The new Black Series from Mercedes-Benz is an even more driver-focused variant of the V8-powered SLK 55 AMG Roadster.

Output from the 5.5-litre AMG engine is boosted from 360 hp to 400 hp and 45 kg has been shaved off the kerbweight through the use of lightweight components including a new fixed hard top. As a result, the 0 to 62 mph dash drops from 4.9 to 4.5 seconds, while 125 mph is, where permitted, clocked up in just 15.5 seconds – a full two seconds quicker. Top speed is no longer restricted to 155 mph, and the car can reach 173 mph!

The nose features new, more muscular front wings made from ultra-light carbon fibre-reinforced plastic (CRP) and a restyled AMG front skirt with carbon fibre inlays. Large air intakes and side air outlets ensure a sufficient flow of air to the enlarged engine oil cooler and new transmission and steering oil coolers.

The chassis has been modified to match the increased performance capability of this special series SLK 55 AMG. Racetrack-optimised, AMG height-adjustable torsion suspension, including adjustable dampers permits more impressive cornering ability. 19 inch ultra-light AMG forged alloy wheels replace the 18 inch items of the standard car. Greater body rigidity is provided by a brace across the engine bay, and for those looking for even sportier handling, there’s also an optional limited slip differential.

Optimised for track use, the hydraulic vario roof mechanism of the standard car has been removed leaving a fixed hardtop with a central section in black carbon-fibre. A pity then that drivers won’t be able to feel the wind but at these speeds they’ll be glad of the shelter!

The SLK 55 AMG Black Series is priced at 92,500 euros and is available by special order from Mercedes-Benz Retailers.
