Mercedes drivers David Coulthard and Renger van der Zande could be excluded from the Valencia DTM round after their cars were found to be illegal after qualifying.
Both men, who race old-spec C-class machines, were found to have rear overhangs that were 'not in compliance with the DTM technical regulations.'
Stewards initially disqualified both drivers from qualifying, meaning that the pair were sent to the back of the grid from their third and fourth places. However, both the Mucke and Persson Mercedes teams have signaled their intention to protest the decision, meaning that both will start the race from their original grid positions and race under appeal.
Should the teams lose their appeals to the Spanish motorsport authority, or choose not to file them, both drivers are likely to be disqualified from the race as well.
