It's the early 1980's, pastel suits haven't yet come into fashion and BMW has teamed Brabham, who supplied a the chassis, to create what started as a shaky F1 team into a World Champion. With Nelson Piquet and Ricardo Patrese as drivers in the BT-5X cars powered by the 4-cylinder BMW M10 engine. The M10 had been around for nearly 26 years at that point and gone from 75HP in the BMW 1600's to pushing out close to 1,500HP once turbocharged. In 1983, after the age of ground effects has just disappeared and the arrow-shaped Brabham BMW of Nelson Piquet proved nearly unbeatable.
