Registration
The registration logic between the Championship Main Events (Sunday) and Practice Race Events (Saturday) is the same:
- You have to renew your registration for each event of the championship
- Separate registration lists between Saturday (Practice Races) and Sunday (Championship Race after Weekday Qualifying)
- Registrations for every race weekend usually open on Monday of the same week
- After submitting your registration for this week's championship event, you can immediately join the championship qualifying server by default* **
*Usually, you will immediately be able to connect to the qualifying server successfully. Until the next automatic 2-hourly restart of the qualifying server, you might see a different skin than the booked one on your car on this server. This condition always gets corrected by the next 2-hourly autorestart of the server.
**Only in rare cases, joining will continue to fail with the message "No slots available". If this continues to happen more than 2 hours after submitting your championship event registration for the week, please inform the @Orga team in our community discord's #drivers channel.

Cars
Brabham BT44-B
In the 1960s, Brabham dominated open-wheel racing car sales, building over 500 cars used in Formula Two, Formula Three, Indianapolis 500, and Formula 5000. Gordon Murray's aerodynamically clean Brabham BT44, a simple Ford DFV/Hewland design sponsored by Martini, achieved success in Formula One. Carlos Reutemann secured 3 wins in 1974, leading Brabham to fifth in the Constructor's Championship. In 1975, Carlos Pace won in Brazil, Reutemann won at the Nürburgring, and Reutemann finished third in the drivers' championship, with Brabham again fifth in the constructors' championship. While competitive, the BT44 couldn't surpass the McLaren M23 or Ferrari 312T.
BRM P201
BRM, founded in 1945, competed in Formula One from 1950 to 1977, winning seventeen grands prix and the 1962 constructors' title with Graham Hill. Mike Pilbeam designed the BRM P201 for 1974, featuring a triangular monocoque and excellent handling, but its outdated V12 engine lacked power. Jean-Pierre Beltoise debuted the P201 impressively, qualifying 11th and finishing a sensational second place, highlighting the car's handling prowess despite its engine limitations. BRM's final season under Owen Organisation ownership dwindled, and the team later became the Louis Stanley's Stanley-BRM operation.
Embassy Hill GH1
Embassy Hill, Graham Hill's short-lived Formula One team, debuted in 1973 and began constructing its own chassis in 1975. The Hill GH1, an evolution of the Lola T370 designed by Andy Smallman, featured a straightforward monocoque, Ford Cosworth DFV engine, and conventional aerodynamics. After struggles with the Lola and Hill's retirement after failing to qualify in Monaco, Tony Brise and Alan Jones joined as drivers. They managed three points, with Brise finishing sixth in Sweden and Jones fifth in Germany. Sponsorship from Embassy cigarettes aided the team, but their progress was tragically cut short by a fatal plane crash involving Hill, Brise, and key personnel before the 1976 season.
Ferrari 312T
The year of the 312 T, where the T stood for the transversal gearbox, in a 90-degree angle to the engine. This solution led to a compact engine and an improved weight distribution and a very fast and agile car, but also quite nervous and difficult to drive to the limit.
After 11 years the Scuderia regained the Drivers’ Title with Niki Lauda, thanks to his 5 wins, 8 places on the podium, 9 pole positions and 12 times in the points in 14 races.
The Constructors’ Title was won thanks to the contribution of Clay Regazzoni, who won the Italian GP. This was the end of the domination by V8s with the first V12-cylinder winning the Championship with almost 500bhp.
Fittipaldi FD03
Fittipaldi Automotive, or Copersucar, was Brazil's only Formula One team and constructor, founded by the Fittipaldi brothers in 1973 with strong Brazilian support. Richard Divila designed the Copersucar-branded FD01, utilizing Embraer's materials and wind-tunnel facilities. Based in Brazil under team manager Jo Ramírez, the team unveiled its silver, rainbow-striped car in 1974. Emerson Fittipaldi shocked the racing world by joining the team in 1976. Keke Rosberg achieved his first podium with the team, and the FD series cars achieved a best finish of fourth at the 1977 Argentine and Brazilian Grands Prix (Emerson Fittipaldi) and scored a total of 11 World Championship points.
Hesketh 308
Hesketh Racing, a British Formula One constructor from 1973-1978, participated in 52 Grands Prix, securing one win and eight podiums, peaking at fourth in the 1975 Constructors’ Championship. James Hunt debuted and achieved most of his success with Hesketh; Alan Jones also began his F1 career in a privately entered Hesketh. The 308, designed to replace the March 731, featured a Ford-Cosworth DFV engine and innovative rubber springs developed by the Malaysian Rubber Producers Association and Aeon Products. Hunt secured pole position at the 1974 Race of Champions and won the International Trophy at Silverstone. However, despite its initial speed, the 308 proved unreliable due to frequent transmission failures throughout the Grand Prix season.
