Lotus Mark I

[1] Chapman built the body utilizing a composite made of thin aluminium bonded to plywood.

His approach to automobile construction using sound engineering principles and ingenious chassis design set the stage for many more revolutionary designs to follow.

Although the original Mark I has been lost to history after being bought by a mysterious buyer in 1950, a replica (see photo) was created to the same dimensions that uses an identical Austin chassis and running gear.

Chapman and his future wife competed with the car in English Trials, a form of competition over rough terrain against time.

First larger wheels and tyres were fitted and the front beam axle was split and hinged in the centre to provide independent front suspension.
