Affalterbach. The Mercedes‑AMG GT 4‑Door Coupé redefines performance: With extreme power, enormous continuous performance, highly precise driving dynamics, and a thrilling AMG intensive driving experience, the four-door sports car catapults performance and driving pleasure to a new level. The 4‑Door Coupé is based on the high-performance AMG.EA architecture and consequently underlines Affalterbach’s pioneering spirit with numerous world firsts. Central to this is a newly developed drive concept, strictly designed for high performance, which is being used for the first time in a series-production EV. It utilises a new, highly innovative electric motor technology, so-called axial flux motors, combined with a high-performance battery. The result is a drive unit that not only impressively delivers peak power but can also call upon it repeatedly and continuously, thereby shifting the benchmark in the high-performance segment. Mercedes‑AMG demonstrated the capability of this technology last year with the spectacular record drive of the CONCEPT AMG GT XX in Nardò. The technology demonstrator sprinted over 40,000 kilometres in seven days and 13 hours – literally driving “around the world in eight days” – and pulverised a total of 25 long-distance records in the process.
Customers will be able to choose between two powerful powertrains at the start of ordering in the coming days: the Mercedes‑AMG GT 63 4-Door Coupé and the Mercedes‑AMG GT 55 4-Door Coupé. The pricing for the models will be based on comparable predecessor vehicles.

Key Facts:
The new Mercedes‑AMG GT 4‑Door Coupé is a masterpiece of engineering. A multitude of innovations and world firsts offer customers more high performance, emotion, and driving pleasure than ever before:
Driven by a revolutionary concept: For the first time in an all-electric series production vehicle, so-called axial-flux motors are used in the new Mercedes‑AMG GT 4‑Door Coupé. The sports car utilises three of these highly innovative electric motors, two on the rear axle, one at the front. Together, they unleash a system output of up to 860 kW (1,169 hp). This is complemented by a high-performance battery concept that not only guarantees enormous but also repeatedly available power – coupled with impressively fast energy absorption and high power density.
Impressive performance: The sprint from 0 to 100 km/h is achieved in just 2.1 seconds, while the vehicle requires only 6.4 seconds for acceleration from 0 to 200 km/h.2 The top speed is 300 km/h (with optional Driver’s Package).
Impressive charging speed: The new Mercedes‑AMG GT 4‑Door Coupé is not only fast on the road but also at the charging station. Thanks to a charging capacity of 600 kW, over 460 kilometres of range can be recharged in just 10 minutes.1 For the typical charging cycle from 10 to 80 % State of Charge (SoC), only 11 minutes are required.
V8 driving excitement programmed: Those who love V8 engines will adore this car. In AMGFORCE S+ mode, the Mercedes‑AMG GT 4‑Door Coupé delivers a highly authentic, AMG signature V8 sound spectacle, coupled with a haptic-immersive experience including traction interruption during simulated gear changes. An adapted driver display in the central tube design perfects the perception of a high-performance V8 sports car. Hard to describe, but all the more impressive to experience. It feels and sounds like you’re in a high-power V8 car, with this mode activated.
Professional-level driving dynamics: With the AMG RACE ENGINEER, ambitious drivers can tailor the dynamics of the Mercedes‑AMG GT 4‑Door Coupé even more individually to their driving style. Thanks to intelligently linked hardware and software, response, traction and cornering behaviour can be precisely controlled. This way, the AMG RACE ENGINEER sharpens agility and catapults the driving experience to an impressive new level.
Active Aerodynamics: To optimally transfer the untamed power to the road, the aerodynamics of the four-door sports car adapt lightning-fast to every driving situation – for maximum dynamics and efficiency. The 4‑Door Coupé features several innovative new developments: Two active AEROKINETICS venturi flow plates in the underbody and the active AEROKINETICS rear diffuser.
Outstanding performance and continuous power thanks to a revolutionary drive concept
Mercedes‑AMG continues its impressive tradition of high-performance drivetrains and is ushering in a new level of performance in the Mercedes‑AMG GT 4‑Door Coupé. At its core are revolutionary axial flux motors that work hand in hand with a completely new battery technology. Both models are equipped with three axial flux motors and deliver an output ranging from 600 kW to 860 kW (816 hp to 1,169 hp). The newly developed battery concept uses directly cooled cylindrical cells with a special cell chemistry that ensures uniform temperature distribution and high-performance stability under continuous load.
Impressive power: Up to 860 kW peak output
The basic principle of the axial flux motor was developed by the British electric-motor specialist YASA, which has been a wholly owned subsidiary of Mercedes‑Benz AG since July 2021. The compact motor design allows greater flexibility in packaging the drivetrain. Compared with conventional electric motors, this innovative drive delivers higher continuous power and higher torque. This also allows demanding driving performances to be reproduced very frequently in succession.