Lotus 72E
The Lotus 72, Colin Chapman's innovative design, featured inboard brakes, side-mounted radiators, and a wedge-shaped profile inspired by the Lotus 56 and 63, resulting in superior aerodynamics and speed. Using the Lotus 49's stressed engine layout and advanced aerodynamics, the 72 overcame initial handling issues caused by anti-dive and anti-squat suspension, becoming a sensation. Intended replacements, like the Lotus 76, faltered, leading to further development of the 72. Peterson won three more races in 1974, while Ickx provided support. The aging 72 performed strongly in 1975 and was outmatched by newer cars like the Ferrari 312T and Brabham BT44, leading to a sixth-place finish in the constructors' championship. After a remarkable career, the 72 was replaced by the Lotus 77 for 1976.
March 751
March Engineering, a British Formula One constructor and customer racing car manufacturer, found moderate success in F1 but excelled in Formula Two, Formula Three, IndyCar, and IMSA GTP. In 1974, the factory team fielded Howden Ganley, Hans-Joachim Stuck, and Vittorio Brambilla, whose accidents proved costly. BMW's push for March to focus on F2 coincided with Patrick Depailler's F2 championship win in an Elf-sponsored March-BMW. In 1975, Brambilla surprisingly won the Austrian Grand Prix, and Lella Lombardi became the only woman to score a Championship point in F1 at the shortened Spanish Grand Prix. The year was also marked by Mark Donohue's death in a Penske-owned March. March provided privateers with simple, fast, and economical cars in the mid-Seventies, despite chassis inconsistencies.
McLaren M23
McLaren, founded by Bruce McLaren in 1963, achieved early success in Can-Am (1967-1971) and Indianapolis 500 (1972, 1974, 1976). After McLaren's death in 1970, Teddy Mayer led the team to its first Formula One Constructors' Championship in 1974, with Emerson Fittipaldi winning the Drivers’ Championship in 1974 and James Hunt in 1976. A long standing sponorship with Phillip Morris’ Marlboro cigarette brand started in 1974. The McLaren M23, designed by Gordon Coppuck and influenced by the McLaren M16 Indycar, featured a Nicholson-McLaren Engines-tuned Ford Cosworth DFV. Introduced in 1973, the car achieved three wins. Fittipaldi's arrival in 1974 helped McLaren win both championships. Developments like a 6-speed gearbox in 1975 placed Fittipaldi second in the drivers' championship and McLaren third in the constructors' championship. Hunt replaced Fittipaldi in 1976 and won the championship with the M23D.
Parnelli VPJ4
Vel's Parnelli Jones Racing (VPJ), formed in 1969 by Parnelli Jones and Vel Miletich, initially focused on USAC racing, achieving success with Al Unser's 1970 Indianapolis 500 win and championship. Unser repeated the Indy 500 win in 1971 with a nearly identical Colt. Debuting in F1 in 1974, the VPJ4 had a rocky start. In 1975, Mario Andretti faced numerous retirements and managed to score points with a fourth-place finish in Sweden and a fifth-place finish in France. The Parnelli team ultimately scored five World Championship points, placing tenth in the Constructors' Championship.
Penske PC1
The Penske PC1, designed by Geoff Ferris, was a Formula One car raced by Penske Racing during the 1974 and 1975 seasons. Founded in 1968 by Roger Penske, the team remains the last American team to win a Formula One Grand Prix (1976 Austrian Grand Prix). Penske acquired McRae Cars Ltd in 1973, appointing Heinz Hofer as F1 manager and assembling a team including Geoff Ferris and Karl Kainhofer. The PC1, an aluminum monocoque with a Ford Cosworth DFV engine and Hewland gearbox, debuted at the 1974 Canadian Grand Prix with Mark Donohue, who returned to racing after previously driving in a Penske-sponsored McLaren in 1971.
Shadow DN5
Shadow Racing Cars, an American-founded Formula One and sports car team that later operated from Britain, was the first constructor to officially change nationality. The Shadow DN5, a Formula One car used during the 1975 season and updated through 1977, achieved three pole positions and two fastest laps. Tom Pryce achieved the DN5's best finish: third place twice. Despite Jean-Pierre Jarier securing two pole positions and fastest lap in the DN5 early in 1975, its poor reliability plagued the season. Jarier only finished two races, and his best finish was fourth at the Spanish Grand Prix (receiving half points). Pryce, however, achieved several finishes, including three sixth places, a fourth in Germany, and a third in Austria. Pryce qualified on pole at the British Grand Prix but retired from the lead.
Surtees TS16
The Surtees Racing Organisation, a race team active from 1970 to 1978, participated in Formula One, Formula 2, and Formula 5000. The Surtees TS16, designed by John Surtees, served as the team's Formula One car from 1974 to 1976. After finishing 11th in 1974, Surtees scaled back to a single car for John Watson in 1975 due to financial constraints. The 1975 season was unremarkable with Watson facing disqualifications, retirements, and lower end finishes; they skipped several rounds to focus on 1976 and the TS16 was replaced by the Surtees TS19.
Tyrrell 007
The Tyrrell Racing Organisation, founded by Ken Tyrrell in 1958, began constructing its own Formula One cars in 1970, achieving early success with Jackie Stewart. The Tyrrell 007, designed by Derek Gardner, was raced from 1974 to 1977. Following Stewart's retirement and François Cevert's death in 1973, Tyrrell signed Jody Scheckter and Patrick Depailler. The team used the earlier 005 and 006 chassis for the first three races of 1974 before debuting the 007 at the Spanish Grand Prix. In 1975, the Tyrrell team scored twenty-five World Championship points, earning them fifth place in the Constructors' Championship standings.
