ハンス＝ヨアヒム・スタック
Alongside Formula One, Piquet took part in the 1000km Nürburgring in 1980 and 1981 driving a BMW M1. He won the 1981 race alongside the German Hans-Joachim Stuck. However, the race had to be stopped roughly two hours in because of the fatal crash of Herbert Müller after 17 laps of the 14-mile (23 km) course.
