at Le Mans, Ford’s GT40 Mk IV, with its 7-liter V8 and innovative monocoque design, edged out Ferrari on sheer horsepower and one of them ended up on top of the podium. The two surviving 330P4 salvaged 2nd and 3rd place ahead of the only other Ford that saw the checkered flag, while the other 8 Ford GT40s and both GT40-based Mirage M1s retired. The other two factory P4s were less fortunate: the Daytona-winning 330P3/4 Spyder Chassis 0846, having been repaired after its recent crash at the Targa Florio, caught fire after a right-rear puncture at high speed and was later scrapped according to Ferrari, while the P4 of Günther Klass and Peter Sutcliffe was taken out by an engine failure after 296 laps. Despite these setbacks, Ferrari clinched the World Sportscar Championship for the 12th title in 14 years.
The 330P4 Berlinetta is a good race car overall, with a top speed of 318 km/h. However, it is hamstrung by Ferrari's inexplicable design decision to fit only 114 Liters of fuel capacity, rather than the 140 Liters that the rulebook would have allowed them with this engine displacement. You'll visit the pits every 280 km, but your individual pit stops are shorter than those of the faster cars.
Ford GT40 Mk II
After two years of steady progress despite some setbacks, Ford and Shelby American continued their GT40 endurance racing campaign, introducing a revised Mk II for the 1966 season after the first version of it had proven to be the primary opposition to the Ferrari 330P2. The 1966 iteration was designed to challenge Ferrari’s radical 330P3 with significant upgrades, particularly around its aerodynamics, engine, and reliability.
At the 1965 Le Mans, Ford had debuted the GT40 Mk II fitted with a massive 427 CID (7.0 Liter) engine from its Galaxie NASCAR program and an extended nose. While these cars showcased impressive top speeds, hitting 210 mph on the Mulsanne Straight and out-qualifying Ferrari by nearly ten seconds, they suffered from reliability issues, with both retiring due to transmission failures on their Kar Kraft KKL-108 gearboxes: hasty preparation had led to one gearbox being equipped with a gear that was intended for scrap, and the other one had ended up with a dirty bearing surface. Despite these setbacks, the 427 GT40 demonstrated its potential, prompting Ford to refine the design for the following season.
The Mk II featured key improvements. Shelby American worked with Ford’s Engine and Foundry Division to reduce the engine’s weight, shedding 50 lbs with aluminum heads and other refinements. Although the power output dropped to 485 bhp, the engine was now paired with a dry-sump lubrication system and a robust transmission to handle its torque better, addressing the reliability issues from 1965. Shelby also revised suspension points and reinforced the chassis selectively to balance strength and weight. Brake performance was a critical focus: the discs were already the largest possible size for the GT40's wheels and already at the limit in the lighter and slower GT40 Mk I, and the brake ducts already cooled them too strongly. Phil Remington, Shelby’s chief engineer, developed a quick-change disc brake system to address the wear issues caused by the car's increased speed and weight. This innovation allowed teams to replace worn discs efficiently during long races.
The Mk II’s upgrades paid off spectacularly at the 1966 24 Hours of Le Mans. With Henry Ford II in attendance, the GT40 Mk II dominated the event and secured a historic 1-2-3 finish that marked the first overall Le Mans victory for an American manufacturer.
The enormous 159 Liter fuel tank enables the GT40 Mk. II to cover up to 360 km on one tank at Le Mans. Watch out on the brakes! You'll need to stomp on them at 400-420 meters if you want to make it through Virage de Mulsanne alive. This car has the longest braking distances of the entire field, matched only by the drum-braked Mercedes 300 SL(R) and the GT40 Mk. IV.
Ford GT40 Mk IV
Perhaps the most significant post-war American race car ever produced was Ford's GT40 Mk. IV GT40, and it is nothing short of a racing legend. It was the ultimate development of the GT40 platform, and it took the fight straight to Ferrari, dominating a field that included the Ferrari 330P4 and the Chaparral 2F, as well as its predecessors, the GT40 Mk I and the 3rd iteration of the Mk. II that was dubbed Mk IIB.
As history would reveal, the Mk IV would only be campaigned in two races, at the 1967 12 Hours of Sebring, where Mario Andretti and Bruce McLaren piloted a Mk IV to victory, and at the 1967 24 Hours of Le Mans, where Dan Gurney and A.J. Foyt outperformed all to the checkered flag and won the Index of Performance. That victory is the only all-American outright win of an American-built chassis, engine, team, and drivers at the fabled Le Mans 24-hour endurance race.
The 7 litre Ford engine had the durability to go 24 hours, providing the rpm range could be controlled. Ford issued a firm edict to all drivers that 6200 rpm was the limit. No exceptions, even though the engine had a safe limit of 7400 rpm for short-term use. To this end, each car's tach was accurately calibrated and a calibration chart taped in the driver's side door jamb.
Due to the Mk IVs unparalleled performance, the FIA quickly relegated the Mk IV to racing extinction by outlawing any prototype car that had larger than three-liter motors.
With the same 159 Liter fuel tank as on its predecessor, the GT40 Mk. IV can cover up to 335 km between pit stops, but its performance is aided by lower weight and improved aerodynamics. With a top speed of 338 km/h, the Mk. IV is the undisputed King of the Hunaudières, but watch out for the braking points, because your brake distances are just as long as on the Mk. II. Enormous accidents are just one mistake away at these speeds.
Prototype 2.0 Class
The second class of cars that you can choose for this event consists of Prototypes with an engine displacement of up to 2000 cc. With a power output of 220 to 260 hp, the P2.0 cars are expected to deliver an extremely intense fight throughout the entire distance of the race, reaching speeds of 270 to 280 km/h without slipstream.
Alfa Romeo 33 Periscopica
Having been established in 1961, Carlo Chiti's Autodelta became Alfa Romeo's official competition department in 1963. With the TZ model, built in 100 units, they had delivered a successful 1.6 Liter GT race car. Parallel to deriving the sleeker TZ2 version from that, by late 1964, they had also begun developing the Tipo 33 to replace the TZ racers in factory-backed races altogether. Unlike its GT predecessors, the Tipo 33 was designed for the 2.0 Liter prototype class to challenge Porsche's ongoing dominance. With minimal carryover from previous models, the project required over two years of development before its racing debut.
The Tipo 33 featured Alfa Romeo's second-ever mid-engine chassis, built around an innovative H-shaped design using three large-diameter riveted aluminum tubes. This lightweight yet rigid structure housed rubber fuel tanks within the side members and was reinforced with magnesium cross-members. The suspension used a conventional setup with double wishbones at the front, while the rear comprised of lower wishbones, top links and twin trailing-arms. Ventilated disc brakes were fitted all around, with the rear brakes mounted inboard to reduce unsprung weight.
