Mercedes-AMG GT Black Series: Unleashing the Most Powerful AMG V8 Engine Ever

The Mercedes-AMG GT Black Series is not just another car; it’s a statement. Born from the fiery crucible of motorsport and engineered with relentless precision, this super sports car redefines the boundaries of performance and driving dynamics. Affalterbach’s engineers have truly outdone themselves, crafting a machine that embodies AMG’s racing pedigree while delivering an unparalleled driving experience on both track and road. At its heart lies the most potent AMG V8 series engine ever created, harmoniously paired with sophisticated aerodynamics, an intelligent blend of materials, and an aggressively expressive design that screams performance. This is the Mercedes-AMG GT Black Series – the absolute pinnacle of the AMG GT family.

Since 2006, the Black Series designation at Mercedes-AMG has signified something extraordinary: uncompromising sportiness, a design that commands attention, and technology directly descended from the racetrack. Black Series models are not mere showpieces; they are exclusive, rare breeds built for exhilarating high-speed track experiences while still being fully road-legal. The AMG GT Black Series elevates this tradition to new heights, proudly housing the most powerful Mercedes-AMG V8 series engine ever conceived.

To surpass the already exceptional super sports car benchmark, AMG’s engine specialists in Affalterbach undertook a comprehensive redevelopment of the renowned 4.0-liter V8 biturbo engine. Despite its established reputation for responsiveness, power delivery, and robust torque, the team aimed for significantly more power than any previous AMG GT flagship. This ambition demanded a radical transformation, culminating in the adoption of a flat-plane crankshaft – a first for an AMG V8 in a series production car.

Tobias Moers, former Chairman of the Board at Mercedes-AMG GmbH, aptly described the significance of this model: “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.”

The Distinctive Heart of the Beast: A Flat-Plane Crankshaft V8

The architecture of a V8 engine provides considerable scope for engineers to influence engine characteristics through crankshaft design. Typically, V8 engines employ one of two crankshaft configurations: the cross-plane crankshaft or the flat-plane crankshaft. AMG’s previous V8 engines utilized the cross-plane design, where the crankpins of each cylinder pair are positioned at 90-degree angles. In contrast, the flat-plane crankshaft arranges all crankpins on a single plane with a 180-degree offset.

Looking head-on at a cross-plane crankshaft reveals the ‘cross’ shape that lends it its name. These crankshafts are celebrated for their smooth operation and substantial low-end torque. The signature burbling exhaust note is another defining trait of cross-plane V8 engines. To optimize the displacement and performance potential of the 4.0-liter V8 biturbo, AMG engineers strategically positioned the exhaust side within the ‘hot inside V’ of the cylinder banks.

Unlocking Performance: The Advantages of Uniformly Oscillating Gas Columns

The flat-plane crankshaft is instrumental in further boosting engine performance. In a flat-plane V8, the engine configuration resembles an inline four-cylinder, save for the wider crankpins accommodating two connecting rods each. Ignition in this configuration alternates between cylinder banks, enhancing the gas cycle. The distinct firing order, characterized by a 180-degree crankshaft angle offset (1-8-2-7 4-5-3-6), generates uniformly oscillating gas columns within both the exhaust and intake tracts. These consistent gas pulses create resonance that can be effectively harnessed to amplify engine power. Moreover, a flat-plane crankshaft delivers a more immediate and agile throttle response, crucial for a high-performance machine like the Mercedes-AMG GT Black Series.

The Most Powerful AMG V8 Engine to Date

While the new engine in the GT Black Series shares its foundation with the AMG 4.0-liter V8 biturbo featuring dry sump lubrication, it has been designated the new internal code M178 LS2 due to extensive modifications. This powerhouse churns out an astounding 720 hp at 6,700-6,900 rpm and a colossal 590 lb-ft of peak torque across the 2,000-6,000 rpm range. New camshafts and exhaust manifolds are specifically tailored to the unique firing order of the flat-plane crank, further optimizing the gas cycle.

