Although the Mercedes-AMG S 65 sits above the S 63 in both price and power output, it’s the S 63 that’s the ultimate performer within the S-Class range. With a 4.0-liter twin-turbo V8, the S 63 has a colossal 603 horsepower and 664 lb-ft at its disposal, enough for a 3.4-second run to 60 mph. A nine-speed multi-clutch transmission and 4matic all-wheel-drive are standard.
With 20-inch wheels, modified bumpers, and quad exhaust outlets, the S 63 looks like it means business before you even get behind the wheel. Once seated, there’s plenty to enjoy. The Nappa leather seats feature 12-way power adjustment in front, while those seated at the back have acres of legroom. Further luxury-car items include soft-close doors, 64-color ambient lighting, an electronic trunk closer, and power rear-window sunshades. Dual 12.3-inch screens take care of instrumentation and infotainment, and the sound system is a 13-speaker Burmester unit. For peace of mind motoring, the S 63’s comprehensive safety specification boasts Mercedes’ pre-safe system, rear cross-traffic alert, nine airbags, and blind-spot monitoring.
