Vel’s Parnelli Jones Racing (VPJ), commonly known simply as Parnelli, was an American motor racing constructor and team that enjoyed success in both USAC Championship Car racing and Formula One. Founded in 1969 by Indianapolis 500 winner Parnelli Jones and businessman Velko “Vel” Miletich, the team became one of the dominant forces in American open-wheel racing before expanding into Formula One during the mid-1970s.
While its Formula One programme lasted only three seasons, VPJ achieved six World Championship points and laid the foundations for one of the most successful racing engines in American motorsport history through its pioneering development of the turbocharged Cosworth DFX.

Success in USAC
Parnelli Jones and Vel Miletich established the team in 1969 with a focus on USAC Championship Car racing. Success arrived almost immediately.
Driving a VPJ Colt, Al Unser dominated the 1970 Indianapolis 500, leading 190 of the race’s 200 laps before claiming victory. The triumph formed part of a championship-winning campaign, establishing VPJ as one of the leading teams in American open-wheel racing.
Unser successfully defended his Indianapolis 500 crown in 1971 with a newly designed Colt built to comply with revised regulations that outlawed the previous chassis offset design. Although Unser finished fourth in the championship that season, teammate Joe Leonard secured the USAC title, giving VPJ another championship-winning campaign.
Formula One
Seeking a new challenge, VPJ recruited former Team Lotus designer Maurice Philippe and future World Champion Mario Andretti during the early 1970s. Philippe’s arrival proved instrumental when the team decided to enter Formula One for the closing races of the 1974 season.
Financial backing from Firestone helped launch the project, while Philippe designed the VPJ4, a car heavily influenced by his highly successful Lotus 72 concept. The new machine made its debut during the 1974 Canadian Grand Prix before becoming the basis of a full Formula One campaign in 1975.
Despite showing encouraging signs of progress, the programme suffered a major setback when Firestone announced its withdrawal from international motorsport at the beginning of the 1975 season. Losing its title sponsor left VPJ struggling financially, and despite continuous development of the VPJ4, the team was unable to secure sufficient backing to continue.
Parnelli remained on the Formula One grid until the opening stages of the 1976 season before withdrawing after the Long Beach Grand Prix. The end came as a surprise even to Mario Andretti, who reportedly first learned that the team was closing from journalist Chris Economaki while sitting on the starting grid. The circumstances created tension between Andretti and Parnelli Jones, with Andretti returning to Lotus for the remainder of the season.
Vel’s Parnelli Jones Racing contested 16 World Championship Grands Prix and scored six championship points, establishing itself as one of the few American constructors to achieve genuine competitiveness during the era.
Cosworth DFX Development
Alongside its Formula One programme, VPJ embarked on an ambitious engineering project that would have an even greater impact on American motorsport.
Working from its headquarters in Torrance, California, the team began developing a turbocharged version of Cosworth’s renowned DFV V8 engine. The programme was led by engine builder Larry Slutter and dyno engineer Takeo “Chickie” Hirashima, combining VPJ’s recent Formula One experience with the demands of Indianapolis racing.
The engine first appeared in a modified VPJ Indy car during 1975 before becoming a regular competitor the following season. Recognising its enormous potential, Cosworth adopted the project and developed it into the Cosworth DFX.
The resulting engine became one of the most successful power units in racing history, winning every Indianapolis 500 between 1978 and 1987 while also powering every USAC and CART champion throughout the same period.
Legacy
Today, VPJ is remembered as one of the most innovative American racing organisations of the 1970s, successfully bridging the worlds of Indianapolis racing and Formula One while helping create one of motorsport’s most dominant engine programmes.
