Chasis of Lotus Elan sports car, 1966.
© Science Museum / Science & Society Picture Library
The backbone of this Lotus chasis consists of a very strong deep-sectioned box girder of welded steel, with forks at each end to carry the independent coil spring and wishbone suspension. A light and streamlined glas-fibre two-seater body is mounted onto the chasis. The car's engine produces 115 bhp at 6000 rpm. It has a four-speed syncromesh gearbox, rack and pinion steering and is fitted with Girling disc brakes on the front and rear wheels. Colin Chapman established Lotus Cars in 1951, and this model, the Elan, first appeared in 1962.
