Mercedes-AMG has introduced its most powerful vehicle to date, the GT 4-Door Coupé, which boasts an impressive 1,153 horsepower electric powertrain. This vehicle marks a significant departure from the brand’s traditional performance sedans, such as the GT63 SE Performance, which utilizes a hybrid 4.0-liter V8 biturbo engine.
Powertrain and Performance
The GT 4-Door Coupé is built on the new 800-volt AMG.EA platform, featuring three innovative axial-flux motors. These motors are designed to optimize power output while minimizing weight and size. The front motor, measuring just 3.5 inches in thickness, can reach over 15,000 rpm and is activated for additional performance or regenerative braking. The two rear motors, each approximately 3.2 inches tall, are paired with a single-speed transmission and can exceed 13,000 rpm. The entire powertrain weighs a mere 309 pounds.
Battery Technology
Powering this system is a 106 kWh battery developed in collaboration with Mercedes-AMG’s Formula 1 program. The battery employs long cylindrical cells, enhancing energy density to 298Wh/kg, while also supporting fast charging capabilities. The vehicle operates at 800 volts and can charge at rates exceeding 600 kW, allowing it to go from 10 to 80 percent charge in just 11 minutes. The GT55 and GT63 models are estimated to achieve a range of 370 to 470 miles on the European WLTP cycle, translating to over 300 miles in EPA terms.
Chassis and Design
To handle its substantial power, the GT 4-Door features multilink front and rear suspensions, complemented by standard air suspension and AMG’s Active Ride Control. The vehicle’s braking system includes regenerative braking for everyday driving, while carbon-ceramic disc brakes are available for high-performance scenarios. The aerodynamic design boasts a 0.22 drag coefficient, with features like bulging fenders and a panoramic glass roof.
The interior is designed for comfort and performance, featuring bolstered seats, a large central display, and a dedicated passenger screen. Drivers can select from seven drive modes and nine traction control settings, with additional features for monitoring racetrack performance.
The GT55 model is set to launch later this year, followed by the GT63 in 2027. While pricing details are not yet available, it is expected to be competitive with the Porsche Taycan Turbo S, which can exceed $200,000.
