Mercedes-AMG has unveiled the GT SUV, its first fully in-house electric performance SUV, arriving roughly two years before BMW is expected to apply its M badge to an all-electric X5. The new model sits on the AMG.EA platform, developed from the ground up for high-performance electric vehicles, and shares its design language, screen-heavy interior and hardware with the AMG GT 4-Door Coupe revealed earlier this year.
The GT SUV will launch in three versions: GT 53, GT 55 and GT 63. The entry-level GT 53 uses two synchronous electric motors, one on each axle, producing a combined 536 hp and 800 Nm of torque. The GT 55 steps up to three axial-flux electric motors delivering 805 hp and 1,860 Nm. At the top of the range, the GT 63 produces 1,153 hp and 2,000 Nm. Both higher-performance models use two rear-axle motors, allowing more precise torque distribution between the rear wheels.
Performance figures place the flagship firmly in supercar territory. The GT 63 sprints from 0 to 62 mph in as little as 2.7 seconds, reaches 124 mph in 6.8 seconds and is electronically limited to 168 mph when fitted with the optional Driver’s Package. Those numbers are achieved in a vehicle measuring more than five metres long and weighing up to 2,695 kg. Mercedes-AMG is also aiming for repeatable performance, fitting an 800-volt electrical architecture and a high-performance battery with cylindrical cells and direct oil cooling to avoid overheating after repeated launches.
Two usable battery capacities are offered: 106 kWh and 128 kWh. The smaller pack supports DC charging at up to 600 kW, while the larger battery raises the maximum to 710 kW. Under ideal conditions, the system can add up to 450 km of WLTP range in ten minutes, and a 10-to-80 per cent charge takes approximately 11 minutes with the smaller battery and 12 minutes with the larger one. The GT 63 offers a maximum WLTP range of up to 700 km, while the GT 53 can cover up to 668 km. Those charging figures depend on finding a compatible high-power station capable of delivering the advertised output, and 710-kW chargers remain rare.
To manage the SUV’s size and weight, Mercedes-AMG has developed a new suspension system with active pitch and roll stabilisation. Rather than relying solely on conventional anti-roll bars, the system uses active hydraulic elements to control body movements while balancing comfort and handling. Rear-wheel steering helps the GT SUV feel more agile than its dimensions suggest, while a fully variable all-wheel-drive system distributes torque between the axles as needed. The three-motor versions can also vary torque between the rear wheels to improve traction and cornering.
Aerodynamics play a role too. An active roof spoiler and adjustable aerodynamic elements manage airflow depending on speed and driving conditions, giving the body a drag coefficient of 0.27. The GT SUV measures 5,084 mm long, 2,001 mm wide and up to 1,656 mm tall, with a wheelbase of 3,040 mm.
For traditionalists, Mercedes-AMG has gone to considerable lengths to make the electric GT SUV sound and feel like a conventional performance car. The GT 55 and GT 63 offer a simulated V8 soundtrack, while the base GT 53 gets a synthetic six-cylinder sound. The package also includes simulated gear changes, steering-wheel paddles and seat vibrations, giving drivers more sensory feedback than a typical electric vehicle.
