Formula 1 governing body FIA confirmed that Red Bull Racing’s engine mapping is legal following issues were raised by competitor Mercedes GP.
Recently Red Bull and Lotus call for explanation on the subject of the Mercedes GP’s new F-duct rear wing, and they are says new concept will help straight-line speed increase, its break the rules that prevents driver activated aerodynamic devices.
Discussions among the FIA and all the teams involved have taken place throughout Thursday in the Sepang paddock, but the governing body has not changed its stance on the matter. And FIA declared Mercedes DRS F-duct is legal.
FIA race director Charlie Whiting told Autosport about Mercedes DRS F-duct: “It is completely passive. There are no moving parts in it; it doesn’t interact with any suspension. No steering, nothing. Therefore I cannot see a rule that prohibits it.”
In 2012 teams are only legalized to cut up four cylinders off-throttle through the corners, but, Mercedes – based on audio analysis – believed Red Bull could be cutting extra. Mercedes raised their concerns with the FIA, who reportedly declared that there is nothing illegal about Red Bull’s engine mapping.
And McLaren team boss Martin Whitmarsh who gives explanation the situation, telling grandprix.com: “Mercedes has presented us with some audio analysis. It’s quite complex but the upshot is, they say it shows that Red Bull are cutting more than four cylinders, which you are not allowed to do.
“Actually, the cut pattern is not determined, so you can cut as many cylinders in whatever order you like. We’ve got the data and we can see quite clearly that there are four cylinders being injected, four cylinders firing and they are timed at the right time, so there’s every reason to suppose that there’s combustion going on.
“Moreover, the throttle opening at that point is not any more than it is normally, so if they are doing anything funny they are not opening the throttle any more, so it negates the arguments a lot. As far as we are concerned it’s entirely legal because they are not cutting more than four cylinders, which is what the contention is.”
