BMW became the dominant engine producer in European Formula 2 racing in the 1970s (two-liter formula) and later enjoyed success in Formula 1 as well, winning the world championship in 1983. Both
Formula 2 (normally aspirated) and Formula 1 (turbocharged) engines were based on the block of BMW's in-line four-cylinder production engine.
BMW first became involved in Formula 2 in 1967, using a Lola chassis and a 210-horsepower 1600 cc BMW engine with Apfelbeck-designed cylinder heads. In 1968, the engine would increase to 230
horsepower with the use of a diametrical valve arrangement and mechanical fuel injection.
In 1969, a new BMW/Dornier chassis was developed, which ran alongside the Lola chassis. Engine horsepower was now up to 235 @ 10,400 rpm and BMW scored three second place finishes during the
season.
1970 finally saw real success with this development program. With 248 horsepower @ 10,700 rpm on tap, BMW drivers Hubert Hahne, Dieter Quester, Jo Siffert and Jackie Ickx were a formidable team.
Five overall victories were achieved with the 1600 cc Dornier/BMW Formula 2 cars in 1970 - two by Quester and one each by Hahne, Siffert and Ickx. Hahne finished the season in second place overall.
