Officially unveiled in January of this year, the Audi RS7 is set to go on sale in the U.S. this fall. Accordingly, Audi has released pricing -- which starts at $104,900 for the high-performance sedan -- and a new campaign video showing off the vehicle's sleek contours. Billed as the most powerful RS model ever offered in the U.S., the RS7 is fitted with a twin-turbo 4.0 TFSI V8 engine -- good for 560 horsepower and 516 lb-ft of torque -- mated to an eight-speed Tiptronic automatic transmission and combined with Audi quattro all-wheel drive. The result is an impressive 0 - 60 mph launch time of just 3.7 seconds. Check out the RS7 in action below.
