The Heart of the Beast: A Groundbreaking AMG V8 Engine
At the core of the Mercedes-AMG GT Black Series lies a revolutionary engine, a testament to the relentless innovation at Mercedes-AMG. To surpass the already exceptional performance of previous AMG GT models and redefine the super sports car segment, the engine specialists in Affalterbach undertook a comprehensive redevelopment of the esteemed 4.0-liter V8 biturbo unit. Despite its existing reputation for remarkable drivability, power delivery, and torque, the ambition was to achieve a significant power increase, even sharper throttle response, and peak torque figures. This ambitious objective necessitated a radical departure from conventional V8 engine design, culminating in the adoption of a flat-plane crankshaft.
Tobias Moers, former Chairman of the Board at Mercedes-AMG GmbH, aptly described the significance of this achievement: “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.”
Cross-Plane vs. Flat-Plane: A Crankshaft Revolution
The design of a V8 engine offers considerable flexibility in crankshaft configuration, a critical element that profoundly influences engine characteristics. Traditionally, V8 engines employ either a cross-plane or a flat-plane crankshaft. AMG’s previous V8 engines all utilized the cross-plane design, where the crankpins of each cylinder pair are positioned at 90-degree angles. This configuration is renowned for its smooth operation, robust low-end torque, and the signature deep rumble characteristic of a cross-plane V8.
In contrast, the flat-plane crankshaft in the Mercedes-AMG Black Series engine positions all crankpins on a single plane, with a 180-degree offset. This design, resembling an inline four-cylinder engine in its crankshaft layout (albeit with wider crankpins to accommodate two connecting rods each), fundamentally alters the engine’s firing order and gas flow dynamics.
Unleashing Power Through Uniform Gas Columns
The flat-plane V8 engine in the AMG GT Black Series features a firing order of 1-8-2-7 4-5-3-6, alternating between cylinder banks for each ignition. This innovative sequence creates uniformly oscillating gas columns in both the exhaust and intake tracts. These consistent pressure waves harness resonance phenomena to boost engine performance. Furthermore, the flat-plane crankshaft contributes to a significantly more responsive throttle, enhancing the immediacy of power delivery.
The adoption of the flat-plane crankshaft is a key differentiator, contributing to the Mercedes-AMG Black Series engine’s status as the most powerful V8 ever produced by Mercedes-AMG. Designated internally as M178 LS2, this engine, while based on the AMG 4.0-liter V8 biturbo with dry sump lubrication, boasts extensive modifications warranting its new code. It unleashes a colossal 720 hp at 6,700-6,900 rpm and a peak torque of 590 lb-ft, sustained across a broad rev range from 2,000 to 6,000 rpm. New camshafts and exhaust manifolds, tailored to the unique firing order, further optimize gas exchange efficiency.
Enhancements extend to the twin-scroll turbochargers, now equipped with anti-friction bearings, mirroring the top-tier AMG GT 4-Door Coupe, for even quicker response. However, the AMG GT Black Series turbochargers feature larger compressor wheels, elevating the boost pressure to an impressive 24.6 psi, compared to 19.6 psi in the AMG GT R. The engine’s redline is set at 7,200 rpm, and enlarged intercoolers ensure optimal charge-air temperatures are maintained, even under extreme operating conditions. A distinctive black engine badge visually signifies the unique nature of this powertrain.
Performance Figures that Defy Expectations
The bespoke AMG engine imbues the Mercedes-AMG Black Series with a distinct character, evident not only in its raw power but also in its unique and aggressive sound profile. This formidable powertrain translates into breathtaking performance metrics. 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. While its top speed is electronically limited to 202 mph, this velocity is truly intended for controlled racetrack environments.
Optimized 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, mirroring all AMG GT 2-door models, this transmission has been meticulously recalibrated for the AMG GT Black Series. It is engineered to manage the engine’s substantial 590 lb-ft of torque, with shift performance and response time thresholds elevated to meet the rigorous demands of racetrack driving.
The enhancements result in an even more responsive and engaging driving experience. Accelerator and engine responses are sharpened, while drive programs, start-up behavior, and gear changes are all optimized for performance. The Race Start function is further amplified by increased starting revs, more precise wheel slip control, and track-focused high-performance tires. Transmission cooling capacity is upgraded to endure extreme conditions, and gear ratios are subtly adjusted to maximize acceleration and responsiveness.
