March 86C

The March 86C is an open-wheel race car designed by Adrian Newey and built by March Engineering for the 1986 CART Indy Car season, where it proved dominant: the 86C chassis won 14 of the 17 races, took 13 pole positions and carried Bobby Rahal to the 1986 championship and the 1986 Indianapolis 500. It was mainly powered by the Ford-Cosworth DFX turbocharged V8, though some cars used the Buick Indy V6 turbo or the Ilmor-Chevrolet 265-A V8 turbo. The chassis stayed competitive after 1986: teams used it in 1987 and 1988, and when Penske abandoned its own PC-16 at the 1987 Indianapolis 500 and switched back to the 86C, Al Unser Sr. won the race in one, giving the car back-to-back Indy 500 victories. It later saw further use in the American Indycar Series.
