ハンス＝ヨアヒム・スタック
1979 saw Hans-Joachim Stuck arrive, to drive a single car. The new Giacomo Caliri-designed D2 arrived mid-season but it was an ill-handling car, with Stuck taking the team's only points score of the season with 5th place at the United States Grand Prix in another new car, the D3, courtesy of Nigel Stroud.
