The performance version of the SL 65 AMG was unveiled in Monterey in 2008.
The turbochargers are 12% larger, and the optimised wastegate ducts permit increased air throughout.
The intake air ducting and exhaust system are modified to improve response and reduce the exhaust gas backpressure.
The Black Series is 250 kilograms (551 lb) lighter than regular SL 65 AMG by the use of light carbon fibre composite (CFRP) parts and the omission of the SL's normal foldable hardtop roof, replacing it with a fixed roof.
Not only did this save weight, it also made room available for the retractable rear spoiler.
It also has an def limited top speed of about 200 mph-(322 km/h) and can go from 0-62 mph-(0–100 km/h) in 3.8 seconds.

The AMG Speedshift Plus five-speed automatic transmission include "C", "S", "M1" and "M2" which has gearshift times 25 percent quicker than the "M1" mode.
The Black Series front axle track width is 97 millimetres wider and the rear axle track width 85 millimetres wider over regular model.
Other changes include retractable rear spoiler and the rear apron with diffuser fins, 265/35R19 front tyres with 19x9.5 inch AMG light-alloy wheels and AMG 20x11.5-inch light-alloy wheels with 325/30R20 tyres (Dunlop Sport Maxx GT tyres), 6-piston front calipers with 390x36mm discs and 4-piston calipers with 360x26mm discs.
