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.
The Safety Car version of the German firm’s coupe uses the same 6.3-litre V8 engine with 510hp (517PS) and 620Nm (457 lb-ft) found in the production car, which allows for a 0-100km/h (62mph) sprint in 4.2 seconds and a limited top speed of 300km/h (186mph).
The only mechanical upgrade over the production C63 AMG Coupé Black Series concerns the modified exhaust system.
Mercedes has fitted the car with the optional AMG Track package that adds active rear axle gear cooling and 19-inch alloys shod in Dunlop Sport Maxx Race sports tires in size 255/35 R 19 at the front and 285/30 R 19 at the rear, an AMG Aerodynamics kit that includes a carbon-fibre front splitter, plus a fixed carbon-fibre rear aerofoil with adjustable blade, and the AMG Exterior Carbon-Fibre package.
On the outside, you’ll also find a light bar with a stroboscope-type flashing LED fixture on the roof.
As for the interior, the Safety Car features a pair of AMG sports bucket seats with four-point seat belts, a two-way radio system and TV monitor mounted on the center console and the buttons that control the exterior safety lights.
