Sep.11 (GMM) The Spa-Monza double header may now be over, but the sound of Formula One engines will soar again on Tuesday.
Ferrari, Mercedes and Force India are set to begin their three days of 'young driver' testing at the former French Grand Prix venue Magny Cours.
Jules Bianchi, Luiz Razia and Rodolfo Gonzalez will be driving for Force India, Sam Bird for Mercedes, and Frenchman Bianchi and Davide Rigon for Ferrari.
Ferrari has "a lot of new things" in the pipeline for the forthcoming Singapore Grand Prix.
"One of the priorities of the (Magny Cours) test," said team boss Stefano Domenicali, "will be to fine-tune the correlation between the simulator and the track".
According to Germany's Auto Motor und Sport, Mercedes is also preparing a major development package and a "completely new rear" for its struggling W03 car.
"It (the new package) includes the so-called Coanda exhaust and new side pods," said the specialist publication.
The report added that the new package is the first real fruits of Mercedes' recent wind tunnel upgrade from 50 to 60 per cent.
