14 Nov. 2012, Tony Kanaan: Due for market launch from June 2013, the new Mercedes-Benz SLS AMG Coupé Black Series is promising GT3 performance from its AMG 6.2-litre V8, with the maximal power output of 464 kW (631 hp, 622 bhp) at 7400 rpm.

Inspired by the SLS AMG GT3 racing version, the new Mercedes-Benz SLS AMG Coupé Black Series is the fifth Black Series model from the Mercedes-AMG stable, following on from the SLK 55 AMG Black Series (2006), the CLK 63 AMG Black Series (2007), the SL 65 AMG Black Series (2008) and the C 63 AMG Coupé Black Series (2011).

More, at a kerb weight of 1550 kilograms (3417 lb), the high-end super sports car version of the gull-wing Mercedes-Benz comes with the "AMG Lightweight Performance" package, achieving a power/weight ratio of 2.45 kg/hp (5.40 lb/hp, or 2.49 kg/bhp (5.49 lb/bhp), and a 0-100 km/h (62 mph) acceleration time of 3.6 seconds, on the way to a top speed of 315 km/h (195.7 mph).

 Engine

To achieve these figures, the naturally aspirated AMG 6.2-litre V8 engine has been updated to generate its 464 kW (631 hp, 622 bhp) at 7400 rpm, with a maximal torque of 635 Nm (468.5 lb-ft, 64.77 kg-m) at 5500 rpm.

The additional 44 kW (60 hp, 59 bhp) of power in comparison to the 420 kW (571 hp, 563 bhp) of the SLS AMG has been achieved by increasing the maximum engine speed from 7200 to 8000 rpm, with a revised high-speed valve train and modified camshafts, adapted cam geometry and optimised bucket tappets featuring a special coating from the racing world, as well as other modifications of the intake air ducting with an increase of peak pressure.

At this level, only the SLS AMG Coupé Electric Drive comes with a higher maximum output of 552 kW (541 hp, 740 bhp).

Installed as front mid-engine (behind the front axle), the V8 gets a newly designed AMG sports exhaust system, produced in titanium for the first time, with distinctive centre and rear mufflers for a more powerful engine sound.

Thanks to the switch from steel to titanium, the new AMG sports exhaust system comes at just under 17 kilograms (37 lb), or around 13 kilograms (28.6 lb) lighter than its predecessor. The new system keeps the performance-enhancing fan-type exhaust pipes which have been in use to date.

Inline with the house policy, the AMG 6.2-litre V8 engine is hand-built at the AMG hand-finishing section in Affalterbach, Germany. The hand-made quality is confirmed by the black AMG engine badge bearing the engine fitter's signature.

The motor sports division of the luxury German car maker says that other engine enhancements include modified oil bores in the crankshaft, new crankshaft bearings, a new oil pump and high-strength screwed connections for the conrods, optimised water and oil cooling system for the engine and transmission and a special support system with a gas-filled strut, bracing the eight-cylinder engine on the body to reduce load change reactions in fast driving.

 Weight saving

As far as the weight saving measures are concerned, they include the adoption of carbon fibre-reinforced plastic (CRP) to make 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.

In contrast to its 26.6-kg (58.6 lb) counterpart with sand-cast aluminium housing, the carbon-fibre torque tube weighs 13.3 kg (29.3 lb). The CRP drive shaft weighs 4.7 kg (10.4 lb) and... a lithium-ion battery replaces the conventional starter battery, saving a further 8 kg (17.6 lb).

 Transmission

To help in lowering the centre of gravity, the 7-speed AMG SPEEDSHIFT dual clutch transmission (DCT) is installed 10 mm (0.4 in.) lower than in the SLS AMG, and is braced against the body by gas-filled struts to avoid stress cycles.

The dual clutch transmission features four driving modes (C, S, S+ and M). "Sport plus" and "Manual" provide sportier performance than with the SLS AMG and SLS AMG GT models, with an increase in shifting speed and reduced response time to shift commands from the driver.

With the automatic double-declutching function (during down shifting), the throttle blips are more pronounced due to the AMG titanium sports exhaust system.

Also, when the new temporary M mode (in C, S or S+ mode) is selected, the driver can activate manual mode by pressing (from the steering wheel) the "up" or "down" shift paddle.

Additionally, a newly developed, electronically controlled AMG rear-axle differential lock with a shorter rear-axle ratio is integrated in the compact transmission housing, replacing the mechanical variant. The new system can attenuate the vehicle's yaw rate around its vertical axis in slaloms or when changing lane at high speeds, since its electronics respond more sensitively and operate with a variable locking effect in acceleration and deceleration modes.

