1982 BMW M12/13 1.5 Liter 4-cylinder Turbocharged F1 Engine

“Taking a four-cylinder displacing only 1.5 litres and based on a standard production block, the team of specialists around engine “wizard” Paul Rosche created a Formula 1 power unit developing staggering output of 800 hp. The secret behind this mind-boggling performance was the combination of 16-valve technology and a turbocharger masterminded for the first time in Formula 1 by Digital Motor Electronics.”

“The first training car was put through its paces in practice just a year later and in 1982 Brabham entered the first Grand Prix with a BMW engine. Right from the start, this turbocharged power unit proved its supremacy on the track, with the greatest triumph following in 1983: Just 630 days after BMW’s Formula 1 engine had made its first appearance, Brazilian driver Nelson Piquet won the World Championship in a Brabham BMW. And up to 1987 BMW brought home a total 9 Grand Prix wins with this successful machine.”

“BMW M turbo engines did not only go to the Brabham Team. Arrows also used the M power machine from 1984 to 1986, just like ATS in 1983/84 and Ligier in 1987. In 1986, Gerhard Berger won the race in Mexico in a Benetton car, marking the last triumph of this turbocharged power unit. A year later Road and Track, the US car journal, demonstrated the supreme performance of the Benetton B 186 with Teo Fabi at the wheel: Powered by 900 hp, Fabi’s monoposto accelerated to 100 mph (160 km/h) in exactly 4.8 seconds. And Paul Rosche was confident that this four-cylinder was able to develop a lot more power in practice: “It must have been about 1,400 hp, but we don’t know the exact figure since the engine dynamometer didn’t go beyond 1280 hp.”” via
