RENNtech is making progress on one of this year's most sought-after supercars, the Mercedes-Benz SL65 Black Series. Initial ECU programming results on the twin-turbo V12 were remarkable. And after further testing and development RENNtech massaged 630 HP / 765 LB-FT at the wheels on the in-house dyno. In the case of this particular dyno run that's 67HP/69LB-FT over stock. Helping to plant that tire-liquifying power to the ground is a custom 100% locking limited-slip differential.
RENNtech will continue to pump up the SL65 Black Series and expects to have even more substantial numbers as R&D progresses. Stay tuned!

The R.A.T. is shipped out preprogrammed with RENNtech’s list of firmware and can be sent anywhere in the world. When first plugged into your Mercedes-Benz via the OBD II port, the tuner “marries” itself and uploads the proper file. If the proper file is not already available or you would like to have a custom file made, simply plug the R.A.T. into your computer. The vehicle data is sent to RENNtech and, after being tested, your new file is emailed back to you. If you lose power or the R.A.T. is disconnected while uploading the file, the tuner is designed to automatically recover the stock programming.
The R.A.T. is available for the Mercedes-Benz E55 and 2006, or earlier, Mercedes V12 Turbos. See our website for more info.

The March 2009 issue of Mercedes Enthusiast magazine features a blast from RENNTECH's past; a surly 1997 RENNTECH E60 RS with quite the pedigree. Built for actor/comedian Jerry Seinfeld, this vehicle appears to be the sole tuner-concocted MB to call the Irvine, CA Mercedes-Benz Classic Center USA its home.

Not content to sit on the sidelines while the world watches Ferrari, RUF, and others debut their new supercars, Mercedes-Benz release a full, 35 picture gallery of hi-res "spy" photos of their upcoming SLC/SLS "gullwing" supercar. The SLR McLaren successor promises to be just as fast as the outgoing SLR, addressing that car's weight issues and being more "true" to Mercedes' heritage.
RENNTECH will have tuning upgrades available at the time of launch. Contact RENNTECH for more information.

2009 marks two special birthdays: it is RENNTECH's 20th year in business and the G wagen's 30th year of production! As previously mentioned HERE, RENNTECH is celebrating its 20 years of tuning excellence with a series of extremely limited-production specials that set new industry standards for Mercedes-Benz performance tuning.
The concept shown makes use of a RENNTECH-tuned Mercedes-Benz CDI Diesel, which makes almost 400 lb-ft of torque in production tune. Final output TDB.
As with RENNTECH's GLK hybrid rally-racer and 777 SLR renderings, these were done by Platune Design.

Last week, some of our RENNTECH customers spent some time running a pair of RENNTECH-tuned AMGs down Palm Beach International's new 1/4 mile drag strip - and the results were impressive: an 11.654 time at over 120.70 mph on Nitto Invo street tires!
Watch for the timeslip below to get posted on to Dragtimes in the coming days, as well as slips from the E55 AMG that came along, and was kind enough to take some pics for us.

The recently mis-named Autoweek website recently posted new spy photos of Mercedes-Benz' upcoming SLC gullwing revival, which is set to become the company's successor to the SLR McLaren.
We are big fans of the SLR, and these latest images show some very SLR-like taillamps and rear fenders ... all good things.
CLICK HERE for the original gallery, and expect to see the finished car at Geneva in March.

RENNTECH's new $3995 performance PKG1 for the 05-08 SLK 350 boosts the output of the 268 hp V6 to over 300 hp. That's 40 horsepower for under $4000!
This level of performance and torque comes from new RENNTECH headers and a RENNTECH ECU upgrade, which also raises the car's top speed from the factory-limited 155 mph to over 170 mph. As the copy above states: this package will change the way you look at Mercedes' 350 series cars.
Currently available for 05-08 SLK350 and GLK350

RENNTECH was once again a part of the Pine School's "100 years of cars" auto show, where we displayed our 2008 SEMA award-winning GLK hybrid rally-racer.
The GLK (above) was in good company, with several unique exotics and historic automobiles also in attendance, including Enzo Ferrari's own Alfa Romeo road car (below) as well as an authentic Berger F1 Ferrari and the first Alfa Romeo 8C to land in Florida.

The RENNTECH GLK 350 Spec.R hybrid rally-racer we built for SEMA just came back from the LA Auto show. Fresh from the tuner build-off win, RENNTECH's rally-racer has been making a big splash here in the US ... now it looks like the European press is getting behind the RENNTECH GLK!
Mercedes will show the GLK again at the Chicago show this February, and it will be on display at select Mercedes-Benz dealers across the US through this spring.

RENNTECH has just put the finishing touches on a new exhaust system for the Mercedes-Benz CLK63 AMG Cabrio. The single-out exhaust for this car (and the previous CLK55 AMG) was never a fan-favorite, but with RENNTECH's new sound-pipe and deep, muscle-car growl, it soon will be!
Click the link, turn up the speakers, and enjoy.
Last weekend (24 Jan) Privilege invited RENNTECH to be a part of the 4th annual Palm Beach Supercar Weekend - and RENNTECH was be there in force, with our award-winning GLK 350 Spec.R hybrid rally racer, 20th Anniversary C63 program car (580 hp), and a customer SL600 (shown) and S550.
We had a great time, and enjoyed walking through the crowds and admiring the Ferraris, Lamborghinis, Moslers, and other exotics (the Moslers and Rossions were our favorites ... after the RENNTECH Mercedes, of course!).