The heart of the Tipo 33 was a 2.0-liter V8 engine developed by Chiti, drawing on his experience with the ATS V8. Made from lightweight alloys, the engine featured twin-cam heads, dual spark plugs per cylinder, and an advanced fuel injection system. Despite its compact size, the high-revving V8 produced an impressive 254 hp at 10000 rpm, rivaling Porsche’s flat-8 engines. Unlike the subsequent Tipo 33 Stradale and Tipo 33/2 that were fitted with flat-plane crankshafts, the engine in the Periscopica featured a crossplane crankshaft. This engine was complimented by a custom six-speed gearbox, an almost unheard-of feature in race cars at a time when even most Formula 1 cars only had five gears.
The Tipo 33 debuted in 1967 with a Spider body and a distinctive periscopic engine intake, earning the nickname "Periscopica." It won its first outing at the Fléron hill climb in Belgium but struggled with reliability in international events, possibly compounded by the vibrations resulting from running a cross-plane crankshaft at 10,000 rpm. Additional wins only came in hill climbs and smaller races, such as Vallelunga, but the car's fragility limited its broader success. The best result in the 1967 World Sportscar Championship was a 5th place in the Nürburgring 1000 km, a lap behind the winning trio of Porsche 910/6 that ran in the same class as the Alfa Romeo. Autodelta continued refining the Tipo 33, focusing on reliability and aerodynamics. A one-off Spider with a revised design was tested at Mugello, signaling ongoing efforts to enhance the car’s performance. Despite suffering from these issues, the Tipo 33 Periscopica laid the groundwork for Alfa Romeo's subsequent successes in prototype racing, starting with the 33/2 Coupe the next year at Daytona.
In the 2025 THR 6 Heures du Mans, the Alfa Romeo 33 Periscopica stays true to its legacy of 1967 as an underdog. Although its acceleration is fantastic thanks to a powerful V8 engine and the 6-speed gearbox, the open roof reduces its top speed to 265 km/h and the projected fuel range is only roughly 310 km. You won't win in this car, but you'll finish in style.
Chevron B8 FVA
Derek Bennett, a self-taught mechanic and racer from Bolton, England, became renowned for his skill in repairing and modifying cars, often restoring wrecks to like-new condition. Alongside his work in Bolton, North England, Bennett showcased his racing talent by building custom cars dubbed "Derek Bennett Specials," which gained a loyal following. In the 1960s, Bennett formalized his creations under the name "Chevron," inspired by a symbol in the Highway Code.
Chevron’s early success came with the B1 and B2 Clubman racers, prompting demand for a GT model to rival the Lotus Elan. Instead of adapting an existing design, Bennett envisioned a mid-engined car, leading to the construction of the B3 and B4. The B3, powered by a Ford 1.6L twin-cam engine, and the B4, equipped with a 2.0L BMW engine, debuted in 1966. Both cars featured spaceframe chassis and lightweight aluminum bodies. The B3 secured a victory at Oulton Park on its debut, marking the start of Chevron's winning streak.
In 1967, Chevron introduced the B6, a production version of the B4 that was now fitted with fiberglass bodies: six with BMW M10 engines, and one with a Ford twin-cam powerplant. The B6 quickly proved its prowess and started racking up wins. Most notably, though, the one-off Chevron B5 with the same BRM engine that was also fitted to the Matra M630 scored an international Group 6 victory in the Anerly Trophy at the BUA International Trophy Meeting in Crystal Palace with Brian Redman behind the wheel, beating even the Lola T70 Mk 3 GT of Mike de'Udy to mark Chevron's first victory on the international stage.
To compete in the 2.0 Liter class of Group 4 Sportscar races, Chevron needed to homologate the B6. Bennett boldly set out to produce the required 50 examples, resulting in the B8 in 1968. Although initial production fell short, the FIA approved the car after inspecting the available supplies and factoring in the B6 production numbers. Ultimately, 44 B8s were built, featuring a variety of engines. The B8 achieved numerous victories, including a class win at the Daytona 24 Hours in 1969. While most Chevron B8s were powered by the BMW M10, a number of them were also fitted with the 1.6 Liter Cosworth FVA Formula 2 engine, such as Barrie Smith's chassis BO8-DBE68 from 1969, which is pictured above.
The B8 eventually evolved once again to the one-off B12, a 3.0L Repco-powered evolution of the B8, which won its debut race at Silverstone in 1968. In 1969, the B8 was replaced by the B16 which led Chevron to its heyday during the 1970s. Chevron was on its way to Formula 1 when Derek Bennett tragically passed away after a hang-gliding accident in 1978, and his company went bankrupt just two years later.
Fitted with an endurance-oriented and therefore more conservative tune of Cosworth's mighty FVA, the 2.0 Liter Prototype class-winning car of the 2024 THR 6 Heures du Mans is back for the 2025 edition and remains featherweight of the 2 Liter Prototype class at 553 kg, albeit with a tricky handling with a fine line between understeer and overrotation. Revving the engine to just short of the moon will yield up to 222 hp that now allow the B8 FVA to hit up to 277 km/h, while offering a fuel range of up to 375 Kilometers.
Dino 206S Berlinetta
The Dino 206 S is a sports prototype produced by Ferrari in 1966–1967 under the Dino marque. Ferrari intended to produce at least fifty examples for homologation by the CSI in the Sport 2.0 L Group 4 category. As only 18 were made, the car had to compete in the Prototype 2.0-litre class instead. In spite of this handicap, the Dino 206 S took many class wins. The 206 S was the last of the Dino sports racing cars and simultaneously the most produced.
The first racing result was a fifth place in the 1966 12 Hours of Sebring, driven by Lorenzo Bandini and Ludovico Scarfiotti. Three cars entered the 1966 Targa Florio the same year under Ferrari SEFAC team. Jean Guichet and Giancarlo Baghetti finished the race in second place also with a class win. Other cars finished fourteenth and not at all. 1000 km Spa netted sixth and first in the prototype class for Richard Attwood and Jean Guichet. At the 1000 km Nürburgring, Scarfiotti and Bandini took 2nd overall, trailing the winning 5.4-litre Chaparral 2D by only 90 seconds, and thereby won the Prototype 2.0 class to deliver a crushing defeat for Porsche in their home event, where the best 906 E finished a lap behind while the new 906/8 was forced to retire from 3rd place after 36 laps when the gearbox failed. Ferrari even scored a 1-2 in class here, as the sister car of Pedro Rodríguez and Richie Ginther's car followed in 3rd place overall. The third Dino 206S, entered by Maranello Concessionaires, had retired after 27 laps. Rodriguez scored a class win at the Nassau Trophy. At the Brands Hatch GP circuit, Mike Parkes scored sixth overall and first in class. The Dino 206S won VI Coppa Citta di Enna. Also in 1966, the Swiss Mountain Grand Prix was won by Ludovico Scarfiotti. One important race of the 1966 season was not mentioned here: the 24 Hours of Le Mans, where everything went wrong. Three Ferrari 206S were entered by NART, Maranello Concessionaires, and Scuderia San Marco, and all of them retired within 14 laps.
