At Mercedes-AMG, the Black Series has been synonymous with a very special type of car since 2006: uncompromisingly sporty, with an expressive design and the most consistent technology transfer from motorsport to series production. Black Series models are exclusive automotive rarities. They have not been developed to gather dust in collectors’ garages, but for high-speed use on race tracks, despite being approved for roads. The AMG GT Black Series represents a new highlight in this tradition: It is the most powerful Mercedes-AMG with a V8 series engine and can thus be individually adapted to the special conditions of various race tracks in a more versatile way than ever before.
In order to emphasise the redefinition of the super sports car, the engine specialists in Affalterbach have once again extensively further developed the tried-and-tested 4.0-litre V8 biturbo unit – in addition to it already being renowned for excellent driveability, power delivery and torque progression. The specifications were clear: Significantly more power than the previous flagship model of the AMG GT family, an even more agile throttle response, maximum torque – all of which meant that a radical change was needed in the form of a new, ‘flat’ crankshaft.
The new GT Black Series engine is based on the AMG 4.0-litre V8 biturbo engine with dry sump lubrication, but it has been given the new internal code M178 LS2 due to the numerous modifications. It achieves 720bhp at 6,700-6,900 rpm and delivers a maximum torque of 800Nm at 2,000-6,000 rpm. New camshafts and exhaust manifolds are adapted to the new firing order and improve the gas cycle further.
Both twin scroll exhaust turbochargers are mounted in anti-friction bearings, as in the top-of-the-range four-door AMG GT Coupé, which optimises their throttle response even further. However, in the Black Series, the turbochargers have been given a larger compressor wheel, meaning that both can deliver a total of 1100 kg air per hour. And the larger intercoolers guarantee that they always keep the charge-air temperature within the best possible range. The unique standing of the new engine is also reflected in the engine badge, which is kept in black.
What does the engine do for the AMG GT Black Series? It gives it a completely independent character, which is not only reflected in the type of power delivery, but also in its very particular sound pattern. And it enables highly impressive driving performance: the two-door vehicle shoots from 0 to 100 kmph in 3.2 seconds, and to 200 kmph in under nine seconds. The top speed is 325kmph, although only on cordoned-off racetracks.
Power is transmitted to the rear wheels via the seven-speed AMG SPEEDSHIFT DCT 7G dual clutch transmission, which is located on the rear axle in a transaxle arrangement for optimal weight distribution, as is the case for all AMG GT models. It has been modified for use in the AMG GT Black Series and adapted to the increased torque of 800 Nm. The previous limits governing shift performance and response time have been extended, making them more suitable for racetracks.
The similarity to the AMG GT3 and AMG GT4 racing cars is visually and technically stronger than ever before. It starts already with the new, significantly larger cooling air inlet grille, which stems directly from the AMG GT3 racing car. The radiator trim has vertical struts in dark chrome. Because the wheel arch coolers are now also supplied with air directly via the central intake, there is no longer a need for the two additional outer air inlets in the front apron. Sickle-shaped flics optimise the flow of air here, which not only increases downforce at the front axle, but also improves brake cooling. The ‘air curtains’ control and direct the flow towards the wheels. Together with the flics in front of the wheels, this serves to reduce the drag coefficient and increase downforce. The new design language therefore combines maximum cool air efficiency with lower air resistance and an increased level of downforce at the front.
The AMG GT Black Series features the fully digital instrument displays from the AMG GT family with an instrument cluster measuring 12.3 inches in front of the driver, and a 10.25-inch multimedia monitor on the centre console. The instrument cluster offers different designs with the three AMG-specific display styles: ‘Classic’, ‘Sporty’ or ‘Supersport’. The ‘Supersport’ view with a central rev counter features extensive additional information, such as a prompt to shift up in manual transmission mode, the ‘shift light’. The visualisations on the multimedia display enable further vehicle functions to be experienced, e.g. with animated presentations of the driving assistance, vehicle and communication systems.
