Just when you thought you'd seen the last of RENNTECH's work on the Mercedes SLR McLaren, the company is back tuning the supercar yet again, unveiling what they call the "777 Concept."  The model is being introduced to celebrate the 20th anniversary of RENNTECH, and as such, it shows fantastically the magic RENNTECH-tuned models are capable of.

Seven hundred seventy-seven horsepower; a top speed of more than 210 miles-per-hour; extensive lightweight aerodynamic body components; and a limited production of just 20 units – this is just a sampling of what customers of the RENNTECH 777 concept have to look forward to.

According to Hartmut Feyhl, president of RENNTECH:  " Last year, it was a coincidence that we were releasing a
new, 695 hp performance package for the 65 series AMG
cars at around the same time. We sent out a press
release that said 'HP War Not Over'.  This year it is the same timing again, and we have something much more extreme to
announce for our 20th Anniversary." He adds:  "This 777 concept is really an all-new car that makes use of the advanced carbon fiber chassis of the SLR McLaren.  It can be described as a street-legal track car, or something closer to what the enthusiasts were hoping for from the SLR, originally - which is more a successor to the McLaren F1."

If you're interested, the first of the RENNTECH 777 concepts is being built now, with pricing available on request. For a small preview of what to expect, however, keep scrolling for a pair of photos highlighting the model (click either to enlarge), followed by the full press release detailing its various attributes.

Enjoy ladies and gentlemen.

OFFICIAL PRESS RELEASE


RENNTECH 777 20th Anniversary, or: Horsepower Wars really Really REALLY Not Over

Lake Park, FL – Earlier this week, AMG boss Volker Mornhinweg
announced that â the horsepower war is over." If this
sounds familiar, it's because AMG issued a similar press
release LAST JANUARY.

"Last year, it was a coincidence that we were releasing a
new, 695 hp performance package for the 65 series AMG
cars at around the same time. We sent out a press
release that said 'HP War Not Over'," recalls Hartmut
Feyhl, president of RENNTECH and four-star General of
the horsepower wars. "This year it is the same timing
again, and we have something much more extreme to
announce for our 20th Anniversary."

Feyhl founded RENNTECH in 1989, and the company
has since established itself as one of the world's premier
tuning firms and the foremost authority on Mercedes-Benz
performance tuning. 2009 marks the company's 20th year
in business, and the company intends to celebrate by
releasing a small number of extreme, limited edition
performance vehicles, beginning with the 777 hp,
RENNTECH 777 shown here.

"This 777 concept is really an all-new car that makes use
of the advanced carbon fiber chassis of the SLR McLaren.
It can be described as a street-legal track car, or
something closer to what the enthusiasts were hoping for
from the SLR, originally - which is more a successor to the
McLaren F1."

RENNTECH heavily revised the SLR McLaren bodywork
and aero package using some of the same technology the
company used to develop the the GLK Hybrid Rally Racer
for Mercedes-Benz, including advanced CFD software to
develop the aerodynamics for improved downforce. Even
with the big wing, splitters, and skirts, a top speed in
excess of 210 mph is well within reach for the 777.

The 777 is much more than lightweight bodywork,
however. The 5.5 L supercharged "Kompressor" v8
engine is heavily revised, with internal and external
performance upgrades and a significantly upgraded
cooling system.

Getting that power to the ground is the job of a fully
redesigned suspension and driveline, with a heavily
reinforced transmission sending power to RENNTECH's
revolutionary new limited-slip differential. Built for
RENNTECH by Japanese supplier OS Giken, the
recently-released differential allows for 100% locking
between the drive wheels for unsurpassed mid-corner
traction. Aggressive Nitto NT-05 ultra-high performance
tires wrapped around extremely lightweight, 1 pc. center-
locking wheels round out the street -legal handling
package.

"The 777 will be a very special car," explains Hartmut.
"The first example is being built now, and will be ready
this Spring. We intend to build a few different extreme
vehicles like this for our 20th anniversary, with each one
being strictly limited to 20 units. They are all very exciting
projects, and we will be announcing them throughout the
year, as they approach completion."
