Compared to the already potent SLS AMG GT, the Black Series gains an additional 39 horsepower through a series of significant enhancements. These include an increase in maximum engine speed from 7,200 to 8,000 rpm, a completely revised high-speed valve train with modified camshafts and optimized bucket cam followers featuring a special coating derived from racing applications. The intake air ducting has been modified for de-throttling and optimized for the higher engine speeds, along with adjustments to the engine mapping and an increase in intake pressure.
Mercedes-AMG engineers further reinforced the crankshaft assembly for unwavering stability under demanding race track conditions. This involved modifying oil bores in the crankshaft, incorporating new crankshaft bearings and oil pump, and utilizing high-strength connecting rod bolts. The entire cooling system for both engine and transmission has been meticulously optimized to ensure peak performance even under extreme stress. Adding to the engine’s robustness, a specialized gas-filled strut mounting system braces the V8 against the body, effectively minimizing unwanted load shifts during high-speed cornering and dynamic driving maneuvers, crucial for optimal car detailing and performance.
The AMG V8 engine in the SLS AMG Black Series is hand-built in Affalterbach, Germany, following AMG’s “one man, one engine” philosophy. This dedication to craftsmanship is highlighted by the black AMG engine badge, signed by the engine builder, a signature element of the prestigious Black Series models. The sound emanating from this engine is as thrilling as its performance, providing an aural experience that matches the visual drama of the Mercedes-Benz SLS AMG Black Series.

Precision Transmission and Enhanced Drivetrain
Power from the V8 engine is channeled through the AMG SPEEDSHIFT DCT 7-speed sports transmission, repositioned 0.4 inches lower for an even lower center of gravity, further enhancing handling. The transmission is braced against the body with gas-filled struts to eliminate undesirable load shifts. Offering four drive modes – C, S, S+, and M – the transmission provides a spectrum of driving experiences, with “Sport plus” and “Manual” modes delivering even more aggressive performance compared to the standard SLS AMG and SLS AMG GT. Shift speeds are increased, and the transmission responds more rapidly to driver inputs.
A particularly exciting feature is the automatic rev-matching function during downshifts. Enhanced and amplified by the AMG titanium sports exhaust system, the throttle blips during gear changes are more pronounced and visceral, adding to the immersive driving experience. The inclusion of a temporary M mode allows drivers to momentarily engage manual mode from C, S, or S+ modes by simply using a shift paddle. This provides on-demand manual control without fully disengaging the automatic driving programs, allowing drivers to concentrate fully on the car’s performance.
Complementing the advanced transmission is a new electronically controlled AMG rear-axle differential lock, replacing the mechanical variant and featuring a shorter rear axle ratio. Integrated into the transmission housing, this system provides variable locking effects during both acceleration and deceleration. The electronic control offers faster response, ensuring exceptional traction in all driving conditions. Furthermore, the electronic differential lock enhances safety by reducing yaw around the vehicle’s vertical axis, providing increased stability during quick maneuvers such as slaloms or high-speed lane changes. The standard three-stage ESP® system and RACE START function are finely tuned to work in perfect harmony with the electronic AMG rear-axle differential lock, optimizing both performance and control.
