Mercedes-AMG GT SUV Goes Electric With Up to 1,169hp and 710kW Charging

• Mercedes-AMG’s first full-size SUV built entirely in-house is electric, with the top GT 63 quoting 1,169hp from three axial flux motors and both the GT 63 and the GT 55 due in spring 2027.
• Only the entry GT 53 SUV, at 544hp, is on order, from 113,050 euros as a German list price including 19 percent VAT, and the launch figures carry no pound price.
• Mercedes-AMG quotes 10 to 80 percent in up to 12 minutes on the 128 kWh battery, charging at up to 710 kW from an 800-volt charger, and calls its charging figures preliminary.

Only the Cheapest Mercedes-AMG GT SUV Is on Order, and Its Price Is in Euros

Mercedes-AMG put the GT 53 SUV on order from 20 October at 113,050 euros. That is a German recommended retail price and it includes 19 percent VAT, so it marks the scale of the money involved and says little about a bill in pounds. The GT 63 and GT 55 follow in spring 2027, and the launch figures carry no price for either.

Mercedes-Benz scheduled full UK pricing and specification for its UK website from 20 October. The international launch figures hold no pound price at all, and Mercedes-AMG says some features might not be available on UK cars. A driver planning a deposit should get the UK price and specification from a Mercedes-Benz dealer before reading anything into the euro figure.

The euro price does give one clean comparison. The GT 53 4-Door Coupe was priced from 115,430 euros for German sales starting 13 August, so the SUV sits 2,380 euros, or about 2 percent, below it. Both cars share a 400 kW (544hp) two-motor drivetrain, 800 Nm of torque and a 106 kWh battery. The SUV costs less, and the figures below show what it gives up in range and speed.

Three Versions, From 544hp to 1,169hp

The GT 63 sits at the top. Mercedes-AMG quotes a peak of 860 kW from three axial flux motors, which is 1,169hp in the maker’s metric figure, with 530 kW (721hp) as the continuous output and 2,000 Nm of torque. It lists 0 to 62mph in 2.7 seconds, or 2.5 seconds with a one-foot rollout that leaves the first 30.48 cm of travel out of the timing. The same car reaches 124mph in 7.2 seconds and carries a top speed of 168mph with the Driver’s Package. Boost lasts 63 seconds.

The GT 55 gives 600 kW (816hp), 1,860 Nm, 0 to 62mph in 3.1 seconds (2.8 seconds with rollout) and the same 168mph top speed. The GT 53, the only version on order, moves to two synchronous motors. Mercedes-AMG lists 400 kW (544hp) at peak, 270 kW (367hp) continuous, 800 Nm, 0 to 62mph in 4.2 seconds (3.8 seconds with rollout) and 155mph with the Driver’s Package. On the same measure the SUV trails its coupe sibling’s 3.9 seconds by 0.3 seconds.

In the GT 63 and GT 55 the rear axle holds two axial flux motors in a single housing, and the front axle carries a third that Mercedes-AMG calls a “booster motor”. It engages only when extra power or traction is needed, and a Disconnect Unit separates it under light load to cut drag. The GT 53 applies the same idea with a synchronous motor up front, then adds a two-speed transmission on the rear axle: a short first gear for pulling away and town driving, a taller second gear for the motorway.

The basic principle of the axial flux motor came from YASA, the British electric-motor specialist that became a wholly owned Mercedes-Benz AG subsidiary in July 2021. The same three-motor layout, at the same 1,169hp peak, is used in the electric GT 4-Door Coupe that Mercedes-AMG revealed in May.

What a 710kW Charge Means for Your Next Stop

Mercedes-AMG offers two 800-volt batteries: 106 kWh from 18 modules and 128 kWh from 22 modules. The GT 53 carries the smaller pack. For that car Mercedes-AMG quotes a peak of 600 kW, 10 to 80 percent in 11 minutes, 41 kWh in five minutes and 70 kWh in ten, worth 440 km (273 miles) of WLTP range. The 128 kWh pack in the GT 63 and GT 55 peaks at 710 kW and lists 10 to 80 percent in up to 12 minutes, 48 kWh in five minutes and 83 kWh in ten, worth up to 450 km (280 miles).

Fast charging has a price. Zapmap’s September index puts public rapid charger prices at an average of 79p per kWh. At that rate the GT 53’s 70 kWh ten-minute top-up costs £55.30, and the 83 kWh ten-minute top-up on the 128 kWh pack costs £65.57. Mercedes-AMG’s preliminary consumption for the GT 53 is 18.8 to 21.1 kWh per 100 km, or 30.3 to 34.0 kWh per 100 miles. That works out at 24p to 27p a mile on a 79p rapid charger and 8p to 9p a mile at Zapmap’s typical home rate of 26p per kWh. Both per-mile figures are calculations from the maker’s preliminary number, and no real-world cost has been measured.

