Mercedes-AMG has presented the 2028 electric GT SUV, marking the brand’s first attempt to develop a full-size SUV from the ground up in-house during its 59-year history. According to Mercedes specifications, the vehicle combines sports-car performance with the practicality associated with large family-use vehicles, on the high-performance AMG.EA platform.
Three Trims and Three Motors
The vehicle will be available in three trims: GT 53, GT 55, and GT 63. The top GT 63 trim comes with three axial-flux electric motors producing a combined 1,153 horsepower, the same motors used in the four-door GT variant. Mercedes says this output exceeds that of the Porsche Cayenne Turbo Electric when Launch Control is activated.
The company has not announced the official price, while the vehicle is scheduled to launch in the United States next summer.
Fast Charging and Batteries with Formula 1-Inspired Technologies
The GT SUV uses an 800-volt electrical architecture. The GT 63 and GT 55 trims receive a 128-kilowatt-hour battery supporting charging at up to 710 kilowatts, while the GT 53 uses a 106-kilowatt-hour battery with charging capability of up to 600 kilowatts. Mercedes says charging the battery from 10 to 80 percent takes 12 minutes, or that up to 450 kilometers of range can be added according to the WLTP standard in 10 minutes.
The estimated maximum range of versions equipped with the 128-kilowatt-hour battery reaches 435 miles. The battery uses an NCMA-type cathode, silicon-containing anodes, and cylindrical cells, along with a nonconductive oil surrounding each cell to help manage heat evenly. The source did not specify the testing conditions underlying the charging and range figures.
Engineering to Handle the Weight of a Large SUV
Mercedes-AMG has replaced conventional mechanical anti-roll bars with a suspension system that uses active hydraulic elements to limit body roll and pitch during acceleration, braking, and cornering. The vehicle also includes three-stage air springs and active rear-axle steering with an angle of six degrees.
The GT 63 weighs approximately 5,941 pounds, slightly less than the 6,007-pound Lotus Eletre R and the 6,100-pound Lucid Gravity, and close to the 5,960-pound Porsche Cayenne Turbo Electric.
What Changes in Practice?
The vehicle’s specifications are not limited to increased output; Mercedes uses the Predictive Performance Manager to adjust motor output based on racetrack map data and the nature of the route. According to the company, the system can reduce battery consumption on downhill sections and technical corners, then provide full power on climbs and long straights, potentially helping reduce heat-related performance degradation during track driving.
The vehicle also adds the standard AMGFORCE Sport+ system across all three trims, along with recorded sounds of AMG eight- and six-cylinder engines, simulated gear changes through paddles behind the steering wheel, and seat vibrations. Inside the cabin, the MB.OS platform operates on a 14-inch display, with artificial-intelligence agents from ChatGPT, Microsoft, and Google for tasks such as navigation and search, while Mercedes’ voice system controls functions such as climate control, driving modes, and lighting.
The GT SUV reveals Mercedes-AMG’s approach to addressing two conflicting challenges in high-performance electric vehicles: maintaining sports-car responsiveness while managing the weight and heat of a large vehicle. However, the final price, details of the actual range, and charging performance under everyday-use conditions remain open questions until the company announces more information.
