BMW DTM driver Farfus slams 'dangerous' Rockenfeller move at Moscow

Farfus had been attacking Rockenfeller for second place on the second lap of the race, using DRS and moving to the inside approaching the final corner.

But as Rockenfeller moved to defend the inside line, the pair made contact, Farfus just keeping control and nudging ahead as they crossed the start/finish line before Rockenfeller reclaimed the place.

Farfus then dropped back with a front-right puncture and was forced to pit at the end of the third lap, effectively ending his race.

Rockenfeller, who was racing with a foot injury picked up in a major crash with Gary Paffett's Mercedes at the Norisring, escaped with only a warning from the stewards, and went on to finish second behind Audi squadmate Rene Rast.

In the aftermath, Farfus and Rockenfeller could be seen arguing at length during post-race media interviews.

The German told Farfus he felt the defensive move was "early enough" and that he was hoping the Brazilian would've backed out of the overtaking attempt, while Farfus insisted he had no opportunity to lift and avoid the accident.

"The move from Rocky was unacceptable," Farfus told Autosport.

"The level we race here, it is extremely dangerous. You cannot overreact to someone to your side at 260 [km/h] and push the guy off-track.

"It could have been a super-bad crash. I was on the DRS on the inside and he pushed me off track, [for him] to get only a warning from it is a bit optimistic.

"If you see a guy coming with DRS, you have to block. But you can't block when the guy is by your side.

"We saw an extremely big crash where he was involved at the Norisring. You cannot take these risks."

BMW motorsport boss Jens Marquardt took a similarly dim view of Rockenfeller's driving.

"For me this manoeuvre was for me on the edge of sporting [behaviour], it was completely unnecessary, and for me stupid and dangerous as well," he told Autosport.

Asked if Rockenfeller's should have been given a penalty for the move, Marquardt replied: "Absolutely, I don't think a warning was the right thing, especially when you destroy somebody's race and you then end up on the podium."

Speaking in the post-race press conference Rockenfeller said he felt Farfus had simply driven into him once he had made his move to defend his line, but added he needed to see a replay to be certain.

"First I need to see a little bit the video, but in my opinion he tried to attack, I wanted to close [the door], I changed once my line, and he drove into my car," said the German.

"That's how I felt. But I need to see the pictures, maybe I'm completely wrong."
