A drivers whose career was almost exclusively spent driving sports cars made or powered by BMW, Hahne’s reputation was forged racing the works BMW 1800Ti touring car in the 1964-6 European championship seasons.
Given the opportunity to race in the German Grand Prix in 1966 in a Formula 2-spec Tyrrell Matra, Hahne finished an excellent second in class and was inspired to move into single-seater competition, becoming the works driver in a Lola BMW in 1967 before he moved back to tin-tops.
Hahne returned to open-wheeled competition in 1969 with BMW’s own Formula 2 challenger, taking two second places at Hockenheim, but he was withdrawn from the 1969 Grand Prix after team-mate Gerhard Mitter was sadly killed.
He stayed on in Formula 2 in 1970, winning the Rhine Cup race at Hockenheim, which was clearly a favourite circuit of his. He took delivery of a March 701 for that year’s German Grand Prix, and there was consternation when he failed to qualify at a circuit where he was expected to perform well. A furious Hahne threatened legal action and claimed the car was delivered to him in an unraceworthy state, but Ronnie Peterson took the same car for a test later on and it was perfectly fine.
Humiliated, Hahne quit motorsport on the spot.
