The Mercedes-AMG GT 4-Door Coupe has been revealed as the brand’s first bespoke electric performance car, with the flagship GT63 producing 860kW of power and 2000Nm of torque and capable of reaching a 300km/h top speed.
The GT63 and GT55 – the latter producing 600kW and 1800Nm – are the first models to use the company’s AMG.EA 800-volt electric architecture and axial-flux electric motors showcased by the GT XX concept.
The former can do the 0-100km/h sprint in 2.4 seconds, or just 2.1 seconds with a foot of rollout. The GT55 takes 2.8 seconds and 2.5 seconds respectively.
Due to enter production in mid-2026, Mercedes-Benz Australia has confirmed the GT will be sold locally, though arrival timing, pricing and equipment details are yet to be locked in.
In Australia, the previous GT63 S E Performance was priced from $409,600 before on-road costs in its final guise in 2025, powered by a 620kW twin-turbocharged 4.0-litre V8 plug-in hybrid powertrain.

The new-generation electric GT 4-Door Coupe takes over while bringing a simulated V8 soundscape – including artificial gearshift sounds – in a bid to win over die-hard petrol enthusiasts.
The new model measures 5094mm long, 1959mm wide and 1411mm tall, making it 46mm longer, 6mm wider and 42mm lower than its predecessor.
There are also shorter overhangs, while the EV’s 3040mm wheelbase extends beyond the previous model’s 2951mm. Despite the larger dimensions, kerb weight for both GT63 and GT55 variants increases by only 115kg to 2460kg.
Styling closely follows the GT XX concept, including aerodynamic aids and ‘air panels’ also seen on the SL range, helping deliver a claimed drag coefficient of 0.22. Key design cues include an illuminated front grille and twin ‘power domes’ on the bonnet.
At the rear are six circular tail-lights inspired by the GT XX concept, along with a large diffuser fed by two-stage underbody Venturi aero aids designed to increase high-speed downforce above 120km/h.
The package also includes an active rear spoiler which changes angle above 80km/h to alter downforce levels.
Underneath, the ‘skateboard’ chassis uses multi-link front and rear suspension with semi-active roll stabilisation, forged aluminium components and selected steel parts for added stiffness.
These are paired with all-wheel drive and rear-wheel steering systems already seen in Australian showroom models such as the latest AMG GT Coupe Pro.
The electric motors are housed within an aluminium casing, with two motors on the rear axle and one up front – all advanced axial-flux units.
Mercedes-Benz has been developing axial-flux motor technology for more than a decade in partnership with YASA, with the setup first previewed in the record-setting GT XX concept.
The three axial motors are designed with a more compact, lighter ‘sandwich’ layout to improve packaging efficiency.
Mercedes-Benz claims more than 35 world-first manufacturing techniques were required to produce the motors, which will be built at the company’s Berlin plant in Germany.
The new GT uses individually cooled cylindrical battery cells using a new lithium-ion chemistry designed to maximise packaging efficiency.
Advanced cooling systems for the batteries, motors and transmission also cool a pair of silicon-carbide inverters.
Mercedes-AMG claims a WLTP driving range of up to 696km for the GT63 and up to 700km for the GT55, while 600kW DC fast charging can replenish the 106kWh battery from 10 to 80 per cent in around 11 minutes, adding more than 460km of range.
Combined with regenerative braking, the cooling systems are designed to maintain peak performance for longer periods, with AMG targeting strong “continuous power density” for repeated high-load driving.
The GT63’s claimed 2.1-second 0-100km/h time is 0.8 seconds quicker than the PHEV model it replaces, while 0-200km/h takes 6.4 seconds.
Its 300km/h top speed is only available with the optional Driver’s Package and is 16km/h lower than the outgoing PHEV’s claimed maximum velocity.
Inside, seven drive modes are selectable via haptic controls on the AMG Performance steering wheel. Pulling the steering wheel paddles also unlocks a temporary 110kW boost in the GT63 and a 50kW boost in the GT55.
The cabin features a 10.2-inch digital instrument cluster flowing into a 14.0-inch central touchscreen, while the front passenger also gets a 14.0-inch display, all running the latest MBUX operating system.
There’s also a ‘Predictive Performance Manager’ featuring ‘Endurance’ and ‘Hotlap’ modes which automatically distribute power and energy to optimise racetrack lap times.
The GT63 cabin includes available race seats trimmed in leather and microfibre, while the rear bucket seats – featuring new ‘foot garages’ to improve passenger space – can optionally be replaced by a three-seat bench.
A panoramic sunroof and ambient lighting are standard, while a Burmester High End 4D audio system with stainless-steel speaker grilles is optional.
Mercedes-Benz plans to build several additional models on the AMG.EA platform, including future AMG sports cars with different body styles enabled by flexible battery packaging.
