Here is some great video from the recent StreetCarDrags event of the record setting Tesla Model S P85D going heads up against a Mercedes E63s AMG.   The Tesla’s dual motors, instant torque (dyno sheet here),  691HP and AWD give it a decent advantage off the line and continuing on past the 1/8 mile. However as you’ll see in the GoPro view of race 2, the E63s with it’s lighter weight, 5.5L V8 BiTurbo and 577HP starts reeling in the P85D very quickly and at the end of the 1/4 mile the two are just hundredth’s of a second apart with the Tesla winning both Read More

AMS Performance  took their 2014 Mercedes E63 AMG S AWD to Great Lakes Dragway for some some passes down the 1/4 mile running an impressive 10.8 @ 129 MPH with 0-60 MPH coming in just 2.8 seconds.   Their E63 was equipped with a tune to increase boost as well as a set of downpipes and a cat-back exhaust system.  With these modifications we estimate increase of around 140 horsepower from the 5.5L V8 BiTurbo which would put this E63 well over 700HP. Coming soon is even more power for the E63 with AMS upgraded turbochargers, intercoolers and intakes which should Read More

As performance cars continue to become more and more powerful the point of diminishing returns comes up pretty quick when they are sending all that power to just 2 wheels. What’s the point of having 500-700 or even more horsepower if all you do is spin the tires when you try and use it. In the sports car world, the Nissan GT-R (545 HP), Porsche 911 Turbo S (530HP) and Lamborghini Aventador (700HP) are the kings, running 0-60 MPH in under 3 seconds with ease due to their AWD systems. Competitors like the Corvette ZR1 (638HP), Ford Mustang Shelby GT500 Read More

A RENNtech modified Mercedes-Benz SLR ran an amazing 9.76 @ 140.8 MPH at Palm Beach International Raceway last night capturing the records for being the quickest and fastest modern Mercedes in the world. This SLR was coming off the line super hard on Hoosier slicks with a 1.42 60′ time. We are waiting for the VBOX data to confirm, but we estimate this launch puts the SLR at around 2.2 seconds from 0-60 MPH. Power for this SLR was bumped up around 160 horsepower over stock with the host of RENNtech modifications. In stock form the SLR puts down around Read More

Here is a heads up drag race between a Lamborghini LP550-2 vs Mercedes CLS63 AMG BiTurbo.  The Lamborghini LP550-2 is a special edition of the Gallardo that is setup for rear wheel drive only powered by a V10 putting out 550HP.   The CLS63 AMG is the latest AMG from Mercedes-Benz with a 5.5L V8 BiTurbo motor putting out 518 HP.   The LP550 stomped on the CLS63 pretty easily which would be expected with it’s lighter weight and additional power. The LP550 ran 11.96 @ 123 MPH vs the CLS63 running 12.5 @ 116 MPH.  Take a look at the Read More

RENNtech has been working on turning up the power on AMG’s latest powerhouse the 5.5 liter V8 Twin Turbo (BiTurbo as per MB).  In stock form the 2012 CLS63 AMG with the new motor put down 473 horsepower and 468 ft-lbs of torque to the rear wheels on a DynoJet.   After the RENNtech ECU turning the power was bumped up to 569 horsepower and 624 ft-lbs of torque at the rear wheels. Using a conservative 15% driveline loss that puts this CLS63 at 669 horsepower which should be enough power for running low 11’s in the 1/4 mile with Read More

Motor Trend setup an amazing line up of cars for an all out king of the 1/4 mile drag race at an airstrip. The Nissan GT-R with it’s 530HP V6 Twin Turbo and superb all wheel drive launch control beat them all to the finish. Nissan GT-R: 11.2 @ 121.8 MPH Ferrari 458 Italia: 11.3 @ 125.6 MPH Audi R8 GT: 11.5 @ 125.1 MPH Mercedes SLS AMG: 11.7 @ 124.1 MPH Lexus LFA: 11.9 @ 123.7 MPH Chevrolet Corvette Z06/Z07: 11.9 @ 122.5 MPH Porsche 911 GT3 RS: 11.9 @ 120.7 MPH Ford Mustang BOSS 302 Laguna Seca: 12.4 Read More

Here is a RENNtech modified Mercedes McLaren SLR running 10.4 @ 133 MPH at Palm Beach International Raceway. This SLR is pushing over 600HP to the wheels by upping the boost pressure from the supercharger, a custom exhaust system along with cooling upgrades and tuning. Take a look at the timeslip, pictures and video below: Mercedes-Benz SLR RENNtech

GTBoard put up a video of a 2010 Porsche 911 Turbo with the PDK transmission running heads up from a roll against the Mercedes-Benz SL65 AMG Black Series. While the race was very close, it was surprising that the Porsche was able to jump ahead of the Benz each time when the race started, especially since the Mercedes V12 Twin Turbo Engine makes a lot more torque than the Porsche’s 6 cylinder twin turbo. After the initial 1 car or so jump of the Porsche, the SL65 Black Series hangs on and eventually starts pulling on the Porsche, although before Read More

Take a look at this stealth looking 2001 Mercedes-Benz CLK55 running a very quick 10.6 @ 125.9 MPH at Maryland International Raceway with a Kleemann supercharger pumping out 9psi. Additional modifications include a custom cold air intake using one of the headlights, Kleemann headers, full custom exhaust system and a PTE camshaft along with a larger throttle body. While the 1/4 mile time logs this CLK55 as the 2nd quickest street Mercedes around, the launch shown in the video, along with it’s 1.51 60′ time, breaks the Mercedes 60′ record by quite a bit. This CLK55 launches VERY hard using Read More
