Audi is set to run two of its R18 e-tron quattro cars in Le Mans specification at Spa this weekend.
Motorsport.com understands that the most likely of the German manufacturers entries to race with the low-drag look that was seen at Monza last week will be the season entered No.7 of Andre Lotterer/Benoit Treluyer/Marcel Fassler and the No.8 car of Lucas Di Grassi/Oliver Jarvis and Loic Duval.
The third entered Audi R18 e-tron quattro of Marco Bonanomi/Filipe Albuquerque and new LMP recruit Rene Rast is believed to be running a version similar to that seen at Silverstone earlier this month.
Audi has remained tight lipped on the specifics of its Le Mans spec car but it is believed that the major differences are centered on the front wing elements , brake intakes and rear deck parts of the design.
Audi is set to reveal the cars officially later today at Spa.
