Sound job : The chassis has reportedly been modified to accommodate the extra power, gaining upgraded suspension, steering and braking systems. This particular test car is thought to be the top end RS version of the new R8. Tell-tale signs are the exhaust pipe and diffusers, which are the same as those fitted to Audi's other V10 models, as well as the new grille design. Onlookers even claim the test car had the sound of a V10 and not a V8.
