Team story
Origins
In 1975, Frank Williams’s name appeared on the cars that had raced as Iso-Marlboros. This was not yet the Williams founded with Patrick Head in 1977: it was his earlier venture, built around purchased single-seaters and in-house programmes often constrained by funding. Arturo Merzario and Jacques Laffite began the season with the FW family, while a new car was being prepared for the next step.
The Formula 1 journey
The FW04 made its debut at the Spanish Grand Prix. Merzario subsequently preferred to return to the older FW03 and left the team; Laffite became the new car’s main driver. At the Nürburgring in 1975 he took second place behind Carlos Reutemann: amid retirements and problems for his rivals, it was this venture’s best result.
The second car, meanwhile, had a succession of drivers, from Ian Scheckter to Renzo Zorzi.
Historical timeline
Three chapters in the story of Frank Williams Racing Cars
Three episodes to revisit the people, cars and races that shaped this journey.
First appearance · Argentine Grand Prix
Arturo Merzario · Argentine Grand Prix 1975. The recorded outcome is NC. This is the first recorded race start, or the first entry if the team never started a race.
Sporting landmark · German Grand Prix
Jacques Laffite · German Grand Prix 1975. The recorded position is P2; this number alone does not show whether the driver completed the race distance. This marks the first win or podium where one exists, otherwise the highest recorded placing for this constructor.
Latest recorded appearance · Italian Grand Prix
Jacques Laffite · Italian Grand Prix 1975. The recorded outcome is DNF. This is the last race start attributed to this constructor in the archive, not necessarily the end of the organisation behind it.
A distinctive way of racing
Ray Stokoe designed the FW04 drawing on experience with John Clarke’s IR/FW cars. The monocoque became narrower, the fuel tanks were repositioned, and the radiators and front suspension geometry changed. The Cosworth DFV remained the engine.
The shared designation did not therefore mean an unchanged car: the FW04 sought to address specific problems with the previous generation, with resources still insufficient for continuous development.
What remains
Walter Wolf’s arrival at the end of 1975 changed the ownership and programme, also bringing in the Hesketh 308C project. The FW04s subsequently passed to Brian McGuire and British Shellsport racing. Laffite’s podium belongs to this first organisation; the future Williams team’s titles are not its statistical continuation.
It remains a distinct phase in which Williams learnt to build cars before his decisive partnership with Head.