In 1967, the Dino 206S did not show up at Le Mans anymore. However, Swedish driver Gustaf Dieden finished Swedish National Falkenberg and GP Swerige in fifth and ninth respectively. The Dino 206S Spyder returned to the Nürburgring 1000 km in 1967 with Scuderia Filipinetti, while Ferrari SEFAC was completely absent to focus on preparing for the 24 Hours of Le Mans that took place just two weeks later. Scuderia Filipinetti was out of luck, though: the 206S of Herbert Müller and Jean Guichet burned down during practice due to a carburetor fire. Ferdinando "Codones" Latteri and Pietro Lo Piccolo scored many overall and class wins in hillclimbs and regional championships events in Italy between 1967 and 1969.
With a top speed of 276 km/h and 100 liters of fuel, the high-revving V6 will enable this 580 kg pocket Ferrari with razor-sharp handling to cover up to 335 km between fuel stops.
Matra M630 BRM
By the mid-1960s, French victories at the 24 Hours of Le Mans were a distant memory, with Italian, British, and German teams dominating the legendary endurance race. That changed when aerospace company Matra, new to automotive racing, announced its ambitious goal to win the 1969 Formula 1 World Championship and the 1970 Le Mans 24 Hours with an entirely French car. Enthusiasm soared, fueled by a pivotal rule change for 1968 that limited prototype engines to 3 liters - the same displacement as in Formula 1 - allowing Matra to develop a dual-purpose engine.
Matra’s early sports cars, the M620 and M630, were built with spaceframe chassis and fiberglass bodies, using BRM and Ford engines. The M630, introduced in 1967, featured a 1.9-liter BRM V8 producing 245 hp at 9,000 RPM. Despite its advanced design, the M630 struggled with multiple setbacks in its first season. In the Le Mans Test of 1967, Jean-Pierre Jaussaud complained about the aerodynamic instability of the rear. Seeking a second opinion, the Matra team sent out the driver of the M620 in the M630 as well. It would become the last time Jacques Pierre Robert "Roby" Weber left the pit lane. He lost control on the Ligne droite des Hunaudières and barrel-rolled into a nearby garden, already dying upon impact before the car caught fire. Weber's accident nearly ended Matra's racing program. Jean-Luc Lagardère wanted to stop everything with immediate effect. Fortunately, one of the engineers was able to convince him that Weber's loss would have been for nothing if they gave up now. They had to continue, they had come too far. At the 24 Hours of Le Mans of 1967, a burst oil pipe and a suspension failure took both M630s out of contention. Matra continued to refine its cars, learning from setbacks. Later in the season, the M630 BRM its only victory in the Criterium de Vitesse at Magny-Cours, as well as 9th overall in the Paris 1000 Kilometers.
Towards the end of 1967, the M630 chassis #02 was fitted with the 4.7 Liter V8 engine of the Ford GT40 and won 8 of the 10 national races it participated in (while retiring from the other two) before until it was retired in late summer 1968. In the meantime, chassis #03 and the newly-built chassis #04 had been equipped with the new 3-liter V12 engine from Matra's Formula 1 program. The modified car debuted at Spa and performed well at Le Mans, where the Pescarolo/Servoz-Gavin duo initially raced strongly but retired due to a puncture, accident, and electrical fire.
When Simca joined Matra as a sponsor in 1969, the car was renamed MS630 and scored a respectable fifth-place finish at Le Mans with Jean Guichet and Nino Vaccarella. Although the M630 did not bring Matra major victories, it laid the foundation for future success. The experience gained helped Matra develop the MS650 and refine its approach, paving the way for its eventual dominance in mid-1970s prototype racing and achieving its vision of projecting French excellence on the global stage.
At 648 kg, the Matra M630 BRM is the 2nd heaviest car in the Prototype 2.0 Liter class of this year's edition of the THR 6 Heures du Mans. Thanks to its F1-derived V8 engine, however, it's also one of the fastest, with a top speed of 281 km/h and good high-speed cornering capabilities. Can the Matra M630 BRM overcome its unfortunate past and dethrone the Chevron B8 FVA in this year's THR 6 Heures du Mans? Time to find out! The projected fuel range is approximately 320 kilometers, as revving to 10000 rpm to extract 260 hp from a 2.0 Liter V8 takes its toll on efficiency.
Porsche 904/8 Coupé
The Porsche 904 is the predecessor of the Porsche 906. During 1964 and 1965, the Porsche factory team raced a total of three 904 Coupés with a 2.0 Liter version of the Type 771 flat-8 engine that was tuned to approximately 240 hp in the Coupé and increased its weight to 690 kg as opposed to a typical 904 GTS's 655 kg in race trim. The 904/8 Coupé usually stood in the shadow of its more successful GT cousin (Carrera GTS with a flat-4 engine) and the 904/6 Coupé that joined the 904/8 in the 2.0 Liter Prototype class for 1965 and already had chassis numbers that started with "906" in anticipation of becoming the production 906, which didn't happen. The best results that the 904/8 Coupé achieved in international endurance races were a pair of overall 3rd places in the 1965 editions of the Nürburgring 1000 km and Paris 1000 km, combined with the class win in the 2.0 Liter Prototype class on both occasions.
At Le Mans, however, the 904/8 Coupé never lasted beyond roughly the halfway point of the event before it succumbed to engine or clutch failures. The car already comes with accurate skins for each of the events that the three 904/8 Coupé chassis 904-008, 904-009 and 904-082 participated in or were brought to as a backup car during competition from 1964 to 1966. The racing legacy of the 904/8 ended at the 1966 Nürburgring 1000 km race, where 904-009 was retrofitted to the 904 GTS's flat-4 engine and became the pioneer of live onboard TV coverage in motorsport by delivering the racing action straight from the cockpit of the racing journalists Paul Frère and Rainer Günzler to the living rooms of Germany's ZDF TV audience.
