Sebastian Vettel Using ‘Secret’ Exhaust-Blown Key

Published

on

Vettel-retro2-suttonItalian magazine Autosprint reported that – Since Vettel has trimmed 2.5 seconds per lap to all its rivals in Singapore in the middle stages of GP , the question is legitimate : but how? An account are the great driving talent of three-time world champion and the goodness of its aerodynamic RB9 , but an account is a huge gap so the race pace , especially considering that in qualifying was just 1 tenth faster than the Mercedes .

Thousand hypotheses were made , including the existence of a traction control (moreover FORBIDDEN ) on RB9 . Well, in the current issue Autosprint tries to unravel the secret of the provision of Vettel : we rely on confidential information in our possession and our direct observation of the German action in Singapore. Our hypothesis is also supported by an exclusive video that we propose to follow when you hear the engine of RB9 ” ratare ” abnormally and significant mid-corner .

In our opinion the particular sound of the engine does not prove the existence of a traction control , because the noise occurs in the middle of the curve, transient and not in full acceleration . Vice versa is due to the use of a particular mapping that manages the flow of exhaust gases by using them in a way similar to what happened with the speakers ” blown ” of 2011 . The exhaust gases have an average speed estimated at about 400 km / h , so the effect feels more about the slow corners of Singapore on the straights of Monza .

The full explanation on Article in the number of Autosprint on newsstands Tuesday, October 1. But for now listen to the movie here to follow very carefully raising the volume of your computer or tablet. Be careful because Vettel is the first to pass : hear how it sounds different – but only at the middle of the curve – the noise of his RB9 compared to all the other cars that follow after a few moments .
