New 860kW super SUV confirmed
By John Mahoney · 19 Oct 2026
The new 860kW all-electric Mercedes-AMG GT SUV has usurped the Porsche Cayenne Turbo to become the most powerful SUV ever sold in Australia when makes its debut in late 2027 priced from around $260,000 plus on-roads. Arriving just months after the AMG GT 4-Door Coupé touches down (March), the new higher-riding AMG shares the sedan's outrageous triple-motor powertrain and produces an identical 860kW and 2000Nm of torque. Off the line, the AMG GT SUV launches from 0-100km/h sprint of 2.7 seconds and has a 270km/h top speed. Despite its epic output, those blistering performance figures trail rivals like the 850kW Porsche Cayenne Turbo ($259,900) and the 772kW Ferrari Luce ($991,446) that both take a supercar-humbling 2.5 seconds for the 0-100km/h dash, with the Prancing Horse's controversy-courting EV even topping out at a much higher 310km/h. Sharing slightly toned-down design cues with the sedan, the latest AMG GT SUV owes much to the earlier 2022 Vision AMG and last year's GT XX. Like the lower sedan, the AMG GT is the second car to sit on the all-new AMG.EA architecture that allows it to embed the German performance sub-brand's next-generation powertrain technology. Measuring 5084mm long, 2001mm wide and standing 1656mm tall, with a stretched 3040mm wheelbase, the AMG GT SUV is 99mm longer, 21mm broader but 188mm lower than the battery-powered Cayenne wagon it competes with. On the scales AMG's new flagship EV weighs in at 2585kg, which sounds heavy but is 60kg lighter than the Porsche, provided you skip heavy options. The star feature of the AMG GT SUV, like its sibling, is its next-generation powertrain that has been developed with British-based, Mercedes-Benz-owned Yasa, with the SUV packing not one, but three of its pancake-shaped axial-flux motors. Two discus-shaped e-motors that are each 80mm wide drive the rear axle, while a thicker 90mm motor spins up the front wheels. Paired with single-speed transmissions, the triple motors are fed current by a 106kWh (useable) battery that provides for a range of up to 585km on the WLTP test cycle. If you regularly travel further than that, a more energy-dense 128kWh battery is also available that increases the WLTP cruising range to around 700km. The respectable range is combined with 800-volt electrics that provides for ultra-fast DC charging of up to 600kW - 200kW more than a Porsche Cayenne, with a 10 to 80 per cent top-up taking an unbelievably brisk 11 minutes. The catch is finding (and being close to) one of Australia's few megawatt chargers that should have opened by the time the SUV launches. With the bigger 128kWh battery, charging ramps up to 710kW, adding as much as 450km of range in just 10 minutes, although the 10 to 80 per cent refill is a minute longer at 12 minutes. AC charging, meanwhile, is limited to 11kW, with a 22kW charger likely to be added later. Two further powertrains might be on the menu to arrive in Australia later – a triple-motor AMG GT 55 (600kW/1860Nm) and the base AMG GT 53 (400kW/800Nm) that is driven by two conventional e-motors. Coming with the 106kWh power pack, the lesser AMG GT SUV variants have a range of between 668-700km, depending on the wheel/tyre package. Helping it defy physics, the AMG GT gains Benz's latest AMG Active Ride Control+ trick suspension that cancels out body roll while cornering and helps dial back the pitch and dive associated with strong acceleration and braking the Mercedes-AMG is capable of. Enhancing agility is a new rear-wheel steering that pivot the rear wheels up to 6 degrees. Top-of-the-range AMG GT 63 SUVs in Australia will be offered with standard carbon-ceramic brakes on both axles are standard. While others are experimenting with dystopian soundscapes, the AMG GT 63 is said to faithfully reproduce the sound of a proper V8, with it able to mimic Benz icons of the past like the old AMG GT R. For those not in the mood, a quieter 'Balanced' or even 'Silent' soundtrack is also available. Like the sedan, the AMG GT SUV comes with simulated gearshifts via steering wheel paddles. Customised driver displays as well as integrated seat shakers all add to the immersive experience. An AMG Race Engineer feature has been added that, via three rotary controllers in the centre console, allowing you to sharpen or dull the throttle or tweak torque vectoring or the amount of power being sent to the rear wheels. No less than nine levels of traction control intervention and seven driving modes are available, as well as the opportunity to turn off the ESP system completely. Featuring powerdomes, flared arches and oversized wheels, the AMG GT SUV is claimed to reference past AMG models, but the new car gains some trick active aero to keep it stable at high speeds. These include a pop-up roof spoiler that switches to a low-drag position at speeds above 150km/h. If it detects you're pushing hard on your favourite road and it switches to its steepest angle for maximum downforce to enhance traction. Vertical slats in the bumper, meanwhile, remain closed to minimise drag but open when the e-motor and battery need extra cooling. Inside, you sit low for an SUV to create a sportier driving position. Ahead of a driver is a 10.2-inch digital cluster, plus a large 14.0-inch infotainment that is angled towards the driver. A second 14-inch display is available for the passenger. All the tech runs the brand's newest MB.OS software which, as well as three AI assistants (ChatGPT, Bing, Gemini) also offers an AMG Performance menu that shows the active aero working, broadcasts the energy flowing from axle to axle and even shows you how to bring the tyres and brakes up to their optimum temperatures on track. Once ready, there's then a digital lap timer designed by IWC. If you need help finding a corner's apex, there's also the AMG Track Pace that's claimed to be akin to having a professional coach onboard. Augmented reality then superimposes the racing line from saved laps to help you nail the perfect lap. Bolting the driver and co-pilot in place are heavily bolstered AMG Performance bucket seats that are combined with a pair of big AMG Performance steering wheel paddles. Despite a rakish silhouette, the AMG GT SUV gets rear seats that offer decent head- and legroom, while a full-width panoramic roof bathes the cabin in light and can switch to opaque at the switch of a button. Since many will expect it to play the family wagon, as well as plenty of space within, there is a decent 607 litre boot, which expands to 1740 litres with the second row folded. Up front, there's even a respectable 78-litre frunk to stow cables. Available in up to 60 Manufaktur hues, special finishes apply to colour accents for the forged alloy wheels and even the seatbelts for those who love the idea of planning to making their AMG GT SUV unique. Mercedes-Benz Australia says ahead of its launch in late 2027 it is too early for pricing and specification for the AMG GT 63, with an announcement expected closer to its debut, as well as an update on whether we'll also see the AMG GT 55 and the entry AMG GT 53.