As the Type 771 engine in Assetto Corsa is expected to be more durable than the real thing, the class-leading top speed of 283 km/h and fuel capacity (110 Liters) will allow this little heavyweight to regain some of the time it loses through curves and take the fight back to its younger, more agile, and more efficient competitors for up to 390 Kilometers nonstop. This car is the anachronist of the P2.0 class in the 2025 THR 6 Heures du Mans. Brought in as an underdog from an older generation of two liter Prototypes, this car is unlikely to take the class win but offers a long-distance performance similar to that of the thirstier Alfa Romeo that spends more time in the pits.
Porsche 910/6
The Porsche 910 was designed specifically for international endurance racing. Derived from the Porsche 906, the 910 led Porsche's assault on the 1967 World Sportscar Championship: both on the 2.0 Liter Prototype class with the 910/6, and on the 3.0 Liter Prototype class with the 910/8 that was fitted with the enlarged 2.2 Liter version of the Type 771 Flat-8 found in the 2.0 Liter 904/8. This enlarged 2.2L version had first been raced unsuccessfully in the 906/8 Coupé.
The 910 differed from the original 906 with its use of 13-inch wheels and tires like in Formula One , and it was shorter and lighter, which made it good competition for the more powerful GT40 and Ferrari prototypes. The 910 also featured a single large central nut rather than the 5 lugs in the 904 and 906’s, which made the racecar not street suitable, but it definitely saved time at pitstops. It also featured a more rounded design everywhere and the roof panel was removable. Because of this targa roof, the cool-looking gullwing doors of the 906 had to go.
The 910 was quicker than 906 thanks to its Formula 1 tyres and better aerodynamic balance, offering much higher cornering speeds, but the brakes had to be smaller because of the 13″ wheels. Quicker car with smaller brakes – it is a very good evidence of the mentality of the era, motorsport was for the brave ones.
The factory only raced the 910 for about a year during which it was very successful. The 910/6’s main class rival was the Ferrari Dino 206S, which was quickly beaten. In the 1000 km Nürburgring of 1967, a fleet of 6 factory cars were entered in an effort by Porsche to score the first overall win in Porsche’s home event: three 910/6 Coupés and three 910/8 Coupés. The 8-cylinder model disappointed, as two of the three 8-cylinder engines broke down. The slower but more reliable 910/6 Coupés, meanwhile, gave Porsche their first outright win in a third major event of the World Sportscar Championship for Porsche, with the surviving 910/8 in 4th place overall completing the Porsche's overall 1-2-3-4 lockout behind the 910/6 trio.
The sunset was already on the horizon, though: the new Porsche 907 Langheck was already entered in Le Mans that year with the proven flat-six powerplant and finished 5th overall in front of a 910 and two 906s. After the 907 entirely replaced the 910 in the factory team, the 910/6 went on to enjoy an extended second career in privateer hands that lasted well into the 1970s.
Thanks to the fantastic fuel efficiency of the fuel-injected factory team version of the Type 901 flat-six with 220 hp that revs lower than the competition, not only will you reach up to 277 km/h in this car, but you also get to enjoy a range of up to 375 km between fuel stops.
GT class
The third class of cars that you can choose for this event consists of Gran Turismo (GT) sportscars with an engine displacement of up to 5500 cc. With a power output of 300 to 390 hp to reach top speeds between 258 and 288 km/h, they will deliver plenty of strategic action between fast thirsty cars and slower cars with significantly better fuel economy and lower refueling needs.
Chevrolet Corvette 1967
The second-generation Corvette sold from 1963 to 1967 and came to be known as the Sting Ray. This particular car was born from a handful of experimental and prototype machines that designers/engineers Zora Arkus-Duntov and Bill Mitchell had worked on toward the end of the C1 production run. For Zora, the car had yet to reach its full performance potential in the first generation. There was one big problem: the Automotive Manufacturers Association's ban on allowing production cars to compete in racing. This didn't stop the duo, though, as they and other GM employees dedicated after-hours time to designing and building early Corvette concept racecars.
The Corvette C2 Smallblock L79 327ci engine, available in the Corvette from 1965 to 1968, also turned pedestrian Chevy II and Chevelle Malibu SS sedans into true musclecars. The L79’s power output came thanks to a Holley four-barrel carburetor, a dual plane aluminum intake manifold, 2.02-inch intake valves and 1.60-inch exhaust valves, a forged steel crankshaft, and an 11.0:1 compression ratio.
This 390 hp V8 propels this 1168 kg heavyweight through the wind and up to a top speed of 276 km/h. Combined with the enormous 160 Liter fuel tank, the Corvette is a good allrounder that can cover up to 335 km between stints. You'll spend more time refueling than many of your competitors, though, as you will need a 3rd pit stop.
Jaguar E-Type Le Mans
An E-Type prototype had been raced at Le Mans in 1960, long prior to its introduction. When the production version arrived on the scene, the new E-Type did win its first time out at the Oulton Park GT Trophy Race, with Graham Hill behind the wheel. But the decade’s most luscious GT tourer was no racer.
At Le Mans in 1962, the Cunningham team entered a factory-prepared car. Briggs Cunningham and Roy Salvadori averaged 108.87 mph for 24 hours. That speed was just 5 mph slower than the D-Type’s best average ever, and was good enough for fourth place, behind three Ferraris. In major races Jaguar’s venerable long-stroke twin-cam six just couldn’t produce the horses to counter the new three-liter cars from Maranello. For its stalwart followers, the company did subsequently build a dozen aluminum-bodied lightweight E-Types, which performed admirably in club events throughout the world. Despite such efforts, a major racing offensive was not in Jaguar’s plans.
Fitted with a 140 Liter fuel tank and a 4-speed transmission, the E-Type will comfortably cruise down the Hunaudières at 281 km/h. Its good fuel efficiency allows for a range of up to 442 km between fuel stops, making this car a great candidate for crews of 3 drivers - because if you get it right and make the tyres last, the two mandatory long stops are all you'll need to cover 6 hours.
Mercedes-Benz 300 SL(R)
The idea of a toned-down Grand Prix car tailored to affluent performance enthusiasts in the booming post-war American market was suggested by Max Hoffman. Mercedes accepted the gamble and the new 300 SL-300 for its 3.0 litre engine displacement and SL for Sport Leicht (Sport Light) was introduced at the 1954 New York Auto Show rather than the Frankfurt or Geneva gatherings company models made their usual debuts. Immediately successful and today iconic, the 300 SL stood alone with its distinctive doors, first-ever production fuel-injection, and world's fastest top speed. The original coupé was available from March 1955 to 1957, the roadster from 1957 to 1963.
