Mercedes-AMG Unveils 1,150hp Electric GT SUV with 710kW Fast Charging

First Ground-Up Electric SUV

Mercedes-AMG has unveiled the 2028 GT SUV, marking the first time in its 59-year history that the performance brand has developed a full-size SUV entirely in-house from the ground up. This electric vehicle is scheduled to arrive in the US next summer.

Performance and Trims

The AMG GT SUV will be available in three trims: GT 53, GT 55, and the flagship GT 63. The GT 63 model produces 1,153 horsepower using three axial flux motors, the same setup found in the GT four-door coupe. This output exceeds that of the Porsche Cayenne Turbo Electric.

The SUV is built on Mercedes' high-performance AMG.EA architecture, designed to integrate sports-car handling with the practicality of a full-size SUV.

Advanced Charging and Battery Technology

The vehicle features an 800-volt architecture, enabling fast charging speeds. The 128kWh battery in the GT 63 and GT 55 trims supports up to 710kW charging, while the 106kWh battery in the GT 53 supports 600kW. This allows for a 10-80 percent charge in 12 minutes or up to 450km (280 miles) of WLTP range in 10 minutes.

The battery incorporates F1-inspired technology, utilizing specialized NCMA cathodes, silicon-containing anodes, and cylindrical cells. An electrically nonconductive oil circulates around each cell for uniform thermal management, which supports continuous high-power delivery and extends battery life. The 128kWh battery trims are estimated to offer a maximum range of 435 miles.

Handling and Suspension

To improve handling for a full-size SUV, Mercedes-AMG has replaced traditional mechanical roll bars with a new suspension system. This system uses active hydraulic elements to control pitch and roll during acceleration, braking, and cornering. It also includes three-stage air springs and standard six-degree active rear-axle steering.
