The Mercedes-AMG GT Black Series is not just a car; it’s a statement. It’s the culmination of decades of motorsport heritage distilled into its purest, most potent form for the road. Affalterbach’s engineers have unleashed their full arsenal of expertise to create a vehicle that redefines the boundaries of performance and driving dynamics. This is the most extreme and track-focused iteration of the AMG GT lineage, a roaring testament to the brand’s unwavering commitment to pushing limits. The new Mercedes-AMG GT Black Series emerges as the ultimate expression of power and precision, cloaked in the iconic black, signifying its unparalleled status within the Mercedes-Benz and AMG family.
Since 2006, the Black Series designation at Mercedes-AMG has represented something truly exceptional: uncompromising performance, aggressive aesthetics, and a direct line of technology transfer from the intense world of motorsport to series production vehicles. These are not cars meant for gentle Sunday drives; they are built for blistering lap times and exhilarating track experiences, all while retaining road legality. The AMG GT Black Series elevates this philosophy to a new zenith. It boasts the most powerful AMG V8 engine ever placed in a production car, making it a true automotive rarity designed for those who demand the absolute peak of performance.
The heart of this beast is a meticulously handcrafted AMG 4.0-liter V8 engine, but to simply call it an evolution would be a disservice. Engineers in Affalterbach undertook a radical redevelopment of this already formidable power unit to surpass even the most demanding expectations. The objective was clear: to generate significantly more power than any preceding AMG GT model, achieve an even sharper throttle response, and deliver colossal torque. This ambition necessitated a fundamental shift in engine design, leading to the adoption of a flat-plane crankshaft – a technology with profound implications for the engine’s character and output.
Tobias Moers, former Chairman of the Board at Mercedes-AMG GmbH, aptly described the significance of this machine: “The new GT Black Series is our latest automotive highlight and continues a tradition established in 2006. The sixth iteration of its kind is another AMG milestone and impressive proof of the incredible development expertise in Affalterbach. I am proud of the team who have created this unique super sports car, which now represents the absolute peak of our successful GT family. The performance, appearance and driving dynamics of the GT Black Series are second to none.” His words underscore the gravity of the GT Black Series as not just a new model, but a landmark achievement for AMG.
The Distinctive Heart: AMG’s Flat-Plane Crankshaft V8
The configuration of a V8 engine offers significant design flexibility, particularly in the crankshaft arrangement. This crucial component dictates the engine’s fundamental characteristics. Traditionally, V8 engines employ one of two crankshaft designs: the cross-plane crankshaft, where crankpins are positioned at 90-degree intervals, or the flat-plane crankshaft, where all crankpins lie on a single plane with a 180-degree offset. AMG’s prior V8 engines have all utilized the cross-plane configuration. However, for the GT Black Series, a bold departure was made in favor of the flat-plane design to unlock unprecedented performance potential.
Visually, a cross-plane crankshaft, when viewed from the front, exhibits the ‘cross’ that gives it its name. This design offers inherent advantages in smoothness and generates substantial torque at lower engine speeds. The deep, rumbling exhaust note characteristic of cross-plane V8s is also a defining trait. In the AMG 4.0-liter biturbo V8, engineers ingeniously positioned the exhaust side within the engine’s ‘hot inside V’ configuration, optimizing space and thermal management.

Unleashing Power Through Uniform Oscillation
The transition to a flat-plane crankshaft is a strategic move to further amplify engine performance. In a flat-plane V8, the crankshaft resembles that of an inline four-cylinder engine, albeit with wider crankpins to accommodate two connecting rods each. The firing sequence in a flat-plane V8 alternates between cylinder banks, enhancing the gas cycle. The specific firing order, with a 180-degree crankshaft angle offset (1-8-2-7 4-5-3-6), creates evenly spaced, oscillating gas columns in both the exhaust and intake tracts. This uniformity allows for resonance tuning to boost performance. Furthermore, a flat-plane crankshaft drastically improves throttle response, lending the engine an eager and immediate character.
The Most Potent V8 to Wear the Three-Pointed Star
While the AMG GT Black Series engine retains the foundation of the AMG 4.0-liter V8 biturbo with dry sump lubrication, its extensive modifications warrant a new internal designation: M178 LS2. This powerhouse churns out an astounding 720 hp between 6,700 and 6,900 rpm, and a massive 590 lb-ft of peak torque spanning from 2,000 to 6,000 rpm. The engine’s transformation includes new camshafts and exhaust manifolds, meticulously calibrated to the unique firing order, further optimizing the gas exchange process.