To keep up with the competition in a more modern field, the W 198 road car was lightened compared to the rather heavy production version, and upgraded with the powertrain of the famous 300 SLR (W 196 S) "Uhlenhaut" Coupé. This is a 3.0 liter inline-8 engine with a desmodromic valvetrain and the direct fuel injection developed during WW2 by Karl-Heinz Göschel for the Daimler-Benz DB603 and DB605 aircraft engines. While the direct fuel injetion and good aerodynamics give the Gullwing the class-leading fuel efficiency and the superb 288 km/h top speed at once, this car also comes with a handicap.
Both the 300 SL (W 198) and the 300 SLR (W 196 S) were drum-braked. Although you get the enormous drum brakes of the 300 SLR with a strong initial bite, they fade severely in long braking zones, forcing you to brake for Virage de Mulsanne no later than at the 400 meter board. You will also encounter strong fading at Indianapolis and Arnage, so you will need to adjust your braking style to the fading of your overheating drum brakes. This takes a toll on your laptimes as well.
With a range of up to 470 km between pit stops, however, the highly efficient Mercedes-Benz is the undisputed range king in this field. Just like the Jaguar, it lends itself particularly well to crews of 3 drivers, as the two mandatory pit stops are all it takes to cover 6 hours at Le Mans in this car if they can make the tyres last long enough.
Shelby Cobra 289 Competition
Combining the power of Ford’s short-stroke V8 with the nibleness of AC’s sporting chassis, the Cobra was the first largely successful English-American hybrid. The whole project was motivated by legendary driver Carol Shelby, who refined and raced the car with funds from Ford. In what some have called a desperate move, AC Cars accepted a deal to modify their Ace chassis to accept Ford’s V8 engine. They shipped bare chassis to Shelby American where they were initially fitted Ford’s 260 cu in. engine. The V8 worked well within the spacious engine bay, so much so, Shelby moved to the 289 unit in 1964. Since development was relatively simple, the Cobra started winning races from its onset. It had a tremendously good power to weight ratio that bettered with both the 289 and later 427 engines.
The Shelby Cobra 289 Competition models were team-specification roadsters built by Shelby, which raced as factory-sponsored entries in the early-mid-1960s. As a factory-specification competition car the 289 Competition Cobra came directly from the Shelby factory with a bonnet scoop, a chrome roll bar, 6½-inch Halibrand front wheels (8½-inch at the rear), flared wings, Koni shocks, front and rear sway bars, competition brakes all around, quick-jack points, side pipes, dual long-range fuel tanks, a Monza snap-open fuel cap, a racing seat, a Sun tachometer, a fuel-pressure gauge, a differential cooler, an engine oil cooler, an electric Stewart-Warner fuel pump, and an aluminium Harrison header tank. At its heart of the roadster was a full race-specification 289 V8 that had 4 Weber carburetors and a 12:1 compression ratio.
The major drawback of the open Cobra is found in its horrendous aerodynamics. Although the Cobra's brakes, traction and acceleration are fantastic, it will succumb to the wind at just 258 km/h. The large 140 Liter tank makes the thirst of the V8 somewhat bearable, offering a range of about 310 km between fuel stops. With these ingredients, it's an enthusiast's choice.
Shelby Mustang GT350R
The 1965-67 Shelby GT350 was not built for comfort or ease of driving. There were 34 "GT350R" built in series as a turn-key race car, specifically for competition use under SCCA rules, and the model was the B-Production champion for three straight years. Many changes were done to the body, including the fittament of a distinctive front apron in fiberglass. Flares were added to the fenders to accommodate 15×7 inch wheels. Furthermore the side and rear windows were were replaced by Plexiglas with aluminum frames. Underneath, Shelby changed the pickup points on the suspension, added traction bars for the rear suspension and installed a new differential. Inside, a new instrument cluster was added with a tachometer and oil pressure gauge. A large 4-point roll cage was installed to provide a little bit of passive safety for the driver.
With more power than the engine versions fitted to the Cobra and TVR here to reach 269 km/h comes even more thirst. Nevertheless, the fuel tank that was generously expanded from 128 to 140 Liters allows the Mustang to cover about 280 km between fuel stops. Like the Cobra, the Mustang is more of an enthusiast's choice here.
TVR Griffith 200
Jack Griffith had a long-term passion for sports cars and racing, perhaps fueled by his 1947 purchase of a new MG TC. At one point a Jaguar franchise was added to Griffith’s dealership lineup, and when Carroll Shelby announced the Cobra in 1962, White-Griffith Ford was one of the car’s early retailers. Jack even campaigned a factory-prepared 289 Cobra in SCCA competition, but soon realized a career as a racing driver was not in the cards.
Through the SCCA, Griffith met Dick Monnich, a distributor for the low-volume British sports car brand TVR. In the fiberglass-bodied TVR Grantura III, Griffith saw potential, but not enough power. Borrowing a page from Carroll Shelby’s own playbook, Griffith and Monnich shoehorned a Ford 289 V8 into the TVR, with the help of a dealership mechanic and some design work from a young New Jersey engineer named Mark Donohue, who also served as a (brave) test driver.
Jack Griffith came up with the idea for the car in 1964, and secured rights to market the cars in the US. Griffith ran a car repair workshop in the US for patrons such as Gerry Sagerman and Mark Donohue who had both driven a TVR Grantura at Sebring International Raceway in 1962. The concept for the Griffith Series 200 originated during a dinner with Carroll Shelby, where Griffith declared he could build a car that could outperform an AC Cobra.
Griffith’s words to Carroll Shelby came true in 1965, where Tom Lynch in a Griffith 200 beat Shelby’s factory racing Cobras with Ken Miles and Dave Mcdonald at the wheel for about eight laps until a C Production car ended up in the gravel and covered the Goleta race track with rocks, being in first place the Griffith 200 hit the rocks and blew the left rear tire resulting in a DNF!
Unfortunately, the Griffiths – which were known to be a rather scary drive for the uninitiated – also became known for overheating issues, undercharging electrical systems, failing rear axles and leaking gas tanks. This on top of the fact that Griffith bodies were mounted to the chassis with strips of fiberglass.
With the same powerplant as the Cobra and an even shorter wheelbase but slightly better aerodynamics that offer a top speed of 262 km/h, the TVR is a very fast car in the right hands. However, the thirst of the 289 engine taken from the Cobra Competition is only quenched by a 109 Liter tank that forces the TVR into the pits every 240 km. While that means your fuel stops are shorter, it also means that you'll need more of them. The only way to drive the TVR, therefore, is hard. Are you up to that challenge?

