"We are very happy about this result," confirms Theissen. "On the one hand, it was just another fourth place. But it was also a very special fourth place because it was the first time we were able to match the speed of the top teams. "The fact that Nick Heidfeld managed to overtake world champion Fernando Alonso on the track provides Theissen with a further good reason for optimism. "Nick was the only driver out of the top six who overtook competitively on the track. That is why it was very special and our strongest performance so far."He also says the top teams are looking over their shoulders with a concern for BMW.
