RENNtech Reveals 695 HP Monster Mercedes Tuning Package

Not wanting to get left behind in a world of 500 horsepower Euro-bruisers, RENNtech announced today its new "stage 3" kit designed to squeeze an impressive 695 horsepower and 895 lb-ft of torque out of the twin-turbo AMG V12. The kit uses a revised ECU, revised cooling system and other goodies to get as much usable power out of the V12 as can be reasonably gotten. The addition for 65-series AMG's is $18,900 plus installation and is available on the S65, CL65 (pictured) and SL65 AMG. Full press release below the jump.

The last few years have seen a flood of 500 horsepower sedans almost
pouring out of Germany from BMW, Audi, and Mercedes-Benz. Earlier
this month, however, representatives from Mercedes and AMG announced
that the "horsepower wars" were over, saying that outright power would
no longer be the "main focus" for future sports sedans.

Apparently, no-one sent that "war over" memo to RENNTECH.

This morning, RENNTECH announced a new "stage 3" tune for the 2008 65
series AMG models, which makes use of what RENNTECH calls
"next-generation ECU software" to get 695 hp and 890 lb-ft of torque
from the AMG's twin-turbo V12.

"Power will always be important to many customers, especially torque."
explains Hartmut Feyhl, RENNTECH's president and ex technical director
of AMG North America. "Our cars have always been able to make
considerable torque, and have been praised in magazines for their
drivability. Still, we are constantly trying to improve our product."

Commitment to constant improvement is one reason RENNTECH has become
known as one of the world's premier tuning firms, and America's
foremost authority on Mercedes-Benz. RENNTECH believes their new
software will further cement that knowledge in the public mind. "We
now have two in-house engineers that are doing software full-time, and
others that work with the software on a part-time or contract basis.
We are always looking for improvements. The latest software takes
advantage of the increased power of the new engine computers, and
offers a number of small improvements that add up to a big 'overall'
improvement," Feyhl explains. "It really is that 'next-generation'
sort of product that is much more advanced than what we were capable
of offering before. Compared to earlier versions, our new software
gives customers more power and better drivability in a way that is
more reliable, smoother power curve, and even improves emissions and
gas mileage."

In addition to the software upgrades, RENNTECH adds a larger
intercooler pump and secondary heat exchanger, as well as a pair of
carbon fiber airboxes to improve the flow of cool air into the big
AMG's V12. The intercooler system upgrades reduce air intake
temperatures by more than 20 degrees, delivering more consistent power
compared to stock and allowing RENNTECH to more safely increase boost
throughout the rpm range.

RENNTECH's stainless steel sport mufflers (also part of the new
package) produce a deep, distinctive growl that is suitably aggressive
for a high-end luxury car. Feyhl suggests that his mufflers "let the
car sound the way it is supposed to sound."

With almost 900 lb-ft of torque available from the engine, RENNTECH's
upgrades deliver a real, noticeable improvement in terms power and
acceleration compared to the already impressive performance of the
stock 65 series AMG cars. MSRP for RENNTECH's new performance "PKG3"
for 65 series AMG is $18,990 (plus installation). PKG365 is available
for S65, CL65, and SL65 AMG. Contact RENNTECH for more.
