ヘルムート・マルコ
After a successful karting career in which he won numerous Australian state and national titles, Schuppan made the decision to pursue a career in motor racing. He and his wife Jennifer ventured to Great Britain (with a self-imposed 2-year limit of making it big) to allow him to participate in the British Formula Atlantic Championship, which he won, leading to a test with BRM. As BRM's test driver he qualified for the 1972 Belgian Grand Prix at Nivelles-Baulers, but he did not start the race because teammate Helmut Marko commandeered his car, though he did compete in some non-championship races with BRM.
