not had to wait long to get the first, usual skirmishes in the paddock of Formula 1 Circus. The cause of friction between committed by the team yesterday in Valencia for the first three days of testing season, is the exhaust system adopted by Lotus Renault. Although several rival teams of engineers claim that it was well known for a while ', this solution is the most controversial among what we have seen so far on the 2011 car, and drove a certain sensation. This solution determines that the exhaust pipes, instead of terminating at the rear, fold the sides towards the front passing through, resulting in proximity of the air intakes on the side pods, the jet of gas is then pushed back again and out of a "elbow". Consequently, these streams pass under the bottom plate, with a speed di circa 400 km/h, generando un incremento dell’effetto suolo e un maggior carico aerodinamico.
Quanto siano efficaci ancora non è dato saperlo, anche se i tempi fatti registrare ieri da Petrov, e il lungo lavoro che alla Renault hanno fatto ai box, piuttosto che in pista, non sono una garanzia d'efficacia. Di contro, però, molti hanno ravvisato un potenziale pericolo, a causa della alte temperature dei gas di scarico, che con questo sistema passano molto vicino all'abitacolo.
Adrian Newey prende la questione con filosofia: “ C'è sempre un po' di nervosismo ad inizio stagione, perchè le modifiche che possiamo fare sono poche. E' difficile farsi venire un colpo di genius, but if our opponents will improve, we will respond .
A diatribe reminiscent in some ways, than last year on the F-duct: the McLaren system to convey flows to the rear, the other team tried to copy only partially successful, because the device was inserted into the frame which, once approved could not be changed in the season started. Newey is shown here too pragmatic, " What happened last year does not recur, until the season starts, we will have time to respond to other solutions, if necessary .
Despite the controversy, some teams may turn to this solution, the first would be the McLaren. According to German magazine Auto Motor und Sport ", the MP4-26, which will be presented Friday, would be equipped with a system similar to that seen on the R31.
Likewise, you show possible the head of Mercedes, Ross Brawn: " I think that Renault has taken a right direction with these discharges, we're working on something similar .
Well, we're just the first act of a battle that will continue throughout the course of testing pre-season, given that most teams will present the final configuration of the car just behind the opening round, in Bahrain.
