2014 Mercedes-Benz SLS AMG Black Series

The biggest misconception about the Mercedes-Benz SLS AMG Black Series is that it's simply a higher-performing version of the SLS GT - a closer look, or better yet, a few hot laps on a high-speed racing circuit, reveals that is anything but the case.

Launched in the States in mid-2011, the standard SLS GT is a 583-horsepower, all-aluminum, gull-wing coupe with performance that positions it near the top of the exotic segment. While the AMG team at Mercedes-Benz could have left it alone, their experience with the SLS AMG GT3 race car said there was room for improvement, so they devised the SLS Black Series. The transformation from SLS GT to SLS Black Series is extensive, with no fewer than 17 different significant enhancements.

The engine mapping, crankshaft, connecting rods, valve-train, intake, exhaust and cooling are all modified and the engine's redline bumps up from 7,200 to 8,000 rpm, which pushes output of the hand-built 6.3-liter V8 to 622 horsepower. The power steering receives a new ratio, a coil-over AMG Adaptive Performance suspension is installed along with underbody braces, the track is widened, two-piece carbon-ceramic brakes replace iron rotors at each corner and a lightweight titanium exhaust is fitted beneath. The AMG Speedshift seven-speed dual-clutch gearbox is modified and an electronically controlled AMG rear differential lock ensures the power goes to the pavement. Last on the mechanical upgrades are new lightweight forged wheels (10x19 inches front and 12x20 inches rear) wrapped in special R-compound Michelin Pilot Sport Cup tires.

More visible are the cosmetic upgrades, which basically include new AMG aerodynamic bodywork forward of the A-pillar, carbon-fiber exterior mirrors, a fixed rear wing and other lightweight components. The interior of the cabin is also treated to unique Black Series Designo leather with Alcantara inserts. The short options list includes wheels with matte black paint, Bang & Olufsen BeoSound audio, COMAND multi-media interface and a fitted car cover, to keep the dust at bay while at the track.

The SLS AMG Black Series weighs 3,417 pounds, which is 154 pounds lighter than its GT sibling, but its race car performance carries a $73,500 premium - in terms of engineering and tuning, many would consider it a bargain. To legally explore its performance, I spent the day with the automaker's flagship car at Willow Springs International Raceway in the Southern California Desert.

Track Notes:

• The cockpit of the SLS Black Series is nearly identical to the GT in configuration, but the Alcantara removes some of its luxury polish. The synthetic suede is welcomed, as its adds fingertip grip to the steering wheel and more friction to the seating surfaces. My six-foot two-inch frame fit well, and legroom wasn't an issue, but the top of my racing helmet was brushing ever so slightly on the headliner with the gull-wing door pulled snugly shut. The minor annoyance was forgotten when I pressed the red start/stop button on the center console and the V8 fired to life.
• Adding power, removing weight and raising redline are three easy ways to get my enthusiast pulse racing. The exhaust note on the standard SLS GT is impressive, but the titanium tubes on the Black Series sing a more aggressive song that easily permeated the side glass and drilled through my helmet - long live the wonderful naturally aspirated V8.
• The 40 additional horses improve acceleration slightly, but more important are the mapping changes to the gearbox. I ran the Black Series in S+ (Sport Plus) driving mode, which delivered crisp gear shifts and throttle blips coming into the corners. The upgraded programming is aggressive, but I never questioned its logic and found the coupe ran best when the computers were tasked with shifting.
• I'm used to running Big Willow in cars that need lots of throttle around Turn 2 and can go down the back straight flat-out. The 622-horsepower SLS had me at partial throttle around the constant radius turn, and lifting down the back before entering dicey Turn 8. With a clean exit of Turn 9, I was able to hit a blistering 140 miles per hour down the front straight.
• Willow Springs is as old as your grandparents, with a track bed and surface that is really starting to show its age. While most of the pavement is smooth, some of the fastest corners are marked with dips and undulations that try their best to unsettle a chassis. Running the active dampers in their firmest setting was uncomfortable and unnerving, as some of the tires felt like they were losing contact with the road, so I backed the firmness off a stage to allow the wheels to follow the surface. Once I was running the proper setting, the grip from the wide and sticky Michelin tires (325/30ZR20 in the rear!) was extraordinary. Understeer has vanished, but oversteer remains just a stab of the throttle away.
• Tasked with less mass to stop and with tenacious carbon-ceramic friction surfaces, the brakes were a non-issue. Pedal feel was good, even though they didn't have race car firmness, and I rarely found the need to ask for ABS assistance even when the chassis was bounding over a bump on the surface. Some of the credit goes to those gummy tires, which refused to let go.
• A day at the racing circuit taught me that the SLS Black Series is a hardened track variant, which is best thought of as a tuned-down race car rather than a gussied-up street vehicle. In terms of performance, nothing has been left untouched by the AMG engineers and its performance at Willow Springs was nothing short of spectacular. This type of tuning is absolutely overkill for public roads, but I can't refrain from commending the brilliant engineers who were tasked with creating this uncompromising devil. It is one of my favorites.

Awesome! Wow they really cranked that NA V-8 up! 622hp and 8k!!

I like the extra styling bits on this. They manage to make the rear spoiler not look overdone, as it can on, say, the LFA. At the same time, I believe this is by far the lightest-weight road-going SLS and it's still 3417 pounds?

3417 is very light for today's standard!

This black motor is dramatically revised compare to the standard SLS's M159 motor, that is why the gain is so huge. Is not just a tune and exhaust..........

I read it, but I forgot the details now.

Outstanding vehicle. That 6.2L V8 is a gem. It will be missed

SteVTEC

Definitely not when you're talking about bumping the rev limit from a rather pedestrian 7200 to a pretty freakin serious 8000!

i have to be honest i am still warming up to the sls styling, but i think it's a pretty serious car (unlike the previous slr)

Also the SLS is very light compared to the SLR

I was lucky enough to be able to spend the whole day at Laguna Seca last weekend driving the SLS GT (not black series) on the track and it's a blast to drive! It's loud enough that the track asked us to only go 1/2 throttle in the straight away between turns 6 and 7 to keep from disturbing the neighbors too much. I'd love to have a chance at the black series...

lmao that's awesome! Like I said the 6.2L in all of its iterations is simply phenomenal. From it's 451hp C63 AMG to this 622hp SLS AMG Black Series
