Spy photographers just spotted Audis club sport racer the Audi R8 CS. With its big fixed rear wing, big round exhaust pipes, bigger diffuser and re-designed rear bumper (air outlets on the sides) it really sticks out compared to a “normal” R8 V10. Front bumper is also different with its small wings on both sides. Except for a power boost, we expect it to have lost some weight as well to make the CS package complete.
