Mercedes-AMG presents the high-end super sports car version of the gull-wing model, the new SLS AMG Coupé Black Series. Inspired by the SLS AMG GT3 racing version, the fifth Black Series model from Mercedes-AMG boasts a fascinating mix of breath-taking design, outstanding driving dynamics and uncompromising lightweight construction in accordance with the "AMG Lightweight Performance" strategy. With a DIN kerb weight of 1550 kilograms, the SLS AMG Black Series achieves a power/weight ratio of 2.45 kg/hp. The AMG 6.3-litre V8 engine generates a power output of 631 hp at 7400 rpm and accelerates the most dynamic gull-wing model of all time to 62 mph in 3.6 seconds. The coil-over AMG RIDE CONTROL performance suspension, the AMG ceramic high-performance composite brake system and the weight-optimised forged AMG light-alloy wheels with newly developed sports tyres combine with the electronically controlled AMG rear-axle differential lock and the AMG SPEEDSHIFT DCT 7-speed sports transmission featuring an uncompromisingly emotional shift and response times to raise the SLS AMG Black Seriesto a new level. The AMG Aerodynamics package is optionally available to further boost the vehicle's driving dynamics.
Black Series - a name that resonates with automobile experts and enthusiasts. Following on from the SLK 55 AMG Black Series from 2006, the CLK 63 AMG Black Series (2007), the SL 65 AMG Black Series (2008) and the C 63 AMG Coupé Black Series (2011), the fifth exponent sees the Black Series entering a new dimension with the gull-wing model.
"The new SLS AMG Coupé Black Series is a perfect study in the one hundred percent transfer of technology and engineering from motorsport to the road. We have drawn inspiration from the worldwide success of the SLS AMG GT3 customer sport racing car on both a conceptual and a technological level. Boasting numerous lightweight components and fantastic driving dynamics, our fifth Black Series model guarantees pure, unadulterated 'Driving Performance'. The SLS AMG Coupé Black Series is the ultimate choice for fast laps and highly emotional driving experiences", says Ola Kallenius, Chairman of Mercedes-AMG GmbH.
"The most dynamic gull-wing model of all time goes by the name of the SLS AMG Coupé Black Series. Fans of high-performance super sports cars will be fascinated by its high-tech package. The basis for passionate performance and supreme driving dynamics is provided by numerous new developments in the area of the engine, power transmission, suspension and aerodynamics - also according top priority to our "AMG Lightweight Performance" strategy. Great efforts in the field of lightweight design have resulted in a DIN kerb weight of 1550 kilograms," notes Tobias Moers, head of overall vehicle development and member of the management board of Mercedes-AMG GmbH.
The uprated AMG 6.3-litre V8 engine generating a power output of 631 hp and 635 Newton metres of torque is a byword for thrilling driving dynamics, making the SLS AMG Coupé Black Series the most powerful AMG high-performance automobile with a combustion engine at present. Only the SLS AMG Coupé Electric Drive with a maximum output of 552 kW comes with greater power reserves.
The SLS AMG Coupé Black Series accelerates to 100 km/h in 3.6 seconds. The top speed stands at 315 km/h. The additional 60 hp of power in comparison to the 571 hp offered by the SLS AMG has been achieved by the following measures:
The eight-cylinder naturally aspirated engine installed as a front mid-engine behind the front axle boasts racing car-style responses and livelier than ever revving ability. The powerful AMG V8 engine's race track aspirations are also apparent in its sound: the newly designed AMG sports exhaust system, produced in titanium for the first time, features distinctive centre and rear mufflers which result in a more powerful and even more striking engine sound. The switch from steel to titanium has spawned substantial weight savings: at just under 17 kilograms, the new AMG sports exhaust system is around 13 kilograms lighter than its predecessor. The new system features the performance-enhancing fan-type exhaust pipes which have been in use to date.
Lightweight at its core: with a kerb weight of 1550 kilograms (DIN), the new SLS AMG Coupé Black Series is not only 70 kilograms lighter than the SLS AMG, but also attains the best power/weight ratio of all AMG Black Series vehicles to date by far. The figure of 2.45 kg/hp will also bear up to comparison in the super sports car scene. Such a ratio is made possible by systematic application of the "AMG Lightweight Performance" strategy. Numerous body elements, such as the bonnet, the rear panel behind the AMG sports bucket seats, the diagonal braces on the underbody and the torque tube between engine and transmission consist entirely of the motorsport material carbon fibre (carbon fibre-reinforced plastic). In contrast to its 26.6-kilogram counterpart with sand-cast aluminium housing, the carbon-fibre torque tube weighs only 13.3 kilograms. As previously, power transmission between the engine and the dual clutch transmission (transaxle principle) which is flange-mounted on the rear axle is effected by means of a carbon fibre-reinforced plastic (CRP) drive shaft weighing only 4.7 kilograms. A number of parts on the aluminium spaceframe have also been replaced by CRP components. A lithium-ion battery which is used in place of the conventional starter battery saves a further eight kilograms.
The overall power transmission system is also a major contributory factor to the outstanding driving dynamics of the SLS AMG Coupé Black Series. The AMG SPEEDSHIFT DCT 7-speed sports transmission is installed ten millimetres lower in order to achieve a lower centre of gravity for the vehicle and is braced against the body by gas-filled struts in order to avoid stress cycles. The dual clutch transmission features four driving modes (C, S, S+ and M). "Sport plus" and "Manual" in particular provide for markedly sportier performance than with the SLS AMG and SLS AMG GT models. In addition to an increase in shifting speed, the reduced response time to shift commands from the driver and the shifting hardness provide pure dynamism.
An even more thrilling feature is the automatic double-declutching function during downshifting: the throttle blips when shifting gear are more pronounced and more strikingly audible than ever, due to the AMG titanium sports exhaust system. There is also a new temporary M mode. In C, S or S+ mode, this enables the driver to activate manual mode without having to remove a hand from the steering wheel, by pressing the "up" or "down" shift paddle once. In temporary M mode the driver experiences the dynamism and performance of gear-shifting in manual mode in all of the automatic driving programmes, with automatic up- and down-shifting into the bargain. This allows the driver to devote his full attention to the vehicle's impressive performance.
A newly developed, electronically controlled AMG rear-axle differential lock with a shorter rear-axle ratio replaces the mechanical variant; it is integrated in the compact transmission housing. This system operates with a variable locking effect in acceleration and deceleration mode; in addition, the electronics respond more sensitively than to date, enabling excellent traction for the driven wheels at all friction levels. The electronic AMG rear-axle differential lock also benefits driving safety: in slaloms or when changing lane at high speeds the system has a stabilising effect, as it is able to attenuate the vehicle's yaw rate around its vertical axis. The standard-fit 3-stage ESP system featuring the functions "ESP ON", "ESP SPORT Handling Mode" and "ESP OFF" is precision-tuned to the electronic AMG rear-axle differential lock. The same applies to the RACE START function, which provides for perfect traction when accelerating from a standing start in conjunction with the electronic differential lock.
The chassis and suspension of the SLS AMG Coupé Black Series are also new. The basic layout with double wishbones all-round in aluminium remains unchanged, but barely a component has gone untouched in the interests of much enhanced race track performance.
