Electric Mercedes-AMG GT SUV unveiled with 1,153 hp and 710 kW charging

Mercedes-AMG expanded its electric vehicle lineup by unveiling the all-electric Mercedes-AMG GT SUV on Saturday, 17 October 2026. According to EVXL and UA.NEWS, this vehicle represents the first full-size SUV developed entirely in-house by the Affalterbach performance division. Built on the dedicated AMG.EA platform following the earlier electric GT 4-Door Coupé, the flagship model is positioned as an answer to the Porsche Cayenne Electric, as reported by Electrek.

The lineup spans three distinct versions: the GT 53, the GT 55, and the range-topping GT 63. Under the skin, the GT 55 and GT 63 utilize three axial-flux motors—one on the front axle and two at the rear—supplied by UK specialist YASA, which Mercedes acquired in 2021, according to Electrek. These flat, pancake-shaped motors offer higher power density relative to their weight than conventional radial-flux designs. Meanwhile, the entry-level GT 53 relies on two synchronous motors paired with a two-speed rear transmission, as reported by Autos.

Performance metrics vary across the variants. The GT 63 generates a peak output of 1,153 horsepower and 1,475 lb-ft of torque, with a continuous output rating of 711 horsepower and a 63-second boost window. According to Evxl, the GT 63 accelerates from 0 to 60 mph in an estimated 2.4 seconds using a one-foot rollout, or 2.6 seconds without it, reaching an electronically limited top speed of 168 mph. The GT 55 matches the flagship's continuous power and battery size while delivering a peak of 805 horsepower. The GT 53 produces a peak of 536 horsepower and a continuous 362 horsepower, achieving a 0-to-60 mph sprint in 4.1 seconds.

Powering the higher trims is a 128 kWh usable 800-volt battery pack utilizing tall, narrow cylindrical cells with an NCMA cathode and silicon in the anode. According to Electrek, each cell is directly immersed in non-conductive oil for thermal management, a cooling strategy that supports both high continuous power delivery and rapid energy replenishment. The GT 53 uses a smaller 106 kWh battery pack.

The charging specifications represent a notable leap for a legacy automaker, though practical utilization depends heavily on external infrastructure. The GT 63 and GT 55 support DC fast charging at up to 710 kW, which Mercedes states can achieve a 10 to 80 percent charge in 12 minutes and add up to 282 miles of WLTP range in 10 minutes. The GT 53 caps its charging intake at 600 kW, completing the 10 to 80 percent charge in 11 minutes. However, Electrek notes that most public fast chargers in the United States, such as those deployed by IONNA, are currently rated for 400 kW, meaning owners will primarily be paying for headroom on future high-output infrastructure. The vehicle supports five DC plug standards, including NACS for Tesla Supercharger compatibility, and automatically switches to 400-volt mode at older stations.

Weight management and handling features are addressed through dedicated active chassis systems. The GT 63 features standard AMG Active Ride Control+, which replaces mechanical anti-roll bars with active hydraulics and air springs to control both roll and pitch, as detailed by Motorillustrated. All variants come equipped with rear-axle steering capable of up to six degrees of movement. Curb weight sits at 2,695 kg for the GT 63 and 2,715 kg for the GT 55, while the lighter GT 53 weighs 2,525 kg.

Inside, the cabin features a 14-inch central touchscreen merged with a 10.2-inch digital instrument cluster, alongside an optional 14-inch screen for the front passenger. Drawing inspiration from combustion performance models, the vehicle includes simulated exhaust notes through its AMGFORCE Sport+ drive program, playing recorded V8 sounds for the GT 63 and GT 55, and a six-cylinder simulation for the GT 53, paired with paddle-triggered virtual gearshifts and seat vibrations. Drivers can dial back the synthetic noise using a "Silent" setting, as reported by EVXL.

Following this introduction, Mercedes-AMG has scheduled the first vehicle deliveries to US dealerships for summer 2027. Official pricing and North American EPA range estimates remain unannounced. Additional specifications, including final market-specific pricing and regional showroom arrival dates, are expected to be disclosed in the coming weeks and months.
