Belgian Audi Club Team WRT has been very busy testing their Audi R8 LMS ultra cars in recent weeks and they added to that list by testing at Spa-Francorchamps on Tuesday.
They have been at a number of European circuits recently, including:
Zolder, Silverstone, Monza, Nogaro and the official test days at the
Nürburgring (VLN) and Paul Ricard (Blancpain GT Series).
