Mercedes-AMG has revealed the 2028 GT SUV, an all-electric performance vehicle with a top output of 1,153 horsepower and three electric motors in its most powerful configuration. The Mercedes-AMG GT SUV electric powertrain marks the first full-size SUV the performance brand has developed entirely in-house in its 59-year history, according to The Verge. The model is scheduled to arrive at US dealerships in summer 2027.
For fans of AMG’s gas-powered lineup, the GT SUV represents the brand’s attempt to carry its performance identity into a fully electric era, right down to synthetic engine sound and simulated gear shifts built into the driving experience.
Powertrain And Performance Claims
The GT SUV comes in three trims: GT53, GT55 and GT63, according to Motor1. The GT55 and GT63 each use three electric motors, one up front and two at the rear, while the GT53 relies on two motors, one at each axle.
Peak output tops out at 1,153 horsepower and 1,475 lb-ft of torque in the GT63, which also produces 711 horsepower continuously, per Motor1. The GT55 peaks at 805 horsepower and 1,372 lb-ft of torque with the same 711-horsepower continuous rating as the GT63. The GT53 produces a peak of 536 horsepower and 590 lb-ft of torque, with 362 horsepower available continuously.
Acceleration claims vary slightly between outlets. Motor1 reports the GT63 reaches 60 mph in 2.6 seconds, while The Verge lists a 2.4-second time for the same trim. The GT55 hits 60 mph in 3.0 seconds and the GT53 in 4.1 seconds, according to Motor1. Top speed reaches 168 mph for both the GT55 and GT63, while the GT53 tops out at 143 mph.
The GT53 also includes a two-speed transmission at the rear axle, pairing a shorter first gear for acceleration with a taller second gear for highway efficiency, Motor1 reported. In the GT55 and GT63, the front motor can switch off entirely when not needed to conserve energy.
Battery, Charging And Range
The SUV rides on Mercedes’ AMG.EA high-performance architecture with an 800-volt electrical system, according to The Verge. Buyers choose between two battery packs: a 128kWh unit for the GT55 and GT63, and a 106kWh pack for the GT53.
Charging speed reaches up to 710 kilowatts on the larger battery and 600 kilowatts on the smaller pack, The Verge reported. That allows a 10-to-80% charge in 12 minutes, and Mercedes-AMG says the GT SUV can add roughly 280 miles of WLTP range from just 10 minutes at a fast charger. The 128kWh battery carries an estimated maximum range of 435 miles.
The battery design borrows from Formula 1 development, using NCMA cathodes, silicon-containing anodes and cylindrical cells cooled by electrically nonconductive oil that flows directly around each cell, according to The Verge.
Chassis, Sound And Cabin Features
Active hydraulic suspension elements are built to cancel out pitch and roll during acceleration, hard braking and cornering, The Verge reported. Three-stage air springs and six-degree active rear-axle steering come standard across the lineup, and Mercedes-AMG’s Active Ride Control+ suspension system is standard on the GT63 and optional on the GT55.
To preserve AMG’s performance identity without a combustion engine, the GT SUV pipes in recorded sounds. The GT55 and GT63 reproduce the sound of an AMG V-8, while the GT53 mimics a six-cylinder engine, according to MotorTrend. The system simulates mechanical gear shifts through the paddle controls, offers adjustable sound profiles and even feeds physical vibrations into the seats.
Cargo space includes a 2.8-cubic-foot front trunk and 21.4 cubic feet behind the rear seats, which fold and accommodate a three-person bench, per Motor1. The cabin features a 14.0-inch central infotainment screen, a 10.2-inch driver’s display and an optional 14.0-inch screen for the front passenger, running Mercedes’ latest operating system with a built-in virtual assistant, MotorTrend reported. Other details include a panoramic glass roof that switches between transparent and opaque modes, frameless side windows and an active rear spoiler that deploys at 93 mph.
Mercedes-AMG will build the GT SUV in Sindelfingen, Germany, and customers can opt into the brand’s Manufaktur program for 60 additional exterior color choices and further customization, according to MotorTrend.
How It Compares With Rival Electric SUVs
At 5,941 lbs, the GT63 SUV comes in slightly lighter than the Lotus Eletre R, which weighs 6,007 lbs, and the Lucid Gravity, at 6,100 lbs, according to The Verge. It lands nearly identical in weight to the Porsche Cayenne Turbo Electric’s 5,960 lbs.
On output and charging speed, the GT63’s 1,153 horsepower and 710-kilowatt charging capability could put it ahead of both the Porsche Cayenne Turbo Electric and the Lucid Gravity, The Verge noted, pointing out that Porsche’s charging tops out at 320 kilowatts by comparison.
What’s Next
Mercedes-AMG has not released US pricing for the GT SUV lineup. The automaker confirmed the vehicle is set to reach US dealerships in summer 2027, giving buyers roughly eight months from now before order details and final specifications are expected to firm up.
