Even if soon implemented, the new diffuser will not have the immediate effect of equaling the level of performance showed by Brawn GP, Williams or Toyota, argued the 2-time world champion. Renault will not only be forced to design a new rear diffuser, but also revise the entire aerodynamic package of the car.
Putting all these things together will nonetheless necessitate time, something that neither Renault, nor the other 6 teams entering the diffuser race seem to have at the moment. Under the circumstances, Alonso argued the Brawns will still be the drivers to beat in the upcoming races.
“From a driver's point of view, we do not understand, we are not technical people so we are not very sure about what the rules say, but it is true that there are some cars that are much quicker than us, Brawn, Toyota and Williams,” said Alonso at Shanghai, ahead of the upcoming Chinese Grand Prix.
“And it will take time to recover and close that gap and be as quick as them, because I don't think it is a diffuser thing or a magic part in the car that you put on and you go straight away quick. You need to re-design the car a little bit, starting from the front wing.”
“The air has to go to the rear-end of the car in a different way. So there is still some months I think to work, to spend money, to develop the car to be as quick as them. It is not only the diffuser, it is just a different philosophy of designing the car.”
