Mercedes-AMG GT SUV Debuts with 1,169 Horsepower, Axial-Flux Motors, and 710 kW Charging

Mercedes-AMG officially unveiled the AMG GT SUV on October 17, 2026, at the Mercedes-Benz Museum in Stuttgart, Germany. The vehicle is the Affalterbach performance division’s first full-size sport utility vehicle developed entirely in-house. Built on the dedicated 800-volt AMG Electric Architecture, designated as AMG.EA, the vehicle is the second production model to utilize this platform following the previously shown GT 4-Door Coupe. Mercedes-Benz Group AG stated during the premiere that customer deliveries in Europe will begin in mid-2027, with North American arrivals scheduled for summer 2027 under the 2028 model year.

The powertrain lineup centers on high-density axial-flux motors, which direct magnetic flux parallel to the axis of rotation instead of radially outward. This configuration produces a flat disc profile that reduces motor mass and packaging space. The motors were engineered by YASA, a British electric motor manufacturer acquired by Mercedes-Benz in 2021. According to technical documentation released by Mercedes-AMG, the flagship GT 63 SUV uses three axial-flux motors, placing one motor on the front axle and two motors on the rear axle. The combined system produces 860 kilowatts of power, equivalent to 1,169 metric horsepower, and 2,000 Newton meters of torque. A disconnect unit automatically decouples the front motor during low-load driving to minimize parasitic energy drag.

Acceleration figures published by Mercedes-AMG quote a zero to 100 kilometer per hour sprint in 2.7 seconds for the GT 63, which drops to 2.5 seconds when measured using an industry-standard one-foot rollout allowance. Top speed reaches an electronically limited 270 kilometers per hour with the optional AMG Driver’s Package. Performance electric vehicles frequently suffer thermal throttling, meaning motor output decreases sharply after repeated full-throttle acceleration runs. To address this issue, Mercedes-AMG published a continuous power rating of 530 kilowatts for the GT 63, indicating that more than 60 percent of peak output remains available during continuous track driving. The intermediate GT 55 variant also utilizes three axial-flux motors to generate 600 kilowatts, or 816 horsepower, while the entry GT 53 variant uses two conventional synchronous motors producing 400 kilowatts, or 544 horsepower.

Energy storage relies on an 800-volt battery pack featuring directly cooled cylindrical cells. Mercedes-AMG High Performance Powertrains, the company’s Formula 1 engine and hybrid research unit based in Brixworth, England, contributed to the thermal architecture. An electrically non-conductive dielectric cooling oil flows directly around every individual cell. Conventional liquid cooling systems route fluid through external perimeter plates. According to technical briefings published by Mercedes-AMG, this direct immersion stabilizes cell temperatures during sustained high-load discharge and rapid charging cycles. Usable energy capacity is 128 kilowatt-hours in the GT 63 and GT 55, while the GT 53 uses a smaller pack with a usable capacity of 106 kilowatt-hours.

Charging specifications set a new commercial benchmark for passenger electric vehicles. Mercedes-AMG confirmed that the 128-kilowatt-hour battery accepts direct current fast charging at peak rates up to 710 kilowatts. Mercedes-AMG data indicates that this charging rate can replenish 450 kilometers of driving range on the Worldwide Harmonized Light Vehicles Test Procedure cycle in 10 minutes. A replenishment from 10 to 80 percent state of charge requires 12 minutes under optimal conditions. The 106-kilowatt-hour battery accepts charging rates up to 600 kilowatts, completing a 10 to 80 percent charge in 11 minutes.

Can buyers actually use a 710-kilowatt charging speed on public roads? For the foreseeable future, public charging infrastructure will be the operational bottleneck. Data from the European Alternative Fuels Observatory, a European Commission body tracking charging deployments, and the United States Department of Energy shows that standard public fast chargers currently peak between 350 and 400 kilowatts. CharIN, the global industry association responsible for open charging standards, has published specifications for Megawatt Charging Systems capable of higher outputs, but those installations are currently restricted to commercial heavy truck corridors. In daily practice, AMG GT SUV drivers will charge at the maximum rate permitted by existing 350-kilowatt dispensers, awaiting future commercial hardware upgrades. Mercedes-AMG confirmed that the vehicle supports CCS Type 2, CCS Type 1, and the North American Charging Standard across its respective regional delivery variants.

Controlling the mass of a large electric sport utility vehicle requires complex chassis management. Mercedes-AMG equipped the vehicle with an active suspension system called AMG Active Ride Control plus. Technical specifications released by the automaker indicate that the setup removes conventional steel anti-roll bars entirely. High-speed electro-hydraulic actuators located at each wheel react independently to lateral forces, generating counter-pressure to keep the vehicle level during aggressive cornering. The system simultaneously counteracts pitch during hard acceleration and braking. Standard rear-axle steering turns the rear wheels up to 3 degrees in opposition to the front wheels below 60 kilometers per hour, reducing the physical turning circle in tight parking spaces.

To bridge the gap between traditional combustion sports cars and electric mobility, Mercedes-AMG developed synthetic sound and sensory feedback programs. Mercedes-Benz Media Newsroom USA stated that the AMGFORCE Sport plus drive mode uses specialized software algorithms to pipe synthesized V8 and six-cylinder acoustic signatures through the cabin speakers and external sound projectors. The software pairs these sounds with electro-mechanical vibrators embedded inside the seat cushions and momentary torque interrupts that mimic the mechanical shift shock of a multi-gear transmission. The manufacturer designed these tactile cues to provide drivers with intuitive speed and load references without requiring them to glance down at the digital instrument display.

ElectricDrives, a British electric vehicle publication, reported that Mercedes-AMG opened European order banks on October 19, 2026, with German pricing starting at 113,050 euros including value-added tax for the base GT 53 model. Mercedes-AMG has not yet released pricing for the higher-output GT 55 and GT 63 variants, nor has Mercedes-Benz USA announced pricing for the North American market. When the vehicle reaches dealerships in 2027, its chief market rival will be the upcoming Porsche Cayenne Electric, which Porsche AG has confirmed will also rely on an 800-volt platform with multi-motor drive units.

Official certification documents from the European Union and the United States Environmental Protection Agency have not yet been published. Mercedes-AMG has submitted preliminary combined energy consumption estimates ranging between 18.8 and 23.8 kilowatt-hours per 100 kilometers under the WLTP test cycle, with targeted total range reaching up to 700 kilometers on the 128-kilowatt-hour pack. Final curb weight figures, cargo capacities, and United States official range estimates remain unconfirmed by the manufacturer. Mercedes-AMG stated that final type approval and standardized range ratings will be released closer to regional retail launches in early 2027.
