The 1988 March Engineering 88C Indy car was driven to 2nd place in that year’s Indianapolis 500 by Emerson Fittipaldi, and was powered by either a Chevrolet or a Porsche engine that year. The 88C was outclassed by the Lola and Penske chassis that year, but still ran in the Champ Car/IndyCar Series until the end of 1989.
First seen in sim racing with Indy 500 (1989). The manual for Indy 500 states that their March chassis is a March-Cosworth, and this means you replace the March-Cosworth of Rich Vogler, who started 33rd and finished 8th in 1989. Only four of the 33 starters ran March chassis that year, and just three of them with Cosworth power.
