The V223 S-Class, launched in 2020, represents the seventh generation of Mercedes-Benz’s iconic luxury sedan. The AMG S 63 E PERFORMANCE builds upon this foundation, adding a high-performance plug-in hybrid powertrain. It’s built on the M117 engine family, and utilizes the 4MATIC+ all-wheel-drive system. The long-wheelbase configuration (V223) provides increased rear passenger space, further enhancing the vehicle’s luxury appeal. This model is aimed at buyers who demand the ultimate in performance, technology, and refinement, and represents a significant step forward in hybrid performance for the S-Class lineage.
Powertrain & Engine Architecture
At the heart of the AMG S 63 E PERFORMANCE lies a 4.0-liter twin-turbocharged V8 engine (M177) producing 612 horsepower and 900 Nm (663.81 lb-ft) of torque. This engine features a “hot-vee” configuration, with the turbochargers positioned within the V of the engine for improved responsiveness. Direct fuel injection and a sophisticated engine management system optimize combustion efficiency. Supplementing the V8 is a 190-horsepower electric motor integrated into the rear axle. This electric motor draws power from a 13.1 kWh lithium-ion battery pack located under the trunk floor. The AMG SPEEDSHIFT MCT 9G transmission, a nine-speed automatic, is specifically tuned for performance and features a wet clutch pack instead of a traditional torque converter, enabling faster and more direct gear changes. The hybrid system allows for all-electric driving for up to 33 km (20.51 miles) according to WLTP standards.
Driving Characteristics
The combination of the V8 engine and electric motor results in a total system output of 802 horsepower and a staggering 1430 Nm (1054.71 lb-ft) of torque. This translates to blistering acceleration, with a 0-60 mph time of just 3.1 seconds. The electric motor provides instant torque, filling in any gaps in the V8’s power delivery and enhancing responsiveness. The AMG SPEEDSHIFT MCT 9G transmission offers quick and precise shifts, while the 4MATIC+ all-wheel-drive system provides exceptional traction in all conditions. Compared to non-hybrid S 63 models, the E PERFORMANCE variant offers a unique driving experience, blending the raw power of the V8 with the smoothness and efficiency of electric propulsion. The weight of the battery pack does add some mass, but the increased power more than compensates for this.
Equipment & Trim Levels
The AMG S 63 E PERFORMANCE comes standard with a comprehensive suite of luxury and technology features. Interior appointments include exclusive AMG Nappa leather upholstery, carbon fiber trim, and a sport steering wheel. Standard technology includes the MBUX infotainment system with a large touchscreen display, a digital instrument cluster, and a head-up display. Available options include massaging seats, a premium Burmester sound system, and advanced driver-assistance systems such as adaptive cruise control and lane-keeping assist. The long-wheelbase configuration provides ample rear legroom, making it ideal for chauffeured transport.
Chassis & Braking
The chassis of the AMG S 63 E PERFORMANCE features an AIRMATIC air suspension system with adaptive damping, providing a comfortable ride while maintaining precise handling. The suspension is tuned specifically for the increased weight of the hybrid system. Large ventilated disc brakes with AMG-branded calipers provide powerful stopping performance. The braking system is further enhanced by ABS, electronic brake-force distribution, and brake assist. Active rear-wheel steering is also standard, improving agility and maneuverability, especially at lower speeds.
Market Reception & Comparison
The AMG S 63 E PERFORMANCE has been widely praised by automotive critics for its exceptional performance, luxurious interior, and advanced technology. It is often compared to other high-performance luxury sedans, such as the Porsche Panamera Turbo S E-Hybrid and the BMW 760i xDrive. Compared to the standard S 63, the E PERFORMANCE variant offers improved fuel economy and the ability to drive in all-electric mode. However, it also carries a higher price tag. The hybrid system adds complexity, potentially increasing maintenance costs over the long term.
Legacy
The AMG S 63 E PERFORMANCE represents a significant step forward in the evolution of the S-Class. It demonstrates Mercedes-Benz’s commitment to both performance and sustainability. While long-term reliability data is still emerging, the combination of a proven V8 engine and a well-engineered hybrid system suggests that this powertrain should be durable and reliable. As the automotive industry shifts towards electrification, the S 63 E PERFORMANCE is likely to be remembered as a pivotal model that bridged the gap between traditional luxury and cutting-edge hybrid technology. Its position in the used car market will likely remain strong due to its exclusivity, performance, and advanced features.
