US-Spec 2015 Mercedes S63 AMG Coupe 577 HP

 The American version of the second most excessive Mercedes comes with all-wheel drive instead of just RWD, 577 horsepower, 664 lb-ft of torque and uncomfortable road head as standard.

So, Europeans get an eight extra horsepower, but the most interesting thing about the "smaller" AMG Coupe remains that while the V12-powered brother sends all its 621 horsepower and 738 pound-feet of torque to the rear wheels, the S63 comes with 4MATIC, which directs 33% of the Kraft to the front. The rest is the same the S65 AMG, honestly.
