After wowing everyone with the S-Class Concept Coupe, Mercedes big grand tourer has revealed its production form and it looks like the former CL will definitely be stealing some attention away from Aston and Bentley. Scheduled to hit dealerships this fall, the new S-Class Coupe will launch stateside with an all-wheel-drive S550 model that will boast a 4.7L V8 biturbo that will produce 449 hp and 516 lb-ft of torque.
