Mercedes-AMG has long been synonymous with pushing automotive boundaries, and the GT Black Series is a testament to this relentless pursuit of performance. As the pinnacle of the AMG GT family, the Black Series isn’t just a car; it’s a statement – the most powerful AMG V8 series engine ever crafted, wrapped in the most aggressively aerodynamic and intelligently engineered package imaginable. This is a machine born from motorsport DNA, designed to dominate both the track and the road, embodying the true spirit of the Black Series lineage.
The Black Series Legacy: Motorsport Bred Performance
Since 2006, the Black Series designation at Mercedes-AMG has signified something truly special: uncompromising performance, radical design, and technology directly descended from the racetrack. These are not mere collector’s items; Black Series models are built for exhilarating high-speed driving, engineered for the circuit yet still road-legal. The AMG GT Black Series elevates this tradition, representing the most extreme interpretation of AMG’s performance philosophy.
Revving Redefined: The Heart of the Black Series Beast
At the core of the AMG GT Black Series lies a monumental achievement in engine design. Even with the already formidable reputation of the AMG 4.0-liter V8 biturbo, AMG’s engineers in Affalterbach embarked on a radical redevelopment. The goal was clear: surpass the existing AMG GT flagship in power, throttle response, and torque. This ambition necessitated a fundamental shift – the adoption of a flat-plane crankshaft.
Tobias Moers, former Chairman of the Board at Mercedes-AMG GmbH, described the GT Black Series as “our latest automotive highlight and continues a tradition established in 2006… The performance, appearance and driving dynamics of the GT Black Series are second to none. This project was a fantastic end to my work at AMG.”
Flat-Plane Crankshaft: An Engine Architecture Revolution
The crankshaft configuration is a defining element of a V8 engine, dictating its character and performance. Traditionally, AMG V8 engines have utilized a cross-plane crankshaft, known for its smoothness and robust low-end torque, producing the classic V8 rumble. However, for the GT Black Series, AMG embraced the flat-plane crankshaft design.
In contrast to the cross-plane’s 90-degree crankpin offset, the flat-plane crankshaft aligns all crankpins on a single plane with a 180-degree offset, resembling an inline four-cylinder in its firing order. This configuration yields uniformly oscillating gas columns in both the exhaust and intake systems. This resonance is expertly harnessed to amplify power output and sharpen throttle response significantly.
M178 LS2: The Most Potent AMG V8 Ever
While rooted in the AMG 4.0-liter V8 biturbo architecture with dry-sump lubrication, the engine powering the GT Black Series is designated the new internal code M178 LS2, reflecting its extensive modifications. This powerhouse unleashes a staggering 720 hp between 6,700 and 6,900 rpm, and a colossal 590 lb-ft of torque from 2,000 to 6,000 rpm. Bespoke camshafts and exhaust manifolds, tailored to the flat-plane crankshaft’s firing order, further optimize gas flow.
Mirroring the AMG GT 4-Door Coupe’s top-tier models, the twin-scroll turbochargers are fitted with anti-friction bearings for enhanced responsiveness. However, the GT Black Series turbos feature larger compressor wheels, boosting peak charge pressure to 24.6 psi, a notable increase over the AMG GT R’s 19.6 psi. The redline is elevated to 7,200 rpm, and enlarged intercoolers ensure optimal charge-air temperatures are maintained. A black-finished engine badge uniquely identifies this groundbreaking AMG powerplant.
Performance Unleashed: Blistering Speed and Acceleration
The M178 LS2 engine imbues the AMG GT Black Series with an unparalleled character, not only in raw power delivery but also in its distinctive, high-frequency sound signature. This translates to breathtaking performance figures: 0 to 60 mph in a mere 3.1 seconds, and 0 to 124 mph (200 km/h) in under nine seconds. The top speed is electronically limited to 202 mph, a velocity best reserved for closed circuits.
AMG SPEEDSHIFT DCT 7-Speed Transmission: Optimized 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 ideal weight distribution, a hallmark of AMG GT 2-door models. This transmission has been meticulously recalibrated for the AMG GT Black Series, engineered to manage the increased torque output. Shift speeds and response times have been sharpened for peak track performance.
The transmission’s modifications extend to drive programs, start-up behavior, and gear changes, all contributing to heightened agility. The Race Start function is now even more aggressive, featuring elevated starting revs, refined wheel slip control, and track-focused high-performance tires. Enhanced transmission cooling and subtly revised gear ratios further bolster its track prowess.
A carbon fiber torque tube, 40% lighter than the aluminum counterpart in other AMG GT models, connects the engine and transmission, enhancing torsional rigidity and contributing to balanced weight distribution. The lightweight carbon fiber driveshaft further minimizes rotational inertia.
Aerodynamic Mastery: Sculpted for Speed and Downforce
Sophisticated aerodynamics are paramount to the AMG GT Black Series’ dynamic capabilities and high-speed stability. Drawing heavily from the AMG GT3 and GT4 racing programs, AMG’s aerodynamicists and designers collaborated to sculpt the car’s form strictly according to function.
