Mercedes-AMG has unveiled the AMG GT SUV, an all-electric performance utility vehicle that the company says is the first full-size SUV developed entirely in-house by the AMG division. The new model is scheduled to reach the United States next summer as a 2028 vehicle, and it is intended to translate the brand’s high-output electric powertrain into a larger, more practical body style.

The headline figure belongs to the flagship GT 63: 1,153 horsepower from three axial-flux motors. Mercedes-AMG will also offer GT 53 and GT 55 versions, placing the vehicle in an increasingly competitive upper tier of electric performance SUVs that includes the Porsche Cayenne Turbo Electric and Lucid Gravity.

A dedicated AMG electric platform

The GT SUV is built on Mercedes’ AMG.EA architecture, a high-performance electric platform developed for AMG products. That distinction is central to the launch. AMG has long sold performance versions of Mercedes SUVs, but the company says this is its first full-size SUV designed by the performance division from the ground up.

Mercedes-AMG is positioning the vehicle around a familiar performance-SUV compromise: sports-car responses alongside room for people and cargo. The outcome in real-world driving will depend on factors such as weight, suspension tuning, software calibration and the vehicle’s range under demanding use. Those details will matter because power alone does not settle how convincingly an electric SUV feels on a road or track.

Still, the announced powertrain places the GT SUV among the most extreme production-oriented electric utility vehicles disclosed to date. The three-motor setup is the same basic motor count used in AMG’s GT four-door electric coupe, according to the supplied report. In the SUV, it serves as the foundation for the top model’s four-figure horsepower claim.

Charging is part of the performance pitch

AMG is also making unusually high charging rates part of the vehicle’s identity. The GT 63 and GT 55 are specified with a 128-kilowatt-hour battery and support charging at up to 710 kilowatts through an 800-volt electrical architecture. The GT 53 uses a 106-kilowatt-hour battery and is rated for charging up to 600 kilowatts.

For the two larger-battery versions, Mercedes-AMG says a charge from 10 percent to 80 percent can take 12 minutes under suitable conditions. It also says the vehicle can add as much as 450 kilometers, or roughly 280 miles, of WLTP-rated range in 10 minutes. Those figures depend on access to compatible high-power chargers, battery temperature and other conditions, but they signal an effort to make short charging stops more useful on long trips.

The 128-kilowatt-hour versions are estimated to reach a maximum range of 435 miles. That is an estimated figure rather than a confirmed U.S. EPA rating, and the source describes the 280-mile figure in the European WLTP test cycle. Buyers will need final market-specific ratings to compare the SUV directly with alternatives.

Battery cooling drawn from racing ideas

Mercedes-AMG says the battery system uses technology inspired by Formula 1, including NCMA cathodes, silicon-containing anodes and cylindrical cells. The company also describes a thermal-management approach in which electrically nonconductive oil flows directly around individual cells to help maintain more uniform temperatures.

Thermal control is particularly relevant for a vehicle that is designed to deliver high power and accept rapid charging. Batteries generate heat when they discharge hard or recharge quickly. Keeping cell temperatures within an appropriate operating range can influence performance consistency, charging capability and battery durability. The manufacturer’s use of direct oil circulation is therefore more than a specification-sheet flourish: it is part of the engineering required to support the announced output and charging claims.

As with all manufacturer claims, the practical results will have to be assessed in independent testing. Fast charging can be limited by infrastructure as well as the vehicle, while range varies with speed, weather, wheel and tire choices, terrain and the use of climate control. A large battery may help with distance, but it also adds mass that suspension, brakes and motors must manage.

An escalation in electric SUV performance

The AMG GT SUV arrives as luxury manufacturers seek to define the electric era not only through efficiency but also through acceleration, charging speed and software-controlled performance. High-output electric motors make enormous power figures technically achievable; the challenge is integrating that power into vehicles customers can use every day.

Mercedes-AMG’s planned three-trim lineup suggests it will offer different entry points while reserving the most dramatic power and charging specifications for the GT 63. The company has not, in the supplied material, detailed U.S. pricing. It has, however, laid out a clear ambition: deliver a large electric SUV with sports-car-level output, an 800-volt charging system and a battery designed for repeated high-demand use.

Whether the vehicle meets that ambition will become clearer closer to launch. For now, the announcement marks a significant step for AMG: its first clean-sheet full-size SUV is also an EV, and it is being introduced with performance and charging claims meant to put it at the sharp end of the electric luxury market.
