The Mercedes Black Series models are the most extreme cars the company produces, and this is its most hardcore road car ever.
The SLS AMG Coupe Black Series - which has been unveiled at the LA Motor Show - features the same 6.3-litre V8 as the standard car, but power is up by 59bhp to 622bhp, while the rev limit has been increased from 7,200rpm to 8,000rpm.
Mercedes has also shed 70kg from the SLS’s kerbweight. A new carbon fibre torque tube is 13.3kg lighter than the aluminium unit in the regular car, while a lithium-ion starter battery saves 8kg and the bonnet, bucket seats and various chassis parts are now made of carbon fibre-reinforced plastic.
The result of all these changes is a higher power-to-weight ratio than on any previous AMG Black Series car, and the SLS covers 0-62mph in 3.6 seconds. Top speed is 1mph down on the regular car, at 196mph, as tweaks to the aerodynamics have increased drag.
These include a large, fixed, optional carbon fibre wing at the rear, although a smaller spoiler that rises at 75mph is standard. There are aggressive diffusers front and rear, plus a muscular new bodykit.
Further marking out the new model are a subtle Black Series badge on the rear and a new set of exhausts. The exhaust system is now made of titanium, and emits a tuned note that Mercedes claims is “even more striking” than the regular SLS’s bassy Spitfire growl.
Underpinning the ultimate SLS are new mechanicals. The track is wider – by 20mm at the front axle and 24mm at the rear – plus the suspension has been tweaked for maximum agility. There are carbon ceramic brakes, while an updated seven-speed MCT semi-auto box sits 10mm lower to improve the centre of gravity.
The cabin is recognisable from the standard SLS, but gets 15kg lighter bucket seats. Drivers will find there’s no COMAND control system – saving 6kg – although it can be fitted for free. There’s lots of carbon fibre, plus red seatbelts and red contrast stitching.