The standard 3-stage ESP system (with "ESP ON", "ESP SPORT Handling Mode" and "ESP OFF") is tuned to the electronic AMG rear-axle differential lock. The same applies to the RACE START function, which enhances traction when accelerating from a standing start in conjunction with the electronic differential lock.

 Suspension

The suspension of the SLS AMG Coupé Black Series keeps its basic layout with double wishbones all-round in aluminium, adding new developments which include an AMG RIDECONTROL performance suspension with tauter basic tuning and electronically controlled two-stage damping (Sport, Sport+) for individual adjustment to the preferred personal driving style, coil-over spring retainers to enable adjustment of wheel loads for personal race track set-ups, more rigid elastokinematics (50% front / 42% rear axle) for greater stability in fast double bends, increased track width (+20mm front / 24mm rear, 0.8/0.94 in.), and new wheel carriers on front axle as well as new front stabiliser tuning for added grip and reduced roll angle in fast cornering.

The AMG 10-spoke light-alloy wheels come in a light forged design, painted matt black with high-sheen finish, in 10x19 at the front and 12x20 at the rear (with a weight saving of 4.0 kg (8.8 lb).

The newly developed Michelin Pilot Sport Cup 2 sports tyres are 275/35 R 19 at the front and 325/30 R 20 at the rear.

The AMG speed-sensitive steering gets new characteristics and the standard AMG ceramic high-performance brake system has ceramic discs measuring 402 x 39 mm (15.8 x 1.5 in.) at the front and 360 x 32 mm (14.17 in. x 1.26 in.) at the rear.

The German sport division says that the weight savings of the AMG ceramic high-performance composite brake system is around 16 kg (35.3 lb) when compared to a conventional steel/aluminium brake system.

 Design

The SLS AMG Coupé Black Series has wide flared wings with an added width of 13 mm / 0.5 in. (front) and 26 mm / 1.02 in. (rear) on each side, as well as darkened headlamps and black surrounds for the rear lights.

The aerodynamic balance is optimised by the front apron and rear apron with diffuser along with side sill panels in Black Series-specific design (carbon fibre-reinforced plastic front splitter, inserts in the side sills and the rear apron). The enlarged air intakes enhance air inflow into the cooling modules at the front.

As on the SLS AMG GT3, the carbon-fibre bonnet features a central air outlet which helps dissipate engine heat while increasing downforce on the directional front axle. The wing-like cross-fin and the star recess in the radiator grille are finished in high-gloss black to match the mirrors and the fins on the bonnet. The carbon elements fitted along the bottom at the sides continue the line of the carbon-fibre front splitter along to the rear.

An optional AMG Aerodynamics package includes a fixed, adjustable carbon-fibre rear aerofoil in the style of the SLS AMG GT3, instead of the standard-fit aerofoil which extends automatically at speeds of over 120 km/h (75 mph), as well as the AMG solar beam colour (exclusive to the SLS AMG Coupé Black Series) and six other exterior paint finishes from the SLS AMG range.

 Interior

The racing-car interior comes with a choice of two colour variants: Alcantara black or Alcantara black/red. With the latter, the door centre panels and the applications on the centre console and above the glove compartment are finished in red.

The AMG Performance steering wheel has Alcantara all round with a flattened bottom rim section. The top section of the steering wheel features a sporty red 12 o'clock marking. The AMG sports bucket seats are 15 kg (33 lbs) lighter than the standard AMG sports seats and the absence of the COMAND APS multimedia system reduces the vehicle's weight by an additional 6 kg (13.2 lbs). Still, the COMAND APS is available as an ex-factory option.

The optional Bang & Olufsen BeoSound AMG surround sound system, with Dolby Digital 5.1 is developed by Mercedes-Benz and Mercedes-AMG with Danish audio specialist Bang & Olufsen.

The system features a 1000W amplifier and 11 loudspeakers with the distribution of the music signals by the digital sound processor (DSP) according to the selectable seat positions – driver, co-driver or central. All functions are controlled via the optional COMAND APS in a special Bang & Olufsen menu.

Other AMG options include carbon-fibre exterior mirrors, carbon-fibre engine cover, interior carbon-fibre package, infotainment system (incl. COMAND APS, AMG Performance Media and backup camera) and the Media Interface.

Last but not least, official prices should be announced near to market launch, bearing in mind that the Mercedes-Benz SLS Coupé AMG is sold in Europe (French market example) at 199,000 euros and the Mercedes-Benz SLS Coupé GT at 217,000 euros.
