The Heart of the Beast: A Distinctive V8 Engine Design
The architecture of a V8 engine offers engineers considerable flexibility in crankshaft design, a critical factor influencing engine characteristics. Typically, V8 engines employ one of two crankshaft configurations: the ‘cross-plane’ crankshaft, with crankpins positioned at 90-degree intervals, a design historically favored by AMG, or the ‘flat-plane crankshaft,’ where all crankpins lie on a single plane with a 180-degree offset.

Visually, a cross-plane crankshaft exhibits a cross shape when viewed from the front, hence its name. Its advantages include exceptional smoothness and robust low-end torque, accompanied by the signature deep rumble associated with cross-plane V8 engines. To optimize the 4.0-liter V8 biturbo’s potential, AMG engineers strategically positioned the exhaust side within the engine’s “hot V,” the inner space between the two cylinder banks.
Unleashing Power: Uniformly Oscillating Gas Columns
The flat-plane crankshaft represents another avenue for boosting engine performance. In a flat-plane V8, the configuration resembles an inline four-cylinder engine, albeit with wider crankpins accommodating two connecting rods each. Ignition in a flat-plane V8 alternates between cylinder banks, further enhancing the gas cycle. The unique firing order, characterized by a 180-degree crankshaft angle offset (1-8-2-7 4-5-3-6), creates uniformly oscillating gas columns in both the exhaust and intake tracts. This resonance effect is expertly harnessed to amplify engine power. Furthermore, the flat-plane design contributes to a noticeably more responsive throttle.
The Most Powerful AMG V8 to Date
While rooted in the AMG 4.0-liter V8 biturbo architecture with dry sump lubrication, the AMG GT Black Series engine is designated with a new internal code: M178 LS2, reflecting its extensive modifications. This powerhouse churns out an astounding 720 horsepower at 6,700-6,900 rpm and a peak torque of 590 lb-ft, sustained from 2,000 to 6,000 rpm. New camshafts and exhaust manifolds, tailored to the unique firing order, further optimize the engine’s gas exchange.

Mirroring the top-tier AMG GT 4-Door Coupe, the twin-scroll exhaust turbochargers are mounted on anti-friction bearings, enhancing throttle response. However, the GT Black Series turbochargers feature larger compressor wheels, allowing them to deliver a boosted pressure of 24.6 psi, a significant increase compared to the AMG GT R’s 19.6 psi. The engine’s redline is set at 7,200 rpm, reflecting its high-performance nature. Larger intercoolers ensure optimal charge-air temperatures are maintained. A distinctive black engine badge visually distinguishes this unique powerplant.
Performance Unleashed: 0-124 mph in Under Nine Seconds
The bespoke Handcrafted AMG engine in the GT Black Series endows it with a distinct character, evident not only in its power delivery but also in its unique and aggressive sound. This formidable engine translates to breathtaking performance figures: the Black Series accelerates 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 is truly territory best explored on closed racetracks.
Modified AMG SPEEDSHIFT DCT 7-Speed Transmission
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 ideal weight distribution, a common feature across AMG GT 2-door models. This transmission has been specifically tuned for the AMG GT Black Series to handle the increased torque output of 590 lb-ft and optimized for track performance.

Shift performance and response times have been sharpened, making them even more suitable for racetrack demands. The drive programs, start-up characteristics, and gear changes are all enhanced for agility. The Race Start function is now even more potent thanks to higher starting revs, more sensitive wheel slip control, and the use of high-performance track-ready tires. Transmission cooling has been upgraded to meet tougher demands, and transmission ratios have been subtly adjusted.
A carbon fiber ‘torque tube’ connects the engine and transmission, offering exceptional torsional stiffness and contributing to balanced weight distribution. This component is 40 percent lighter than its aluminum counterpart in other AMG GT models, further enhancing driving dynamics. The driveshaft within the torque tube is also constructed from lightweight carbon fiber.
Sophisticated Aerodynamics for Unrivaled Driving Dynamics
Advanced and meticulously optimized aerodynamics are crucial for the AMG GT Black Series’ agile handling and high-speed stability on demanding circuits. Aerodynamicists and designers collaborated closely, building upon the foundations laid by the AMG GT R and AMG GT R PRO. “Form follows function” is the guiding principle behind the Black Series’ aerodynamic enhancements, drawing heavily from the AMG GT3 and AMG GT4 racing cars.
The similarities are immediately apparent, starting with the significantly enlarged radiator air inlet, directly derived from the AMG GT3 race car. The radiator grille features vertical slats in dark chrome, and the wheel arch coolers are now fed directly via the central inlet, eliminating the need for additional outer air inlets in the front bumper. Semicircular flics optimize airflow, increasing front axle downforce and enhancing brake cooling. ‘Air curtains’ manage airflow towards the wheels, working in tandem with the flics to reduce drag and increase downforce. This new design philosophy prioritizes cool-air efficiency, minimizes air resistance, and maximizes front-end downforce.
The adjustable carbon-fiber front splitter offers two settings: Street and Race (for track use only). In Race position, it extends forward, creating a front diffuser with a reversed wing profile underneath the front section. This element further lowers itself with increasing speed due to negative pressure, accelerating underbody airflow and generating a ‘Venturi effect,’ which pulls the car closer to the road and boosts front axle downforce. Drivers will experience enhanced steering precision during high-speed cornering and exceptional directional stability. With the front diffuser in Race position, the new rear spoiler design further amplifies rear axle downforce.
Motorsport-Derived Aero Elements: Hood and Rear Wing
Another direct motorsport influence is the carbon-fiber hood, featuring two prominent exhaust air outlets finished in black carbon fiber. These outlets channel hot air from the diagonally positioned cooling pack out of the engine compartment, a technology directly borrowed from racing. This design increases overall downforce while reducing air resistance and optimizing engine cooling airflow. Air is also strategically guided around the A-pillars and side windows to enhance the effectiveness of the new rear spoiler. Seamlessly integrated front fender vents and carbon-fiber fender air outlets further contribute to front axle downforce through effective wheel arch ventilation. Larger and wider side sill panels with black carbon-fiber elements, incorporating brake cooling ducts for the rear axle, further optimize airflow around the vehicle.

