Schubert BMW driver Rast was fighting with Engel for ninth position on the second lap of the race when he pushed his Landgraf Mercedes rival wide and over the grass at the exit of Hasseroder.
Engel rejoined the track uncontrollably and tapped Rast’s BMW, although it was Engel who came off worse, with the rear of his Mercedes stepping out on the short dash towards the next left-hander.
