McLaren rule out changing Montoya's engine

Montoya claimed his engine was lacking power compared to teammate Kimi Raikkonen's, saying he was seven km/h slower on the main straight with the same set-up as the Finn.

"Unless we want to finish about 10th or 12th then we should think about changing it (the engine) to be honest. But it is not my call," Montoya said.

Dennis, however, said the engines are exactly the same and ruled out changing Montoya's unit.

"The engines are absolutely fine," said Dennis. "There's no difference between the engines and there is a difference between gearing.

"When you run at lower revs in order to protect the engine, you end up with less than optimised mapping and that does make the engine a little uncomfortable to drive.

"When you move into the area of preparing for racing and qualifying, it's a different area where we have to look at the engines, but they're exactly the same."
