RENNTech’s 615HP Mercedes SL55 Is As Good As They Got In 2004 [w/Video] 12
Posted by Sergiu Tudose in AMG, mercedes, Mercedes SL, Mercedes Videos, Renntech, reviews, tuning on 12 12th, 2017

Back in the early 2000’s, if you couldn’t afford an SLR, the next best thing was the SL55 AMG, a supercharged V8-powered roadster packing a considerable amount of grunt.

Straight out of the box, it was good for 500 PS (493 HP) and a very impressive 700 Nm (520 lb-ft) of torque, before the first facelift came and added a little extra muscle.

Of course, those figures pale in comparison to what you had if you paid tuner RENNTech $108,000, which is what former baseball player Ray Durham did back then. Yep, this exact model used to be his car.

The tuner added a big brake kit, upgraded the suspension, made the exterior look more aggressive and, of course, fiddled with the engine. This example features RENNTech’sStage 6 conversion, which is good for 615HP, or 575 WHP, way more than you get even in a brand new SL65 flagship.

So what did The Smoking Tire’s Matt Farah think after driving this car? He found it very enjoyable (except for the slow gearbox), and even called it a great cruiser, although perhaps not ideal for twisty canyon roads due to its hot rod driving characteristics.


Renntech’s Mercedes-AMG E63 S Has 773HP, Hits 60 In 2.8 Seconds [w/Video] 9

The stock Mercedes-AMG E63 S is pretty impressive as it stands, with 604hp and 627lb-ft (850Nm) of torque, and a 0-60mph (96km/h) sprint made in just 3.3sec.

However, Renntech have improved this super saloon by applying their performance software, which the tuner claims unleashes the true potential of the car.

By modifying the throttle mapping, boost mapping, and ignition timing, optimizing air-to-fuel ratios, and increasing the rev limiter, the tuner has made the engine deliver an impressive 773hp and 778lb-ft (1,055Nm) of torque at the crank, and 665hp and 669lb-ft (907Nm) at the wheels.

Renntech’s tuned E63 S can now reach 60mph (96km/h) from a standstill just 2.79sec , which makes it 0.11sec faster than the new Porsche 911 GT2 RS. The 0-100mph (0-160km/h) sprint takes 6.61sec, and the quarter mile run is completed in 10.88sec, at 129mph (208km/h).

Despite choosing not to release an extensive image gallery of their latest product, Renntech have dropped a short video that shows just how fast their Merc’ AMG E63 S really is.


Renntech’s Mercedes-AMG GT R Is Unleashed With 761HP 13

Known usually as ‘The Beast of the Green Hell‘ thanks to Mercedes-AMG’s clever marketing campaign, this GT R has been turned into the ‘Orange Beast’ by tuning company Renntech.

And we’re not even talking about finishing it in orange and calling it a day, but also fitting it with BOV adapters, high-flow air filters, an ECU upgrade, and Stage II upgraded turbochargers.

When you add everything up, this Mercedes-AMG GT R is now good for 761hp (772PS) and 632lb-ft (857Nm) of torque, compared to the stock model that makes 577hp (585PS) and 516lb-ft (700Nm) of torque.

The tuner claims that the 0 to 60mph (96km/h) sprint takes just 3.0 seconds, an 0.5sec improvement, and the quarter mile is done in 10.7sec, at 136mph (219km/h), on a regular road surface, with the car sitting on the OEM Michelin Cup Sport 2 tires.

Renntech haven’t released any pricing details in the short text that accompanies the images, but owners of the Mercedes-AMG GT R, which can be had from an MSRP of $157,000 in the US, should find out how much they will have to spend on this aftermarket upgrade by contacting the tuner.


Renntech Bring Mercedes G550 4×4² To Its Fuller Potential, Or So They Say 3

Apparently squeezing an additional 102hp and 128lb-ft (174Nm) of torque from the 4.0-liter V8 engine that powers the Mercedes-Benz G500 4×4² makes it an "ultimate off-road machine" for Renntech.
