Lotus 64

The Lotus 64 was an Indianapolis 500 car, designed by Colin Chapman and Maurice Philippe for the 1969 race. The car was meant to be a successor to the Lotus 56, using a normal Ford V8 while retaining the 4 wheel drive.

As the Lotus 56, the 64 chassis was designed around a four wheel drive system. This was no revolution at the time, as four wheel drive had been used on the Ferguson P99 F1 car that won at Oulton Park as early as 1961. However, it was not a successful design, and was believed to be excessively heavy. Mario Andretti crashed heavily in the car during practice, and all three of the 64s were withdrawn. Andretti later won the race in the team's backup Hawk chassis.
