Mercedes-AMG Unveils GT SUV With 1,153 HP and 710 kW Charging
The all-electric performance SUV features a 128 kWh battery and ties the Porsche Cayenne Turbo Electric at 0-60 mph.
Mercedes-AMG has unveiled the GT SUV, an all-electric performance vehicle featuring up to 1,153 horsepower and DC fast charging capabilities of up to 710 kW. The first units are expected to reach US dealerships in summer 2027.
What Happened
The GT SUV is AMG’s first full-size SUV developed entirely in-house and the second model built on the dedicated AMG.EA electric architecture. Mercedes-Benz is launching three versions in the US: the AMG GT 63 SUV, AMG GT 55 SUV, and AMG GT 53 SUV. The top-tier GT 63 features three axial-flux motors delivering 1,153 hp peak power and 1,475 lb-ft of torque, with an estimated 0-60 mph time of 2.6 seconds (2.4 seconds with one-foot rollout). The GT 55 uses three axial-flux motors for 805 hp, while the entry-level GT 53 utilizes two conventional synchronous motors for 536 hp.
The GT 63 and GT 55 models are equipped with a 128 kWh (usable) 800-volt battery pack using tall, narrow cylindrical cells with an NCMA cathode and silicon anode. The GT 53 has a smaller 106 kWh pack. Mercedes claims the cell-level energy density exceeds 298 Wh/kg, with cells cooled by non-conductive oil. The larger battery variants support DC fast charging at up to 710 kW, allowing a 10-80% charge in 12 minutes. The GT 53 peaks at 600 kW, achieving a 10-80% charge in 11 minutes. WLTP range estimates are 620 to 700 km (385 to 435 miles) for the GT 63 and GT 55, and 597 to 668 km (371 to 415 miles) for the GT 53. The GT 63 weighs 2,695 kg (5,942 lb) and has a drag coefficient of 0.27.
The vehicle also features a simulated V8 sound via the AMGFORCE Sport+ setting on the GT 63 and GT 55, along with rear-axle steering of up to 6 degrees and a 14-inch central screen. Pricing has not yet been announced.
Why It Matters
The GT SUV positions itself directly against the Porsche Cayenne Turbo Electric. On paper, the two vehicles tie at 2.4 seconds for 0-60 mph (with rollout). However, the Mercedes offers a larger 128 kWh battery compared to the Porsche’s 113 kWh and supports significantly faster charging at 710 kW versus the Porsche’s 400 kW. This competitive advantage in battery capacity and charging speed is central to the vehicle's positioning, even as its 710 kW capability exceeds most current US public infrastructure.
The Bottom Line
Mercedes-AMG’s GT SUV enters the luxury EV market with superior charging specs and battery capacity compared to its main rival, the Porsche Cayenne Turbo Electric. As a halo product with unannounced pricing and delivery dates in summer 2027, it aims to leverage its technical specifications to capture a niche segment of high-performance EV buyers.