Mirroring the top-tier AMG GT 4-Door Coupe, the twin-scroll exhaust turbochargers are equipped with anti-friction bearings for enhanced throttle response. However, the GT Black Series turbochargers boast larger compressor wheels, enabling them to deliver a total boost pressure of 24.6 psi, a notable increase compared to the 19.6 psi of the AMG GT R. The engine’s redline extends to 7,200 rpm, with 7,000 rpm well within the engine’s continuous operating range. Larger intercoolers ensure optimal charge-air temperatures are maintained. The exclusivity of this engine is visually underscored by a distinctive black engine badge.

Blistering Performance Figures: 0-60 mph in 3.1 Seconds

The bespoke AMG engine endows the GT Black Series with a unique character, evident not only in its power delivery but also in its distinctive, ferocious sound. The performance metrics are nothing short of breathtaking: 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 figure best explored on closed racetracks.

Optimized Transmission for Track Domination

Power is channeled to the rear wheels via the AMG SPEEDSHIFT DCT 7-speed dual-clutch transmission. Positioned on the rear axle in a transaxle configuration for optimal weight distribution, as with all AMG GT 2-door models, this transmission has been meticulously recalibrated for the AMG GT Black Series to handle the immense 590 lb-ft of torque. Shift speeds and response times have been further sharpened, making it even more track-focused.

The result is enhanced agility in accelerator and engine response, drive programs, start-up behavior, and gear changes. The Race Start function is now even more potent, benefiting from increased starting revs, more sensitive wheel slip control, and high-performance track-ready tires. Transmission cooling has been upgraded to withstand harsher demands, and gear ratios have been subtly revised.

A carbon fiber ‘torque tube’ connects the engine and transmission. Weighing a mere 30.6 lbs, it is approximately 40 percent lighter than the already optimized aluminum component in the standard AMG GT. As a structural element of the transaxle drivetrain, it provides exceptional torsional rigidity between the engine and transmission, promoting direct drivetrain connection and contributing to the vehicle’s balanced weight distribution. The driveshaft within the torque tube is also constructed from lightweight carbon fiber.

Aerodynamic Mastery: Sculpted for Speed and Downforce

Sophisticated and meticulously honed aerodynamics are crucial to the GT Black Series’ agile driving dynamics and high-speed stability on demanding circuits. Aerodynamicists and designers collaborated closely, mirroring the development process for the AMG GT R and AMG GT R PRO, to further refine the aerodynamic profile of the GT Black Series. “Form follows function” is the guiding principle, and the resemblance to the AMG GT3 and AMG GT4 racing cars is stronger than ever.

The larger radiator air inlet, directly derived from the AMG GT3 race car, is immediately noticeable. The radiator trim features vertical slats in dark chrome. With 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 front axle downforce and enhancing brake cooling. ‘Air curtains’ manage airflow towards the wheels, and together with flics ahead of the wheels, reduce drag and increase downforce. This design language balances maximum cooling efficiency with reduced air resistance and enhanced front downforce.

The carbon fiber front splitter offers two manually adjustable settings: Street and Race (the latter exclusively for track use). In the Race position, extending the splitter forward creates a front diffuser shaped like an inverted wing profile beneath the front section. This element lowers further with increasing negative pressure at higher speeds, accelerating underbody airflow and creating a ‘Venturi effect’. This draws the car closer to the road and significantly increases front axle downforce, enhancing steering precision and directional stability, particularly during high-speed cornering. With the front diffuser in Race position, the new rear spoiler design can further augment rear axle downforce.

Performance-Enhancing Hood and Fender Vents

Another motorsport-derived feature is the new carbon fiber hood with two prominent black-finished carbon fiber exhaust air outlets. These large outlets channel hot air from the diagonally positioned cooling pack out of the engine compartment, increasing overall downforce and reducing air resistance while optimizing airflow for engine cooling. Air is also directed 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 further contribute to front axle downforce through efficient wheel arch ventilation. The airflow around the vehicle is also refined by larger, wider side sill panels with black carbon fiber elements, merging into vertical blades at the front and rear. Additional cooling air ducts are integrated into the side sill panels for rear brake cooling.

