Earlier this year, Mercedes’ AMG performance brand caught our attention with the four-door GT coupe, a supercharged sports sedan with three axial-flow engines producing more than 1,150 horsepower. Well, now here’s its beefier cousin, the 2028 Mercedes-AMG GT SUV, an equally powerful, ultra-fast-charging electric people mover.
The AMG GT SUV (let’s say five times faster) marks the first time in the performance brand’s 59-year history that it has developed a full-size SUV entirely in-house from the ground up. Scheduled to arrive in the United States next summer, the new electric vehicle is built on Merc’s high-performance AMG.EA architecture to combine the handling of a sports car with the suburban practicality of a full-size SUV.
It will be available in three versions – GT 53, GT 55 and the flagship GT 63 – the top-of-the-range model developing 1,153 hp via the same three axial flow engines fitted to the four-door coupe. This beats the Porsche Cayenne Turbo Electric with Launch Control, which is sure to cause some tough collisions around Stuttgart.
Thanks to an 800-volt architecture, the SUV supports ultra-fast charging speeds of up to 710 kW on the 128 kWh battery (GT 63 / GT 55) and 600 kW on the 106 kWh battery (GT 53). Drivers can charge 10-80% in 12 minutes or gain up to 450 km (approximately 280 miles) of WLTP range in just 10 minutes. The 128 kWh battery versions will have an estimated maximum range of 435 miles.
By the way, this battery? It uses F1-inspired technology with specialized NCMA cathodes, silicon-containing anodes and cylindrical cells. An electrically non-conductive oil flows directly around each individual cell for uniform thermal management, enabling continuous high power delivery and long battery life. Mercedes has been quietly at the forefront of battery technology for some time now, with the AMG GT SUV being just the latest example. The 710 kW charging speed, in particular, could give Mercedes an extra advantage over Porsche’s 320 kW speeds.
For a full-size SUV, the AMG GT looks like it could handle like a vehicle half the size. Mercedes-AMG has replaced traditional mechanical roll bars with a newly developed suspension that uses active hydraulic elements to eliminate pitch and roll during acceleration, hard braking and cornering. Combined with standard three-stage air springs and six-degree active rear axle steering, it claims to balance trail precision and long-distance comfort.
But just because he’s a big guy doesn’t mean he’ll tip the scales. The AMG GT 63 SUV weighs 5,941 pounds, making it slightly lighter than the Lotus Eletre R (6,007 pounds) and Lucid Gravity (6,100 pounds), and almost identical to the Porsche Cayenne Turbo Electric (5,960 pounds).
Silence is golden, except for a performance brand’s EV engineering team. This means playing the recorded sounds of real AMGs – in this case, the legendary AMG V8 and six-cylinder engines – to preserve AMG’s “emotional” identity. Mercedes prides itself on using real engine sounds rather than synthetic electric vehicle sounds, although some may disagree. The system even simulates mechanical gear changes with steering wheel controls, offers adjustable sound profiles and incorporates physical seat vibrations – so you can always feel like there’s a real engine under that hood instead of a 78-liter trunk. The so-called AMGFORCE Sport+ driving program is offered as standard on all three versions of the Mercedes-AMG GT SUV.
Inside, you’ll find the MB.OS platform on your 14-inch screen, with an army of AI agents from ChatGPT, Microsoft, and Google on hand to direct. Use them to configure navigation, discover random locations, search the web, tell bad jokes, or any other reason people use AI in their cars. Merc’s own in-car AI system can handle physical elements, like adjusting the HVAC, changing driving modes or manipulating lighting, all via voice commands.
1/1
Beyond voice and navigation, the AMG GT SUV applies AI to high-performance track driving via what’s called the Predictive Performance Manager. Mercedes says PPM uses track mapping data to dynamically accelerate or increase electric motor power depending on topography, saving battery power on descents or winding technical sections so that full power is available on steep inclines and long straights. It could also mean faster and more consistent overall lap times by eliminating battery overheating and power throttling during track driving – something an AMG enthusiast would probably appreciate.
Mercedes has yet to release official pricing, although we can expect something closer to its official launch.
