It all started in the U.S. with introduction of the Mercedes-Benz CLK63 AMG Black Series late

last year; a luxury sports coupe that pushed the envelope of the standard version and gave even

more power, performance, and exclusivity to even fewer people. The first car in the Black Series

lineup was an overnight success, with hard-core enthusiasts the world over craving one for their

own garage. In fact, the majority of the 350 cars bound for the U.S. were already spoken for

even before they landed on American soil.

Then, earlier this year came rumors and spy photos of a new Black Series --- this version based

on the venerable Mercedes-Benz SL65 AMG. Motor Trend's very own Todd Lassa was among the first

to confirm the car's existence after it was shown to him and a handful of other journalists at

the 2008 New York auto show this past March, and now we have the full details on the latest bad

-boy Benz. And what details they are.
Starting with the standard SL65 AMG (if you can call anything about that car "standard"),

Mercedes' in-house AMG Performance Studio tweaks the 6.0L V-12 bi-turbo engine for a full 670 hp

-- 58 horses more than the SL65 -- while the torque figure remains identical at an

electronically limited 738 lb-ft for drivability reasons (AMG claims that 885 lb-ft would be

available in derestricted form). To achieve these gains, larger turbochargers were developed

specifically for this application, while a new AMG sports exhaust and optimized airflow tubing

round out the power boost. The result is a heart-pounding 3.9 sec sprint from standstill to 62

mph and an electronically limited top speed just a single mph shy of the magical 200-mph mark.

Such an increase in performance isn't limited to the power increase alone. Weight savings paired

with the horsepower boost provide less mass for the newfound muscle to push around. In fact,

Mercedes claims a reduction of a massive 551 lb from the SL, though the total curb weight still

comes in over the two-ton mark at 4123 lb. To achieve such weight loss, Mercedes constructed

many of the SL65 AMG Black Series' body panels out of lightweight carbon-fiber composite (CFRP),

while also giving the car a fixed roof made from the same material, with an integrated roll bar.

The advantages of the new lightweight roof are two-fold: increased structural rigidity and a

lower center of gravity.

As expected on a car of this type, various aerodynamic aids have been implemented to not only

give the appearance of added performance, but to actually perform the task. A concealed CFRP

rear spoiler will raise at speeds exceeding 75 mph, while a wider front apron incorporates new

carbon splitters to direct airflow in an optimal manner. Out back, a carbon rear diffuser fits

neatly between the outlets of the new sports exhaust system.
