Mercedes-AMG’s identity was once defined by thunderous V8 engines and brute-force performance. Its fastest SUVs were created by fitting ferocious powertrains into practical bodies and tuning the chassis for maximum aggression. The new Mercedes-AMG GT SUV marks a dramatic departure: it is the first SUV developed entirely by AMG as a purpose-built electric performance vehicle, and it arrives with numbers that push the brand into hypercar territory.
Built on the dedicated AMG.EA architecture, the range-topping GT 63 SUV uses three electric motors — one at the front and two at the rear — including slim axial-flux units developed with Yasa. Combined output reaches 860 kW, equivalent to 1,169 hp and 1,480 lb-ft of torque. That exceeds the AMG One’s 1,048 hp and delivers nearly twice the impact of the combustion GLE 63 S. Continuous power is rated at 530 kW, or 721 hp.
The flagship’s acceleration is startling for a large luxury SUV. AMG quotes 0 to 62 mph in 2.7 seconds, or 2.5 seconds using a one-foot rollout. It reaches 124 mph in 7.2 seconds, and with the optional AMG Driver’s Package the electronically limited top speed rises to 270 km/h. The feat is made more surreal by the vehicle’s mass: depending on battery choice, it weighs between 5,699 and 5,941 lb.
To keep such a heavy, high-output vehicle composed, AMG replaces conventional anti-roll hardware with AMG Active Ride Control+. The system combines air springs with hydraulically linked dampers and an 8.2-liter pressure reservoir, actively managing body movement during cornering, acceleration, and braking. Rear-axle steering adds further agility, turning the rear wheels up to 6 degrees opposite the fronts below 50 mph and slightly with them at higher speeds to improve stability.
The GT SUV’s shape is sleeker than expected for its class. At 200.2 inches long, 78.8 inches wide, and 65.2 inches tall, with a 119.7-inch wheelbase, it sits lower than typical SUV rivals. Compared with the GLE 63 S, it is longer, slightly narrower, and significantly lower, helping reduce drag to 0.27 Cd. Competitors include the Lotus Eletre R, electric Porsche Cayenne, and BMW iX M70, though the AMG stands out for its extreme output and specialized engineering.
The battery and thermal management are central to the GT SUV’s performance. Buyers can select usable capacities of 106 kWh or 128 kWh, using cylindrical NCMA cells. Rather than conventional underside cooling, AMG immerses the cells in non-conductive dielectric oil controlled by a central cooling hub. The 128 kWh version supports up to 710 kW on an 800-volt charger, enabling a 10% to 80% charge in about 12 minutes. AMG claims up to 282 miles of range can be added in 10 minutes, with maximum claimed range reaching 435 miles.
Inside, the GT SUV emphasizes a sports-car atmosphere rather than a traditional family-crossover feel. The driver sits low in heavily bolstered seats, facing a 10.2-inch instrument display and a 14.0-inch central touchscreen powered by MB.OS. An optional passenger display is available. Thanks to the SUV’s packaging, the floor is flat, improving rear comfort. Cargo capacity is 21.4 cubic feet behind the rear seats, expanding to 61.4 cubic feet when folded, while a 3.92-cubic-foot front trunk provides space for charging equipment.
AMG also gives the electric SUV a more emotional character through AMGFORCE Sport+. The mode uses more than 100 sound profiles inspired by AMG’s combustion performance cars, with audio that responds to throttle input. Simulated gear shifts can be triggered via paddles, and seat-mounted haptics add physical impact. The AMG Race Engineer controls allow drivers to adjust motor response, handling behavior, and traction settings with greater precision.
Beyond the flagship GT 63, the lineup includes the GT 53 and GT 55. The GT 53 uses two conventional permanent-magnet motors producing 400 kW, or 544 hp, and 590 lb-ft of torque, aided by a rear two-speed gearbox for a 0-to-62 mph time of 4.2 seconds. In Germany, pricing starts from £96,410. The GT 55 adopts the tri-motor axial-flux system with 600 kW, or 816 hp, and 1,372 lb-ft, cutting the sprint to 3.1 seconds. The GT 55 and GT 63 are expected to arrive in spring 2027, with high-end options such as carbon-ceramic brakes, special paints, and accent-colored forged wheels.
The electric GT SUV represents a major turning point for Mercedes-Benz and AMG. After the EQ line failed to fully capture the brand’s performance image, AMG is taking a more independent path, building high-performance electric vehicles at its historic Sindelfingen facility. Although challenges remain around luxury EV values and charging infrastructure, the GT SUV is an unmistakable statement: Affalterbach’s appetite for extreme performance has not disappeared—it has simply gone electric.
