Overview

Released in July 2010, the Mercedes-Benz C197 SLS AMG Coupe was a two-seat, high-performance coupe with gullwing doors (the A197 SLS AMG Roadster has been reviewed separately). Manufactured in Sindelfingen, Germany, the C197 SLS AMG was powered by a 6.2-litre V8 petrol engine that was mated to a seven-speed double clutch transmission (Mercedes-Benz’s ‘SPEEDSHIFT’) in a transaxle configuration; the transmission itself featured selectable shift modes and steering wheel gearshift paddles.

M159 engine

The 6.2-litre M159 V8 petrol engine had double overhead camshafts, a forged and balanced crankshaft, four valves per cylinder, dry sump lubrication, a compression ratio of 11.3:1 and a 7200 rpm red line. As such, the SLS AMG Coupe could accelerate from rest to 100 km/h in 3.8 seconds and had a top speed of 317 km/h (electronically limited).

SLS AMG Coupe Black Series

Released in July 2013, the SLS AMG Coupe Black Series was powered by a more powerful 6.2-litre M159 V8 petrol engine. As a result of these engine modifications and mass reduction measures, the SLS AMG Black Series could accelerate from rest to 100 km /h in 3.6 seconds. [su_table responsive=”yes”]

Mercedes-Benz SLS AMG Coupe Black Series

Released in July 2013, mechanical changes for the SLS AMG Coupe Black Series included:

A higher peak engine speed of 8000 rpm;
A revised high-speed valve train with modified camshafts, adapted cam geometry and optimised bucket tappets;
Modified air intake ducting; and,
Optimisation of the crank assembly, including modified oil bores in the crankshafts, a new oil pump and high-strength screwed connections for the connecting rods.

With a kerb mass of 1550 kg (DIN), the Black Series was 70 kg lighter than the standard SLS AMG Coupe due to its:

Titanium exhaust system with fan-type exhaust pipes;
Carbon fibre-reinforced plastic (CFRP) components for the bonnet, rear panel behind the seats, diagonal underbody braces, driveshaft and torque tube between the engine and transmission;
Lithium-ion battery in place of the conventional starter battery;
AMG ten-spoke light-alloy wheels; and,
AMG ceramic high-performance composite brake system (with 402 mm by 39 mm front discs and 360 mm by 32 mm rear discs).

Suspension changes for the Black Series included:

A tauter standard suspension tune with electronically-controlled two-stage damping (‘Sport’ and ‘Sport +’);
Coil-over spring retainers to enable adjustment of wheel loads;
More rigid elastokinematics for greater stability;
Increased track width (by 20 mm and 24 mm for the front and rear, respectively); and,
New wheel carriers on the front axle and a new front stabiliser.

The Black Series was fitted with newly developed Michelin Pilot Sport Cup 2 sports tyres, with 275/35 R19 tyres at the front and 325/30 R20 tyres at the rear for additional grip. Instead of a mechanical differential, the Black Series was fitted with an electronically-controlled AMG rear-axle differential lock with a shorter rear-axle ratio.

Inside, the Black Series was available with Alcantara black and Alcantara black/red colour combinations. The interior also featured:

AMG sports bucket seats;
An AMG Performance steering wheel with Alcantara and a red 12 o’clock marking;
A fine Alcantara strip with contrasting red stitching which extended across the dashboard; and,
AMG sports bucket seats with designo leather, Alcantara and embossed AMG emblems.

Visually, the Black Series could be identified by its flared wheel arches (13 mm at the front and 26 mm at the rear), darkened headlights, black tail-light surrounds, carbon-fibre reinforced plastic front splitter, carbon side sill inserts, carbon fibre rear apron and enlarged air intakes with carbon-fibre flics.