Echoing the top-tier AMG GT 4-Door Coupe, the twin-scroll exhaust turbochargers in the Black Series engine are mounted on anti-friction bearings, sharpening throttle response. However, for the GT Black Series, these turbochargers are fitted with larger compressor wheels, enabling them to deliver a remarkable 24.6 psi of boost pressure, compared to 19.6 psi in the AMG GT R. The engine’s robust design permits sustained high-speed operation, with the redline set at 7,200 rpm. Enlarged intercoolers ensure optimal charge-air temperatures are maintained under extreme conditions. A unique black engine badge visually distinguishes this exceptional powerplant.
Blistering Performance Metrics
The bespoke AMG engine within the GT Black Series endows it with a truly unique persona, evident not just in its raw power delivery but also in its distinctive, aggressive soundtrack. This potent heart translates into breathtaking performance figures: the Black Series catapults from 0 to 60 mph in a mere 3.1 seconds, and reaches 124 mph (200 km/h) in under nine seconds. Its top speed is electronically limited to 202 mph, a velocity best reserved for the controlled environment of a racetrack.
Enhanced Transmission for Track Domination
Channeling the immense power to the rear wheels is the AMG SPEEDSHIFT DCT 7-speed dual-clutch transmission. Positioned on the rear axle in a transaxle configuration for optimal weight distribution, a hallmark of AMG GT 2-door models, this transmission has been meticulously recalibrated for the GT Black Series. It is engineered to handle the increased torque output and has had its shift speed and response thresholds refined for peak racetrack performance.

These enhancements result in a more responsive and engaging driving experience. Accelerator and engine responses are sharper, and drive programs, start-up characteristics, and gear shifts are all optimized for aggressive driving. The Race Start function is now even more potent, benefiting from elevated starting revs, more precise wheel slip management, and track-focused high-performance tires. The transmission cooling system has been reinforced to endure extreme demands, and the gear ratios have been subtly adjusted to maximize acceleration and responsiveness.
The ‘torque tube,’ crafted from carbon fiber, connects the engine and transmission. Weighing just 30.6 lbs, it achieves a remarkable 40 percent weight reduction compared to its aluminum counterpart in the standard AMG GT. As a structural element within the transaxle drivetrain, it forges an exceptionally torsionally rigid link between the engine and transmission. This contributes to direct drivetrain connection, enhancing driving dynamics and contributing to balanced weight distribution. The driveshaft within the torque tube is also constructed from lightweight carbon fiber.
Aerodynamic Mastery: Sculpted for Speed and Stability
Sophisticated and meticulously optimized aerodynamics are integral to the AMG GT Black Series’ agile handling and high-speed stability on demanding circuits. Aerodynamicists and designers collaborated closely, as they did for the AMG GT R and AMG GT R PRO, to elevate the aerodynamic performance of the Black Series. The design philosophy is unequivocally ‘form follows function.’
The resemblance to the AMG GT3 and AMG GT4 racing cars is stronger than ever, both visually and technically. This begins with the new, significantly enlarged radiator air inlet, directly derived from the AMG GT3 race car. The radiator grille features vertical slats in dark chrome, and with the wheel arch coolers now fed directly via the central inlet, the two outer air inlets in the front bumper are eliminated. Semicircular flics optimize airflow, increasing downforce at the front axle and improving brake cooling. ‘Air curtains’ manage airflow towards the wheels. These refinements, along with flics ahead of the wheels, reduce drag and increase downforce. The new design language prioritizes maximum cooling efficiency, reduced air resistance, and enhanced front-end downforce.
The carbon-fiber front splitter offers two manually adjustable settings: Street and Race (Race setting intended solely for track use). In the Race position, extending the splitter forward creates a front diffuser with an inverted wing profile under the front section. As speed increases, negative pressure further lowers this element, accelerating underbody airflow and creating a ‘Venturi effect.’ This draws the car closer to the road and significantly increases front axle downforce. Drivers will feel the enhanced steering precision, particularly during high-speed cornering, and exceptional directional stability. The car responds with agility and provides clear steering feedback, remaining easily controllable even under high lateral acceleration. When the front diffuser is in Race position, the new rear spoiler design further amplifies rear axle downforce.
