Tesla S vs RENNtech tune only E63

Wednesday, February 6th, 2013


Published: Feb 05, 2013

The same Tesla Model S that successfully beat a Dodge Viper in a quarter-mile showdown is back this week going up against a Mercedes E63 AMG.

Instant torque is a wonderful thing yet EVs in general are not popular amongst gearheads and probably never will be. That doesn’t distract from the fact the new Tesla Model S is quite the performance machine. For last week’s installment of Drag Race Tuesdays we saw the Model S successfully beat the Dodge Viper SRT10 on a quarter mile strip. As a result, it set a new record as the world’s fastest production EV.
Now that same Model S is back, this time going up against a RENNtech-tuned Mercedes-Benz E63 AMG. So can the mighty EV repeat its incredible performance from last week? Check out this week’s quarter-mile showdown to find out.

Matt Farah visits RENNtech and drives our CLS 63

Wednesday, September 5th, 2012


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:
