The most hardcore iteration of the SLS AMG with the Black Series moniker is said to borrow bits and pieces from the race-spec GT3 model including parts for the heavily tweaked 6.2-liter V8 engine that produces 622hp (631PS) at 7,400rpm, 39hp more than the 2013 SLS AMG (583hp / 591PS).
On the other hand, the Black Series’ V8 delivers 11 lb-ft less torque at 468lb ft arriving at 5,500rpm. It is said to complete the 0-100km/h (62mph) in 3.6 seconds and top out at 315km/h (196mph), making it 0.1 seconds faster in the sprint but 1mph or 2km/h slower in terms of maximum speed.
Other noteworthy changes include a revamped chassis with wider tracks, reprogrammed electronics, lowered suspension and carbon ceramic breaks, plus new 19-inch front and 20-inch rear wheels, and an assortment of aero upgrades.
Brabu’s performance offerings also include a special sport exhaust system with a butterfly valve for the CLS 63 that allows the driver to switch between a discrete “Coming Home” mode and a “Sport” mode for a throatier exhaust note.
For all other models, the German tuner offers stainless-steel quad sport exhaust systems, a clutch-type limited-slip differential with a locking rate of 40 percent, and sport springs plus an electronic module that lowers the ride height of cars equipped with the semi-active AIRMATIC air suspension system by about 35mm (1.37 inches).
The regular models can be fitted with an aero package comprising a front spoiler, front fascia attachments with integrated LED daytime running lights, sport fenders and side skirts with integrated entrance lights.
For the AMG sport package-equipped versions, Brabus has developed a front spoiler lip that attaches to the underside of the front fascia, while for the CLS 63 AMG, there’s a front apron and fender attachments with backlit ‘BRABUS’ logo.
Alloy wheel options includes rims in sizes ranging from 8.5Jx17 to 10.5Jx20, the latter fitted with tires 255/30 ZR 20 in front and 295/25 ZR 20 at the rear axle.
Finally, there’s a variety of interior goodies including bespoke upholsteries, scuff plates with backlit ‘BRABUS’ logo, different speedometers, and aluminum trims.
For the paltry sum of €30,000 or about $38,900 / GBP24,100, German tuning brand Fostla can take your stock, previous generation Mercedes-Benz SL55 AMG from the R230 series, and rework it inside and out to give it a more unique look and at the same time, boost its performance credentials.

The battery-powered SLS AMG is said to accelerate from zero to 100km/h (62mph) in just 3.9 seconds with its top speed electronically governed at 250km/h (155mph).