Two-Stage Rear Spoiler: Adjustable Aerodynamic Force

The rear of the AMG GT Black Series is defined by a new rear bumper with a large diffuser, twin rounded tailpipe trims, side wheel arch ventilation, and an innovative two-stage rear spoiler. Both spoiler blades are crafted from carbon fiber and are mechanically adjustable to adapt to diverse track conditions. The lower blade is intentionally compact and narrow to optimally interact with incoming airflow. Matte black carbon fiber spoiler supports, meticulously designed through extensive simulations, enhance aerodynamic efficiency and are bolted to the black carbon fiber rear hatch.

A key feature is the adjustable flap in the upper blade. This active aerodynamic element is electronically adjusted by 20 degrees based on driving conditions and the selected AMG DYNAMICS mode, improving both longitudinal and lateral dynamics. In a flat position, it minimizes air resistance for quicker acceleration to top speed. In an inclined position, it enhances braking and cornering stability through increased rear axle downforce.

Four activation strategies are available, linked to the selected AMG DYNAMICS mode (Basic, Advanced, Pro, or Master), and some incorporate driving dynamics recognition. For instance, in Master mode, the flap is permanently inclined up to 155 mph, retracting above this speed to reduce drag and maximize top speed. However, during sudden braking or cornering, the flap instantly returns to its extended position for optimized braking and cornering performance. Drivers can also manually control the flap via a dedicated button on the center console.

Comprehensive Underbody Paneling for Enhanced Aerodynamics

The meticulous aerodynamic development extends to the virtually fully paneled underbody, addressing both aerodynamic and thermal management (heat dissipation) requirements. The flat underbody features longitudinal fins, meticulously optimized to channel airflow to the rear diffuser. This comprehensive package accelerates airflow and substantially increases downforce. All aerodynamic elements are carefully coordinated and work in concert with the new rear spoiler design. The culmination of these efforts is a downforce exceeding 882 lbs at 155 mph.

Lightweight Construction: Carbon Fiber Throughout

The intelligent material mix and lightweight construction are evident in the carbon fiber roof with a lowered center, the carbon fiber rear hatch with a small spoiler lip, and the lightweight glass rear windshield. The laminated front windshield also utilizes lightweight glass. A coiled carbon fiber transmission mount is another Black Series exclusive. Carbon fiber shear panels in the front section, underbody, and rear, along with a lightweight integral carrier and carbon fiber cross tunnel, stiffen the aluminum body shell, enhancing driving precision. The carbon fiber shear panel beneath the engine connects to the integral carrier, stiffening the front section and steering system, resulting in more precise steering and front axle stability. The front axle integral carrier is exclusively crafted for the Black Series from lightweight aluminum.

The standard ceramic high-performance compound brake system with black calipers and white lettering is also lightweight and high-performing. Special brake pads and rotors, along with enhanced brake cooling, ensure consistent, fade-free deceleration and precise brake application. Standard light-alloy forged wheels further contribute to weight reduction.

AMG Coil-Over Suspension: Tuned for Track Precision

A double wishbone suspension design provides high camber and toe-in stability, enabling exceptional cornering speeds and optimized road feedback 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’s upper and lower wishbones, derived from motorsport, eliminate play and maintain consistent toe-in and camber even under extreme loads. This translates to precise steering, clear feedback, and superior cornering performance.

As with the AMG GT R, the Black Series utilizes an AMG coil-over suspension with adjustable spring preload, featuring technology adapted for demanding track use with high damping forces. 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 conditions, speed, and road surface. Damping characteristics are modulated rapidly and precisely by separate valves for rebound and compression forces, also derived from motorsport. These valves react even more quickly to rapid 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 the AMG DRIVE UNIT or AMG DYNAMIC SELECT drive modes. Three modes are offered: “Comfort,” “Sport,” and “Sport Plus.” Modified logic optimizes the balance between these modes. “Comfort” and “Sport” are suitable for public roads, with “Sport” providing firmer damping and a sportier feel, also suitable for tracks in wet conditions. “Sport Plus” is ideal for racetracks and intelligently adapts to track surface quality, automatically adjusting damping levels based on whether the track is smooth or bumpy. This logic was developed and perfected across various track types.

