There are many choices in big, powerful, and indulgent today, but few that can outdo this AMG version of Mercedes’ two-door S-class on all three criteria. The S63 AMG coupe shares a mechanical package with the similarly named sedan, principally its 5.5-liter twin-turbocharged V-8. With 577 horsepower and 664 lb-ft of torque at the behest of its sharp throttle, this is about as close to a jet engine as you’ll find in a street-legal automobile. The S63 is just gorgeous inside and out. Not flashy (well OK, maybe a little flashy), but curvy and beautiful. Dignified. It wafts along in town like the luxury car it is, but tromp on the gas pedal and whoa baby!! Benz quotes a sub-4.0 second zero-to-60 time. The seven-speed AMG Speedshift MCT transmission (with a wet starting clutch instead of a torque converter) and engine stop-start tech also carry over from the sedan, as does a performance-tuned 4MATIC four-wheel-drive system that sends 67 percent of the torque to the rear axle. The coupe rides 0.4 inch lower than the sedan, and the front wheels have more negative camber for improved cornering. The coupe drives similarly to the sedan, but better. The two-door’s 115.9-inch wheelbase is 8.7 inches shorter, and the difference in maneuverability and cornering is profound. Steering has been improved, with a bit more feedback now filtering through a heavier helm.