Track Description
The 1967 Circuit de la Sarthe in Le Mans hardly needs an introduction to endurance racing enthusiasts all over the world. As the world center of endurance racing, it has hosted countless triumphs and tragedies throughout the past 100 years. True to the era from which this event's car roster comes from, this is still the highest-speed variant of the track, without the Ford Chicanes, and without the Porsche Curves that were built in the 1970s to bypass the treacherously fast and blind Maison Blanche chicane.
Based on the stunning Le Grand Circuit by woochoo & Virtua_LM that was initially ported to Assetto Corsa by Terra21, racinjoe013 improved it further by providing a more accurate look and feel of the environment. For the 2025 edition, we have updated to racinjoe013's most recent baseline version 1.0.5 and added a renewed and deliberately renamed version of last year's THR custom layout with 54 diagonal starting grid spots directly on the pit wall and 54 straightly-alined pitboxes.
Yes, you heard that right, it's a Le Mans start again: everyone gets lined up diagonally along the Pit Lane's wall for a standing start. If you want, you can run across your room when the lights go green before jumping into your simulator to get going, but adding that level of immersion for yourself might cost you a couple of dozen positions. It could, however, save you from catching a pit speeding penalty from crashing into the pit lane from a start collision - and yes, that really happened in 2022.
Most importantly for this year, you have to re-learn how to navigate Maison Blanche!
In addition to updating to racinjoe013's most recent baseline version of Le Mans 1967 and giving it the starting grid & pit lane layout we need, Pitman has overhauled the walls at Maison Blanche to make the experience more realistic for us.
- The Maison Blanche apex wall was moved closer to the track, making it similarly close to the inside white line as reality in 1967 (Note: the virtual track has far too much asphalt to the left of the white line - in reality about 30-40 cm - and the virtual Maison Blanche layout is generally a bit faster than the real track was in period)
- The Maison Blanche apex wall is also collideable now (instead of a hole that lets you fall of the track)
- The end of the fence on the left before Maison Blanche was reprofiled to deflect you away from the beginning of the moved Maison Blanche apex wall
- The Maison Blanche entrance's outside wall on the right side is also collideable now, and so is the short wall between the two stacks of haybales on the right side: like the old apex wall, both were previously a hole that you fell into if you drove into them slowly enough
Bonus: we have also updated the track's Extension Config to fix the Haybales by injecting newly-made proper txNormals and txMaps/txDetail textures for the Haybale material. The haybales now respond to environment lighting far more realistically. Speaking of realism, they now also don't like when your exhaust flames get too close to them. The fire brigade will extinguish them after a bit, but they'll be charred by then.

Special Rules for the Event
Basic Rules at THR
- The basic THR racing rules apply to the Endurance race as well
- THR Race Control will review incident protests that are submitted by drivers through the "Protest an Incident" ticket of the THR Ticket System until 29th January 2025, at 23:59 CET.
- Instead of Point Penalties, Time Penalties will be used
- The race result stays unofficial until THR Race Control confirms it
Pit Lane Rules
Most importantly, do not back up more than two car lengths in pit lane. In 2022, a driver's actions in a mistaken attempt to back out of the entire pit lane caused a fatal 300 km/h collision. We do not want to see anyone doing something similar this time!
Standard Pit Stops
To make a regular pit stop (no Longstop, no Driver Swap), it's all business as usual:
- You drive into the pit lane: be sure to be below 80 km/h the moment your car enters the pit lane. Unlike when you serve a penalty, during "pit stops" only your pit lane entry speed gets tracked by Real Penalty, so as soon as you have arrived on the pit lane surface, you can speed up again - but please be cautious in the pits and don't cause any accidents here!
- you stop in the red box in front of your pit crew to perform whichever pit strategy you have set in your pit menu
- Normal pit stops (fuel/tires/repairs while the driver stays on the server) are not subject to the Long Stop time restrictions. Ignore the timer of Real Penalty if you don't perform a "Long Stop". Details on those are described in the next chapter.
Long Stops with(out) Driver Swap
Until the end of the race, every car has to serve a total of two mandatory "Long Stops" that are governed by a timer in the Real Penalty App.
The "Long Stop" is a feature built into Real Penalty to assist endurance racing. The Long Stop offers a standardized time window to level the ground between solo drivers and drivers who share a car and perform driver swaps when they follow the guideline correctly, and crucially without providing a time disadvantage to drivers with slower loading times for joining an Assetto Corsa session. Think of it as a minimum pit stop duration that your car only needs to adhere to on two occasions!
During a Long Stop here, a car has to spend 180 seconds between the pit entrance and the pit exit.
The reason for that time window is that this provides a comfortably wide-enough timeline for Driver A to drive into the pit lane, stop the car in the swap zone (outside of their pit box) & disconnect from the server in the swap zone before Driver B connects to the server to take over the car from Driver A. Driver B then has to keep track of the Real Penalty Long Stop Timer on their screen to identify when they will be allowed to exit the pit lane. Each participating car has to comply with the instructions below to perform a Long Stop successfully.
Some teams with only 2 drivers may consider performing a Long Stop without disconnecting from the server, and that is possible. A Long Stop doesn't technically force you to disconnect if you race together on the same Simulator Rig, or if you are a team of only 2 drivers where you only want to perform 1 real driver swap. To clear a Long Stop, your car simply needs to spend an uninterrupted 180 seconds between pit entrance and pit exit, after entering the pits while driving. You may not perform a Driver Swap directly after Teleporting to the Pits, because that would render your car unable to reconnect!
You only need to adhere to this during two pit stops in the race, unless you make more driver swaps!
If you want to swap drivers more often than twice, you technically can do that but it's a huge disadvantage. The moment you initiate a Driver Swap where one driver disconnects from the server and another driver of the same car connects to the server, your car's pit stop forcibly becomes a Long Stop in which you must comply with the 180 second Long Stop timer in Real Penalty. That would happen even after you would have already completed your two mandatory Long Stops, every additional unnecessary driver swap will cost you almost an entire lap.
Note:
- An individual driver's stint time is not limited.
- Driver swaps magically heal your car:
- your damage gets reset
- you can load your setup & set your fuel tank to full before you jump into the cockpit during a driver swap
How to Swap Drivers during a Long Stop:
- Drive into the PIT LANE and do not exceed the speed limit of 80 km/h! You must reduce the speed to a max of 85 km/h before you enter the pitlane. (If you enter the pits too fast, your team will be penalized).
- When you enter the pit lane, RED indicator will show "Keep driving to swap": you need to continue driving through the pit lane until this text on screen changes to "Stop to swap".