RENNTECH will be celebrating 20 years of performance without compromise next Saturday night, January 31st at the Hard Rock hotel and casino's Pangaea Lounge in Hollywood, Florida. There will be drinks, music, models, and - of course! - RENNTECH Mercedes, including the award-winning RENNTECH GLK 350 SPEC.R Hybrid rally racer.
We'll issue a formal press release soon.
January 16, 2009
Earlier this week, AMG boss Volker Mornhinweg announced “the horsepower war is over". If this sounds familiar, it's because AMG issued a similar press release LAST JANUARY.
"Last year, it was a coincidence that we were releasing a new, 695 hp performance package for the 65 series AMG cars at around the same time. We sent out a press release that said 'War Not Over'," recalls Hartmut Feyhl, president of RENNTECH and four-star General of the horsepower wars. "This year it is the same timing again, and we have something much more extreme to announce for our 20th Anniversary."
Feyhl founded RENNTECH in 1989, and the company has since established itself as one of the world's premier tuning firms and the foremost authority on Mercedes-Benz performance tuning. 2009 marks the company's 20th year in business, and the company intends to celebrate by releasing a small number of extreme, limited edition performance vehicles, beginning with the 777 hp, RENNTECH 777 shown here.
"This 777 concept is really an all-new car that makes use of the advanced carbon fiber chassis of the SLR McLaren. It can be described as a street-legal track car, or something closer to what the enthusiasts were hoping for from the SLR, originally - which is more a successor to the McLaren F1."
RENNTECH heavily revised the SLR McLaren bodywork and aero package using some of the same technology the company used to develop the the GLK Hybrid Rally Racer for Mercedes-Benz, including advanced CFD software to develop the aerodynamics for improved downforce. Even with the big wing, splitters, and skirts, a top speed in excess of 210 mph is well within reach for the 777.
The 777 is much more than lightweight bodywork, however. The 5.5 L supercharged "Kompressor" v8 engine is heavily revised, with internal and external performance upgrades and a significantly upgraded cooling system.
Getting that power to the ground is the job of a fully redesigned suspension and driveline, with a heavily reinforced transmission sending power to RENNTECH's revolutionary new limited-slip differential. Built for RENNTECH by Japanese supplier OS Giken, the recently-released differential allows for 100% locking between the drive wheels for unsurpassed mid-corner traction. Aggressive Nitto NT-05 ultra-high performance tires wrapped around extremely lightweight, 1 pc. center-locking wheels round out the street -legal handling package.
"The 777 will be a very special car," explains Hartmut. "The first example is being built now, and will be ready this Spring. We intend to build a few different extreme vehicles like this for our 20th anniversary, with each one being strictly limited to 20 units. They are all very exciting projects, and we will be announcing them throughout the year, as they approach completion."

The video above shows a fantastic Switzer-prepared SLR McLaren coupe putting out 600 hp at the wheels - that's almost 750 hp at the crank!
This SLR makes use of RENNTECH's SLR PKG1 performance upgrades and the latest version of the RENNTECH's SLR McLaren software. Each SLR engine is assembled by hand at AMG, of course, and there are sometimes slight variances, but this is still a STRONG build - Switzer (our primary Ohio dealer) did a fantastic job getting the most out of this McLaren on pump gas (RENNTECH advertises 722 hp, or just under 580 hp at the wheels).
Dyno sheet (below) provided by SPI.
Global Motors' photographers have snapped the clearest pictures yet of the upcoming CLK successor from Mercedes-Benz. Called the E coupe, the car take styling cues from the future-classic CLS class, which launched the current wave of 4-door coupes from Audi, Volkswagen, Aston Martin, and BMW.
Expect some new chassis and brake innovations from the AMG model, as well as a Bluetec diesel version. CLICK HERE for the original article and hi-res photo gallery.

I was browsing some the RENNTECH customer cars that have posted timeslips on Dragtimes (for those of you not "in the know", Dragtimes is THE resource for real-world performance numbers, with visitors from all over the world posting timeslips, videos, and photos of real cars, putting down real numbers) and stumbled across this fantastic picture of a RENNTECH-tuned S65 (w220) AMG Mercedes barreling through the 1/4 mile speed traps at almost 130 mph!
While we've been discussing this run for some time (the big S' timeslip shows that this epic run took place in late 2006) this is the first time I've seen this photo.
CLICK HERE to see RENNTECH's available w220 S class tuning products ... and if you can beat that 11.0, add it to Dragtimes!

Welcome to 2009, everyone!
We had a very successful 2008, winning the Mercedes-Benz GLK tuner build-off at SEMA, introducing a new website in July, welcoming new dealers to the fold, and more! All the same, 2009 is going to be EVEN BETTER ...
2009 marks RENNTECH's 20th year in business - and we'll be hosting a few events and launching a few new models in the coming months to celebrate the last 20 years, and also to take a look back at some of the projects that have established RENNTECH as the world's premier Mercedes-Benz performance tuner.
Thank you for visiting our site and - from everyone at RENNTECH - have a happy new year!
