Notes
  1. Both cars entered as Mercedes-AMG Team Zakspeed from Rounds 1 to 6, but at Round 7 both cars entered as Team Zakspeed. This happened after Mercedes-AMG terminated its contract with the team, following the double disqualifications at the Sachsenring.
  2. Marvin Kirchhöfer only drove in Race 1 at the Nürburgring, while Maximilian Buhk only drove in Race 2. They both shared the car with Indy Dontje.
