Nick Heidfeld was unimpressed with Lotus Renault GP teammate Vitaly Petrov after the duo made contact during the Turkish Grand Prix.

Heidfeld's and Petrov's cars touched after going side by side in the series of corners before the start/finish straight as the duo battled for position. The German felt Petrov had pushed him wide, and he made hand gestures to his teammate after the move.

"Yeah, that's not nice. It shouldn't happen," Heidfeld said. "He just pushed me wide and we made contact. It's not a safe thing to do."

Heidfeld went on to finish in seventh position, right in front of the Russian driver. The German said he was happy with his speed during the race, but not with the result itself.

"Not totally happy with the race. I'm happy with the pace, which was good, but I was in traffic most of the time and if I had a bit more free space I could easily have got a better result, but at least we have the race pace. I just have to find out why it didn't work out yesterday in qualifying."