The quoted peaks apply to an 800-volt charger rated that high. At 400-volt stations the car switches itself from 800-volt to 400-volt mode, and Mercedes-AMG says it is designed for five fast-charging standards worldwide, among them CCS2 for Europe. The maker labels its charging, consumption and energy figures preliminary: no confirmed values from an officially recognised testing organisation, EC type approval or certificate of conformity exist yet, and deviations are possible.

Range follows the pack. Mercedes-AMG lists WLTP ranges of 597 to 668 km (371 to 415 miles) for the GT 53, 525 to 585 km (326 to 363 miles) for the 106 kWh GT 63 and GT 55, and 620 to 700 km (385 to 435 miles) for the 128 kWh versions. The GT 53 4-Door Coupe lists 682 to 809 km (424 to 503 miles) from the same 106 kWh battery, so the SUV’s band sits 53 miles lower at the bottom and 88 miles lower at the top. The SUV is 242 mm taller than the coupe, listed from 2,525 kg against 2,375 kg, and its drag coefficient is 0.28 against 0.21. Real range depends on driving style, conditions, battery ageing, air conditioning, optional equipment, tyres, payload and route.

Jörg Burzer, Member of the Board of Management of Mercedes-Benz Group AG and Chief Technology Officer for Development and Procurement, makes the maker’s claim for the whole car: “We’re demonstrating that electric performance today no longer requires any compromises in sustained power, range or charging speed.” Every figure behind that claim stays preliminary until type approval.

Chassis, Steering and an Engine Note Built From Microphones

The headline suspension is AMG ACTIVE RIDE CONTROL+, standard on the GT 63 and optional on the GT 55, with no fitment listed for the GT 53. Active hydraulic elements replace conventional stabiliser bars and control pitch and roll, and Mercedes-AMG says they reduce front-end dive under braking and front-end lift under acceleration. Triple-stage air springs and an 8.2 litre pressure reservoir adjust ride height in near real time, including lowering with speed to cut drag.

Active rear-axle steering with up to 6 degrees of angle is standard. Below 80 km/h, about 50mph, the rear wheels turn against the front wheels, which shortens the wheelbase in effect and sharpens turning and everyday manoeuvring. Above that speed they turn up to 1 degree the same way as the front wheels for stability. Brakes are steel on the GT 53, steel on the GT 55 with carbon-ceramic as an option, and carbon-ceramic as standard on the GT 63.

The GT 63 and GT 55 add the AMG RACE ENGINEER, three rotary controls in the centre console. “Response Control” sets how sharply the motors answer the accelerator. “Agility Control” varies torque distribution from understeer to controlled oversteer, and “Traction Control” offers nine levels. The last two work only in RACE, AMGFORCE Sport+ or Sport with ESP switched off.

AMGFORCE Sport+ reproduces the sound of AMG V8 engines in the GT 63 and GT 55 and an AMG six-cylinder in the GT 53. Mercedes-AMG built it from over 100 measurements taken with 16 microphones, using reference cars such as the Mercedes-AMG GT R, and adds simulated gear changes, steering wheel paddles and seat shakers. A sound slider offers “Powerful”, “Balanced” and “Silent”. Stefan Weckbach, Chairman of the Management Board of Mercedes-AMG GmbH, sums the car up: “SUV by shape. GT by nature.”

Living With a 5.08 Metre Electric Performance SUV

The GT 53 is 5,080 mm long (200 inches, or 16 ft 8 in), 2,001 mm wide (78.8 inches) and 1,653 mm high (65.1 inches) on a 3,040 mm wheelbase. The GT 63 and GT 55 are 5,084 mm long and 1,656 mm high. The listed width is worth checking against a garage door and a parking bay before ordering anything.

Bastian Baudy, Chief Design Officer of Mercedes-Benz Group AG, describes the shape: “Its powerful appearance, with muscular shoulders, a wide track and a low-slung silhouette, makes its outstanding performance recognisable at first glance: pure AMG.” The practical side is a 607 litre boot by the VDA measure plus a 78 litre front boot, which is 192 litres and 37 litres more than the coupe’s 415 and 41 litres. A three-seat rear bench is standard, the backrests fold, and Mercedes-AMG describes generous headroom and legroom in the back.

Up front a 14.0 inch multimedia display angles toward the driver beside a 10.2 inch instrument cluster, and a 14 inch passenger display is optional. The “SKY CONTROL” panoramic roof switches between transparent and opaque. The new generation of MBUX software carries three AI agents: ChatGPT, Microsoft Bing and Google Gemini. With Mercedes-AMG warning that some features might not be available on UK cars, a buyer should ask the dealer which of these a UK car gets.

Three answers decide whether this SUV suits you: the UK price and specification, the type-approved WLTP and charging figures that replace today’s preliminary ones, and the timing for the GT 63 and GT 55, which Mercedes-AMG gives only as spring 2027.
