Spain Sunday quotes: BMW

"I had quite a good, consistent race, although I had some problems with tyre degradation in the second stint when I was behind Alonso and Coulthard was closing the gap, but everything was under control. In the end, after the second pitstop, I tried to push and make the gap to Coulthard bigger. Now we have to continue working in this direction."

Nick Heidfeld - DNF: "In the end it was most likely a gearbox problem that stopped me, but unfortunately my race was over much earlier after the problem during my first pitstop. For some reason the front right wheel was loose, we have to look at it how this happened. For the first 24 laps until this stop it looked superb for me.

"I drove a long first stint and my second stint would also have been a long one. On top of this Alonso was not very quick on the harder tyres in his second stint. I believe I had the chance to finish on the podium today."

Mario Theissen (BMW Motorsport Director): "We view the result with mixed emotions. Eight cars retiring was a lot today, and sadly we were among them ' most likely it was a gearbox failure. But as disappointing as this is for us and for Nick, it was a positive result for Robert. He scored our fourth fourth place today, drove a very good race and our team is now established as the third strongest. At the end of the day the result is pleasing."

Willy Rampf (Technical Director): "After a race like this I have mixed feelings. Robert drove a strong race and deserved fourth place. Nick was also in a good position before his pit stop. We then had a problem fitting the front right wheel nut, had to bring Nick in one lap later and, as a result, his race was ruined. After 46 laps a technical failure forced him to retire. However, on the positive side we are pleased with five more championship points."
