Even with the new Formula One engine regulations, the BMW P84 engine is more than capable of being raced on the limit even in the race.
Thanks to the innovative television coverage which shows the rev counters on the cars this year, the engine of the WilliamsF1 BMW FW26 is still a number one talking point when it comes to discussing the most powerful engine in Formula One. "The rpm measurements shown on TV screens are realistic," confirmed BMW Motorsport Director, Mario Theissen.
According to Theissen, the development of this season's Formula One engine was a huge challenge because an engine that could be raced at its limit during the race, and not merely for one 'flying lap' during qualifying, was required.
"Our main aim was to produce an engine that would be capable of spending the whole race on the limit," explained the German, "That's more important to us than looking for the last two or three bhp. We are now in a position whereby the qualifying rpm can be used during the whole race, and in top gear."
Despite what one might think, this is not something to be taken for granted, even in the hi-tech world of Formula One. "It is actually very unusual," admitted Theissen, "Normally, the top gear would be set 500 to 1000 revs longer, because you would usually race more than five seconds in top gear. You also need a reserve of 200 to 300 revs for slipstreaming so that during an overtaking manoeuvre you're not restricted by the rev limiter."
With the 'Circuit de Catalunya' having a full power ratio of about 60 percent, the circuit is one which will see the BMW WilliamsF1 Team benefit from its powerful BMW P84 engine.
