While BMW Sauber was able to celebrate Robert Kubica's first points of a tough 20098 Formula One season, the Pole's team-mate was left to rue early race problems that he claims denied the team two cars in the top eight.
The Turkish Grand Prix saw the debut of BMW Sauber's take on the double-deck diffuser that caused so much consternation when it appeared on the Brawn, Williams and Toyota at the start of the year and, while it did not appear to have too great an effect on the F1.09's performance as Kubica and Heidfeld occupied 16th and 17th spots on day one, the pair gradually came more into contention as the weekend wore on.
Kubica duly made it in to the final phase of qualifying, while Heidfeld only missed out at the death in Q2, although the pair still lined up next to each other, in tenth and eleventh places respectively. From there, their races diverged widely, as Kubica made immediate gains that left him in position to open his account, and Heidfeld suffered the gremlins that caused him to miss out.
"It is good to finally score points, and I think I raced well," Kubica said of his run to seventh, "My pace was good and I made no mistakes, but the race was very hard, as nearly all the time I had someone very close behind me, and the smallest mistake would have cost a position. It was very hard to keep up the pace, but finishing seventh was a clear step forward. We just have to keep up the speed of development."
Heidfeld, meanwhile, finished in the same position as he started, but firmly believes that he could have joined Kubica in the points had it not been for a poor start.
"I lost all my chances in the beginning when I had a problem with the car," the German confirmed, "As early as the formation lap, I realised that it pulled to one side and the front left tyre had no grip at all. It stood still further when I tapped the brakes softly.
"The start itself was okay as I was ninth, but then I more or less went straight on in the first corners and quite a few cars went by me. It was better in the second and third stints, but it was way too late for points.
"My strategy was to start the race with a lot of fuel and drive a very long first stint. That should have helped me to work my way through the field a bit. I was really hoping to pick up some points - particularly as our car, with its new aerodynamic package and double diffuser, was good enough to make it [into the top eight].
"Nevertheless, it is positive that the car has generally improved, and that, again, we are able to score on our own merits. I'm looking forward to Silverstone."
