Even the stately S-Class hasn’t been able to escape fettling by the wizards at AMG, and the result is the fastest-accelerating model in the range. The S63 is powered by a 4.0-liter bi-turbo V8 engine that produces 603 hp and 664 lb-ft of torque. A nine-speed automatic transmission, 4Matic+ all-wheel-drive, and an adaptive suspension are standard.
The handsome S63 gets 20-inch AMG wheels, quad exhaust outlets, AMG body styling with gloss black trim, all-LED lighting, and a panoramic roof. A carbon fiber exterior package is optional for an even racier look. Inside the cabin, Mercedes has fitted a full house of comfort and safety features. The front seats feature massaging, heating, and 12-way power adjustment, while seat ventilation is available. Also standard are dual 12.3-inch digital screens, a 13-speaker Burmester surround-sound system, a surround-view camera, navigation, Apple CarPlay, Android Auto, power sun blinds for the rear window and rear-side windows, and dual-zone automatic climate control. Extensive ambient lighting, Nappa leather upholstery, and a range of wood trims envelope the driver and passengers in a truly opulent environment. There are also several upgrades for the rear seats, including a four-seater option with two supremely comfortable rear seats replacing the standard rear bench.
