Developed from the ground up, the Mercedes-AMG GT SUV has made its global debut. We detail the Affalterbach marque’s new performance-focused EV, taking a closer look at powertrain options, performance, electric range, and more.
Mercedes-AMG GT SUV: Powertrain and performance
The first full-size SUV developed from the ground up by Mercedes-AMG, the GT SUV is available in three flavours: GT 53, GT 55, and GT 63.
The GT 53 is equipped with a duo of permanently excited synchronous electric motors — sited on the front and rear axles, respectively — producing combined power and torque outputs of 400 kW and 800 N.m. Power is delivered to the road via the German automaker’s 4Matic+ all-wheel-drive system. According to the Affalterbach brand, these figures allow the (2 525 kg, claimed) GT 53 to dispatch the 0-100 km/h dash in 4.2 seconds, before reaching the 200 km/h marker 10.4 seconds later, at 14.6 seconds. The GT 53 tops out at 250 km/h when specified with the Driver’s Package.
The GT 55 and GT 63 features three axial flux motors. The GT 55 is endowed with a combined system output of 600 kW and 1 860 N.m — good for a claimed 0-100 km/h sprint time of 3.1 seconds and 270 km/h top speed (when specified with the Driver’s Package). The GT 55 completes the 0-200 km/h run in a claimed 9.9 seconds.
Spearheading the three-strong lineup, the GT 63’s 860 kW and 2 000 N.m allow for claimed 0-100 and 0-200 km/h sprint times of 2.7 and 7.2 seconds, respectively. The pinnacle variant’s top speed matches the GT 55’s.
The GT SUV features seven AMG Dynamic Select driving modes: Comfort, Eco, Slipperiness, Individual, Sport, AMGFORCE Sport+, and Race. The latter programme further features Launch Control, Track Race, Drag Race, and Drift Mode.
The GT SUV is also equipped with the company’s new AMG Active Ride Control+ suspension setup featuring active pitch and roll stabilisation. Active rear-axle steering is also present.
Mercedes-AMG GT SUV: Battery, charging and range
The GT 53 features a 106 kWh (net) battery, which serves up a WLTP operating range of 597–668 km. The firm claims a combined energy consumption of 21.1–18.8 kWh/100 km. Thanks to 800 V electric architecture, the battery supports DC fast charging of up to 600 kW. At the maximum charging rate, the battery charges from 10-80% in 11 minutes, the manufacturer says, with a 10-minute charge adding 440 km of range.
The GT 55 and GT 63’s 128 kWh (net) battery supports DC fast charging of up to 710 kW, with a 10-80% charge taking 12 minutes. A 10-minute top up adds up to 454 km of range. The GT 55 and GT 63 offer a WLTP operating range of 620-700 km. The combined energy consumption is rated at 23.8-21.2 kWh/100 km.
Mercedes-AMG GT SUV: Dimensions and boot space
Following the new GT 4-Door Coupé, the GT SUV is the second model based on Mercedes-AMG’s AMG.EA platform. The SUV measures 5 084 mm in length and 2 001 mm in width. For reference, this makes it 147 mm longer and 2 mm wider than the GLE 63 S, of which the updated model was revealed in June 2026. The GT SUV stands 1 656 mm tall, with a 3 040 mm wheelbase. The boot capacity is rated at 607 litres, with an additional 78 litres of storage space available in the nose-located front luggage compartment.