A carbon fiber ‘torque tube’ connects the engine and transmission, contributing to both structural rigidity and weight reduction. Weighing just 30.6 lbs, it is approximately 40 percent lighter than the aluminum counterpart in other AMG GT models. This component creates a torsionally stiff link between the engine and transmission, enhancing drivetrain responsiveness and contributing to balanced weight distribution. The driveshaft within the torque tube is also constructed from lightweight carbon fiber.
Aerodynamics: Sculpted for Speed and Downforce
Sophisticated aerodynamics play a pivotal role in the AMG GT Black Series’ exceptional driving dynamics and high-speed stability. Mirroring the development approach for the AMG GT R and AMG GT R PRO, aerodynamicists and designers collaborated closely to optimize the car’s aerodynamic profile. The principle of ‘form follows function’ is paramount in the Black Series design, with a clear visual and technical lineage to the AMG GT3 and AMG GT4 racing cars.
The front fascia is dominated by a significantly enlarged radiator air inlet, directly inspired by the AMG GT3 race car. The radiator trim features vertical slats in dark chrome, and the central inlet now feeds air directly to the wheel arch coolers, eliminating the need for outer air inlets in the front bumper. Semicircular flics optimize airflow, increasing downforce at the front axle and improving brake cooling. ‘Air curtains’ manage airflow towards the wheels, working in conjunction with flics to reduce drag and enhance downforce. This design philosophy prioritizes cooling efficiency, minimizes air resistance, and maximizes front-end downforce.
A manually adjustable carbon fiber front splitter offers two settings: ‘Street’ and ‘Race’ (the latter exclusively for racetrack use). In the ‘Race’ position, extending forward, it creates a front diffuser in the shape of an inverted wing profile beneath the front section. This element, influenced by negative pressure at higher speeds, further lowers itself, accelerating underbody airflow and creating a ‘Venturi effect’ that draws the car closer to the road and amplifies front axle downforce. This translates to enhanced steering precision during high-speed cornering and exceptional directional stability.
The carbon fiber hood, another motorsport-derived component, features two large exhaust air outlets finished in black carbon fiber. These vents channel hot air from the diagonally positioned cooling pack out of the engine compartment, increasing overall downforce, reducing air resistance, and optimizing engine cooling airflow. Air is also guided around the A-pillars and side windows to enhance the effectiveness of the rear spoiler. Integrated front fender vents, with five body-colored fins and exhaust air openings behind the wheels, further contribute to front axle downforce through effective wheel arch ventilation. Larger side sill panels with black carbon fiber elements, incorporating vertical blades and integrated cooling air ducts for rear brake cooling, optimize airflow around the vehicle’s flanks.
Two-Stage Rear Spoiler: Adaptive Downforce
The rear view is defined by a new bumper with a large diffuser, rounded twin-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 suit varying track conditions. The lower blade is intentionally compact to optimally interact with airflow from the front of the car. Matte black carbon fiber spoiler supports, meticulously designed through extensive simulations, enhance aerodynamic efficiency. These supports are bolted to the carbon fiber rear hatch, also finished in black.
A key feature is an adjustable flap within the upper spoiler blade. This active aerodynamic element is electronically adjusted by up to 20 degrees, adapting to driving conditions and the selected AMG DYNAMICS mode to optimize longitudinal and transverse dynamics. In a flat position, it minimizes air resistance for maximum speed. In an inclined position, it increases downforce, improving braking and cornering stability.
Four activation strategies are employed, linked to the selected AMG DYNAMICS mode (Basic, Advanced, Pro, or Master). Some strategies incorporate driving dynamics recognition. For example, in Master mode, the flap is permanently inclined up to 155 mph, then retracts to reduce drag for top speed. However, during braking or cornering, it instantly re-extends to maximize downforce. Drivers can also manually control the flap via a button in the center console. Extensive underbody paneling, featuring longitudinal fins, further refines airflow to the rear diffuser, contributing to a downforce level exceeding 882 lbs at 155 mph.
Lightweight Construction: Carbon Fiber Dominance
The Mercedes-AMG Black Series extensively utilizes lightweight carbon fiber and an intelligent material mix to minimize weight and enhance performance. The carbon fiber roof with a lowered center, the carbon fiber rear hatch with a small spoiler lip and lightweight glass rear windshield, and lightweight laminated front windshield glass are all key components. A coiled carbon fiber transmission mount is another exclusive Black Series element.
