Renntech Tunes The Mercedes-Benz CLK63 AMG Black Series
|
[06/17/2008] For most, the consummate power and impeccable handling of the Mercedes-Benz CLK63 AMG Black Series is more than sufficient. Directly from the factory, it boasts output of 373 kW/507 hp and 630 Newton meters of torque, enough to propel the model from 0-62mph in just 4.3 seconds and reach an electronically-limited top speed of 186 mph.

For most, the consummate power and impeccable handling of the Mercedes-Benz CLK63 AMG Black Series is more than sufficient. Directly from the factory, it boasts output of 373 kW/507 hp and 630 Newton meters of torque, enough to propel the model from 0-62mph in just 4.3 seconds and reach an electronically-limited top speed of 186 mph. Then there's the high-performance brake system, the track-optimized adjustable threaded suspension, the specially-developed cooling systems... well, you get the idea. But for those of you whose contentment knows no bounds, Renntech has introduced a tuning package for the formidable model - one that aims to extract a bit more power and drivability from an already supremely capable vehicle.
In total, Renntech has managed to increase output of the CLK63 AMG Black Series to 550 horsepower, and even more noteworthy, they've also managed to deliver an additional 45-60 lb-ft of torque between 2400 and 5000 rpm. According to Hartmut Feyhl, founder of Renntech: "Real-world performance is all about torque, not so much about a peak horsepower number at very high rpm. It can be very easy to build high rpm
horsepower, but to get instant throttle response and mid-
range acceleration it is more difficult, and this is where
customers really want to feel that improvement."
Next, to better the CLK63 Black Series' handling, Renntech lowered the car 3/4" and added carbon-fiber strut braces and fully-adjustable camber bushings at all four corners. To improve aerodynamic efficiency, an adjustable carbon fiber rear wing and a front splitter/rear diffuser combination were introduced, while completing the package are high performance brake pads and stainless-steel braided lines (ensuring an ample amount of stopping power, should the need arise).
Although Renntech's tuning package isn't necessary to experience an immense amount of exhilaration while piloting your CLK63 AMG Black Series, it is an uncomplicated way to experience more of what your illustrious model already provides.

OFFICIAL PRESS RELEASE
RENNTECH for the Mercedes-Benz CLK63 AMG Black Series
Mercedes-Benz made a big splash with the introduction of
its CLK63 AMG Black Series coupe last year. The
aggressive "F1 safety-car" look gave the 500 hp CLK
Black a visual edge that the CLK55 AMG lacked, and the
Black Series' suspension and brakes were in a decidedly
different league compared to other Mercedes.
Impressive spec sheet notwithstanding, some customers
will still believe that 500 hp is not enough, and for those
select few who find the CLK a bit tame, there is always
RENNTECH.
Established in 1989 by Hartmut Feyhl (ex technical
director: AMG North America), RENNTECH quickly made
a name for itself with high-powered magazine tuner-
shootout cars that were reliable enough to actually be
driven from RENNTECH's home in South Florida
thousands of miles to events in Texas and Michigan. For
the CLK Black, Feyhl told his crew to develop the same
kind of "real-world" performance upgrades that made his
cars so famous to begin with.
"Real-world performance is all about torque, not so much
about a peak horsepower number at very high rpm,"
explains Feyhl. "It can be very easy to build high rpm
horsepower, but to get instant throttle response and mid-
range acceleration it is more difficult, and this is where
customers really want to feel that improvement." To build
that improvement, RENNTECH adds long-tube headers
and a motorsports style exhaust to the already-potent 6.2
liter engine, tying it all together with RENNTECH's own
ECU software, sharpening throttle response and boosting
550 peak hp. The real story, however, is drivability - and
this is where the RENNTECH tuning package shines,
delivering an additional 45-60 lb-ft of torque between
2400 and 5000 rpm.
To "sharpen" the car even further, RENNTECH fine-tuned
the CLK63 Black Series' suspension, lowering the car 3/4"
and adding carbon-fiber strut braces front and rear. To
enhance mechanical grip in fast corners, RENNTECH
also added fully-adjustable camber bushings at all four
corners. Aerodynamic stability is also greatly enhanced
with an adjustable carbon-fiber rear wing element and a
front splitter/rear diffuser combination to manage
underbody airflow, building usable downforce and
(adjustable) aerodynamic balance at speed, while
directing cooling air to the Black Series' huge AMG brake
rotors - themselves enhanced with high-performance
pads and stainless-steel braided lines. The result is a
hard-core CLK63 from RENNTECH that does the
unthinkable: it makes the standard CLK63 seem a bit soft.
