|Mercedes finally revealed the much awaited SLS AMG Black Series. The Mercedes SLS Black is inspired by the GT3 racing version of the Gullwing, it’s lighter than the standard version, and it promises improved driving dynamics. The Mercedes SLS Black Series weighs 3,417 pounds and it has a power-to-weight ratio of 5.49 lb/hp. The power comes from the well-known AMG 6.3-liter V8 engine, which in this application develops 622 hp at 7,400 rpm and 468 lb-ft of torque at 5,500 rpm. Merc’s official specifications for the SLS AMG Black say it can accelerate from zero to 60 mph in just 3.5 seconds and that it can reach a top speed of 196 mph. The red line comes at 8,000 rpm.|
The SLS Black sends its power to the rear wheels via the AMG SPEEDSHIFT DCT 7-speed transmission, and an electronically-controlled rear-axle differential. So much power requires improved control capabilities. For this purpose, Mercedes equips the SLS AMG Black with a coil-over Adaptive Performance Suspension system, high-performance ceramic two-piece brake system, lightweight wheels and sport tires.
To get the extra power out of the SLS AMG’s engine, Mercedes revised the high-speed valve train with modified camshafts, and adapted the cam geometry. They also optimized the bucket tappets that now feature a special coating that’s used for racing cars. They also optimized the car’s intake system and re-mapped its ECU
