A single seater Formula 1 racing car. Ignoring the unsuccessful work carried out by BRM, Colin Chapman attempted to introduce a 4 wheel drive car to Formula 1, to replace the Type 49. The car had an aluminium monocoque chassis with a 2993cc Ford DFV engine and a Hewland 5 speed ZF transmission and 4WD torque split diff. The car was heavy and difficult to drive. The driver's had to place their feet beneath the front axle, in order to reach the pedals. Both Graham Hill and Jochen Rindt were reluctant to drive it and spent most of the 1969 season driving the older Type 49.