The rear is defined by a new bumper with a large diffuser, 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 various track conditions. The lower blade is intentionally compact to optimize airflow from the front. Matte black carbon-fiber spoiler supports, meticulously designed through 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, an active aerodynamic element electronically adjusted up to 20 degrees based on driving situation and AMG DYNAMICS mode. In a flat position, it minimizes air resistance for top speed. In an inclined position, it enhances braking and cornering stability via increased rear downforce. Four activation strategies are available, linked to AMG DYNAMICS modes (Basic, Advanced, Pro, Master), with some incorporating driving dynamics recognition. For instance, in Master mode, the flap is permanently inclined up to 155 mph, retracting above that speed to reduce drag, but instantly redeploying during braking or cornering for optimized performance. Drivers can also manually control the flap via a center console button.
Underbody Paneling and Lightweight Construction
Extensive underbody paneling contributes to aerodynamic efficiency and thermal management. The flat underbody incorporates longitudinal fins precisely optimized to channel airflow to the rear diffuser, accelerating airflow and significantly increasing downforce. This comprehensive aerodynamic package, working in concert with the rear spoiler, generates over 882 lbs of downforce at 155 mph.
Lightweight carbon fiber is employed throughout the vehicle, from the roof and rear hatch to the transmission mount and shear panels. This ‘intelligent material mix’ and ‘lightweight construction’ philosophy extends to lightweight glass for the windshield and rear window. 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 driving precision. The front integral carrier is exclusively designed for the Black Series using lightweight aluminum.
Standard ceramic high-performance compound brakes with black calipers and white lettering offer exceptional stopping power and low weight. Special brake pads and rotors, along with optimized brake cooling, ensure consistent deceleration and precise brake modulation. Light-alloy forged wheels further contribute to weight reduction.
AMG Coil-Over Suspension and Track-Focused Chassis
An AMG coil-over suspension with adjustable spring preload and adaptive adjustable damping, derived from motorsport technology, is standard. The double wishbone suspension design ensures high camber and toe-in stability, enabling high cornering speeds and optimized driver feedback at the limits. Forged aluminum wishbones, steering knuckles, and hub carriers reduce unsprung mass. Spherical bearings on the rear axle wishbones, directly from motorsport, eliminate play and maintain consistent toe-in and camber under high loads, resulting in precise steering and enhanced cornering performance.
The AMG RIDE CONTROL continuously variable adaptive damping system electronically adjusts damping at each wheel based on driving conditions, speed, and road surface. New valves in the dampers, also motorsport-derived, react quickly to suspension movements. Three damping modes are available: “Comfort,” “Sport,” and “Sport Plus,” selectable via the AMG DRIVE UNIT or AMG DYNAMIC SELECT. ‘Sport Plus’ mode intelligently adapts damping based on track surface quality, optimizing performance on both smooth and bumpy circuits.
Carbon fiber is further utilized in the dual adjustable front sway bar, while the rear sway bar is a 3-way adjustable steel design, saving weight with a hollow tube construction. Electronically controlled dynamic engine and transmission mounts are retuned for increased agility and precise response. Wide front and rear tracks and manually adjustable camber allow for extreme camber settings for track use.
Specially developed Michelin® Pilot Sport Cup 2 R MO tires, available in soft and hard compounds, are standard, sized 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 track use with ESP OFF, AMG TRACTION CONTROL provides nine levels of adjustable slip control on the rear axle, allowing drivers to fine-tune assistance without ESP brake intervention. Controlled via a dedicated adjuster on the center console, the system uses sophisticated algorithms and friction coefficient evaluation to modulate engine output and control the electronic differential lock, optimizing traction for various conditions. Level 1 offers maximum safety in wet conditions, while Level 9 allows maximum rear axle slip.
Exclusive Interior and Advanced Technology
The interior of the AMG GT Black Series reflects its performance focus with exclusive nappa leather and black DINAMICA microfiber with orange contrasting topstitching. The instrument panel and lightweight door panels are trimmed in 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 (in markets where available) or AMG Performance seats (standard in USA, Canada, China) offer optimal support.
