Under the hood of the 2024 S63 E Performance lies a twin-turbocharged 4.0-liter V8 engine paired with a 13.1-kWh lithium-ion battery and a rear-mounted electric motor. Together, this setup delivers an astounding 791 horsepower and 1,430 Nm of torque. The hybrid system enables the S63 to sprint from 0 to 100 km/h in just 3.2 seconds, with an electronically limited top speed of 250 km/h.

The powertrain incorporates a nine-speed automatic transmission for the V8 engine and a two-speed automatic gearbox for the electric motor, optimizing performance across different speeds. Drivers can also choose from various modes, including a fully electric mode with a range of up to 26 kilometers. While this PHEV setup adds impressive straight-line performance, some reviewers have noted that the system can feel clunky at low speeds, particularly during transitions between electric and gas power.

The 2024 S63 E Performance retains the elegance synonymous with the S-Class while incorporating sporty AMG elements. The exterior features the iconic Panamericana grille, sleek LED headlights, and 21-inch forged alloy wheels, with optional upgrades for those seeking an even bolder aesthetic. Finished in luxurious paint options like Manufaktur Kalahari Gold, the S63 exudes sophistication and presence.

Inside, the cabin is a sanctuary of luxury and advanced technology. High-quality materials, such as Nappa leather and carbon fiber trim, adorn the interior, while the 12.8-inch infotainment touchscreen and 12.3-inch digital instrument cluster dominate the dashboard. The MBUX infotainment system is user-friendly, though some may find the touch-sensitive controls less intuitive compared to traditional buttons.

Passengers will appreciate the air suspension, which smooths out imperfections on the road, ensuring maximum comfort even in Sport+ mode. Rear-axle steering adds agility, making the S63 surprisingly adept in corners for its 2,600-kilogram curb weight.

One of the most impressive features is the advanced driver assistance suite. This includes adaptive cruise control, lane-keeping assist, blind-spot monitoring, and an augmented reality head-up display that projects crucial information, such as speed and navigation, directly onto the windshield. The 360-degree camera system further enhances safety, making parking and tight maneuvers effortless for a car of this size.

For audiophiles, the optional Burmester 4D surround sound system, priced at nearly $7,000, delivers an immersive listening experience, complete with in-seat resonance effects for a truly unique touch.