Motorsport-Derived Hood and Ventilation
Another direct motorsport influence is the new carbon-fiber hood, featuring two prominent exhaust air outlets finished in black carbon fiber. These large outlets channel hot air from the diagonally positioned cooling pack out of the engine compartment. This technology, directly adopted from racing, boosts overall downforce while simultaneously reducing air resistance and optimizing engine cooling airflow. Air is also strategically guided around the A-pillars and side windows towards the rear, enhancing the effectiveness of the new rear spoiler. Seamlessly integrated front fender vents, with five body-colored fins and exhaust air openings behind the front wheels, contribute to front axle downforce through efficient wheel arch ventilation. The airflow around the vehicle is further optimized by larger, wider side sill panels with black carbon-fiber elements, merging into vertical blades at the front and rear. Integrated cooling air ducts in the side sills provide brake cooling for the rear axle.
Two-Stage Rear Spoiler System
The rear of the GT Black Series is defined by a new bumper with a large diffuser, dual rounded twin-tailpipe trims, side wheel arch ventilation, and an innovative two-stage rear spoiler design. Both spoiler blades are crafted from carbon fiber and are mechanically adjustable to adapt to varying track conditions. The lower blade is intentionally compact, ideal for capturing airflow from the car’s front. Matte black carbon-fiber spoiler supports, meticulously designed through extensive simulations, enhance aerodynamic efficiency. They are bolted to the black carbon-fiber rear hatch.
A key feature is the adjustable flap in the upper blade. This active aerodynamic element electronically adjusts by 20 degrees based on driving conditions and the selected AMG DYNAMICS mode, optimizing both longitudinal and lateral dynamics. In a flat position, it reduces drag for higher top speeds. When inclined, it enhances braking and cornering stability through increased rear axle downforce.
Four activation strategies are available, linked to the AMG DYNAMICS modes (Basic, Advanced, Pro, Master). For example, in Master mode, the flap remains inclined and extended up to 155 mph, then retracts to reduce drag for higher top speeds. However, during sudden braking or cornering, it immediately returns to the extended position to maximize braking and cornering performance. The driver can also manually control the flap via a button on the center console.
Underbody Aerodynamics and Downforce
The comprehensive aerodynamic package extends to a nearly fully paneled underbody, addressing both aerodynamic and thermal (heat dissipation) demands. The flat underbody incorporates longitudinal fins, meticulously optimized to channel airflow to the rear diffuser. This entire system accelerates airflow, significantly increasing downforce. All aerodynamic elements are carefully coordinated, culminating in a downforce level exceeding 882 lbs at 155 mph.
Carbon Fiber Construction: Lightweight Strength
The intelligent material mix and lightweight construction are evident throughout the AMG GT Black Series. The lightweight carbon-fiber roof with a lowered center, the carbon-fiber rear hatch with a small spoiler lip, and the lightweight glass rear windshield are key components. The laminated front windshield also utilizes lightweight glass. A coiled carbon-fiber transmission mount is another exclusive Black Series feature. Carbon-fiber shear panels in the front, underbody, and rear sections, along with a lightweight integral carrier and carbon-fiber cross tunnel, reinforce the aluminum body shell, enhancing structural rigidity. These elements create a connected network, contributing to the Black Series’ exceptional driving precision in all maneuvers. The carbon-fiber shear panel under the engine, connected to the integral carrier, stiffens the front section and steering system, improving steering precision and front axle stability. The integral carrier at the front axle is exclusively crafted for the Black Series using lightweight aluminum.
The standard ceramic high-performance compound brake system, with black calipers and white lettering, also minimizes weight while delivering exceptional braking power. Special brake pads and rotors, combined with enhanced brake cooling, ensure consistent, fade-free deceleration and precise brake modulation. Standard lightweight alloy forged wheels further contribute to weight reduction.
AMG Coil-Over Suspension: Tuned for the Track
A double wishbone suspension design provides exceptional wheel control with high camber and toe-in stability, enabling high cornering speeds and optimized road feel at the limits of adhesion. Wishbones, steering knuckles, and hub carriers on both axles are forged from aluminum to minimize unsprung mass. Spherical bearings on the rear axle wishbones, derived directly from motorsport, eliminate play, ensuring consistent toe-in and camber even under extreme loads. This contributes to the GT Black Series’ precise steering, clear feedback, and superior cornering performance.

