The Parnelli VPJ1 is an open-wheel race car, designed by British designer and engineer Maurice Phillippe for Vel's Parnelli Jones Racing, to compete in U.S.A.C. Championship Car, between 1972. It was driven by Mario Andretti and Al Unser. It was powered by an Offenhauser four-cylinder turbo engine, reputed to develop between 1,200–1,300 hp (890–970 kW), depending on turbo boost pressure levels. It didn't win any races, but did score three podium finishes; two for Unser at Indianapolis and Pocono, and one for Andretti at Phoenix.[1][2][3][4]
