The cd value of the new Audi R8 V10 performance quattro is 0.36; its frontal area is just 2.01 m2(21.6 sq ft). However, the decisive factor in the aerodynamics concept is the force that presses the vehicle onto the road and enables high cornering speeds: The Audi R8 Coupé V10 performance quattro achieves 140 kilograms (308.6 lb) of power output, 100 kilograms (220.5 lb) of which are achieved at the rear axle. Its blade, firmly mounted on the rear end, works together with the diffuser.

The underbody of the high-performance sports car, including the propeller shaft, is almost completely covered with smooth paneling. Two small diffusers in the front area send air through the wheel wells; this also helps to cool the brakes. Upstream of the rear axle, the paneling integrates what are known as NACA vents, which transport cooling air to the engine and S tronic. The wide diffuser beneath the rear end ensures that the accelerated air is reduced to ambient speed again without swirling too much. This suction effect enables a faster flow and thereby increases the power output.

The V10 draws its inlet air through openings in the vehicle rear and through two long connecting pieces that lead to the sideblades. The temperature in the engine compartment is regulated in multiple ways but mainly via the large opening in the rear end. In the front body, the cooling air flows optimized through enclosed channels – this solution also comes from motorsports.
