BMW E41 / P80 engine
The BMW M12/13 turbo was a 1,499.8 cc four-cylinder turbocharged Formula One engine, based on the standard BMW M10 engine introduced in 1961, and powered the F1 cars of Brabham, Arrows and Benetton. Nelson Piquet won the FIA Formula One Drivers' Championship in 1983 driving a Brabham powered by the BMW M12/13 turbo. It was the first Drivers' Championship to be won using a turbocharged engine. The engine also powered the BMW GTP and in the 2.0-litre naturally-aspirated form, the successful March Engineering Formula Two cars. BMW engineers estimated the engine produced around 1,400 hp at maximum boost, however the BMW engine dynamometer could not go beyond 1,280 bhp.[5][6][7][8]
