For the first time in its 59-year history, Mercedes-AMG is developing a full-size SUV entirely in-house and from the ground up. The GT SUV is the second model built on the AMG.EA high-performance electric architecture, following the AMG GT 4-Door Coupé.
It pairs the presence of a full-size SUV with a low, sporty seating position and a low centre of gravity. Lightweight construction and intelligent packaging provide weight advantages, and an interior sound system reproduces the sound of a V8 or six-cylinder engine.
Three Variants and a Staggered Launch
The range comprises the GT 63 SUV, GT 55 SUV and GT 53 SUV. The entry GT 53 opens for orders on October 20, starting at €113,050. The GT 63 and GT 55 follow in spring 2027.
Mercedes-Benz executives framed the car around the phrase “SUV by shape, GT by nature.” CTO Jörg Burzer said the axial flux motors and new high-voltage battery set a benchmark in electric SUVs, with no compromise on sustained power, range or charging speed. Stefan Weckbach, chairman of Mercedes-AMG GmbH, said the car combines the space and versatility of a full-size SUV with the emotional character of a genuine AMG. Bastian Baudy, chief design officer, said the muscular shoulders, wide track and low silhouette make its performance clear at a glance.
Drivetrains and Performance
The GT 63 and GT 55 use a High Performance Electric Drive Unit on each axle. The rear unit houses two axial flux motors with compact planetary gearboxes in one housing, while the front unit uses a single axial flux motor that acts as a booster and disconnects under light loads to cut drag.
The GT 63 produces up to 860 kW (1,169 hp), and the GT 55 up to 600 kW (816 hp). The GT 53 uses two synchronous motors, one per axle, for a combined 400 kW (544 hp), and a two-speed rear transmission with a short first gear for urban driving and a taller second gear for motorway cruising.
In the top variant the SUV reaches 100 km/h in 2.5 seconds and 200 km/h in 6.8 seconds, with a top speed of 270 km/h when the Driver’s Package is fitted.
Battery and Charging
The AMG High Performance Electric Battery runs at 800 volts and uses directly cooled cylindrical cells, each 105 mm tall and 26 mm in diameter, with a silicon-containing anode and an NCMA cathode delivering more than 298 Wh/kg. An electrically non-conductive oil flows around every cell. The pack comes in two sizes: 106 kWh with 18 modules and 128 kWh with 22 modules.
The 106 kWh version charges at up to 600 kW and adds up to 380 km of WLTP range in ten minutes. The 128 kWh version reaches 710 kW and adds up to 450 km in the same time, and the battery charges from 10 to 80 percent in up to 12 minutes. The larger pack is rated for up to 700 km of WLTP range. In regions with thin charging networks, the system switches automatically to 400-volt charging. The SUV supports CCS2, GB/T, CHAdeMO, CCS1 and NACS.
Chassis, Steering and Aerodynamics
The AMG ACTIVE RIDE CONTROL+ suspension replaces conventional anti-roll bars with active hydraulic elements that control pitch and roll, and it adds three-stage air springs and speed-dependent lowering. It is standard on the GT 63 and optional on the GT 55. Active rear-axle steering turns the rear wheels up to 6 degrees opposite the fronts below 80 km/h, and in the same direction above that speed.
The GT 63 comes standard with carbon-ceramic brakes, while the GT 55 offers them as an option and the GT 53 has steel brakes. An AMG Performance 4MATIC+ system distributes torque continuously between the axles, and on the GT 63 and GT 55 it also vectors torque between the rear wheels.
Aerodynamics are active. The AEROKINETICS Airpanel keeps the front slats closed to cut drag and opens them only when cooling demand rises. From 150 km/h the roof spoiler adjusts to balance drag and stability, and at its steepest angle it adds traction during dynamic driving.
Driving Modes, Sound and the AMG RACE ENGINEER
Seven AMG DYNAMIC SELECT modes range from Eco and Comfort to Sport, AMGFORCE Sport+, RACE, Slippery and Individual. RACE includes Drift Mode, Drag Race, Track Race and Launch Control. On the GT 63 and GT 55, three rotary controls in the centre console adjust response, agility and traction. The traction control setting has nine levels.
AMGFORCE Sport+ reproduces engine sound from more than 100 measurements made with 16 microphones on reference cars such as the Mercedes-AMG GT R, and it adapts in real time to the driver’s throttle inputs.
It simulates gear changes, provides paddle shifting and adds seat shakers. The Predictive Performance Manager, first used on the CONCEPT AMG GT XX’s record run, adjusts energy use section by section on the racetrack, conserving energy on downhill and tight sections for later use.
Cabin and Digital Features
The cockpit is built around a 14.0-inch multimedia display angled toward the driver and a 10.2-inch instrument cluster that visually form one unit, with a 14-inch passenger display available as an option.
The panoramic SKY CONTROL roof can switch between clear and opaque. An optional Burmester 4D sound system is available. The rear seat is a three-seat bench as standard. More than 60 MANUFAKTUR paints are offered, and forged wheels can now carry colour accents.
The MBUX system runs on the Mercedes-Benz Operating System (MB.OS) and includes three AI agents: ChatGPT, Microsoft Bing and Google Gemini. Three AMG apps sit alongside it. AMG PERFORMANCE MENU shows real-time energy flow, aero status and tyre temperatures.
AMG SET-UP lets drivers configure steering-wheel functions and aero settings. AMG TRACK PACE records more than 80 vehicle data points ten times per second, shows lap and sector times, and can overlay a saved racing line in augmented reality.
Built in Sindelfingen
The SUV is assembled in Hall 32 at Sindelfingen, a hall retrofitted for AMG.EA technology. The plant also produces the pressed parts, body-in-white and paintwork. Sindelfingen was founded in 1915.
