Mercedes-AMG Unveils First In-House Electric SUV with 1,153 Horsepower and 710 kW Charging
Built on the dedicated AMG.EA platform, the 2028 GT SUV features direct oil-cooled battery cells, active hydraulic roll stabilization, and AI-driven track power management.

Mercedes-AMG has introduced the 2028 Mercedes-AMG GT SUV, marking the performance division's first full-size SUV designed entirely in-house from the ground up across its 59-year history. Built on the automaker's dedicated AMG.EA electric platform, the model is scheduled to reach the United States next summer, according to reporting by The Verge (https://www.theverge.com/transportation/1013088/mercedes-amg-gt-suv-price-specs-performance).
The SUV will arrive in three trim tiers: the GT 53, GT 55, and the flagship GT 63. The GT 63 utilizes three axial flux electric motors to deliver 1,153 horsepower, matching the output of the brand's GT four-door coupe and exceeding the output of the Porsche Cayenne Turbo Electric.
Operating on an 800-volt electrical architecture, the GT 63 and GT 55 carry a 128 kWh battery pack supporting DC fast-charging rates up to 710 kW, while the base GT 53 employs a 106 kWh pack rated for up to 600 kW. Mercedes estimates the 128 kWh configuration will achieve a maximum range of 435 miles, with high-power charging replenishing 10 to 80 percent of capacity in 12 minutes or adding up to 280 miles (450 kilometers) of WLTP-rated range in 10 minutes.
The battery pack employs cylindrical cells with nickel-cobalt-manganese-aluminum (NCMA) cathodes and silicon-containing anodes. For thermal regulation under sustained load, an electrically nonconductive oil circulates directly around individual cells to provide uniform thermal dissipation.
Chassis hardware departs from conventional setups by replacing mechanical anti-roll bars with active hydraulic components designed to eliminate pitch and roll during acceleration, braking, and cornering. The platform also integrates three-stage air springs and standard six-degree active rear-axle steering. Curb weight for the GT 63 is rated at 5,941 pounds, coming in just under the Lucid Gravity (6,100 pounds) and Lotus Eletre R (6,007 pounds) while aligning closely with the Porsche Cayenne Turbo Electric (5,960 pounds).
The cabin incorporates a 14-inch center display running Mercedes-Benz's MB.OS platform, featuring integrated AI services from ChatGPT, Microsoft, and Google alongside an onboard voice system for controlling climate settings, vehicle lighting, and drive modes. Across all trims, the standard AMGFORCE Sport+ program delivers recorded AMG V8 and six-cylinder engine audio, simulated paddle-shift gear steps, and haptic seat feedback. For track use, Mercedes-AMG added a Predictive Performance Manager that uses circuit topography data to modulate electric motor output dynamically, reserving battery reserves for high-demand straights and climbs while preventing thermal throttling. Mercedes has not yet announced official retail pricing.