Like the AMG GT R, the Black Series utilizes an AMG coil-over suspension with adjustable spring preload, tailored for extreme racetrack demands. This motorsport technology is integrated with the AMG RIDE CONTROL continuously variable adaptive damping system. Electronically controlled, it automatically adjusts damping at each wheel based on driving situation, speed, and road conditions. New valves, also motorsport-derived, for rebound and compression forces enable rapid and precise damping modulation, reacting even more quickly to suspension movements. Firmer damping during cornering and braking effectively reduces body roll. Continuous damping adjustment ensures optimal road contact and enhanced safety even at high speeds.
Drivers can adjust damping characteristics via a button on the AMG DRIVE UNIT or through AMG DYNAMIC SELECT drive modes, offering Comfort, Sport, and Sport Plus settings. Modified logic provides an improved balance between ride and handling. Sport Plus mode intelligently adapts to track surface quality, automatically adjusting damping levels based on whether the car is on a smooth Grand Prix circuit or a bumpy track like the Nürburgring Nordschleife.
Suspension Weight Reduction and Adjustability
The front axle features a dual adjustable sway bar made of lightweight carbon fiber, with a firm default setting. The rear axle sway bar, made of steel with a hollow tube design for weight savings, offers 3-way adjustability. The carbon-fiber shear panel in the rear underbody further enhances driving precision by stiffening the rear structure. Electronically controlled dynamic engine and transmission mounts have been retuned for increased agility and precise response.
Additional suspension measures include wider front and rear tracks and manually adjustable camber at both axles, allowing for extreme camber settings optimized for track performance.
Custom Michelin® Pilot Sport Cup 2 R MO tires, developed specifically for the Black Series, are available in two compounds. The standard tire is the soft-compound Michelin® Pilot Sport Cup 2 R MO1A. A harder compound option (Michelin® Pilot Sport Cup 2 R MO2) is available for track use in higher temperatures through the AMG Performance Center. Tire sizes are 285/35 ZR 19 front and 335/30 ZR 20 rear, mounted on 10 J x 19 and 12 J x 20 wheels, respectively.
AMG TRACTION CONTROL: Nine Levels of Grip
For closed-track use with ESP OFF, AMG TRACTION CONTROL provides adjustable support for managing the Black Series’ immense power without ESP brake intervention. Offering nine levels of slip control on the rear axle, it allows drivers to fine-tune assistance for their skill level and track conditions. Control is managed through engine electronics maps, without ESP system intervention, similar to the GT3 racing car.
A dedicated adjuster on the center console, operable even with racing gloves, controls the system. Level 1 provides maximum safety reserves for wet conditions, while level 9 allows for maximum rear axle slip. The selected level is displayed on the adjuster and in the instrument cluster. AMG TRACTION CONTROL anticipates situations using a friction coefficient evaluator and other data, calculating permissible rear wheel slip based on the selected level. When this slip level is reached, the system modulates engine output and the electronic differential lock to maintain the specified slip and continue acceleration.
Exclusive Interior and AMG-Specific Displays
The interior design reinforces the AMG GT Black Series’ performance focus. Exclusive nappa leather is paired with sporty black DINAMICA microfiber featuring orange contrasting topstitching. Black DINAMICA microfiber trims the instrument panel and lightweight door panels with loop pull handles. Further orange stitching, matte black carbon-fiber trim, and the Interior Night Package accentuate the interior. AMG carbon-fiber bucket seats (not available in the USA, Canada, and China) offer low weight and maximum lateral support. AMG Performance seats are standard in the USA, Canada, and China. Silver contrasting topstitching is optional.
The AMG GT Black Series features digital instrument displays from the AMG GT family, with a 12.3-inch instrument cluster and a 10.25-inch multimedia display. The instrument cluster offers AMG-specific display styles: ‘Classic’, ‘Sporty’, and ‘Supersport’. ‘Supersport’ view includes a central rev counter and additional performance information. The multimedia display provides animated visualizations of vehicle functions.
Colored display buttons in the V-shaped center console control transmission logic, suspension, ESP, exhaust system, rear spoiler flap, and start/stop function. These TFT display buttons are intuitive and glove-operable, supplemented by rocker switches for drive programs and audio volume.
The AMG Performance steering wheel, adopted from the AMG GT family, features a sporty design, flattened bottom, DINAMICA microfiber trim, and a Black Series badge. Aluminum shift paddles enable manual gear changes. Integrated Touch Control buttons manage instrument cluster and multimedia display functions. Standard AMG DRIVE UNIT steering wheel buttons include a round controller for drive programs and two configurable display buttons for AMG functions.
