With the help of Jochen Neerpasch, Rosche tried to encourage BMW to enter Formula One using the M12 turbocharged engine, which was based on the M10 engine. When this bid failed, Neerpasch resigned and was replaced by Dieter Stappert, who persuaded the board to attempt the project again in 1980. The engine was tested at the end of the year and made its debut in 1982, winning its first race soon after with Nelson Piquet at the Canadian Grand Prix. This engine went on to achieve another eight wins in F1, as well as leading Piquet to his second World Championship title in 1983. The BMW engine later produced the biggest power output in F1 history (a peak speculated at 1500 bhp and confirmed at 1300bhp).
