In the opening race at the popular German street venue, Winward Mercedes driver Schumacher was battling with Luca Engstler for 19th position when he made contact with the Audi driver at the apex of Turn 1, sending the 23-year immediately into retirement.
The stewards deemed Schumacher responsible for the collision and handed him a five-second penalty, which dropped him from 14th to outside the points in 16th place.
