The Parnelli VPJ2 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 1973 and 1974. It was driven by Jan Opperman, Mario Andretti, and Al Unser. It was powered by an Offenhauser four-cylinder turbo engine, reputed to develop between 800–1,300 hp (600–970 kW), depending on turbo boost pressure levels.
