Audi only imported 850 of these little known powerhouse beasts to America. Powered by a Twin Turbo 4.2L FSI v8 it has the balls to back up the RS badge and stomp many drivers thinking its just another A6. It isn't suspecting untill you notice the flared wheel wells and 8 piston brembo calipers paired up with two intercooler air inlets in the front bumper. If your unfamiliar with the RS 6, the growl of the exhaust and spool of turbos will let you know its far from your average Audi.
