The Mercedes-Benz 500I engine is a highly powerful, turbocharged, 3.4-liter, Indy car racing V-8 engine, designed, developed, and built by Ilmor, in partnership with Mercedes-Benz, specifically to compete in the 1994 Indianapolis 500.[2][3][4][5][6][7][8][9][10]

The Mercedes-Benz 500I engine was slightly lighter than the Ilmor 265D Indy V8 it replaced in the Penske PC-23, although because of its longer inlets, the 500I had a higher overall centre of gravity, thus changing the overall balance of the car a bit.[11] The development and testing of the 500I engine, at that time called Ilmor 265E, took place in the utmost secrecy because there was a possibility of the turbocharger boost level being changed, or the engine being banned by the Indy 500 sanctioning body.[11][12]
