Introduced ahead of the 1982 season, the Williams FW08 had big shoes to fill. It replaced the FW07 that had served for three successful seasons. Stronger and more efficient than its rivals, the FW07 had fully harnessed the ground effect aerodynamics pioneered by Team Lotus.
By the early 1980s, most front-running teams were switching to turbocharged engines, but Williams was forced to run the naturally aspirated Cosworth DFV V8 once again. This required the engineering team, led by Patrick Head, to focus on making a stronger, lighter and more aerodynamically efficient Grand Prix car and resulted in the highly effective FW08, which propelled Keke Rosberg to the World Drivers Championship, the last ever for a Cosworth DFV-powered car.
Designed by Neil Oatley and Frank Dernie, the FW08 was a further refinement of its successful predecessor. A World Championship winner in 1980, the FW07 used a very strong aluminium honeycomb monocoque chassis to cope with the aerodynamic forces generated by the ground effect tunnels running through the underbody on either side of the tub. These created a low-pressure area underneath the car using the Venturi effect, resulting in an abundance of efficient downforce, generated without the drag penalty of conventional wings. By 1982, the team faced the new challenge of rivals switching to works-supplied turbocharged engines.
To ensure the team remained competitive against the more potent turbo engines, the engineering team had to combine all the attributes of the FW07 into a more efficient package. The fruit of this labour was the FW08, which was lighter, stronger and more aerodynamically efficient than its predecessor. It was also shorter, partly prompted by the innovative four-wheel rear-end concept that Williams had been testing late in 1981 on a FW07 mule. This would turn the FW08 into a six-wheeler. The obvious benefits included a reduction in drag, improved traction, and longer, downforce-generating ground-effect tunnels.
Crucially, the rear wing could also be mounted further rearward into less disturbed airflow. A downside was the additional 45kg weight of the setup, but Williams chief engineer Patrick Head claimed that the FW08 was designed to weigh 530kg when the legal limit was set at 585kg, so that would not have been a problem.
Going into the 1982 season, Williams focused on the conventional four-wheel FW08. In testing, it proved a vast improvement over the FW07, and lead-driver Keke Rosberg smashed the Brands Hatch Indy lap record with a startling time of 36.3 seconds. The FW08 also reportedly showed well against the turbocharged Renaults and BMW-powered Brabhams on joint test sessions.
Having opted to run the existing FW07Cs at the three fly-away Grands Prix that opened the 1982 Formula 1 World Championship, Williams’ official debut of the FW08 was further delayed by the boycott of the non-turbo teams of the San Marino Grand Prix as a protest against the FISA, the sport's governing body.
The belated debut for the FW08 finally came at the Belgian Grand Prix, where Rosberg qualified third and team-mate Derek Daly in 15th. Rosberg would convert his great starting position by crossing the line in second. In the remaining eleven Grands Prix, Rosberg was very consistent and used the reliable FW08 to finish in the points seven times. Among the four podiums he achieved was a crucial victory in the final Swiss Grand Prix, held at Dijon. The Flying Finn's great run throughout the 1982 season saw him crowned World Champion despite the single victory he scored. A naturally-aspirated engine would not propel a driver or team to a World Championship until the comprehensive rule changes that came into effect in 1989 ending the sport’s first turbo era. Crucially, it was also the last World Championship for the all-conquering Cosworth DFV engine.
During the 1982 season, the four-wheel rear was grafted to this very car for testing. Wind-tunnel tests suggested that with bespoke bodywork, the six-wheeled FW08B would have a 60% lift-to-drag improvement over the already very efficient FW08. If these figures could also be achieved on the track, Dernie suspected the six-wheel FW08 ‘B’ could outrun the more powerful turbocharged cars on the straights. When tested by Jonathan Palmer, the car used existing bodywork but still proved very effective. Sadly, development stopped when the revised sporting regulations stipulated that Formula 1 cars could have no more than four wheels. At the 1995 Goodwood Festival of Speed, Palmer demonstrated what could have been by setting the fastest timed run.
Further rule changes ahead of the 1983 season saw ground effect aerodynamics banned altogether. The changes came rather last minute, which saw Williams create the FW08C using the same monocoque but without the ground effect tunnels. Truly outgunned, Williams and Rosberg were unable to stage an effective title defence, but a works turbo engine deal was finally secured by partnering with Honda.
The FW08 closed the first successful chapter of Williams Grand Prix engineering and did so in style, wearing the iconic Saudia colours and winning the 1982 World Championship with Keke Rosberg at the wheel.
The very first FW08 constructed, this chassis initially served as a practice car for Keke Rosberg during three Grands Prix.
It debuted at the Canadian Grand Prix in Montréal, the Finn qualifying seventh but failing to finish the race due to a rare gearbox failure. During the next three races, it was used by Rosberg in practice only, but then served as his race car again for the crucial, final push to the championship title. At the German Grand Prix, he finished third from ninth on the grid. Starting sixth, he then came achingly close to winning the Austrian Grand Prix, crossing the line side-by-side with Elio de Angelis in the winning Lotus but missing out on victory by a mere 0.050 of a second.
Not used during a Grand Prix weekend again, FW08-01 was then rebuilt to FW08B specification with the six-wheel rear-end. Illustrating how serious a project this was, Patrick Head, Frank Dernie and Neil Oatley were all actively involved - as was a young engineer by the name of Ross Brawn. The car was successfully tested by Jonathan Palmer and Keke Rosberg, but the project was abruptly cancelled when the FIA decreed that a Formula 1 car should have no more than four wheels.
Surplus to requirements, Williams Grand Prix Engineering gifted the car to long-time backer Count Gughi Zanon in March of 1984. Chassis FW08-01 then returned to Williams in November of 1993 and was briefly displayed in the Donington Grand Prix Collection. In 1994, it was demonstrated at the Goodwood Festival of Speed by Jonathan Palmer. He returned the following year to really demonstrate what the car was capable of, winning the hill climb event with the fastest time of 46.06 seconds. In 1997, it was sold to the Brunei Royal Family, only for the car to return to Williams once more in 1999.
In 2000, it was converted back to its original four-wheel configuration and then sold to an American historic racer in 2005. Since then, it has been actively raced by its successive owners on both sides of the Atlantic. It is supremely eligible for all major events, including the Monaco Historic Grand Prix and, being among the very last of the ground effect Grand Prix cars, it is a certain front-runner on any pre-1985 historic grid.
Used exclusively in period by Keke Rosberg on the way to his Formula 1 World Championship and actively involved in the fascinating six-wheeler project, chassis FW08-01 is one of the most significant Williams Grand Prix cars of this era.

Monaco Historique – Série G
The biennial Monaco Historique is the jewel in the crown for historic Formula One cars. Held over three days in early May, this event holds several races, with this Williams FW08 eligible for the Série G grid for Formula One cars constructed between 1981-1985. The next running of the Monaco Historique is set to take place in May 2026.
Masters Racing Legends
For Formula One cars built between 1966-1985, Masters Racing Legends holds a full annual calendar. Events take place at iconic circuits, including Silverstone and Spa. In addition, the series also offers an ever-increasing number of support races at some Formula One grand prix weekends, such as the US and Mexican Grand Prix.
Monterey Motorsports Reunion – Mario Andretti Trophy
This annual event occurs during the iconic Monterey Car Week at the world-renowned Laguna Seca circuit which, in 2025 is officially celebrating Formula One.
