Mercedes-AMG Unveils 1,153 hp Electric GT 4-Door Coupe to Challenge Porsche
The German manufacturer’s most powerful vehicle to date promises 2.0-second acceleration and direct competition with the Porsche Taycan Turbo S.

Mercedes-AMG has announced the GT 4-Door Coupe, marking its entry into the high-performance electric vehicle segment with a focus on competing directly against the Porsche Taycan. The announcement establishes a tiered release strategy, with the 805 hp GT55 variant arriving later this year and the flagship 1,153 hp GT63 variant scheduled for 2027. This move signals the brand's shift towards its new 800-volt AMG.EA platform, utilising advanced axial-flux motor technology and a 106kWh battery developed in collaboration with the Formula 1 program.
The GT63 variant produces 1,153 hp and 1,475 lb-ft of torque, accelerating from 0 to 60 mph in 2.0 seconds. Mercedes-AMG claims this performance beats the Porsche Taycan Turbo S, which produces 940 hp, by 0.3 seconds in the sprint. The vehicle is built on the new AMG.EA platform, which employs three axial-flux motors to marry high power with reduced weight and size. The entire powertrain weighs just 309 pounds, with the front motor redlining at over 15,000 rpm and the two rear motors hitting just over 13,000 rpm.
Power is managed through a 106kWh battery developed with the Mercedes-AMG Formula 1 program. The unit uses cylindrical cells over four inches long, achieving an energy density of 298Wh/kg. It features a non-conductive oil cooling system to maintain uniform cell temperatures and supports charging at over 600 kW. The manufacturer states this capability allows the vehicle to charge from 10 to 80 percent in 11 minutes.
Range estimates for the GT 4-Door vary between 370 and 470 miles on the European WLTP cycle, equating to over 300 miles on the US EPA cycle. To accommodate the vehicle's 5,400-pound weight and high output, it features multilink front and rear suspensions with standard air suspension, electronic dampers, and AMG's Active Ride Control. Stopping power is provided by carbon-ceramic disc brakes at the front and steel rotor discs at the rear, alongside regenerative braking systems.
The exterior design boasts a 0.22 drag coefficient, with a panoramic glass roof and a body that is five inches longer than the Taycan. Inside, the cabin includes a dedicated front passenger display, seven drive modes, and nine traction control settings. The vehicle can also artificially emulate AMG V8 engine sounds and gear changes. While prices have not been revealed, the GT63 is expected to compete in the same price bracket as the Porsche Taycan Turbo S, which can exceed $200,000.
