2027 Mercedes-AMG GT 4-Door Coupe revealed as monster EV super sedan

Mercedes-AMG has taken the wraps off a high-tech, high-power, electric four-door 'coupe' that reboots its V8 flagship liftback with “sprint performance over marathon distances”, via F1-derived 800-volt battery technology.

The new Mercedes-AMG GT 4-Door Coupe has a near-identical footprint to its six-cylinder and V8-powered predecessor, despite being an all-new car, and draws styling cues from the AMG Concept GT XX.

It produces as much as 860kW from three electric motors – two rear, one front – for a claimed zero to 100km/h acceleration time of 2.4 seconds, aided by synthesised gear shifts and V8 engine sounds akin to a Hyundai Ioniq 5 N.

The electric car is only 5 per cent heavier than the outgoing GT63 plug-in hybrid – which produced 620kW/900Nm from a 4.0-litre twin-turbo V8, electric motor and 6kWh battery – thanks to its advanced and lighter-weight electric architecture.

Australian showroom arrivals have been locked in, but timing is yet to be announced, as is pricing.

The design takes cues from the GT XX Concept, but incorporates the German brand’s new ‘monobrow’ LED signature and an illuminated AMG GT-style ‘Panamericana’ grille up front.

At the rear, the six ‘afterburner’ tail-lights now incorporate the Mercedes-Benz star logo, and the production car includes a rear window, unlike the concept or other low-drag luxury EVs like the Polestar 5.

Inside, the cabin uses a 14-inch driver-oriented central touchscreen that blends with a 10.2-inch digital instrument cluster. A second 14-inch display is included for the passenger.

The overall layout is aligned with other Mercedes-AMG products, complete with leather, carbon fibre and microfibre trims.

Adjustment dials feature on the steering wheel, along with three rotary controllers on the console to adjust performance characteristics (traction, response and agility) while on the move.

Rear seating is for two, but a three seater bench can be added as an option, and the panoramic glass roof has adjustable transparency settings for individual segments, complete with AMG-branded lighting.

The AMG GT 4-Door has been developed from the ground up as the performance division's first electric car, on a bespoke platfom.

In the top-specification GT 63 variant, outputs are claimed at up to 860kW and a staggering 2000Nm – two-kilonewtons – during launch control, or a "continuous output" of 530kW in regular driving.

It is thanks to three electric motors and a 106kWh battery pack good for 596km to 696km of claimed driving range in European WLTP testing.

The GT63 claims a 0-100km/h acceleration time of just 2.4 seconds, 0-200km/h in 6.8 seconds, and a top speed of 300km/h.

Opt for the drag-racing 'one-foot rollout' metric, where the first few metres of movement are subtracted from the acceleration times, and the 0-100km/h and 0-200km/h claims drop to 2.1sec and 6.4sec, respectively.

The ‘lesser’ GT 55 delivers a still-impressive 600kW/1800Nm peak output – or 375kW continuous – for 0-100km/h and 0-200km/h in 2.8sec and 9.0sec under regular timing conditions.

Claimed driving range creeps up to between 597km and 700km in WLTP testing, with energy consumption as low as 17.8kWh/100km.

The AMG GT 4-Door will be one of the world's fastest-charging electric cars, able to suck in up to 600kW for a claimed 10 to 80 per cent charge time of just 11 minutes on a plug able to deliver enough power.

This power and response is achieved by the utilisation of a trio of axial flux motors (two rear, one front), used for their lighter weight, better cooling and higher output capability, which is a first for any production electric vehicle.

The motors are high-revving – more than 15,000rpm at the front – and very compact, measuring just eight centimetres in width for each rear unit, and nine centimetres for the front.

All this performance is delivered through a pair of planetary gearboxes – one for each rear motor – along with a transmission connected to the front motor that can drive all four wheels.

For efficiency when cruising, the front motor is automatically decoupled, but can reconnect within milliseconds when required for performance or energy recuperation.

The battery is cutting-edge too, using directly-cooled cells to help with temperature distribution and performance under load, borrowing technology developed for the AMG One hybrid hypercar with experience from the Mercedes-AMG Formula One team.

Mercedes-AMG has opted for nickel-cobalt-manganese-aluminium (NCMA) battery chemistry, providing an energy density of more than 298Wh/kg, 15 per cent more than a Tesla Model 3 Performance battery.

The development of the drivetrain formed part of the AMG GT XX concept car (below), which managed to drive 40,000km in seven-and-a-half days (181 hours) at a sustained average speed of over 220km/h.

Stopping power comes from carbon-ceramic brake rotors up front, with traditional steel rotors at the rear.

Handling optimisation is managed by two active underbody 'venturi flow' plates, and an active rear diffuser and spoiler, all referred to by Mercedes-AMG as Aerokinetics.

It is combined with active roll stabilisation and adjustable air suspension that work in concert with the physical suspension architecture, as well as rear-axle steering for better stability at high speeds and agility in a performance environment.

A modern electric super sedan needs a few ‘PlayStation-esque’ party tricks too, offered by way of the AMG Race Engineer customised dynamics software, which allows drivers to dial in both hardware and software to suit their performance requirements.

There is also a simulated V8 soundtrack, designed to emulate the AMG GT R's 4.0-litre twin-turbo V8.

The soundtrack incorporates some 1600 sound files to mimic the V8’s performance in a dynamic manner, including idle ‘burbles’ and physical gear change sensations, akin to the N e-Shift program in the Hyundai Ioniq 5 N.

A Mercedes-Benz Australia spokesperson told Drive that "the new GT 4-Door Coupe will come to Australia, timing is yet to be confirmed."

Pricing has not been announced for any market, but is said to be based on comparable predecessor vehicles. The outgoing Mercedes-AMG GT 4-Door was priced from $409,600 before options and on-road costs.
