Just yesterday, Mercedes-Benz released a teaser on its Facebook page showing what we could only guess was the SLS AMG Black Series, and this morning our suspicions proved true as the automaker removed the tight-fitting cover. Preparing for the car's official debut at the 2012 LA Auto Show, the latest addition to the Mercedes-Benz Black Series is by far the most impressive with extensive measures taken to improve performance and reduce weight.
Underneath the SLS' long hood, AMG has reworked the engine squeezing an extra 39 horsepower from the 6.2-liter V8 raising the output to 622 hp. And even though overall torque has dropped by 11 pound-feet, acceleration from zero to 60 miles per hour is quicker at 3.5 seconds. Top speed is 196 mph. The handling of the car has also been improved on all levels, including upgraded ceramic brakes with two-piece rotors (measuring 15.8-inches in the front and 14.2-inches at the rear wheels), adjustable coil over suspension, electronically controlled rear differential and a track that has been widened by almost an inch. For added rigidity, many of the body braces in the aluminum space frame have been replaced with carbon fiber reinforced plastic (CFRP) helping to shed precious pounds.
At 3,417 pounds, the SLS AMG Black Series has dropped a total of 154 pounds compared to the SLS AMG GT. Some of the numbers are actually pretty significant, such as the 35.3 pounds saved with the ceramic brakes, 29.3 pounds cut thanks to using a CFRP engine-to-transmission torque tube rather than aluminum and 28.7 pounds from the titanium exhaust system. Showing AMG's determination to shed pounds, even the car's conventional battery has been replaced with a lithium-ion battery which is good for another 17.6 pounds of curb weight savings – possibly the first such application of a lithium-ion battery outside of a hybrid or electric vehicle.
The 2014 SLS AMG Gullwing Black Series goes on sale next summer, but Mercedes has yet to announce pricing or production numbers.
