Mercedes-AMG Unveils Electric GT SUV With 1,153 HP and 710 kW Charging

Mercedes-AMG unveiled an all-electric GT SUV on Saturday. The flagship GT 63 makes 1,153 horsepower and charges at up to 710 kilowatts.

Three versions reach U.S. dealerships next summer. The GT 63 tops the range with three axial-flux motors, 1,475 lb-ft of torque, and an estimated 0–60 mph time of 2.6 seconds. The GT 55 uses the same three-motor setup for 805 hp and a 3.0-second run. The entry GT 53 gets two conventional motors, 536 hp, and 4.1 seconds.

The charging numbers are the story. The GT 55 and GT 63 carry a 128-kWh usable battery pack and go from 10 to 80 percent in 12 minutes. Mercedes says they can add 454 km — about 282 miles — of range in 10 minutes. The GT 53's 106-kWh pack peaks at 600 kW and does 10–80 in 11 minutes.

There is a catch for U.S. buyers. Most of the fastest public chargers here top out at 400 kW; on those, Mercedes quotes a 16-minute 10–80 time. The SUV supports NACS, so Supercharger access should not be a problem — but charging anywhere near 710 kW will have to wait for next-generation stations.

The axial-flux motors are the key hardware. They are flat, pancake-shaped motors that deliver more power per pound than the radial-flux motors in most EVs. Mercedes bought British specialist YASA in 2021. The three-motor versions can mechanically disconnect the front motor to save energy; the GT 53 gets a two-speed rear gearbox instead.

This is the first full-size SUV AMG has developed entirely in-house in the brand's 59-year history. It is the second vehicle on AMG's dedicated AMG.EA electric architecture, after the GT 4-Door Coupe shown earlier this year, and it borrows that car's motors and battery.

Inside, there is a 14-inch central screen, a 10.2-inch driver display, and an optional second 14-inch screen for the passenger. Like the four-door, the SUV plays simulated engine sounds — a recorded V8 on the GT 63 and GT 55, a six-cylinder on the GT 53 — with a Silent mode to turn them off. Rear-axle steering is standard on all versions.

The obvious target is the Porsche Cayenne Electric. On paper, AMG edges it: the Cayenne Turbo Electric makes 1,139 hp and charges at 400 kW. Mercedes has not announced U.S. pricing; the Cayenne Turbo Electric starts at $163,000. In Germany, the GT 53 starts at €113,050.

Claimed WLTP range is 620 to 700 km for the GT 63 and GT 55, and 597 to 668 km for the GT 53. Expect lower EPA numbers. The GT 63 weighs 2,695 kg — just under 6,000 pounds.
