2009 Mercedes-Benz SL65 AMG

Recommended Posts

Starting with the standard SL65 AMG , 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.

Brakes and suspension have also been tweaked

for Black Series duty, with larger discs at all four corners,

supplemented by six-pot calipers up front and four-pot items in the

rear, covered by 19- and 20-in. black AMG wheels at each respective

end. Rubber comes from Dunlop (AMG's DTM partner) in the form of a set

of Sport Maxx GT tires. A new adjustable coil-spring suspension is

fully adjustable for track duty, and the track has even been widened by

3.8 in. in the front and 3.3 in. in the rear. Meanwhile, weight has

been reduced in the new aluminum wheel carriers and the spring links,

camber struts, and pull/push rods at both axles are all of new design.

The

standard AMG Speedshift Plus five-speed automatic transmission is

retained from the standard SL65 AMG, likely deemed suitable as a result

of the nonexistent torque increase. The transmission features four

modes with varying degrees of comfort and performance and an automatic

rev-matching feature on downshifts. Three-mode ESP is fitted in

conjunction with a limited-slip differential with 40-percent locking

capability to keep power delivery optimized and the car pointed in the

right direction.
