renntech for sprinter






Designed and built by Mercedes-Benz, the Dodge Sprinter is powered by a 3.0 liter turbodiesel engine that produces 154 hp and 280 lb-ft of torque between 1200 and 2400 rpm. Not bad (especially considering that this full-size cargo van delivers almost 21 MPG), but nothing to write home about ... and that's where Hartmut Feyhl comes in.

As owner and chief engineer of South-Florida tuning firm RENNTECH (and ex-technical director at AMG North America), Feyhl has built some of the fastest, most exciting Mercedes' of the last 20 years. In that time, Feyhl and company have learned quite a bit about making internal-combustion engines more powerful, and also more efficient.

The end result of RENNTECH's tuning program is an upgraded Dodge Sprinter that puts out 200 hp and 390 lb-ft of torque from 1600 - 2800 rpm. More importantly, however, customers have been reporting significantly improved fuel economy.

Hartmut Feyhl explains: "When you make an engine more efficient, it produces more power. This is what we have accomplished with the Sprinter, and many customers have reported getting significantly better fuel economy. We are waiting to have our figures confirmed by independent agents, but are seeing an improvement over 10%, almost 24 mpg at cruising speeds. This is approximately what Mercedes claims for the GL320 SUV, which uses the same engine."

With rising gas prices and an increased emphasis on fuel efficiency, RENNTECH believes their new ECU software makes sense for Sprinter-based RV owners and fleet managers motivated to "save some green by going green" - and with the introduction of a low-emission, flex-fuel racing engine and higher-mileage tuning software for Mercedes' V8 cars now on sale, RENNTECH is taking important steps towards becoming an environmentally responsible performance tuner.

Available for Dodge | Freightliner 3.0 CDI (2007 - ); contact RENNTECH for more.

renntech mpg tune






After kicking off 2008 by showing a new flex-fuel version of its XR50 rotary kart racing engine, RENNTECH - the South-Florida Mercedes-Benz tuning firm best known for building outrageously powerful automobiles for some of the world's pickiest car enthusiasts - claimed that its next-generation tuning software would focus on a "greener" sort of high-performance.

Today, RENNTECH began offering a "next-generation" ECU software package that improves horsepower while delivering impressive gains in fuel efficiency. On Mercedes' 3-valve V8 cars, RENNTECH is claiming a 2 mpg improvement at highway speeds, and an incremental improvement in city driving, all while delivering an additional 12-20 hp, depending on model.

Hartmut Feyhl, RENNTECH's president and ex technical director of AMG North America, believes RENNTECH's new software will further cement that message in the public's mind. "We have 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 processing power of the new engine computers, and allows us to make a number of small improvements that add up to a big 'overall' improvement," says Feyhl. "It really is that 'next-generation' sort of product that is much more advanced than what anyone was capable of offering before. Compared to earlier versions, our new software gives more power, better drivability, a smoother power curve, and even better gas mileage."

With a low-emission, flex-fuel racing engine and new "higher-mileage" tuning software now on sale, RENNTECH is taking important steps towards becoming an environmentally responsible performance tuner.