Tyrrell P34
In the mid-1970s, F1 regulations limited front wing width to 1.5 meters, resulting in front tires protruding beyond the wing. The Tyrrell P34's concept involved using smaller, 10-inch diameter tires to fit entirely behind the wing, reducing drag and improving airflow to the rear wing. To compensate for the smaller tires' reduced contact patch, four front wheels were used, also increasing braking area. A bell crank connected the rear pair of front wheels to the steering wheel, and after more tests, Tyrrell constructed two slightly longer wheelbase versions for the 1976 season.
Williams FW03
The Williams FW04, a development of the Williams FW, was used by Frank Williams Racing Cars during the 1975 and 1976 seasons and finished second at the 1975 German Grand Prix. Hampered by a low budget, the team debuted the FW04 at the 1975 Spanish Grand Prix with Arturo Merzario, and the team only built two FW04s. Jacques Laffite replaced Tony Brise, but the team suffered DNQs. Scheckter crashed the car and Laffite had repeated retirements throughout the season until his surprise second-place finish at the German Grand Prix. With six points, Williams finished ninth in the Constructors' Championship for the 1975 season.
Balance of Performance (BoP)
The BoP that we will use during this championship has been made thanks to multiple testing at Dijon and Silverstone. Both tracks offer different characteristics and make it possible to balance the cars. However, be aware that no BoP can be perfect, specifically in a short period of testing. Many factors play a part in how cars are driving, and some drivers may find loopholes in setups or such, that we cannot anticipate. We made our bast to make each car as close as possible, but some cars are easier to drive than others.
Some of them will be fast in straight lines, others will have better cornering abilities. Don't be afraid if your car seem very slow compared to others at first glance.
These cars can be separated in two categories :
some cars are good with understeer, you have to force it more than usually to go around fast in corners (Williams, Brabham, BRM, March, for example)
some cars need a pointy front end and a light rear end (Embassy, Parnelli, Penske, Tyrrell 007, for example), and can be very fast with powerslide
So, take your time while testing them and choose the car that fit your driving style better, more than focusing on one lap pace. Be careful on how your tires wear too because they tend to overheat if you push them too much.

Navigating through the banked Turn 1 and the long, uphill climb out of Turn 2 demands the car and driver need to work in harmony. Mastering Interlagos requires a deep understanding of the car's setup and a brave commitment to carrying speed through its daunting curves.
Kyalami
Nestled in the hills outside Johannesburg, Kyalami is a circuit that rewards power and precision. Long straights and sweeping curves demand a well-balanced car capable of high speeds. The braking zones are critical, requiring drivers to maximize their stopping power while maintaining momentum. The challenging downhill section leading into the final corner requires a careful balance of speed and control, setting up the run onto the main straight. Kyalami is a true driver's circuit, where the ability to extract every last ounce of performance from both car and driver is essential for success.
Montjuic
A legendary street circuit etched into the hills of Barcelona, Montjuïc is not for the faint of heart. Its narrow, winding layout, lined with unforgiving barriers, demands pinpoint accuracy and nerves of steel. The track's constant changes in elevation add another layer of complexity, requiring drivers to be constantly aware of their car's balance and grip. Overtaking is a perilous undertaking, demanding bravery and careful calculation. A single mistake can spell disaster, making consistency and precision paramount. Montjuïc is a test of skill, courage, and unwavering focus.
Silverstone
A hallowed ground of motorsport, Silverstone is a fast, flowing circuit that rewards commitment and bravery. The track's iconic corners, like Copse and Becketts, demand a car with exceptional aerodynamic grip and a driver willing to push to the limit. The long straights offer opportunities for overtaking, but the fast corners require precise car placement and unwavering confidence. Mastering Silverstone requires a deep understanding of the car's setup and a commitment to carrying maximum speed through its daunting curves. Silverstone is where legends are made and legends are forged.
Spielberg
A high-speed blast through the breathtaking Austrian countryside, the Österreichring, is a circuit that demands courage and commitment. Sweeping corners and significant elevation changes test both car and driver to their limits. The long straights offer opportunities for overtaking, but the fast corners require unwavering focus and precise car placement. The circuit's demanding nature and unforgiving surface demand respect, making car setup and driver stamina essential for success. It's a place of both awe-inspiring beauty and heart-stopping danger.
Zandvoort
A unique challenge nestled in the Dutch dunes, Zandvoort is a circuit that rewards both skill and bravery. Its blend of fast corners, banked turns, and unpredictable weather conditions demands a versatile car and a driver with exceptional adaptability. The Scheivlak corner, a blind, banked curve, is a true test of nerve, requiring unwavering commitment and pinpoint accuracy. The undulating layout and sandy runoff areas punish even the slightest mistake. Mastering Zandvoort requires a deep understanding of the car's setup and a willingness to push to the absolute limit.
