HP Wars not over: RENNTech announces 695 HP package for Mercedes AMG models

While Mercedes-Benz and AMG may be claiming that future high-performance models bearing the three-pointed star will not place such a heavy emphasis on high horsepower, that doesn't mean aftermarket tuner RENNTech is giving up the fight. The German tuner announced today a new Stage 3 package for any Mercedes AMG model powered by the company's twin-turbo 6.0L V12, a.k.a. the AMG 65-series of models. These include the S65, CL65 (shown) and the SL65 AMG.

Normally producing an already unreasonable 604 horsepower, the 65-Series TT V12 is improved with "next-generation ECU software" to get 695 HP and 890 lb-ft of torque. In addition to an extra 91 horsepower, RENNTech also claims its software tuning improves gas mileage and emissions. Of course, any bump in power requires a likewise improvement to heat management and airflow, so RENNTech also adds a bigger intercooler pump and secondary heat exchanger, as well as a pair of carbon fiber air filter boxes and new stainless steel sport mufflers. Be warned: the cost for all this will add another $18,990 plus labor to the cost of your AMG 65-Series.

Looks stunning... Very nice and elegant tuning...

yep thats some great tuning

Looks ok, still hate the wheels though.

M

^^I actually quite like those wheels, at least in the pic shown above.

Terrible rims.

The wheels aren't that great but you can't blame them. After all, those look like genuine three piece rims.

I'm not a fan of these aftermarket tuners. IMO they ruin the car more visually than enhancing it. To each his own I guess.
