With all the tuners we feature there is the question of “How did you get started?” Why are they here, and what gives them the credibility to convert money into speed. With the company RENNtech, that man is Hartmut Feyhl. Cred? Yes. He started working at the AMG facility when he was 17. He worked there for 12 years, then served as the North American technical director, all before he opened RENNtech. The famous AMG Hammer? The one Chris Harris just drove (For the CH fanboys, this must have been like finding the first Playboy Pamela Anderson did, complete with bush.)? Those were built by Hartmut. Back then it was almost impossible to import a German car (one that wasn’t approved for U.S.). So AMG’s solution was convert some W124s that were already in America. Really, he was there for AMGs genesis. So, bringing your car to him is like bringing it back to AMG itself and saying, “Please, Sir, may I have some more?” More horsepower porridge, coming right up.
That’s what they’re doing with this CLS 63 AMG, a car that won our hearts in stock form (a memory now completely erased and over-shadowed by this superior rolling-burnout factory), RENNtech has modified the turbos, transmission and diffs so it produces over 700HP. They were still developing the kit, so it will eventually have almost 800HP, and (on the right tires) run 9s. 9 second 1/4 mile with massage seats, leather, and NAV, in a car as long as the street you live on. It’s simply ridiculous. watch the episode:

We recently attended the StreetCarDrags.com event held at Palm Beach International Raceway on May 6, 2012. This is the 3rd StreetCarDragsevent we attended, and, as before, many amazing cars showed up to race including multiple Corvette ZR1s, GTRs, Vipers, Evos, Camaros and some Benzes. Trophies were awarded for the Fastest American Car, Fastest Japanese Car, Fastest European Car, Best 60 foot time and Best Reaction Time.
The Benz that brought home the trophy for the Fastest European car was RENNtech’s 2012 CLS63 with a stout 10.79 @ 130.77 mph. RENNtech brought out a few of its project cars and gladly accepted our request to strap some of our test equipment into its record setting 2012 CLS63 to get some performance numbers.
May in South Florida is generally warm and humid, and May 6th was no exception. At the time of our testing, the temperatures were in the mid to high 80s with a density altitude of over 2000 feet. Despite the less than desirable conditions, the acceleration numbers were staggering from RENNtech’s warmed over V8 BiTurbo CLS63 …. as you can see from the data below:
0 to 60 mph 3.0 seconds ( 4.2 seconds)
0 to 100 mph 6.5 seconds ( 9.2 seconds)
60 to 130 mph 7.6 seconds (11.4 seconds)
The RENNtech CLS63 has the following mods: RENNtech modified ECU, larger heat exchanger, high efficiency intercooler pump, 100% locking differential, high flow downpipes with 200 cell cats, drag radials and front skinnies. The RENNtech CLS is still equipped with its stock turbos and stock airboxes (for now..), and the car retains all of its stock interior as no weight was taken out of the vehicle.
We also got a chance to log some miles on this car after the event and can say, without hesitation, that the rush of power from the RENNtech mods is eye ball flattening at every RPM. However, the RENNtech CLS63 is a docile as a stock CLS63 for everyday use.
An otherwise bone stock, tune only 2012 Mercedes E 63 ran an incredible 11.15 @ 126.7 mph quarter mile this past weekend at Palm Beach International Raceway. The E63 dynoyed an impressive 578.33 horsepower and 621.93 ft/lbs of torque at the wheels (680 horsepower and 732 ft-lbs of torque at the crank) with the RENNtech tune installed. That is a 100 horsepower gain over stock!
The run was made with the stock exhaust, stock wheels and OEM street tires in 80 degree temps with damp track conditions. Needless to say, we expect quite a bit more out of the new biturbo E63 and will certainly be breaking into the 10′s very shortly.
Stay tuned as we continue to push the performance of Mercedes latest powerhouse.

The team at RENNtech was delighted to be involved with the Doug Mansfield Foundation and the efforts of both his charity and on the behalf of Barrett Jackson in order to provide proceeds from the sale of our 2004 SL 600 Chrome car to be donated to such a noble cause. The vehicle was sold at no reserve and brought in $155,000 USD with all proceeds from the sale of this vehicle being donated to the Doug Mansfield Foundation Trust, a Sarasota based charity that provides seeing eye dogs for children and blind veterans.
The lucky bidder of this vehicle not only be helped to support the needs of blind veterans, but become the new owner of a piece of history.
The 2004 RENNtech SL 600 Chrome car was developed in part with Nitto Tire for the 2004 SEMA Show. It features a heavily modified RENNtech V12 engine, making over 650 HP and 800 Lb/ft. The entire exterior of the car was finished with a one off, first of its kind chrome paint utilizing actual silver which took several months to complete. The result was a mirror like finish which gave the appearance that the entire vehicle was carved from a single piece of metal.
RENNtech congratulates the new owner of this exceptional vehicle and the efforts of everyone involved with this charitable project.
