The Mercedes-AMG GT 4-Door is set to become an all-electric model for 2027, replacing its gasoline powertrain with a battery pack and a new electric motor setup. The new GT 4-Door will feature a trio of axial-flux electric motors, with two on the rear axle and one on the front. The GT63 variant is expected to deliver a peak of 1153 horsepower, an increase of 322 hp over the previous GT63 S E Performance plug-in hybrid. The GT55 will offer a maximum of 802 horsepower, while the GT53 will produce 536 horsepower.
The bodywork will also be new, utilizing a blend of aluminum, steel, and fiber-reinforced composites to maintain rigidity and a low overall weight. Apart from the GT name and its four-passenger, four-door layout, the new model will feature extensive changes. These include a claimed 0-60 mph time of 2.0 seconds for the GT63, an electronically limited top speed of 186 mph, and a maximum charging speed of 600 kW.
The GT53 will come with two electric motors, while the GT55 and GT63 will feature three. The rear axle motors will provide power under normal conditions, with the front motor acting as a booster for additional traction or acceleration. The vehicle will also include active aerodynamics, rear-wheel steering, and a synthetic soundtrack designed to mimic the sound of an internal combustion engine. An 800-volt, 106-kWh lithium-ion battery will be standard, with an estimated range of 310 to 325 miles. Mercedes-AMG claims the 600-kW charging rate can charge the battery from 10-80 percent in approximately eleven minutes using a suitable DC charger. U.S. market cars will use the NACS plug.
