Mercedes-AMG has unveiled the GT SUV, its first full-size electric SUV developed entirely in-house by the AMG performance division. The new model combines sports car DNA with electric power, delivering up to 1,153 horsepower, a 0-60 mph time of 2.4 seconds, and DC fast charging capability at up to 710 kilowatts. The 2028 model will launch with three trims: the GT53 SUV, GT55 SUV, and GT63 SUV, with U.S. dealerships expected to receive it in summer 2027.
Three Models, Different Power Setups
The GT53 SUV adopts a dual-motor configuration, placing one electric motor at each axle. A two-speed transmission at the rear enhances acceleration and highway efficiency, with a shorter first gear for quick starts. In contrast, the GT55 and GT63 models feature three electric motors—one at the front and two at the rear. The front motor can disengage to conserve energy and reactivate when extra traction or power is needed. All three trims include AMG Performance 4MATIC+ all-wheel drive, while the GT55 and GT63 can direct power to individual rear wheels for improved handling.
Performance metrics vary significantly across the lineup. The GT53 produces 362 continuous horsepower and 536 peak horsepower, achieving 0-60 mph in 4.1 seconds with a top speed of 143 mph. The GT55 steps up to 711 continuous horsepower and 805 peak horsepower, hitting 60 mph in 3.0 seconds and reaching 168 mph. The GT63 matches the GT55’s continuous output but peaks at an impressive 1,153 horsepower while also topping out at 168 mph.
Charging Speed and Range
The GT SUV operates on an 800-volt electrical system, paired with model-specific battery packs. The GT53 is equipped with a 106.0 kWh battery, while the GT55 and GT63 both use larger 128.0 kWh units. Charging capabilities differ: the GT53 supports up to 600 kilowatts, whereas the GT55 and GT63 can absorb power at 710 kilowatts. Mercedes claims the GT53 can add 236 miles of WLTP-rated range in 10 minutes of charging, while the higher trims achieve 280 miles in the same timeframe. The GT63 projects a WLTP range between 385 and 435 miles, though U.S. EPA estimates remain unannounced.

Suspension and Road manners
To manage its size and performance, the GT SUV features a new AMG Active Ride Control+ suspension system. Standard on the GT63 and optional on the GT55, this setup uses hydraulic dampers and adjustable air springs to minimize body roll without traditional anti-roll bars. The system reduces nose-dive during braking and limits wheel lift under acceleration, while maintaining ride comfort on rough surfaces. The GT63 also includes the AMG Dynamic Plus Package, which adds a Race Engineer Control Unit for adjusting motor response, handling, and traction via three rotary controls.
The AMG GT SUV simulates traditional engine sounds through AMGForce Sport+, using over 100 measurements and 16 microphones to capture real V8 and six-cylinder acoustics. Drivers can shift gears using steering-wheel paddles, while seat vibrations and customizable displays enhance the experience. Seven drive modes, including Comfort, Sport, AMGFORCE Sport+, Race, Slippery, Eco, and Individual, allow tailored settings for varying conditions. The GT SUV’s design mirrors its sedan sibling, with a sharp roofline, wide stance, and frameless windows, complemented by active aerodynamics like the Aerokinetics Airpanel system and an active rear spoiler on the GT55 and GT63. Inside, a 10.2-inch digital instrument cluster pairs with a 14.0-inch central infotainment screen, with an optional 14.0-inch passenger display.
Power Output and Torque Figures
The GT53 SUV delivers 590 lb-ft of torque, while the GT55 and GT63 models exceed 1,300 lb-ft. The GT55 produces 1,372 lb-ft, and the GT63 peaks at 1,475 lb-ft, enhancing its launch and acceleration capabilities. These torque figures complement the electric motor configurations, with the GT55 and GT63’s tri-motor setup enabling precise power distribution across all wheels.
Platform Development and Pending Details
Mercedes has not yet disclosed U.S. pricing or EPA-estimated range figures, though WLTP projections for the GT63 range from 385 to 435 miles. Final U.S. ratings will likely differ from European values. Additional specifications and pricing details are expected closer to the summer 2027 dealership launch.
