Mercedes-AMG engineers further reinforced the crankshaft assembly to withstand the extreme demands of track driving. This includes modified oil bores, new crankshaft bearings, a new oil pump, and high-strength connecting rod bolts. The entire cooling system for both engine and transmission was also optimized for extreme performance.
Unique to the SLS AMG Black Series, the AMG V8 engine features a specialized mounting system incorporating a gas-filled strut bracing the engine against the body. This effectively minimizes unwanted load shifts during aggressive cornering and track maneuvers. Staying true to AMG’s “one man, one engine” philosophy, each 6.3-liter V8 is hand-built in the AMG factory in Affalterbach, Germany. This handcrafted quality is proudly displayed by the black AMG engine badge, signed by the engine builder – a hallmark of the Black Series models.
The AMG sport exhaust system, constructed for the first time in titanium, is a significant engineering achievement. Featuring performance-enhancing, fan-type exhaust manifolds and distinctive mufflers, it delivers a more ferocious and captivating engine sound. The switch to titanium resulted in a substantial weight reduction; at just under 37.5 pounds, it’s approximately 28.7 pounds lighter than its steel predecessor.
Lightweight Engineering: AMG Lightweight Performance
The 2014 SLS AMG Black Series exemplifies the “AMG Lightweight Performance” strategy. With a curb weight of 3,417 pounds, it’s not only 154 pounds lighter than the standard SLS AMG but also boasts the best power-to-weight ratio of any AMG Black Series vehicle to date. Its 5.49 lb / hp ratio is exceptionally competitive, even among elite super sports cars.
This remarkable weight reduction is achieved through the extensive use of Carbon Fiber Reinforced Plastic (CFRP). Numerous body components, including the hood, rear panel behind the seats, diagonal underbody braces, and the torque tube connecting the engine and transmission, are crafted entirely from CFRP. The carbon-fiber torque tube, for example, weighs just 29.3 pounds, a significant saving compared to the 58.6-pound aluminum counterpart. A CFRP driveshaft, weighing a mere 10.4 pounds, transmits power to the rear axle. CFRP is also utilized for various spaceframe components, and a lithium-ion battery replaces the conventional starter battery, further shedding 17.6 pounds.
Dual-Clutch Transmission and Rear-Axle Differential
The AMG SPEEDSHIFT DCT 7-speed sports transmission is strategically mounted 0.4 inches lower for an even lower center of gravity, enhancing handling dynamics. Gas-filled struts brace the transmission against the body, minimizing load shifts. The dual-clutch transmission offers four drive modes: C, S, S+, and M. “Sport plus” and “Manual” modes deliver even more aggressive performance and faster shift times compared to the standard SLS AMG and SLS AMG GT. The transmission also responds more rapidly to driver inputs.
An exhilarating feature is the automatic rev-matching function during downshifts, amplified by the AMG titanium sports exhaust, creating a truly visceral driving experience. The temporary M mode allows drivers to instantly engage manual mode from C, S, or S+ by simply using the shift paddles, providing on-demand manual control without fully disengaging automatic functions.
Replacing the mechanical variant, a new electronically controlled AMG rear-axle differential lock with a shorter rear axle ratio is integrated into the compact transmission housing. This system provides variable locking effect during acceleration and deceleration, enhancing traction in all conditions. The electronic control system reacts faster than a mechanical system, further improving responsiveness and stability, particularly during high-speed maneuvers and lane changes. The standard three-stage ESP® system and RACE START function are precisely calibrated to work in harmony with the electronic rear-axle differential lock for optimal performance and control.
