AMG 6.3-liter V8 engine – synonymous with thrilling driving dynamics
The uprated AMG 6.3-liter V8 engine generating a power output of 622 hp and 468 lb-ft of torque is a synonym for thrilling driving dynamics, making the 2014MY SLS AMG Black Series the most powerful AMG high-performance automobile with a combustion engine. Only the SLS AMG Electric Drive with a maximum output of 740 hp has more power.
The 2014MY SLS AMG Black Series accelerates to 60 mph in just 3.5 seconds, and onward to a top speed of 196 mph. The additional 39 hp of power compared to the 583 hp delivered by the
SLS AMG GT is courtesy of the following enhancements:
-Increase in maximum engine speed from 7,200 to 8,000 rpm
-Fully revised high-speed valve train with modified camshafts, adapted cam geometry and optimized bucket tappets featuring a special coating that is typically used on race vehicles -Modification of the intake air ducting: de-throttling and adaptation tomatch the new maximum engine speed
-Adaptation of the engine mapping and increase in peak pressure
The engineers at Mercedes-AMG have further optimized the crank assembly in the interests of optimum stability under tough race track conditions. The measures include modified oil bores in the crankshaft, new crankshaft bearings, a new oil pump and high-strength screw fasteners for the connecting rods. The entire water and oil cooling system for the engine and transmission has been optimized further. The AMG V8 engine in the SLS AMG Black Series also has an additional specialized mounting system. A gas-filled strut braces the eight-cylinder engine against the body, effectively eliminating undesired load shifts during highly-dynamic race-track driving. The AMG 6.3-liter V8 engine is hand-built in the AMG factory in Affalterbach, in line with the philosophy “one man, one engine.” This hand-made quality is confirmed by the black AMG engine badge bearing the signature of the engine builder, which is a hallmark of the Black Series models.
The key data at a glance:
SLS AMG Black Series
-Displacement: 6,208 cc
-Bore x stroke: 4.02 x 3.72 inches
-Compression ratio: 11.3 : 1
-Output: 622 hp at 7,400 rpm
-Max. torque: 468 lb-ft at 5,500 rpm
-Maximum engine speed: 8,000 rpm
-Engine weight (dry): 452 lbs
-Acceleration 0-60 mph: 3.5 s
-Top speed: 196 mph
The eight-cylinder naturally aspirated engine installed with a front mid-engine layout behind the front axle, and boasts racing car responses and an exceptional level of high-revving performance. The racetrack credentials of thepowerful AMG V8 engine are also apparent from its sound: the newly designed AMG sport exhaust system, produced for the first time in titanium, features distinctive center and rear mufflers, delivering a more powerful and even more striking engine sound. The switch from steel to titanium has spawned substantial weight savings: at just under 37.5 pounds, the new AMG sports exhaust system is around 28.7 pounds lighter than its predecessor. The new system features performance-enhancing, fan-type exhaust manifolds.
Systematic application of the AMG Lightweight Performance strategy
With a curb weight of 3,417 pounds, the 2014MY SLS AMG Black Series is not only 154 pounds lighter than the SLS AMG, but also attains the best power/weight ratio by far of all AMG Black Series vehicles to date. Even among super sports cars, the figure of 5.49 lb/hp is extremely competitive and made possible by consistent application of the “AMG Lightweight Performance” strategy. Numerous body elements, such as the hood, the rear panel behind the AMG sports bucket seats, the diagonal braces on the underbody and the torque tube between engine and transmission are made entirely from CFRP (carbon-fiber reinforced plastic). In contrast to its 58.6-pound counterpart with a sand-cast aluminum housing, the carbon-fiber torque tube weighs just 29.3 pounds. As before, a CFRP drive shaft weighing just 10.4 pounds handles power transmission between the engine and dual-clutch transmission (transaxle principle), which is flange-mounted on the rear axle. CFRP components also replace a number of parts of the aluminum spaceframe, while a lithium-ion battery takes on the role of the conventional starter battery, saving a further 17.6 pounds.
Dual-clutch transmission for even smoother performance
The AMG SPEEDSHIFT DCT 7-speed sports transmission is installed 0.4 inches lower in order to give the vehicle a lower center of gravity and is braced against the body by gas-filled struts to avoid stress cycling. The dual-clutch transmission features four drive modes (C, S, S+ and M). “Sport plus” and “Manual” deliver even more aggressive performance than in the SLS AMG and SLS AMG GT models. In addition to an increase in shift speed, the transmission also has reduced response time to shift commands from the driver.
An even more thrilling feature is the automatic rev-matching function during downshifting: the throttle blips when shifting gears are more pronounced and more striking 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 taking a hand from the steering wheel, bypressing 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 programs, with automatic up and down-shifting as well. This allows the driver to devote his full attention to the vehicle’s impressive performance.
New electronic AMG rear-axle differential lock
A new electronically controlled AMG rear-axle differential lock with a shorter rear axle ratio replaces the mechanical variant. Integrated into the compact transmission housing, this system operates with a variable locking effect under acceleration and deceleration. In addition, the electronics are now more responsive, enabling excellent traction for the rear wheels under all roadconditions. The electronic AMG rear-axle differential lock also benefits safety. By reducing the vehicle’s yaw around its vertical axis, the system provides a stabilizing effect in slaloms or when changing lane at high speeds. The standard 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 works with the electronic differential lock to provide perfect traction when accelerating from a standing start.
AMG Adaptive Performance Suspension and sports tires
The chassis and suspension of the 2014 SLS AMG Black Series are also new. The basic layout with aluminum double wishbones at all four corners remains unchanged, but virtually every single component has been refined for significantly enhanced track performance.
The new developments in detail:
-AMG Adaptive Performance Suspension with tauter base setup and electronically controlled two-stage damping (Sport, Sport +) for individual adjustment to suit personal driving style
-Coil-over spring suspension allows for adjusting wheel loads to individual race track setups
-Elastokinematics 50 / 42% more rigid (front/rear axle) for greater stability in turns
-Track width increased by 0.8 / 0.9 inches (front/rear axle) for added grip
-New wheel mounts on front axle and new front stabilizer tuning for addedgrip, reduced body roll in fast cornering
-AMG 10-spoke forged alloy wheels, in very lightweight forged design for optimum strength, painted matte black with high-gloss finish, dimensions: 10×19 front; 12×20 rear. Weight saving: 8.8 pounds
-Newly developed Michelin Pilot Sport Cup 2 sports tires. Dimensions 275/35 R 19 front and 325/30 R 20 rear, for added grip and cornering at the limit
-AMG speed-sensitive steering with revised power steering characteristics for optimum steering precision and outstanding control
Standard AMG high-performance ceramic two-piece brake system
The brake system on the SLS AMG Black Series boasts excellent deceleration performance and outstanding stability. The standard AMG high-performance ceramic two-piece brake system measures 15.8 x 1.5 inches at the front and 14.2 x 1.3 inches at the rear, and feature increased hardness for enhanced thermal stability, combined with a weight reduction of around 40 percent over their steel/aluminum counterparts. As a result of the reduced unsprung weight, they optimize both comfort and grip, while the reduced rotating masseson the front axle deliver a more direct steering response. The weight savings is approximately 35.3 pounds compared to a conventional steel/aluminum brake system.