- As soon "Stop to swap" indicator appears, stop the car at any place in the pitlane but don't stop directly in front of your pit crew! During a driver swap, the connecting driver can load the setup with fuel and tires.
- As soon the car is fully stopped, the "Stop to swap" text changes to "Swap possible" will appear. You can now press ESC and quit Assetto Corsa.
- As soon as your Assetto Corsa client has closed, it's time for one of your co-drivers to connect to the race server. It is only possible to connect to the server after another driver has disconnected from the server. There is no need to rush the change because there is an equal countdown of 180 seconds during the two mandatory Long Stops, and this time window is plenty enough to complete a driver swap, even if your computer has slower loading times in Assetto Corsa.
- After joining the server, load your setup and click drive as usual. Don't forget to load the setup you would like to use during your stint, because otherwise, the default setup with significantly less fuel will be loaded!
- You must ensure that the countdown "Pitlane time" reaches 0 before you exit the pit lane. This countdown is the remaining minimum time of your Long Stop in order to make your Long Stop valid. The 180 second countdown starts when your car enters the pit lane, and the timer gets stopped prematurely by exiting the surface of the pit lane before the time is up. If you leave the pit lane before the 180 seconds have concluded, you will be penalized by Real Penalty with a time penalty of 30 seconds plus the remainder of the countdown. If you leave the pits way too early, your Long Stop might not even get counted as a Long Stop at all.
- Once you see "GO" instead of the Pitlane Time, it means that your Long Stop is completed and you are ready to leave the pit lane. You are able to roll away from your pit box before the timer reaches 0 but DO NOT leave the pit lane before the timer gets to 0.
- Drive out of the defined pit exit as described in the Pit Exit Code of Conduct: accelerate as hard as you can while staying on the inside line of the track throughout turn 1 until after the Dunlop Bridge.
You can checkout a Real Penalty Demonstration video for the Driver Swap here:
Assetto Corsa - Real Penalty - Demo "Driver Swap"
(the video shows more Real Penalty features but we only use pit speed limits & driver swap)
Note:
- Driver Swaps mess up your in-game Live Timing & Blue Flags, giving you two challenges:
- Broken in-game Live Timing:
After completing your car's first driver swap, your in-game live timing apps will not display your position correctly anymore. You can only use them to identify who drives the cars that are around you, but the positions next to the other drivers's names will always be wrong. - Broken in-game Blue Flags:
After completing your first driver swap, your in-game blue flags will display nonsense for the rest of the race. - Solution for both:
- Your co-driver needs to watch the live timing at http://5.75.183.156:8772/live-timing?server=4 to keep you informed about which nearby cars you are fighting with for position, and which cars are either lapping you or about to get lapped by you.
- The only in-game App that can show you correct positions is the default F9 leaderboard app that you can bring up by pressing the F9 key. However, it only updates data once per lap (start/finish line) to tell you your position and the interval to the cars positioned ahead and behind you. These slow updates and the poor user interface make this app hard to follow and interpret correctly while driving. It shouldn't be more than a backup plan for you.
- Broken in-game Live Timing:
- No Stint Duration Limits: it's entirely up to you how much time which driver spends behind the wheel
- Every Driver Swap magically heals your car:
- your car's damage gets reset
- you can load your preferred setup before you jump into the cockpit
Pit Speed Limit
While it is not historically accurate to enforce a speed limit in the pit lane, it helps to avoid massive crashes that can happen next to an open pit lane if drivers enter the pit lane at very high speeds and lose control while trying to get their cars stopped in their pit box after applying the brakes too late.
However, we have disabled the automatic 80 km/h pit limiter on our server to avoid losing control through a game-forced application of your brakes. Consequently, you have to ensure by yourself that you will not exceed the pit speed limit even after you entered the pit lane!
The Real Penalty pit limit is set to 85 km/h. You must be slower than that to avoid a speeding penalty.
- When you only perform a pit stop, you can already accelerate after the pit entrance again
- When you are in pit lane to serve a penalty, you must remain under 80 km/h for the entire duration of the pit lane (valid for both Stop & Go and for Drive Through Penalty)
Also, all drivers must comply with the pit lane entry/exit instructions described in the infographic below:
Pit Exit Code of Conduct
The pit exit at Le Mans 1967 is very dangerous, so it is of the greatest importance that all drivers know and respect the Pit Exit Code of Conduct that is outlined in this section and the video below!
- Parallel pit exit below the tower only, no diagonal pit exit!
Mind the speed limit until you have cleared the pit exit (you will see it in Real Penalty, not enabled below). If you were in the pits for one of your two Long Stops, make sure your Long Stop Timer reaches 0 before you drive through the exit of the pit lane. - As soon as you are out of the pit lane:
Accelerate as hard as possible and stay on the inside line of Courbe Dunlop until after the Dunlop Bridge. DO NOT LIFT THE THROTTLE UNTIL AFTER DUNLOP BRIDGE! Failing to obey this would greatly increase the chances of a major accident here. - If you are on a flying lap and see somebody else leaving the pits:
Take a sufficiently wide line into Courbe Dunlop that leaves enough room to the car that leaves the pits! The example below with an AI-driven Ford GT40 was mere inches away from disaster.
Penalties
Penalty Types:
- Automated Penalty displayed in Real Penalty App GUI: Pit Lane Speeding:
- Level 1: 85 to 100 km/h: Drive Through Penalty
- Level 2: 100 to x km/h: Stop and Go 10 Seconds
- Automated Penalty displayed in Real Penalty App GUI: Premature Pit Exit after Driver Swap:
If a driver sets off before the minimum time during a Driver Swap, they will be given a penalty equal to the number of seconds left in the countdown plus 10 seconds. The penalty will be applied after the race. - Manual Penalty: Post-race decisions by Race Control:
Participants can submit formal protests against incidents that occurred during the race. These will be reviewed and decided upon by Race Control after the race. If Race Control issues a penalty, that will typically be a time penalty that is added to a participant's race result.
Note that the first two penalty types are shown on screen by the Real Penalty App and must be served very quickly. If Real Penalty gives you a penalty, you MUST comply with it. That particularly includes scenarios where you crashed into the pit lane as an innocent victim of an accident that somebody else caused. It's tough if you get a speeding penalty for crashing into the pit lane, but there is nothing that we can do about it.
How to serve a Drive Through Penalty (within 3 laps):
- Maintain a speed of less than 80 km/h while driving through the entire pit lane from entrance to exit
- Slow down to less than 80 km/h before the pit entrance
- Exit the pit lane at less than 80 km/h, and only at the end of the pit lane
How to serve a Stop & Go Penalty (within 3 laps)
- Stop in the pitlane, but not in the red box of your pit crew!
