The facelifted S-Class will feature notable changes under the hood. The S450 and S500 models will be equipped with the updated inline-six engine, known as the “M256 Evo,” which delivers 443 pound-feet of torque, an increase of 30 lb-ft from the previous model. An overboost function will temporarily raise torque to 472 lb-ft. The S580 variant will adopt the new “M177 Evo” flat-plane-crank V8 engine, producing 530 horsepower and 553 lb-ft of torque, marking gains of 34 hp and 37 lb-ft over its predecessor. This engine will also be the first to utilize a flat-plane crankshaft in a Mercedes luxury sedan, enhancing performance and efficiency.

Additionally, the S-Class will offer a plug-in hybrid variant, the S580e, combining the revised six-cylinder engine with an electric motor for a total output increase of 74 hp and an estimated electric range of over 62 miles. All gasoline-powered models will feature particulate filters and pressurized fuel tanks, while diesel options will comply with stricter emissions regulations through the new “OM 656 Evo” engine.

The S-Class facelift will also introduce a refined air suspension system that anticipates road irregularities using cloud-based data from other Mercedes vehicles. This system pre-adjusts damping to enhance ride comfort. Furthermore, the standard rear-wheel steering will now include a 4.5-degree setup, with an optional 10-degree system available to reduce the turning circle significantly.

Despite the extensive updates, the current S-Class has faced criticism for its interior design and reliance on screens. Observers note that while the facelift aims to modernize the vehicle, it may not address these concerns, as Mercedes is expected to maintain its contemporary dashboard layout. The S-Class will continue to compete in a shrinking luxury sedan market, facing rivals such as the BMW 7 Series and the Genesis G90, while the Lexus LS is being phased out.
