Audi's new A3 Clubsport Quattro Concept is an RS3 in a different name. They are displaying it at this week's Wörthersee Meeting in Austria. The car is fitted with a 2.5 liter TFSI with 518hp and 600Nm linked to a 7-Speed S Tronic dual-clutch transmission and quattro all-wheel drive system.

"The Audi A3 clubsport quattro concept shows our car and tuning fans at the Wörthersee just how much sporty potential there is in the A3 family and in our top‑of‑the‑line engines such as the 2.5 TFSI," commented Audi development boss Ulrich Hackenberg. "We have pushed the limits in every respect with this show car: power, dynamics, sound, design."

As for the air brake, according to Audi, at 250 km/h (155.3 mph), "the air brake reduces the stopping distance by around twelve meters (39.4 ft), in part because the ESC can allocate more braking power to the rear axle thanks to the increased downforce".
