Mercedes-AMG GT SUV surprises with 860 kW and 710 kW fast charging
1/67
Mercedes-AMG has unveiled the GT SUV, its first SUV developed entirely in-house, with the range-topping version delivering up to 860 kW to the wheels. The three-motor giant accelerates to 100 km/h in 2.7 seconds, while offering a 607-litre boot and a range of up to 700 km. Prices in Germany start at €113,050.
According to Mercedes-AMG's official press release, the new GT SUV uses the AMG.EA platform, designed specifically for high-performance electric cars and also underpinning the four-door AMG GT. Unlike previous AMG SUVs, the engineers did not adapt an existing Mercedes model, instead developing the entire car from scratch.
Three motors and sports car acceleration
Mercedes-AMG offers the new SUV in three power levels. The entry-level GT 53 uses two electric motors with a combined output of 400 kW, the GT 55 has three motors producing 600 kW, and the flagship GT 63 develops as much as 860 kW. The latter reaches 100 km/h in 2.7 seconds without the so-called one-foot rollout allowance. With the optional Driver's Package, top speed reaches 270 km/h.
The GT 55 and GT 63 use compact axial-flux motors whose high power density enables exceptional performance. The battery's directly cooled cylindrical cells help prevent overheating and maintain a continuous output of up to 530 kW. This is an important advantage when many electric sports cars can sustain their peak output only briefly.
710 kW charging and a 700 km range
The 800-volt electrical system supports batteries with capacities of 106 or 128 kWh. The smaller battery supports DC charging at up to 600 kW, while the larger one can accept as much as 710 kW.
In ideal conditions, the larger battery can charge from 10 to 80 per cent in just 12 minutes. A ten-minute charging stop can add up to 450 km of WLTP range. These figures, however, require exceptionally powerful charging infrastructure, which remains scarce across Europe's public charging networks.
Sports car technology, family car practicality
At approximately 5.08 metres long, the GT SUV offers a 607-litre boot, expanding to 1,740 litres with the rear seats folded. An additional storage compartment at the front has a capacity of 78 litres measured to the VDA standard.
The GT 55 and GT 63 get AMG Active Ride Control+ active suspension, which hydraulically controls body roll and pitch. Together with rear-wheel steering and all-wheel drive with variable torque distribution, this should help disguise the large electric car's weight.
The AMG GT SUV will compete with the Porsche Cayenne Electric and Lotus Eletre in the European market. Mercedes' main strength, however, is not power alone, but the combination of a large battery, exceptionally fast charging and a practical body.
Orders for the GT 53 open in Germany on 20 October, with prices starting at €113,050. The more powerful GT 55 and GT 63 go on sale in spring 2027.
AMG's real challenge now is to prove that an electric SUV weighing almost 2.7 tonnes can deliver a driving experience as convincing as that of the brand's traditional sports cars.
