Williams FW07

The car made its debut at the Spanish Grand Prix at Jarama in 1979, the fifth round of the season and the first European round after the non-ground effect FW06 was used for the first four rounds in the Americas and South Africa. The car proved to be reasonably competitive; Australian Alan Jones put the car 13th at Jarama and then 4th for the next round in Belgium; he even led 16 laps of the race before retiring with electrical failure. But when the British Grand Prix at Silverstone came around, chief designer Frank Dernie had designed and implemented a system that ensured that the car's all-important skirts touched the ground at all times and had also corrected some aerodynamic leakage at the back of the chassis between the French and British Grand Prix. Jones then stuck the revised Williams on pole and was immediately 2 seconds faster than the next fastest car. The car served to make Team Williams a contender for the first time; Jones retired with fuel pump failure and his Swiss teammate Clay Regazzoni won his last Grand Prix and first since 1976. [2] Jones then won 4 of the next 5 Grand Prix in Germany, Austria, Holland and Canada in a car that was so much quicker than any of the others, particularly around high-speed circuits. But because the car's competitiveness came only at mid-season, Jones and Williams lost the driver's and constructor's championships to South African Jody Scheckter and Ferrari, respectively. But the FW07's competitiveness meant that Williams was a top contender for the 1980 season and beyond.[3] The FW07 was similar to the Lotus 79 which had won both titles during the 1978 Formula One season, but had a stiffer chassis.[4]

The Williams FW07 (1979).

The Williams FW07B (1980).

The FW07 became FW07B in 1980, and Regazzoni was replaced by Carlos Reutemann. While the latter and Williams's other driver, Alan Jones, formed a successful partnership, they were not comfortable with each other. Both drivers developed the FW07 further, working especially on setup and suspension strengthening. The car was now so efficient in creating downforce from its ground effect design that the front wings were unnecessary. Jones won five races in Argentina, France, Britain, Canada and Watkins Glen in the USA to win his only world championship, while Reutemann won at a wet race in Monaco. Williams won also their first Constructors' Championship. The main challenge to the FW07 came from Nelson Piquet in Brabham's neat BT49.[5]

The FW07B evolved into the FW07C for 1981, and this time it was Reutemann who challenged Piquet for the championship, narrowly missing out in the final race, but Williams took home the constructors' championship after four more wins. Further work was done to the suspension, especially after the FIA banned the moveable skirts needed for effective ground effect. The hydraulic suspension systems were developed by Jones, who hated the rock hard suspension. During a winter test session at the Paul Ricard Circuit in the south of France, he suggested to Frank Williams that to compensate for the harsh ride and the pounding the driver gets while driving the car that he "put suspension on the seat", which Frank thought was a good idea. However, he then replied that Jones should sit on his wallet. 'Yeah,' drawled the tough Aussie, 'then give me something to put in it!'[6] Jones temporarily left Formula One because of the extremely unpleasant ride the FW07C gave, he later described driving the car as "wrecking the internals".[7] The FW07C was the second fastest car of 1981, behind the Renault RE30, but the Williams was more reliable.[4]

BBC's Horizon series followed the team during winter testing, and later produced the film Gentlemen, Lift Your Skirts which was broadcast during 1981. The film featured extensive behind the scenes footage of the team at work and interviews with the drivers, Frank Williams and Patrick Head.[8]

The FW07D was an experimental six-wheeled test car (four driven rear wheels, and two undriven front wheels) tested by Alan Jones on a single occasion at the Donington Park circuit. With the FW07D proving the concept, its unique design was incorporated into the six-wheeled FW08B.[9][10]

After Jones retired, Williams took on Keke Rosberg in 1982. His mercurial driving seemed to suit the FW07, which although it was now three years old, was still competitive. After 15 wins, 300 points, one drivers' and two constructors' titles the FW07 was replaced by the similarly engineered FW08 from early 1982.
