Moving up from Formula Two, Fittipaldi made his race debut for Team Lotus as a third driver at the 1970 British Grand Prix. After Jochen Rindt was killed at the 1970 Italian Grand Prix, the Brazilian became Lotus's lead driver in only his fifth Grand Prix. He enjoyed considerable success with Lotus, winning the World Drivers' Championship in 1972 at the age of 25, a youngest F1 world champion record that he held for 33 years. He later moved to McLaren for 1974, winning the title once again. He surprised the paddock by moving to his brother's Fittipaldi Automotive team prior to the 1976 season, being replaced by James Hunt. Success eluded him during his final years in Formula One, with the Fittipaldi cars not competitive enough to fight for victories. Fittipaldi took two more podium finishes, before retiring in 1980.
