Mercedes-AMG Launches First Ground-Up Performance SUV with 1,150hp and 710kW Charging
The 2028 Mercedes-AMG GT SUV combines three axial flux motors delivering over 1,150 horsepower with ultra-fast 800-volt charging architecture, scheduled for U.S. arrival next summer.
What happened
Mercedes-AMG unveiled the 2028 GT SUV, its first full-size SUV developed entirely in-house from the ground up in the brand's 59-year history. The vehicle comes in three trims—GT 53, GT 55, and GT 63—with the flagship GT 63 delivering 1,153hp via three axial flux motors. The 800-volt architecture supports charging speeds up to 710kW on the 128kWh battery and 600kW on the 106kWh battery, enabling 10–80 percent charge in 12 minutes or 450km (280 miles) of range in 10 minutes. Built on Mercedes' AMG.EA architecture, the GT 63 weighs 5,941lbs and achieves an estimated maximum range of 435 miles. The vehicle launches in the U.S. next summer with features including active hydraulic suspension, six-degree active rear-axle steering, a 14-inch display running MB.OS platform with integrated AI agents, and the Predictive Performance Manager for dynamic track driving.
Context
This SUV positions Mercedes-AMG to compete directly with high-performance electric alternatives like the Porsche Cayenne Turbo Electric (which delivers lower horsepower and 320kW charging) and the Lucid Gravity. The 710kW charging capability significantly outpaces competitors, addressing a key EV advantage metric. By developing the first ground-up AMG SUV and engineering it with bespoke suspension technology and F1-inspired battery systems, Mercedes is expanding its performance brand into the high-volume SUV segment while maintaining sports-car handling characteristics. The vehicle's weight parity with competitors despite its scale suggests engineering focus on performance efficiency. The inclusion of simulated AMG engine sounds and the Predictive Performance Manager indicates Mercedes is designing the driving experience specifically for performance enthusiasts accustomed to traditional combustion-engine dynamics.
