Rolf Stommelen
While competing in Formula Two in 1982, Bellof made a one-off appearance in the World Endurance Championship at the 1000 km of Spa, partnering Rolf Stommelen at the wheel of a Kremer CK5. The pairing retired from the race on lap 51, due to a problem with the starter motor. The previous weekend, Bellof had joined Kremer to compete in the Hessen Cup at Hockenheim as part of the Deutsche Rennsport Meisterschaft, but retired with transmission failure.
