Often it had been beleived that BMW has the most powerful engine in F1 and they certainly prooved that by getting good results in qualifying and the most recent is at Monza.
I think that the BMW engine can only rev to the max for a couple of laps only.
Why? ...because usually on raceday when any of the Williams try to keep pace with the Ferraris, usually the engine will blow up.
At Monza recently, while Ralf was ahead and Montoya tried to hold Rubens behind him so that Ralf would have number of secs lead advantage. I bet they boosted the rev limiter and ending up Ralf blewing his engine at a later stage.
They have the power but not reliability..anybody think otherwise?
