In 1975, the SloveniannaturalizedCanadian businessman Walter Wolf had started to appear at many of the F1 races during the season. A year later, he bought 60% of Frank Williams Racing Cars while agreeing to keep Frank Williams as manager of the team. Simultaneously, Wolf bought the assets of Hesketh Racing who had withdrawn from F1 due to financial issues and bought some equipment from Embassy Hill, after they had shut down their F1 team following a plane crash that killed six people including team owner Graham Hill and his driver Tony Brise. The team was based in the Williams facility at Reading but used most of the cars and equipment once owned by Hesketh Racing. The Hesketh 308C became known as the Wolf–Williams FW05 and soon afterwards Harvey Postlethwaite arrived as chief engineer. Jacky Ickx and Frenchman Michel Leclère were hired to drive. The team, however, was not very competitive and failed to qualify at a number of races during the year. Leclère left after the French Grand Prix and was replaced by Arturo Merzario while Ickx failed to perform and was dropped after the British Grand Prix, to be followed by a string of pay drivers.
Around this time, the team developed the WD1 sports car for Can-Am racing. The car was developed with Italian firm Dallara.[4]
1978–79
The team remained the same for the 1978 season. Postlethwaite produced the WR5, a new car for the ground-effects era. This did not appear until the Belgian GP. Scheckter finished fourth in Spain and second in Germany but the WR5 soon made way for the WR6 with which he ended the year with a third in the US Grand Prix and second in Canada. He finished seventh in the World Championship.
In 1979, Scheckter was signed up by Ferrari and Wolf signed James Hunt to replace him. Postlethwaite designed the WR7 which ran with Olympus sponsorship. The car was not very successful and retired more than 7 times during the first half of the season. The WR8 soon followed. In mid-season Hunt decided to retire and Wolf quickly hired Keke Rosberg to replace him. The appearance of the WR9 did little to change the team's fortunes and at the end of the year Wolf grew tired of his F1 adventure and sold the team to Wilson and Emerson Fittipaldi, who merged its assets into Fittipaldi Automotive.
As of 2015, a Wolf Racing WR4 is being shown and raced at vintage F1 car events in the United States, campaigned by MotoGP world champion Eddie Lawson.[5]
James Hunt's WR7 is on display at Brooklands Museum, Surrey, UK.
Other motorsport ventures
Walter Wolf was also involved in production cars, providing assistance to Lamborghini to develop the Countach in 1978 when the Italian constructor teetered on the brink of bankruptcy.[6]
Although World Championship races held in 1952 and 1953 were run to Formula Two regulations, constructors who only participated during this period are included herein to maintain Championship continuity. Constructors whose only participation in the World Championship was in the Indianapolis 500 races between 1950 and 1960 are not listed.
