Audi driver Mike Rockenfeller headed four manufacturer colleagues in the first free practice session of the DTM weekend at the Norisring.

The German driver lapped the circuit in 46.527 and was 0.130 seconds faster than French Audi driver Loic Duval in second place.

Team Rosberg driver René Rast claimed third position ahead of Nico Müller, both within three tenths of a second from the top time.

Philipp Eng was the fastest non-Audi driver for BMW, claiming position five with the time 47.046. The Austrian driver was followed by Robin Frijns who caused one of the few incidents during the session.

The Dutch driver spun in the final corner and stalled in a dangerous position at the exit of the corner. All drivers managed to avoid him and he was able to return to the pits shortly after.

Bruno Spengler of BMW Team RMG claimed the seventh fastest time ahead of Audi driver Jamie Green in eighth. Daniel Juncadella was fastest of the Aston Martin drivers in ninth position, nine tenths of a second from the top time.

The second free practice session starts at 16:15 CEST.
