Mercedes-AMG GT SUV Targets 1,153 HP, 710 kW Charging in 2027

For US buyers, the electric Mercedes-AMG SUV promises striking power but charging at its fastest rate may be harder to find. Mercedes-AMG has unveiled the GT SUV, an all-electric performance vehicle with up to 1,153 hp and DC charging rated at up to 710 kW, according to Electrek.
The first units are expected at US dealerships in summer 2027. The launch lineup has three versions, with differences in motor setup, power, battery capacity and charging performance.
The GT 63 SUV and GT 55 SUV each use three axial-flux motors and have a peak output of 1,153 hp and 805 hp, respectively. The GT 53 SUV uses two conventional synchronous motors and is rated at 536 hp. Mercedes’ acceleration figures remain estimates, Electrek reported.
Fast charging is the headline figure. The two larger-battery versions can charge at up to 710 kW, while the GT 53 peaks at 600 kW.
Charging speed meets a US infrastructure limit
Electrek reported that Mercedes estimates a 10-to-80% charge in 12 minutes for the GT 63 and GT 55. The company says that can add up to 454 km (282 miles) of WLTP range in 10 minutes. The GT 53 is listed at 11 minutes for a 10-to-80% charge.
Those peak rates may not be readily available to US drivers. Electrek said many of the fastest public chargers in the country, including units being rolled out by IONNA, are rated at 400 kW. That leaves a gap between the SUV’s maximum charging capability and the equipment many drivers may encounter.
Mercedes lists NACS among the five charging standards supported by the GT SUV. Electrek said that should allow access to Superchargers, while charging close to 710 kW remains a separate challenge. The publication also reported that a 750 kW charger in the US pipeline had already slipped to next year.
The difference matters in practice: the advertised maximum alone does not determine how quickly a driver can recharge. Access to a compatible high-power charger will shape whether the SUV can deliver its shortest quoted charging times.
Three versions, different battery sizes
The GT 63 and GT 55 have a 128 kWh usable battery, while the GT 53 has a 106 kWh pack. Mercedes quotes WLTP ranges of 620 to 700 km (385 to 435 miles) for the two larger-battery models and 597 to 668 km (371 to 415 miles) for the GT 53. Electrek said US EPA range figures are expected to be lower.
The GT 63 is listed at 2,695 kg (5,942 lb), with a drag coefficient of 0.27. The top model’s peak output is 1,153 hp, but its continuous output is 711 hp, according to Electrek. The GT 55 also has 711 hp of continuous output; the GT 53 is listed at 362 hp.
Mercedes describes the GT SUV as the first full-size SUV it developed entirely on its own. It is the second vehicle on the company’s dedicated AMG.EA electric architecture, following the electric GT 4-Door Coupé, which Electrek said was revealed earlier this year.
The GT 63 and GT 55 use flat axial-flux motors. Electrek reported that Mercedes bought UK specialist YASA in 2021 and that the technology has also reached the AMG CLA 45. The battery cells use an NCMA cathode and silicon in the anode, and Mercedes claims more than 298 Wh/kg at cell level.
Inside, the five-seat SUV has a 14-inch central screen combined with a 10.2-inch driver display. An additional 14-inch passenger screen is optional. Cargo capacity is listed at 21.4 cubic feet behind the rear seats, with a 2.8-cubic-foot front trunk.
The GT 63 and GT 55 can play recorded V8 sounds in the AMGFORCE Sport+ setting, while the GT 53 uses a six-cylinder sound. Electrek reported that drivers can switch to a “Silent” setting. The GT 63 also includes AMG Active Ride Control+ as standard, while rear-axle steering of up to 6 degrees is standard across the lineup.
Electrek identified the Porsche Cayenne Turbo Electric as the GT SUV’s obvious target and said the two models’ acceleration figures are a dead heat.
