The Lotus 63 was an experimental Formula One car using four-wheel drive, designed by Colin Chapman and Maurice Philippe for the 1969 season.

This was not totally revolutionary 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, but with little development thereafter.

In fact, the Matra MS84 was the only 4WD F1 which scored points (driven by Johnny Servoz-Gavin, at the 1969 Canadian Grand Prix) something neither Lotus nor McLaren managed, while Cosworth did not even race their 4WD design.

[2] The 63 was an evolution of the 49, but featured wedge shaped rear bodywork and integrated wings, which would be used to great effect in the Lotus 72.

John Miles, Lotus' third driver, was entrusted with the task of developing the car, while Graham Hill and Jochen Rindt used the 49 in the early races of 1969.
