Audi unveiled its new TT RS in both coupe and convertible body styles today at the Beijing Auto Show, featuring a five-cylinder engine good for 400 horsepower and 354 pound-feet of torque, channeled to all four wheels in typical Quattro fashion. The output allows the car to go from 0 to 62 miles per hour in 3.7 seconds. On the exterior front, the TT RS has aggressive good looks, thanks in large part to a fixed rear wing, larger wheels and a sharper front fascia. The standard rear taillights are LED units, but buyers can opt for OLED units with a 3D appearance. Overseas, the car launches in the fall; American buyers can expect a 2017 arrival.
