Audi has confirmed that two of its three cars racing at this weekend’s 6 Hours of Spa will be running with a low downforce aerodynamic configuration in preparation for the 24 Hours of Le Mans in June.
The new package has been fitted to the no. 7 and no. 8 cars for the race at the Circuit de Spa-Francorchamps in Belgium, which acts as the second round of the 2015 FIA World Endurance Championship.
Audi heads to Le Mans in June seeking a sixth consecutive victory at the Circuit de la Sarthe, and hopes to put itself in the best possible position by testing these new aero kits at Spa.
“Because downforce at Le Mans is not as important as it is at other tracks, we developed other solutions and new body shapes,” Audi head of aerodynamics Jan Monchaux said.
“In this way, we reduce the drag. All the turning vanes, wings and similar elements are no longer mounted so steeply in the airflow; the curvature of the wing profile is less.
“The cooling system’s requirements are different. We were able to re-evaluate and adapt the flow across the cooler, because at Le Mans less air mass flow is necessary due to the higher speeds.”
Audi’s third car will also make an appearance at Spa ahead of Le Mans, but will be running with the higher downforce aerodynamic package that was used by the German marque en route to victory at Silverstone three weeks ago.
The no. 9 Audi will be piloted by Marco Bonanomi, Rene Rast and Filipe Alberquerque.
