In 1980, BMW announced their development of a turbocharged motor for the Brabham F1 team. The BMW M12 engine first raced in the 1982 season. The M12/13 engine won at the 1982 Canadian Grand Prix at the hands of Nelson Piquet; Riccardo Patrese was the team's other driver. The following season, BMW supplied engines to the ATS team; the factory-backed Brabham took four victories on its way to Piquet's championship win. Two more victories came in 1984, and BMW added Arrows to its list of teams who received its engines. In 1985, Piquet's Brabham, who was now teamed with Marc Surer, managed only one win.
