The son of the great prewar Auto Union ace of the same name, Stuck made his name as a touring car driver for Ford and BMW in the early 1970s, his victories including the 1972 Spa 24 Hours. With the support of BMW he moved to single-seaters and in 1974 he finished second in the European Formula 2 series to Patrick Depailler. He made his F1 debut that year with the March team and he continued to drive for the team on an irregular basis until 1977, while also continuing to compete for BMW in touring car racing and in IMSA. In 1977 he joined the Brabham-Alfa Romeo team after the death of Carlos Pace and scored splendid third places in the German and Austrian Grands Prix, plus a fifth in the British. He was storming away with the rain-soaked US Grand Prix at Watkins Glen until he crashed out of the lead.
