Audi fans in the U.S. will be happy to know that the Audi TT RS will arrive on American shores by the end of next summer.  The early word from Audi is that the U.S.-spec car is capable of sprinting to 62mph in 4.6 seconds.

However, it may actually be a bit faster.  The car will be tuned to deliver 360 horsepower (268 kW), 20 hp (15 kW) more than the European car.  The 2.5-liter TFSI is also capable of dishing out up to 332 ft-lb of torque.  It's top speed was not revealed.

Audi built interest into a potential American release of the car through an online marketing effort.  The campaign led to 11,500 Facebook and Twitter users requesting that the automaker bring the car Stateside.

US pricing for the Audi TT RS has not been determined, according to a press release.
