ADAC German Formula 4
Joey Mawson recorded his seventh win of the season as he maintained his lead in the ADAC German Formula 4 Championship.
The Sydney racer kicked off the weekend by following title rival Mick Schumacher, the son of Formula 1 legend Michael, home in the opening heat at the Nurburgring.
However, Mawson showed his class in the second race as he took victory despite contact with Schumacher.
Schumacher tried an ambitious move for the lead on Mawson which forced the Australian wide.
Mawson fought his way to fifth from ninth on the grid in the final race before he was issued with a post-race 30 second penalty.
Officials deemed the Van Amersfoort Racing driver had used part of the pit lane entry to make a pass and subsequently relegated him to 28th.
Thomas Preining claimed the victory from Schumacher and Vips.
Despite the penalty, Mawson has maintained his 46 point lead over Schumacher as the series heads to Zandvoort from August 19-21
