The 2019 Mercedes-Benz S-Class is available in four models; S 450, S 560, AMG S 63 and AMG S 65. Each model is set apart by their engine, with the AMG models driving performance to the upper limits. The S 450 is powered by a turbocharged 3.0L V6 engine making 362 horsepower, while the S 560 employs a turbocharged 4.0L V8 producing 463 horsepower.

Performance and handling in the S-Class is second to none. Multimode drive selection allows drivers to select from four different modes to change throttle response, shifting and steering control as desired. The expected comfortable ride is achieved through Mercedes' AIRMATIC suspension and adaptive dampening system.

The AMG S63 gets a special AMG Adaptive Sports Suspension that's tuned to make the most of the all-wheel drive system's capability and this car's more performance-oriented setup. The AMG S65 also adds a sport version of Magic Body Control, but it also comes with a speed-sensitive sports steering with multiple settings and a distinct steering-wheel design. Special 20-inch AMG forged-alloy wheels are included in this model, along with a sport exhaust system with twin tailpipes and an available ceramic high-performance composite braking system.