Simply come to a stop anywhere else within the boundaries of the pit lane. - Hold your brakes and wait for the penalty countdown to finish.
- As soon as your penalty countdown is over, drive to the pit exit and rejoin the race immediately.
- Attention 1: Do not perform a pit stop while you visit the pit lane to serve a penalty!
- Attention 2: Penalties cannot be served in the red box of your pit crew, even if you disabled the refueling & tire changes through the pit menu!
- Consequences if you fail to obey that:
If you stop in your car's pit box, Real Penalty will register a pit stop, and that will reset your penalty as soon as you exit the pit lane so you'll have to serve it again.
- When to serve your penalties
- You generally have 3 laps to serve a penalty. If you miss that time window, your race is over because the server will disqualify your car from the race.
- Special Case 1 - the handed-over Penalty:
If Driver A received a penalty but did not serve it before handing over the car to Driver B, the penalty time gets converted into seconds and will be added to the Driver Swap time of 180 seconds. - Special Case 2 - the last-minute penalty:
If you cant serve the penalty before the end of the race, the penalty seconds (+30 seconds) will be added to the result after the race.

Limping and Teleporting back to pits
There are four ways to get back to the pits during a race, but as long as your car is intact, there is only one: driving into the pits like everyone else and performing your scheduled pit stops, which may not be shortened by porting the car back to the garage.
However, certain major accidents like the one below can damage your car so severely that racing to the pits at full speed in a car with severely impaired control would be irresponsible for safety reasons.
In compliance with THR Basic Rule #10 "Teleporting back to pits", this chapter describes in greater detail how you can approach these scenarios. Although your choice of action is of a highly individual nature depending on your accident, the exact effect that it has on your car's steerability, and your individual ability as a driver to handle that situation, you must act responsibly above all else, and this chapter is a guideline that explains a suitable course of action.
Option 1: How to safely limp a damaged car to the pits for repairs
- Consider this before you try to limp your car back to the pits:
- If your car is severely damaged, and you are already so close to the end of the lap that you want to limp it to the pits because it costs you less time than teleporting, the first thing you need to do is a damage assessment: Are all of your wheels still on the car and can you control your damaged car well enough to get to the pit lane without posing an unjustifiable hazard to other participants?
- Only if you can control the trajectory of your car reliably at a speed of at least 60 km/h, you are allowed to limp it to the pit lane but you must turn on your hazard lights and check your mirrors before you re-enter the track.
- If you got reported for causing an accident while limping back to the pits and Race Control finds you guilty for insufficient control of your damaged car while limping back to the pits, Race Control will penalize you.
- What to do while limping:
- First, turn on your hazard lights and check if the track is clear behind you: If yes, you can proceed to re-enter the track at a shallow angle parallel to the side of the road from which you came.
- If you are on the left side of the track, continue there until you have enough clear space behind your car (check your mirrors and realtime/substanding apps!) to safely change to the right side of the track, where you will continue until you get to the pit lane.
- Once you get to the pits:
- If you have to make a Long Stop (usually a driver swap) soon anyway, this is the best opportunity to do it because it won't cost you any additional time unlike a normal repair stop
- Normal Repair Stop:
If your suspension is only bent but your wheel did not get ripped out of the car like in the video, you set up the necessary repairs in the pit menu and drive your car into your pit box to make a repair stop - ABSOLUTE EXCEPTION: Unable-to-repair-Teleportation within pit lane
Only in the following specific scenarios that are technically impossible to repair in a normal pit stop, you are allowed to roll the car across the start/finish line inside of the pit lane and stop it in the pit lane before you teleport it to your pit box:- You ripped a wheel out of the car, like in the video
- Your transmission or engine is unrepairably destroyed and you are only coasting with residual momentum (NO, an empty tank does not count: your engine would start again in a normal pit stop the moment it gets the first liter of fuel!)
Option 2: Teleporting to the pits
There are 3 ways to teleport your back to the pits if it's damaged so badly that you cannot limp it back to the pits safely anymore, or your car is completely unable to move under its own power (Examples: no fuel, blown engine, transmission failure).
- Stopping the car, hitting the ESC button & selecting "Back to pits":
You get teleported into the pits and see the UI Menu, which can be closed via a click on the wheel button in the upper left corner. You get a time penalty and can leave the pits with a new repaired car after the end of the penalty. - Using an input button, which is assigned to the Content Manager function "Setup in pits"
You get teleported into the pits and see the UI Menu, which can be closed via a click on the wheel button in the upper left corner. You get a time penalty and can leave the pits with a new repaired car after the end of the penalty. - Using an input button, which is assinged to the Content Manager function "Teleport to pits"
You get teleported into the pits, get a new repaired car and are able to leave the pits immediately but you lose the progress of your current lap.
You can use either of these approaches, but the usage of the input-button-triggered teleportation only allowed directly after an accident. If you have to abort an attempt to limp a damaged car back to the pits after several hundred meters or more, you must stop the car, hit ESC and select "back to pits".
If a driver gets caught (via Stream, Incident Report, Stracker, etc.) using the teleportation features in an improper way or to gain an unfair advantage such as bypassing the duration of a pit stop, race control will investigate it and decide about a penalty, which can go as far as a complete disqualification.
Blue Flag monitoring by Co-Driver in Web Live Timing
You can only trust Assetto Corsa's Blue Flags until your car's first driver swap!
After this, you should rely on outside help from your Co-Driver to filter the Blue Flags, by making them use the ServerManager Live Timing at http://5.75.183.156:8772/live-timing?server=4 to keep track of the cars around you and relay their real race positions to you . This information provided by them is crucial for you to tell apart drivers who are a lap ahead of you (or already lapped by you) from drivers against whom you are fighting for position.
While you are in the car, you can of course use the Kunos F9 Timing App and Realtime-Style apps such as Substanding Relative, but it's a significantly better solution for your co-driver to support you as a spotter! Another option to get a general idea of positions is to follow our livestreams on Youtube, which will be linked as updates in the relevant sections below once their links are available. These streams will additionally be posted in #drivers chat in Discord when they go online.

Best wishes
This is important for me: THR is a volunteer-driven passion project, not a professional organization!
We are experienced in hosting events and we always try to do our best. However, races with so many participants from different communities are a challenge for us as well.
It's possible that some things may not run as smoothly as we hope, or that we can't respond and provide a solution immediately. Rest assured, though, that we try everything so that we can experience a great event together!
And if this one works well, similar events might occasionally happen in the future again. Why not drive in circles for 12 hours, or even longer 😉
We wish you all an intense, exciting and overall really enjoyable Endurance Race!
