The legendary rally car takes a gorgeously futuristic twist. The Audi TT Ultra Quattro Concept has shed just under 95 lbs and sports a turbocharged 2-liter 4-cylinder engine with 310 hp and 295 lb-ft of torque. It will get to 60 mph in 4.2 seconds and plateau at 173. Inside, there are cool carbon fiber bucket seats and trim, all specially made to help shed weight and increase speed and performance. Yet another icon in the making.