How it works: In an axial flux motor, the electromagnetic flux runs parallel to the motor’s axis of rotation. In a conventional electric motor, it runs perpendicular to the axis. Key components of the axial flux motor are designed as thin discs: two rotors enclose the stator like a sandwich on the left and right. This arrangement – also known as an H-configuration – allows optimal coupling of the magnetic flux generated by the stator to the rotors. In the new Mercedes‑AMG GT 4‑Door Coupé, this combination at the front axle is just about nine centimetres wide; the two motors at the rear axle each measure only around eight centimetres in width. All three of these innovative electric motors together deliver exceptional overall performance in the new Mercedes‑AMG GT 4‑Door Coupé: In the GT 63 4-Door Coupé 4MATIC+, peak output (Peak Performance during AMG Launch Control at 80 % SoC) reaches 860 kW (1,169 hp). The Mercedes‑AMG GT 55 4-Door Coupé 4MATIC+ delivers 600 kW (816 hp). The High Performance Electric Architecture is technologically designed for even higher outputs of over 1,000 kW.
The motors are integrated into a High-Performance Electric Drive Unit (HP.EDU) on each axle. At the rear axle, the HP.EDU contains two axial flux motors, which are combined together with a compact single-stage planetary gearbox in a shared housing. The motors and gearboxes are oil cooled. The required Pump Control Unit, including hydraulic pumps and suction filters, is also integrated into the HP.EDU to save space. In addition, two water-cooled silicon-carbide (SiC) inverters (one per motor) are used. The material properties of silicon carbide offer numerous benefits for demanding applications that requirehigh voltages, high currents, high temperatures, and excellent thermal conductivity. The axial flux motors reach more than 13,000 rpm at top speed.
The front HP.EDU contains one axial flux motor, a spur-gear transmission with integrated parking lock, a liquid-cooled silicon-carbide (SiC) inverter, and a Pump Control Unit. The axial flux motor reaches more than 15,000 rpm at top speed. The front electric drive acts as a “booster motor”, activated only when additional power or traction is required on the front axle. For increased efficiency under low load, the so-called Disconnect Unit (DCU) decouples the front-axle electric motor within milliseconds, reducing unnecessary drag losses. During acceleration and recuperation, the DCU closes for optimal performance. During steady state driving, low load, or coasting, it reopens to reduce drag losses and increase efficiency.
Inspired by Formula 1, developed in Affalterbach: The AMG high performance electric battery
The high-voltage battery of the new Mercedes‑AMG GT 4‑Door Coupé is a completely new development and the result of concentrated expertise. It combines experience from the Mercedes‑AMG ONE hypercar, the uncompromising performance philosophy of Formula 1®, and the deep know-how of Mercedes‑AMG’s top engineers in Affalterbach, together with Mercedes‑AMG High Performance Powertrains (HPP) in Brixworth, England. This “AMG High Performance Electric Battery” (AMG HP.EB) is the key to the vehicle’s outstanding overall performance. It enables not only high output, but also performance that can be called upon repeatedly, combined with impressively fast energy absorption and a high-power density. The battery concept is designed to potentially enable WLTP ranges of well over 700 kilometres in the future.
Three key aspects contribute significantly to this outstanding performance capability: newly developed battery cells, an innovative direct cooling system for each individual cell, and a comparatively high voltage.
Newly developed battery cell for the highest performance requirements
The high-voltage battery in the new Mercedes‑AMG GT 4‑Door Coupé is the result of a groundbreaking new development designed specifically for maximum performance. At the heart of this innovation is a battery cell with a distinctive shape:cylindrical, tall and slim. The cells are 105 millimetres high and measure 26 millimetres in diameter. This unique format provides crucial advantages for cooling. The small diameter of the round cell minimises the distance from the cell core to the surface. This enables rapid and efficient dissipation of heat generated under load, ensuring that each individual round cell is always maintained within its optimal temperature range. This is essential for consistent power delivery and battery longevity, even under extreme conditions.
The innovations in the high-voltage battery of the new Mercedes‑AMG GT 4‑Door Coupé go even further: the laser-welded aluminium cell housing is also a new development. It is not only significantly lighter than conventional “steel cans” but also offers outstanding electrical and thermal conductivity. These properties enable more precise and effective cell temperature control, allowing the cell to cool down or warm up more quickly as needed. Another highlight is the full-tab design of the cells. Here, the cell windings are connected electrically and thermally across the entire surface of the poles. The result is asignificant reduction in internal resistance, enabling extremely high charging and discharging performance. In addition, these full-tab battery cells are extremely robust and remain reliable even under extreme loads.
In the new Mercedes‑AMG GT 4‑Door Coupé, a specially developed cell chemistry is used. It is based on NCMA (Nickel/Cobalt/Manganese/Aluminium) in the cathode and a silicon-containing anode. It also offers a previously unique combination of high energy density – over 298 Wh/kg or 732 Wh/l at cell level – together with strong charging performanceand long service life.
