Ferrari, Williams, BMW, and Mercedes are all tipped to be running a McLaren-style 'F-duct' system throughout Friday practice in Chinese GP.The track plan features a very extensive straight and Felipe Massa said he thinks the back wing-stalling system will be an important advantage this weekend. Sauber has been testing a system in practice sessions since Australia but has not raced it, awaiting now.
Our plan is to have it on the car from Friday to Sunday, Sauber's Pedro de la Rosa confirmed.
The Williams hinted on Thursday that a "rear wing upgrade" is one of the growths on the FW32 car in China. Auto Motor und Sport said the equipment will be up and running on Friday but driver Nico Hulkenberg would not confirm that it will still be on the car on Saturday and Sunday.
The system works very much like it does on the McLaren, said the young German. We will see how it goes tomorrow (Friday) and then see.
It is statements that Ferrari will as well have an F-duct working in Friday practice, as will Mercedes; amid rumors it adds up to 6mph to a car's top speed on the Shanghai straight.
In the wind tunnel and in the simulation, our system works, said Mercedes team Principal Ross Brawn. If Friday's practice confirms these results, then we will use it in the races.
But, Alonso exposed it was not Ferrari's main worry this weekend. I know that we keep developing the car, but it's not maybe the first priority for us, that system," he said. "We keep working on our philosophies. There is an important step here to improve the car, and I know that there is more coming in the next races. I'm not specifically worried only about that system.
