The 1975 Formula One season was the 29th season of FIA Formula One motor racing. It featured the 1975 World Championship of F1 Drivers[1] and the 1975 International Cup for F1 Manufacturers[2] which were contested concurrently from 12 January to 5 October over fourteen races. The season also included three non-championship Formula One races and a nine race South African Formula One Championship.
After a strong finish to the 1974 season, many observers felt the Brabham team were favourites going into the new year. An emotional first win for Carlos Pace in his native São Paulo looked to confirm this, but tyre wear frequently hampered the cars and the initial promise was not maintained.[3] In his second year with Ferrari, Niki Lauda was given the keys to the Ferrari 312T, a car that was technically far superior to any of the competition. He won his first drivers' title with five wins and a huge margin over second place in the championship. Ferrari took home the championship trophy for manufacturers. Lauda often referred to 1975 as "the unbelievable year".
American Mark Donohue died in August, two days after crashing in practice for the Austrian Grand Prix.[4][5][6] And after the season, in late November, an Embassy Hill airplane crashed in England and all six aboard were killed, including team owner Graham Hill and driver Tony Brise.[7][8][9]
