To conform to the rules, Chapman had to retain the Seven's chassis, engine, gearbox, and differential. With the assistance of Nigel and Michael Allen, he modified the car to the limits of the rules. Chapman boxed the frame rails and added 14-gauge tubular cross-members for torsional stiffness. A sleek aluminium two-seater body, which weighed only 65 lbs. (29.5 kg), was added to cut down drag, and the engine was extensively modified to produce more power. The car, for all its seeming delicacy, proved startlingly faster than the competition. It led to a demand for copies (an improved Mark IIIB (registered as ONK 408) was built for Adam Currie, for instance, was the first Lotus to be sold to a customer and the first car to wear the Lotus badge), as well as copies of the earlier Mark I. By the end of the racing season, it was apparent the Mark III was the best 750 Formula car in England. -- Last edit: 2025-12-03 01:22:45
