DieterQuester

Dietrich Erwin Quester (born 30 May 1939) is an Austrian former racing driver. Quester participated in 53 24-Hour Races. He competed in a single Formula One race in which he finished ninth. Starting with motorboats in the 1950s, Quester became part of the Formula 2 team of BMW which intended to take part in the 1969 German Grand Prix. Teammate Gerhard Mitter was killed at the Nürburgring while practising with the BMW 269, though. As a suspension or steering failure was suspected, the BMW team with Quester and Hubert Hahne withdrew from the race, as did Mitter's teammate at Porsche, Hans Herrmann. Quester participated in his home 1974 Austrian Grand Prix on 18 August 1974. He out-qualified his three team mates at Surtees and finished ninth ahead of Hans-Joachim Stuck and double World Champion Graham Hill in the race, but scored no championship points. Quester then focused again on European Touring Car Championship to drive a BMW 3.0 CSL for Schnitzer Motorsport. Quester had already won the 1973 Spa 24 Hours. Later racing in the DTM, he once slid on the roof of his BMW M3 over the start/finish line of the AVUS for a third place.
