Mercedes-AMG has unveiled the 2028 Mercedes-AMG GT SUV, the first full-size SUV the performance brand has developed entirely in-house in its 59-year history. The vehicle is scheduled to reach the US market next summer. It is built on Mercedes' high-performance AMG.EA architecture, which the company says combines sports-car handling with the practicality of a full-size SUV.

The GT SUV will come in three trims: GT 53, GT 55, and the flagship GT 63. The top model produces 1,153 horsepower through the same three axial flux motors used in the AMG GT four-door coupe. That output exceeds the Porsche Cayenne Turbo Electric with Launch Control.

An 800-volt architecture supports charging speeds of up to 710kW on the 128kWh battery offered in the GT 63 and GT 55, and up to 600kW on the 106kWh battery in the GT 53. Drivers can charge from 10 to 80 percent in 12 minutes, or gain up to 450km (about 280 miles) of WLTP range in 10 minutes. The 128kWh versions carry an estimated maximum range of 435 miles. The battery uses F1-inspired technology with specialized NCMA cathodes, silicon-containing anodes, and cylindrical cells, with an electrically nonconductive oil flowing directly around each cell for uniform thermal management.

Mercedes-AMG replaced traditional mechanical roll bars with a suspension using active hydraulic elements intended to eliminate pitch and roll during acceleration, braking, and cornering. The system is paired with three-stage air springs and standard six-degree active rear-axle steering. The GT 63 SUV weighs 5,941lbs, slightly lighter than the Lotus Eletre R at 6,007lbs and the Lucid Gravity at 6,100lbs, and nearly identical to the Porsche Cayenne Turbo Electric at 5,960lbs.

The SUV pipes recorded sounds of real AMG V8 and six-cylinder engines into the cabin rather than synthetic EV tones, and simulates mechanical gear shifts with paddle controls. Adjustable sound profiles and physical seat vibrations are included. The AMGFORCE Sport+ drive program is standard across all three trims.

Inside, the MB.OS platform runs on a 14-inch display with AI agents from ChatGPT, Microsoft, and Google, while Mercedes' own onboard AI handles HVAC, drive modes, and lighting via voice commands. A Predictive Performance Manager uses track-mapping data to throttle or boost motor output based on topography, conserving battery on downhills and winding sections so full power is available on inclines and straights. Mercedes has not released official pricing.
