Mercedes-AMG Reveals GT SUV With 1,153 HP and 710 kW Charging Capability
The flagship GT 63 adds 83 kWh in ten minutes, while U.S. deliveries for all three trims begin in summer 2027.
Mercedes-Benz has unveiled the AMG GT SUV, a high-riding electric model featuring up to 1,153 horsepower and peak charging rates of 710 kW. The vehicle, which sits on the bespoke AMG.EA platform, is scheduled to reach U.S. dealerships in summer 2027 across three variants: the GT 53, GT 55, and GT 63.
What Happened
The AMG GT SUV introduces significant updates to charging infrastructure compatibility compared to its sedan sibling, the GT 4-Door. While the four-door model achieves a 10–80% charge in 11 minutes, the GT SUV requires 12 minutes for the same range on its higher-capacity battery. However, the SUV’s peak charging power rises to 710 kW, allowing the GT 55 and GT 63 models to add 83 kWh of energy in ten minutes at an average power of approximately 498 kW. Mercedes claims this electric heavyweight can add 48 kilowatt-hours of energy in five minutes.
The lineup consists of three distinct performance tiers. The entry-level GT 53 retains the four-door’s smaller battery and 600-kW peak charging capability, offering a 10–80% charge time of 11 minutes. Specifically, the GT 53 adds up to 41 kWh in five minutes or 70 kWh in ten minutes. The GT 55 and GT 63 utilize a larger 128 kWh usable battery, up from the four-door’s 106 kWh. All versions support NACS connectors in America, 11-kW AC charging, and automatic voltage switching to 400 volts for compatible DC stations.
Performance specifications vary by trim. The GT 53 uses two synchronous motors producing 536 peak horsepower and 590 lb-ft of torque, with an estimated 0–60 mph time of 4.1 seconds, 0–124 mph in 14.6 seconds, and a top speed of 143 mph. The GT 55 features three axial-flux motors delivering 805 peak horsepower and 1,372 lb-ft of torque, reducing the 0–60 mph sprint to 3 seconds, 0–124 mph to 9.9 seconds, and offering an optional 168-mph top speed (standard is 143 mph). The flagship GT 63 raises peak power to 1,153 horsepower and torque to 1,475 lb-ft, achieving a 0–60 mph time of 2.6 seconds, 0–124 mph in 7.2 seconds, and a standard top speed of 168 mph.
Why It Matters
The introduction of 710 kW peak charging capability places the AMG GT SUV among the fastest-charging production vehicles available, addressing one of the primary barriers to adoption for high-capacity EVs. By adding 83 kWh in ten minutes, the vehicle can recover a substantial portion of its WLTP-estimated 385–435 mile range during a brief stop, potentially mitigating range anxiety for long-distance luxury buyers.
The shift to NACS support in the U.S. market aligns AMG with the emerging industry standard for North American charging infrastructure, ensuring compatibility with Tesla Superchargers and other networks adopting the connector. Furthermore, the mechanical disconnect capability of the front motors across all variants aims to improve efficiency during highway cruising, a critical factor for maximizing range in heavy performance SUVs.
The pricing for the U.S. market remains unannounced, though German prices for the comparable GT 4-Door EV range from €115,430 for the GT 53 to €196,350 for the GT 63. The lack of confirmed U.S. pricing leaves ambiguity regarding how these extreme performance and charging metrics will translate into consumer cost.
The Bottom Line
Mercedes-AMG’s new GT SUV combines extreme performance with rapid charging capabilities, targeting a niche segment of buyers prioritizing both speed and convenience. With U.S. deliveries planned for summer 2027, the model will test consumer appetite for 1,153-horsepower electric SUVs that can recharge nearly 83 kWh in ten minutes.
