This article provides a comprehensive examination of the Mercedes-AMG GT63 S E Performance, including its hybrid powertrain, performance, engineering, design, and what it represents for the future of AMG.
The AMG GT Lineage
The Mercedes-AMG GT four-door coupe was introduced in 2018. It was the third model in the AMG GT family, following the two-door coupe and the roadster. The four-door coupe combined the performance of a sports car with the practicality of a sedan.
The GT63 S, with its 630 horsepower V8, was the most powerful version of the car. The GT63 S E Performance builds on that foundation, adding an electric motor to the rear axle and a battery pack.
The E Performance Name
The E Performance name indicates Mercedes-AMG’s hybrid powertrain. The “E” stands for electric, and the “Performance” indicates that the hybrid system is designed for performance rather than efficiency. The system is derived from the technology used in the Mercedes-AMG Petronas Formula 1 team, which has used hybrid powertrains since 2014.
Powertrain: The Heart of the E Performance
The V8 Engine
The GT63 S E Performance is powered by a 4.0 liter twin-turbocharged V8 engine, designated the M177. This engine produces 630 horsepower at 5,500 to 6,500 rpm and 664 lb-ft of torque at 2,500 to 4,500 rpm. The redline is 7,000 rpm.
The engine features a hot-vee configuration, with the turbochargers mounted inside the V between the cylinder banks. This layout reduces lag and improves throttle response. The engine also features a dry-sump lubrication system, which allows it to withstand high g-forces.
The Electric Motor
The GT63 S E Performance features an electric motor mounted at the rear axle. The motor produces 201 horsepower and 236 lb-ft of torque. It is integrated into a two-speed transmission, which allows it to provide power across a wider range of speeds.
The electric motor draws power from a 6.1 kWh lithium-ion battery pack, mounted at the rear of the car. The battery is designed for power delivery rather than range, with a focus on providing the electric assistance needed for performance.
The Total Output
The combined output of the V8 engine and the electric motor is 831 horsepower and 1,033 lb-ft of torque. This makes the GT63 S E Performance the most powerful production Mercedes-AMG ever built.
Performance
Acceleration and Speed
The GT63 S E Performance accelerates from 0 to 60 miles per hour in 2.9 seconds. The 0 to 124 miles per hour sprint takes approximately 10.9 seconds. The quarter mile is completed in approximately 11.0 seconds at 130 miles per hour. Top speed is 196 miles per hour (316 kilometers per hour).
Electric Range
The 6.1 kWh battery provides an electric range of approximately 8 miles. The car can be driven in electric-only mode at low speeds, making it suitable for urban environments. The hybrid system also allows for silent operation when desired.
Weight and Balance
The GT63 S E Performance has a curb weight of approximately 2,180 kilograms (4,800 pounds). The battery and electric motor add approximately 200 kilograms (440 pounds) compared to the standard GT63 S. The weight distribution is 54 percent front, 46 percent rear.
The Hybrid System
The Powertrain Layout
The GT63 S E Performance’s hybrid system is unique. The electric motor is mounted at the rear axle, separate from the V8 engine. This layout provides rear-wheel drive capability, with the V8 powering the front wheels and the electric motor powering the rear wheels.
The system does not have a mechanical connection between the V8 and the electric motor. The car can operate in rear-wheel drive (electric only), front-wheel drive (V8 only), or all-wheel drive (both). The transition between modes is seamless.
The Battery
The 6.1 kWh battery is a lithium-ion unit designed for high power density. It can discharge at up to 150 kW, providing the current needed for the electric motor’s peak output. The battery can be charged at up to 3.7 kW, allowing for a full charge in approximately 2 hours.
The battery is mounted at the rear of the car, behind the rear axle. This location contributes to the car’s weight distribution, but it also consumes trunk space.
Regenerative Braking
The GT63 S E Performance features regenerative braking, which captures energy during deceleration and returns it to the battery. The driver can select from four levels of regeneration using the paddle shifters. The highest level allows for one-pedal driving in urban environments.
Chassis and Dynamics
Suspension
The GT63 S E Performance features an air suspension system with adaptive dampers. The system can adjust ride height and damping characteristics based on driving mode and road conditions. The suspension is tuned for a balance of comfort and performance.
Steering
The electric power steering is calibrated for the E Performance’s performance focus. The system provides appropriate weighting and feedback. The steering ratio is variable, with quicker responses in sportier modes.
Brakes
The braking system uses carbon ceramic discs with six-piston calipers at the front and single-piston calipers at the rear. The regenerative braking system is integrated with the friction brakes, providing consistent pedal feel.
Wheels and Tires
The GT63 S E Performance rides on 20-inch front wheels and 21-inch rear wheels, wrapped in high-performance tires. The front tires are 265/40 ZR20, and the rear tires are 295/35 ZR21.
