After a fair amount of resistance from American teams who generally believed that rear-engine cars were for "drivers who like to be pushed around", the Lotus 38 had proved that mid-engined cars could make the grade at The Brickyard, and the days of the front-engined roadsters were effectively over (in fact, only 4 of the 33 starters in 1965 were front engine cars). Clark won the 1965 Indianapolis 500 with a then race record average speed of 150.686 mph (242.506 km/h), the first time the Indianapolis 500 had been run at a speed of over 150 mph. The previous record had been set by Foyt in 1964 at an average of 147.350 mph (237.137 km/h). Foyt's win in 1964 in a front engine Watson-Offy roadster was the last time a front engined car would win the Indy 500.