The front fascia is dominated by a significantly enlarged radiator air inlet, directly adopted from the AMG GT3 race car. Vertical slats in dark chrome adorn the radiator trim, and the central inlet now feeds air directly to the wheel arch coolers, eliminating the need for additional outer air inlets in the front bumper. Semicircular flics optimize airflow, increasing front axle downforce and improving brake cooling. Air curtains manage airflow towards the wheels, working in concert with the flics to reduce drag and enhance downforce. The redesigned front end maximizes cooling efficiency while minimizing drag and increasing downforce.
A two-stage adjustable carbon fiber front splitter (Street and Race modes) adapts to varying track demands. In Race position, it extends forward, creating a reversed wing profile front diffuser. This element generates a Venturi effect, drawing the car closer to the road and significantly boosting front axle downforce, enhancing steering precision and directional stability, particularly in high-speed corners.
The carbon fiber hood features two prominent black-finished carbon fiber exhaust air outlets, channeling hot air from the diagonally positioned cooling pack out of the engine bay. This motorsport-derived technology increases overall downforce and reduces drag while optimizing engine cooling airflow. Air is directed around the A-pillars and side windows to enhance the effectiveness of the rear spoiler. Integrated front fender vents with body-colored fins and carbon fiber fender exhaust air openings behind the front wheels further augment front axle downforce through efficient wheel arch ventilation. Larger, wider side sill panels with black carbon fiber elements, incorporating rear brake cooling ducts, optimize airflow around the vehicle.
The rear profile is defined by a new bumper with a substantial diffuser, twin rounded exhaust outlets, side wheel arch ventilation, and an innovative two-stage rear spoiler. Both spoiler blades are crafted from carbon fiber and mechanically adjustable for track-specific optimization. The lower blade is intentionally compact to effectively interact with incoming airflow. Matte black carbon fiber spoiler supports, meticulously designed through simulations, enhance aerodynamic efficiency.
A key aerodynamic element is the adjustable flap integrated into the upper spoiler blade. Electronically controlled and adjustable by 20 degrees based on driving situation and AMG DYNAMICS mode, it optimizes both longitudinal and lateral dynamics. In a flat position, it minimizes drag for top speed runs. In the inclined position, it boosts braking and cornering stability via increased rear axle downforce. Four activation strategies are linked to AMG DYNAMICS modes, with automatic adjustments based on speed, braking, and cornering, or manual control via a center console button.
Extensive underbody paneling, incorporating longitudinal fins, ensures optimized airflow to the rear diffuser, accelerating airflow and significantly increasing downforce. This comprehensive aerodynamic package generates over 882 lbs of downforce at 155 mph.
Lightweight Engineering: Carbon Fiber and Intelligent Material Mix
The AMG GT Black Series employs an intelligent material mix and lightweight construction throughout. A carbon fiber roof with a lowered center, a carbon fiber rear hatch, and lightweight glass for the rear windshield are key components. 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, underbody, and rear, along with a lightweight integral carrier and carbon fiber cross tunnel, stiffen the aluminum body shell, enhancing structural rigidity and driving precision. The front axle integral carrier is uniquely constructed from lightweight aluminum for the Black Series.
Standard ceramic high-performance compound brakes with black calipers and white lettering offer exceptional stopping power with reduced weight. Lightweight forged alloy wheels further contribute to weight reduction.

The AMG GT Black Series features an AMG coil-over suspension with adjustable spring preload and adaptive adjustable damping, tuned for extreme track use. Motorsport-derived 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. New valves in the dampers react rapidly to suspension movements. Damping characteristics adjust continuously with speed, ensuring optimal road contact and safety, even at high velocities.
Three damping modes are selectable: “Comfort,” “Sport,” and “Sport Plus.” “Sport Plus” mode intelligently adapts to track surface quality, automatically adjusting damping levels for optimal performance on various circuits, from smooth Grand Prix tracks to bumpy circuits like the Nürburgring Nordschleife.
A dual adjustable carbon fiber front sway bar and a 3-way adjustable steel rear sway bar further refine handling. Electronically controlled dynamic engine and transmission mounts are retuned for enhanced agility and feedback. Wider front and rear tracks and manually adjustable camber allow for motorsport-derived camber settings for closed-track performance optimization.
Michelin® Pilot Sport Cup 2 R MO tires, custom-developed for the Black Series, are available in two compounds. The standard soft-compound MO1A tire features sidewall enhancements that complement the AMG GT Black Series silhouette. A harder compound MO2 is available for hotter track conditions. Tire sizes are 285/35 ZR 19 front and 335/30 ZR 20 rear.
AMG TRACTION CONTROL: Nine Levels of Grip Mastery
For track use with ESP OFF, AMG TRACTION CONTROL provides nine levels of adjustable slip control on the rear axle, offering tailored support without ESP brake intervention. Controlled via a central console adjuster, it allows drivers to fine-tune assistance for varying conditions. Level 1 offers maximum safety in wet conditions, while Level 9 permits maximum rear axle slip. The system anticipates situations using a friction coefficient evaluator, modulating engine output and the electronic differential lock to maintain the selected slip level.
