The new 1,169-hp Mercedes-AMG GT 4-Door Coupe is a masterpiece of engineering featuring a multitude of innovations and world firsts to offer customers higher performance and driving pleasure than ever before. But hold on to your hat. Boasting three axial-flux motors, it will do 0 to 60 in about 2 sec. To be exact, the sprint from 0 to 62 mph is achieved in just 2.1 sec, while the vehicle requires only 6.4 sec for acceleration from 0 to 124 mph. The top speed is 186 mph.

The sports car utilizes three highly innovative electric motors -- two on the rear axle, one at the front -- that work hand in hand with a completely new battery technology. The new coupe is not only fast on the road but also at the charging station. Thanks to a charging capacity of 600 kW, over 285 miles of range can be recharged in just 10 minutes. The typical charging cycle from 10 to 80% takes only 11 minutes.

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 Coupe (max power = 1,169 hp) and the Mercedes-AMG GT 55 4-Door Coupe (max power = 816 hp).

Not so keen on EVs? Mercedes says, "Those who love V-8 engines will adore this car. In AMGFORCE S+ mode, the Mercedes-AMG GT 4-Door Coupe delivers a highly authentic, AMG signature V-8 sound, 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 V-8 sports car. Hard to describe, but all the more impressive to experience. It feels and sounds like you're in a high-power V-8 car with this mode activated."

Manual gear changes via the steering-wheel paddles are executed with precise shift characteristics for maximum performance. An intelligent real-time mixing system uses more than 1,600 sound files to sonically interpret each driving situation. The experience is dynamically context-dependent and adapted in real time to the current driving style. For acceleration processes, gear changes, or burbling -- the entire sonic spectrum of a modern performance vehicle is made accessible.

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.

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 Coupe, this combination at the front axle is just about 9 cm wide; the two motors at the rear axle each measure only around 8 cm in width.

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 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.

The high-voltage battery of the new coupe is a completely new development. It combines experience from the Mercedes-AMG ONE hypercar, Formula 1, and the deep know-how of Mercedes-AMG's top engineers in Affalterbach, Germany, and Brixworth, England. It enables not only high output, but also performance that can be called upon repeatedly. The battery concept is designed to potentially enable WLTP ranges of well over 435 miles 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.

The high-voltage battery in the floor of the car 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. Overall, 2,660 cells are used. The cells are 105 mm high and measure 26 mm in diameter. This unique format provides crucial advantages for cooling. The small diameter of the round cell minimizes the distance from the cell core to the surface. The laser-welded aluminum 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. Full-tab technology and NCMA chemistry completes the foundation for maximum performance. The high voltage of the 800-V lithium-ion energy storage system also contributes to overall performance.

Design-wise, the body-in-white of the new coupe is a completely new development. The intelligent material mix of aluminum, steel, and fiber-reinforced composites combines the typically high AMG rigidity with low weight. Optimized material cross-sections and component geometries create space for the demanding technology and the complex chassis. The high-voltage battery is integrated centrally into the structure of the e-skateboard.

Shaped by its dynamic fastback, the long, low-slung front hood, the steeply raked windshield, and the distinctive rear diffuser, the vehicle makes a bold statement of maximum sportiness. The car is 4 cm lower than its predecessor.

Up front, you can't miss the AMG-specific grille with its vertical slats and optionally illuminated, concave shape along with the illuminated, centrally positioned Mercedes star and star running lights. Another design highlight is the motorsport-derived hood with two pronounced power domes. In the side view, the athletic design language continues, with the strongly flared fenders emerging from the low front. True to sports-car tradition, the exterior mirrors are mounted directly on the doors, while flush-fitting door handles underscore the aerodynamic refinement. The large wheels and long wheelbase further emphasize the sporty proportions.

From a bird's-eye perspective, the tapering of the greenhouse toward the rear becomes visible, giving the car its extremely wide, athletic shoulder line. Six circular taillights in turbine design with star graphics lend the sports car an unmistakable rear identity. An optional, impressive light strip used as an additional taillight further enhances the sporty appearance. Visually, the body sits on a powerful, black-gloss contrast base that extends from the front splitter wrapping around the vehicle's front, along the side sills, and to the rear. Extremely short overhangs complete the racy proportions.

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 coupe features several innovative new developments: Two active AEROKINETICS venturi flow plates in the underbody and the active AEROKINETICS rear diffuser. The seamlessly integrated, extendable rear spoiler adjusts its position depending on the driving situation.

Other standout features for the car include: AMG active ride control suspension with semi-active roll stabilization, multi-link front and rear axles, AMG Race Engineer Control Unit, active rear-axle steering, fully variable AMG Performance 4MATIC+ all-wheel drive, and a high-performance composite brake system with strong recuperation and weight-optimized brake discs. The wheel portfolio available to customers ranges from 19- to 21-in. light-alloy and forged wheels, including aerodynamically optimized designs.

In the interior, pure sports-car genes meet grand-tourer attributes. The characteristically low, perfectly integrated seating position immediately conveys a focused, emotional driving feel -- much like a two-door racer.

The instrument panel is defined by a wide, visually continuous display unit that separates into a driver-oriented area and a slightly offset passenger area. The razor-sharp driver displays -- consisting of the 10.2-in. instrument cluster and the 14-in. multimedia monitor -- merge into a single unit in a "seamless-glass" design. The 14-in. multimedia monitor is ergonomically angled toward the driver, ensuring optimal readability and intuitive operation. A 14-in. passenger display with its own content is also available.

The uniquely designed center console brings together aesthetics and functionality. A highlight is the three haptic driving-dynamics rotary controllers.

The newly developed front seats, featuring a sporty and expressive design, offer excellent lateral support during dynamic cornering. Even sportier are the optional AMG Performance seats with integrated head restraints. Extensive customization options are available through the exclusive MANUFAKTUR program.

The rear is equipped as standard with comfortable, contoured individual seats for two people and surprisingly generous headroom. A one-piece panorama glass roof contributes to the airy sense of space.

AMG TRACK PACE is also included in the new Mercedes-AMG GT 4-Door Coupe and turns every racetrack visit into a professional training session. The highly advanced software is integrated into the MBUX infotainment system and records more than 80 vehicle-specific data points 10 times per second while driving on a racetrack.

The pricing for the models will be based on comparable predecessor vehicles. Availability starts later this summer. The Mercedes-AMG GT 55 4-Door Coupe should start around $140,000, and the Mercedes-AMG GT 63 4-Door Coupe should start around $210,000.