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 structural rigidity and driving precision. These elements form a connected network, contributing to the Black Series’ exceptional handling. A carbon fiber shear panel under the engine, connected to the integral carrier, further stiffens the front section and steering system, improving steering precision and front axle stability. The integral carrier itself is exclusively designed for the Black Series using lightweight aluminum.
The standard ceramic high-performance compound brake system, featuring black calipers with white lettering, further reduces weight while delivering exceptional braking performance. Special brake pads and rotors, along with optimized brake cooling, ensure consistent and fade-free deceleration. Standard light-alloy forged wheels also contribute to weight savings.
Suspension and Chassis: Precision Engineered for the Track
The Mercedes-AMG Black Series features an AMG coil-over suspension with adjustable spring preload and adaptive adjustable damping, tailored for extreme racetrack use. This motorsport-derived technology is combined with the AMG RIDE CONTROL continuously variable, adaptive damping system, which electronically adjusts damping at each wheel based on driving conditions, speed, and road surface. Two separate valves for rebound and compression forces in the dampers, also motorsport-derived, enable rapid and precise damping modulation. Firmer damping during cornering and braking minimizes body roll. Continuous damping adjustment ensures optimal road contact and safety, even at high speeds.
Drivers can adjust damping characteristics via the AMG DRIVE UNIT or AMG DYNAMIC SELECT modes, choosing between “Comfort”, “Sport”, and “Sport Plus”. “Sport Plus” mode features intelligent track surface recognition, automatically adapting damping levels based on track quality, optimizing performance on both smooth and bumpy circuits.
A dual adjustable sway bar made of lightweight carbon fiber is fitted at the front axle, while the rear axle uses a 3-way adjustable steel sway bar with a hollow tube design for weight savings. A carbon fiber shear panel in the rear underbody further enhances structural rigidity and driving precision. Electronically controlled dynamic engine and transmission mounts are retuned for increased agility and precise feedback. Wider front and rear tracks and manually adjustable camber at both axles allow for extreme camber settings for optimized racetrack performance.
Michelin® Pilot Sport Cup 2 R MO tires, specifically developed for the Black Series, are standard. Available in two compounds – a soft compound (standard) and a harder compound (for higher track temperatures) – these high-performance tires are available exclusively for Mercedes-AMG. 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 Mastery
For racetrack use with ESP OFF, AMG TRACTION CONTROL offers nine levels of adjustable slip control, allowing drivers to fine-tune support and manage the Black Series’ immense power without ESP brake intervention. This system, derived from the AMG GT3 racing car, operates via maps in the engine electronics, without ESP system engagement. A dedicated adjuster on the center console allows for on-the-fly slip adjustment. Level 1 provides maximum safety in wet conditions, while Level 9 allows for maximum rear axle slip. The system anticipates situations using a friction coefficient evaluator and other data, calculating permissible wheel slip and modulating engine output and electronic differential lock to maintain the chosen slip level.
Interior Design: Race-Inspired Luxury
The interior of the Mercedes-AMG Black Series reflects its uncompromising performance focus. Exclusive nappa leather is combined with black DINAMICA microfiber featuring 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 and the Interior Night Package further enhance the sporty ambiance.
AMG carbon fiber bucket seats (standard in some markets, AMG Performance seats in USA, Canada, China) offer exceptional lateral support and lightweight construction. Silver contrasting topstitching is an optional interior trim choice. The digital instrument displays from the AMG GT family, featuring a 12.3-inch instrument cluster and a 10.25-inch multimedia display, offer AMG-specific graphics and display styles (“Classic”, “Sporty”, “Supersport”). The “Supersport” view includes a central rev counter and additional performance information.
Colored display buttons in the center console control transmission logic, suspension, ESP, exhaust system, rear spoiler flap, and start/stop function. These TFT display buttons are intuitive and operable even with racing gloves. The AMG Performance steering wheel, trimmed in DINAMICA microfiber with Black Series lettering, features aluminum shift paddles and integrated Touch Control buttons. AMG DRIVE UNIT steering wheel buttons, including a round controller and configurable display buttons, provide direct access to driving programs and AMG functions.