Further Weight Reduction in Suspension Components

The front axle features a dual adjustable sway bar made of lightweight carbon fiber, with a short, firm default setting. The rear axle sway bar is steel, with 3-way adjustability and weight-saving hollow tube design. From the default “central” position, it can be adjusted to a harder or softer setting. A carbon fiber shear panel in the rear underbody further enhances driving precision by stiffening the rear structure. Electronically controlled dynamic engine and transmission mounts are retuned for increased agility, high-precision response, and clear feedback.

Additional suspension enhancements include wider front and rear tracks and manually adjustable camber on both axles, allowing for extreme camber settings typically used for maximizing track performance.

Michelin Pilot Sport Cup 2 R MO Tires: Bespoke Grip

Michelin® Pilot Sport Cup 2 R MO tires, custom-developed for the Black Series, are available in two compounds: the standard soft-compound Michelin® Pilot Sport Cup 2 R MO1A and a harder compound (Michelin® Pilot Sport Cup 2 R MO2) for higher track temperatures, available as a retrofit from AMG Performance Centers. 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 Management

For closed-track use with ESP OFF, AMG TRACTION CONTROL provides individual support for managing the Black Series’ immense power without ESP brake intervention. Nine slip settings can be preselected on the live rear axle via a separate adjuster in the center console, allowing drivers to fine-tune assistance levels for their skill and track conditions. Control is managed through engine electronics maps, mirroring GT3 racing car technology, without ESP system intervention.

Level 1 offers maximum safety reserves for wet conditions, while Level 9 permits maximum rear axle slip. Each setting 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 drive slip based on the selected level. When this slip level is reached, the system modulates engine output to maintain acceleration at the specified slip level. The system’s algorithms control both engine drive torque and the electronic differential lock level.

Exclusive Interior: Performance and Luxury

The interior design emphasizes the AMG GT Black Series’ performance focus. Exclusive nappa leather is combined with black DINAMICA microfiber and orange contrasting topstitching. The instrument panel and lightweight door panels are trimmed in black DINAMICA microfiber, with loop pull handles replacing conventional handles. Matte black carbon fiber trim, the Interior Night Package, and further orange contrasting topstitching enhance the sporty ambiance. AMG carbon fiber bucket seats (not available in the USA, Canada, and China) offer low weight and optimal lateral support. In these markets, AMG Performance seats are standard. Silver contrasting topstitching is an optional interior customization.

Digital Displays and AMG-Specific Graphics

The AMG GT Black Series features fully 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 ‘Classic’, ‘Sporty’, and ‘Supersport’ AMG-specific display styles. ‘Supersport’ view includes a central rev counter and additional performance information, such as a ‘shift light’. The multimedia display visualizes vehicle functions, driving assistance systems, and communication systems.

Center Console Display Buttons and AMG Performance Steering Wheel

Innovative color display buttons in the V-shaped center console control transmission logic, suspension, ESP, exhaust system, rear spoiler flap, and start/stop function. TFT display buttons use intuitive symbols and offer tactile feedback, operable even with racing gloves. Rocker switches control drive programs and audio volume.

The AMG Performance steering wheel, adopted from the AMG GT family, features a sporty design, flattened bottom, contoured rim, and intuitive controls. The rim is trimmed in DINAMICA microfiber, and the steering wheel badge features exclusive Black Series lettering and the AMG logo. Aluminum shift paddles enable manual gear changes. Integrated Touch Control buttons manage the instrument cluster and multimedia display. AMG DRIVE UNIT steering wheel buttons include a round controller with an integrated display and two configurable display buttons for direct control of AMG functions, allowing drivers to maintain focus on high-speed driving.
