Mercedes-AMG has officially revealed its new GT SUV, which is an all-electric performance flagship large SUV capable of producing up to 860kW and accelerating from 0-100km/h in just 2.7 seconds, yet also offering up to 700km of driving range. It’s confirmed for an Australian release in the second half of 2027.

The new GT SUV is the first SUV developed from the ground up entirely in-house by Mercedes-AMG in its 59-year history, rather than being based on an existing Mercedes-Benz model. It is also the second vehicle to use the brand’s dedicated ‘AMG.EA’ electric architecture, following the new AMG GT 4-Door Coupe.

Three variants will be offered globally: the ‘entry’ GT 53, mid-spec GT 55 and flagship GT 63, with outputs ranging from 400kW to an extraordinary 860kW. All three models feature all-wheel drive, while the two more powerful versions use three axial flux electric motors, including two driving the rear wheels.

The flagship GT 63 produces 860kW and a massive 2000Nm of torque, allowing it to reach 100km/h in 2.7 seconds from a standstill (or 2.5 seconds using the a one-foot rollout). It can also reach 200km/h in just 7.2 seconds and has a top speed of 270km/h with the optional Driver’s Package.

The mid-range GT 55 produces 600kW and 1860Nm, completing the 0–100km/h sprint in 3.1 seconds, while the entry-level GT 53 uses two conventional electric motors producing 400kW and 800Nm, achieving the same sprint in 4.2 seconds.

Two battery sizes are available, with usable capacities of 106kWh and 128kWh. Both use the same 800-volt electrical architecture and Formula 1-inspired cooling technology as the AMG GT 4-Door Coupe, with peak DC fast charging of up to 710kW. According to AMG, that can add 450km of driving range in just 10 minutes while delivering a 10-80 per cent charge in as little as 12 minutes in ideal conditions.

The larger battery enables a claimed WLTP driving range of up to 700km, while the smaller unit offers up to 585km in the GT 55 and GT 63. The GT 53, which uses the smaller battery exclusively, offers up to 668km.

Beyond performance, the GT SUV introduces a new ‘AMG Active Ride Control+’ suspension system, while rear-wheel steering is also standard and the flagship GT 63 receives carbon ceramic brakes.

As we saw in our preview ride from Monterey Car Week earlier this year, Mercedes-AMG has also developed a new ‘AMGFORCE Sport+’ system that reproduces the sound of a V8 engine in the GT 55 and GT 63, or a six-cylinder engine in the GT 53, using recordings of genuine AMG engines. The system also introduces simulated gear changes, steering-wheel paddle shifting and even seat vibrations to make the electric driving experience feel more like a traditional AMG.

Visually, the GT SUV adopts a low, wide stance like the AMG GT 4-Door Coupe with muscular wheel arches, frameless side windows and an aggressive front-end design. At 5084mm long and 2001mm wide, it’s a large SUV, although its low roofline gives it a sportier appearance than a conventional large luxury SUV.

Inside, a driver-focused cockpit features a 10.2-inch digital instrument cluster and 14-inch central touchscreen, with an additional 14-inch passenger display also available. The latest MBUX infotainment system includes AI-powered voice assistance, while the centre console of the GT 55 and GT 63 features three rotary controls for adjusting throttle response, cornering behaviour and traction.

Despite its performance focus, the GT SUV offers seating for five, a large 607-litre boot that expands to 1740 litres with the rear seats folded, and additional storage beneath the bonnet.

The Mercedes-AMG GT SUV will be produced at the company’s Sindelfingen factory in Germany, with European orders for the GT 53 opening on October 20, priced from €113,050 (approximately A$185,000 at current exchange rates). The GT 55 and GT 63 will follow in the European spring of 2027, while the Australian range has been confirmed for release in the second half of 2027.
