Mercedes-AMG reveals electric GT SUV with up to 860kW, Australian arrival expected in late 2027

The reveal and what it means for Australia

Mercedes-AMG has revealed its first dedicated electric SUV, the 2027 GT SUV, positioning it as a high-performance rival to the Porsche Cayenne Electric. As reported by Cars24, Mercedes-Benz Australia is expected to introduce the flagship GT63 first, with an anticipated local arrival in late 2027 — though Australian pricing and full specifications have not yet been confirmed. ¹

Chasing Cars reports that Mercedes-Benz Australia has yet to confirm timing and pricing for either the electric AMG GT coupe or the SUV, so no firm local launch date should yet be treated as locked in. The GT SUV follows the Mercedes-AMG GT 4-Door Coupe, which Cars24 notes is scheduled to reach Australia in March 2027. ²¹

The launch lands as Mercedes-Benz reports growing appetite for its electric models. According to Yahoo Finance, the company recorded 68,400 battery-electric car sales in the third quarter — a record, and up 61 per cent from a year earlier. ³

Performance: tri-motor flagship targets the Cayenne Turbo Electric

The range-topping GT63 uses three electric motors — two driving the rear wheels and one on the front axle — for a claimed peak output of 860kW and 2000Nm, with continuous power rated at 530kW, according to Cars24. Mercedes-AMG claims 0-100km/h in 2.7 seconds and 0-200km/h in 7.2 seconds, with top speed rising to 270km/h only when the optional Driver's Package is fitted. Chasing Cars reports the same figures, noting the AMG edges out Porsche's 850kW Cayenne Turbo Electric on the 0-200km/h sprint (7.2 versus 7.4 seconds) and top speed, although the Porsche claims the quicker 0-100km/h time of 2.5 seconds. ²¹

Cars24 details the role of the front motor on the tri-motor models: it acts as a booster, engaging when additional power or traction is required and helping to recover energy during deceleration. ¹

Below the flagship, the GT55 retains the three-motor layout but peaks at a claimed 600kW and 1860Nm, with 0-100km/h in a claimed 3.1 seconds and a 270km/h top speed, per Cars24. An entry-level dual-motor GT53 — producing 400kW and 800Nm with a 4.2-second 0-100km/h claim — is planned for overseas markets, but its Australian availability has not been confirmed. Yahoo Finance, citing reports at the time of the unveiling, listed the lineup in horsepower terms: up to 1153hp for the GT63, 805hp for the GT55 and 536hp for the GT53. ¹²³

The GT55 and GT63 use two axial-flux motors at the rear and one at the front, bringing rear torque vectoring and fully variable all-wheel drive, Chasing Cars reports. The entry GT53 pairs one motor on each axle and mimics the sound of an AMG six-cylinder engine, while the 55 and 63 replicate a V8 soundtrack with simulated gearshifts and haptic seat feedback through the AMGForce system. ²¹

Platform, dimensions and equipment

The GT SUV is the second vehicle on the dedicated 800V AMG.EA electric platform, sharing much with the GT 4-Door Coupe revealed earlier in the year. CarExpert reports the SUV measures 5084mm long, 2001mm wide and 1656mm tall on a 3040mm wheelbase — 245mm taller and 42mm wider than its sedan sibling. Under the VDA standard, boot space grows from 415L to 607L, and the frunk increases from 41L to 78L. Cars24 characterises it as a five-seat performance model sized between the GLE and GLS in Mercedes-Benz's SUV range. ⁴¹

Styling closely mirrors the GT 4-Door Coupe. CarExpert describes a similar open-mouth grille — purely ornamental gloss black plastic with eight vertical bars and a large three-pointed star — both of which can be illuminated as part of an optional package, along with six turbine-inspired tail-lights set into a field of black plastic. ⁴

Chassis technology includes three-stage-adjustable air suspension with adaptive dampers and rear-wheel steering. Chasing Cars reports that AMG Active Ride Control — automatic pitch and roll stabilisation claimed to reduce dive under braking and lift under acceleration — is standard on the 63 and optional on the 55, while Cars24 adds that carbon-ceramic brakes are standard on the GT63 and that a hydraulic system helps limit body roll and nose-dive. ²¹

The GT55 and GT63 also feature an intelligent aero system, according to CarExpert, which includes a self-deploying rear wing but in most situations reduces drag by closing off cooling inlets. ⁴

Inside, CarExpert describes a dashboard lifted largely from the GT 4-Door Coupe, with a 14-inch central touchscreen angled towards the driver, a 10.2-inch instrument display behind the wheel and an optional 14-inch passenger screen. The GT55 and GT63 add a Race Engineer Control Unit of three rotary dials governing motor responsiveness, nine levels of traction control and an Agility Control knob spanning understeer to controlled oversteer. Cars24 also lists seven drive modes including launch control, a drag-racing profile and drift mode, plus optional AMG Performance bucket seats and a Burmester 4D sound system. ⁴¹

Batteries, range and charging

GT55 and GT63 buyers can choose between a 106kWh and a 128kWh (useable) battery, both on the 800V electrical architecture with 11kW AC charging. Cars24 reports the 106kWh pack delivers a claimed WLTP range of 525km to 585km in the GT63 depending on configuration, rising to between 620km and 700km claimed with the larger 128kWh pack, which is exclusive to the SUV. ¹²

Charging claims differ in basis between reports and should not be conflated. Chasing Cars, citing manufacturer figures, says the smaller battery offers 600kW DC charging with the potential to add 380km of WLTP range in 10 minutes, while the larger battery supports up to 710kW and claimed adds of up to 450km in 10 minutes. Cars24 instead quotes 10 to 80 per cent charging times of 11 minutes (106kWh, at up to 600kW) and 12 minutes (128kWh, up to 710kW). Both outlets' figures are manufacturer claims dependent on compatible hardware. ²¹

CarExpert separately lists WLTP range figures of 597km for the GT53 and 525km or 620km for the GT55 and GT63 depending on battery, with kerb weight between 2525kg and 2715kg depending on specification. The publication notes the SUV is roughly 0.3 seconds slower to 100km/h than the equivalent sedan and gives up about 70km of range in 106kWh form, reflecting its higher drag rating of 0.27 versus 0.24. Cars24 cautions that the SUV's maximum charging rates exceed the fastest publicly available chargers in Australia, rated at up to 500kW. ⁴¹

Pricing and availability

European pricing opens at €113,050 (approximately A$183,000) for the entry GT53, which Chasing Cars reports will be the first variant on sale, arriving in late October in Europe. CarExpert confirms the same starting price in Germany and says the GT53 will be the first to come down the production line in Sindelfingen. Pricing for the GT63 and GT55 has not yet been announced; Chasing Cars reports the pair is due in European showrooms from around March 2027, while CarExpert says the GT55 and GT63 become available in Europe from the second quarter of 2027. ²⁴³

For Australia, Cars24 reports that Mercedes-Benz Australia is expected to introduce the GT63 first, with local pricing yet to be announced, and that more details are expected closer to the SUV's planned local launch in late 2027. The publication frames the likely competitive set around the Porsche Cayenne Turbo Electric, priced at $259,800 before on-road costs in Australia. Any comparison with the German list price should note the two figures are on different bases — a European manufacturer list price excluding on-road costs versus an Australian pre-on-road-cost figure for a rival. ¹²
