Key highlights
- Mercedes-Benz Australia will initially offer the GT63, with local pricing and full specifications yet to be confirmed.
- The flagship GT63 produces up to 860kW and 2000Nm, with a claimed 0-100km/h time of 2.7 seconds.
- Buyers can choose between 106kWh and 128kWh batteries, with the larger pack offering up to 700km of claimed WLTP range.
Mercedes-AMG has revealed its first standalone SUV, the all-electric 2027 AMG GT SUV, ahead of an expected Australian arrival in late 2027.
Positioned as a high-performance rival to the Porsche Cayenne Electric, the new SUV follows the Mercedes-AMG GT 4-Door Coupe, which is scheduled to reach Australia in March 2027.
Mercedes-Benz Australia is expected to introduce the GT63 first. Local pricing has not been announced, although the electric SUV is likely to compete with the Porsche Cayenne Turbo Electric, which is priced at $259,800 before on-road costs.
Measuring 5084mm long, 2001mm wide and 1656mm tall, the GT SUV sits between the GLE and GLS in Mercedes-Benz’s broader SUV range. However, it is a five-seat performance model designed around driving ability rather than maximum passenger space.

Up to 860kW from three electric motors
The range-topping GT63 uses three electric motors, with two driving the rear wheels and one powering the front axle. Together, they produce a claimed peak output of 860kW and 2000Nm, while continuous power is rated at 530kW.
Mercedes-AMG claims the GT63 can accelerate from 0-100km/h in 2.7 seconds and reach 200km/h in 7.2 seconds. Its top speed rises to 270km/h when equipped with the optional Driver’s Package.
That makes it more powerful than the Porsche Cayenne Turbo Electric, which produces 850kW. However, the Porsche is quicker to 100km/h, with a claimed time of 2.5 seconds.
The front motor acts as a booster, engaging when additional power or traction is required and helping recover energy during deceleration.
Below the GT63 is the GT55, which uses the same three-motor arrangement but delivers peak outputs of 600kW and 1860Nm. Its claimed 0-100km/h time is 3.1 seconds, while the top speed remains 270km/h.
An entry-level dual-motor GT53 is also planned for overseas markets, producing up to 400kW and 800Nm. Its availability in Australia has not been confirmed.
Up to 700km of range and ultra-fast charging
The GT55 and GT63 offer a choice of two battery packs, both operating on an 800-volt electrical architecture.
The standard 106kWh battery delivers a claimed WLTP driving range of 525km to 585km in the GT63, depending on the vehicle’s configuration. Mercedes-AMG says it can charge from 10 to 80 per cent in 11 minutes when connected to a compatible charger supplying up to 600kW.
The larger 128kWh battery, exclusive to the SUV, increases the claimed range to between 620km and 700km. Its maximum DC charging rate rises to 710kW, although the 10 to 80 per cent charging time increases to 12 minutes.
These charging figures will be difficult to realise in Australia. The fastest publicly available electric-car chargers in the country are rated at up to 500kW, below the SUV’s maximum charging capability. Actual charging speeds will also depend on the charger and battery conditions.
Both battery options support 11kW AC charging.
Simulated V8 sounds and track-focused technology
Despite its electric powertrain, the GT SUV will offer artificial engine sounds and simulated gear changes through Mercedes-AMG’s AMGForce system.
The GT55 and GT63 replicate a V8-style soundtrack, while the overseas GT53 simulates a six-cylinder engine. The system is designed to give drivers more familiar performance-car feedback, even though the vehicle does not have a combustion engine.
The SUV also features adjustable air suspension with adaptive dampers, while the GT63 gets additional hydraulic technology designed to reduce body roll through corners and minimise nose-dive under braking. Rear-wheel steering is available, and carbon-ceramic brakes are standard on the GT63.
Drivers can select from seven modes, including Comfort, Sport, Sport+, Race, Slippery, Individual and Eco. Launch control, a drag-racing profile and drift mode are also included.
Inside, the cabin features a 14-inch central touchscreen and a 10.2-inch digital instrument display, with an optional 14-inch screen for the front passenger. Buyers can also specify AMG Performance bucket seats and a Burmester 4D sound system.
More details, including Australian pricing and specifications, are expected closer to the GT SUV’s planned local launch in late 2027.
