In 1970, Lotus founder Colin Chapman replaced the venerable Lotus 49 with the radical new Lotus 72. The 'cigar-shape' that had dominated Forumula One for over five years was replaced by a new wedge shape designed to increase downforce and improve cornering. Despite the advancements of the car, lead driver Jochen Rindt was not enamored with it and requested a Lotus 49 for use at the Italian Grand Prix, but it did not show up. He drove the 72 only to suffer a brake failure in practice which sent him into the barriers resulting in fatal injuries. Rindt would posthumously win the 1970 World Championship. The Lotus 72 would be refined over the next five years and prove to be one of the most dominant cars in F1 history.
