Hot News!!! 2012 Mercedes-Benz CLS63 AMG tuned by RENNtech – Drag Video – 10.98 @ 129.40 mph (208 km/h) – First 2012 CLS63 to run 10s – Road Test TV

January 8th, 2012 by Road Test TV

As we predicted a few months back, the 2012 Mercedes-Benz CLS63 AMG will run the 1/4 mile in 10 seconds with minor modifications. For 2012 Mercedes offers a brand new 5.5-liter twin-turbocharged V8 rated at 518 horsepower and 516 pound-feet of torque in base form. AMG offers a “AMG Performance Package” option which raises the boost from 14.5 to 18.8 psi and results in an increase in horsepower from 518 to 550 hp, and torque from 516 to 590 lb-ft.

RENNtech, one of the leading tuners in the world, continues to raise the performance bar on all of its projects, including the 2012 CLS63. Last night, a RENNtech modified CLS63 making nearly 700 horsepower ran the 1/4 mile in 10.98 @ 129.40 mph (208 kmh), making it the World’s Fastest CLS63. This is the same CLS63 that ran 11.21 @ 126 mph with only a tune and drag radials about a month ago. Since the 11.21 pass, RENNtech added a RENNtech high flow exhaust and a limited slip differential. The launch method used was same as before which consisted of placing the transmission in S+ (Sport Plus mode), and launching off the line from an idle (Launch Control was not used). There are more mods to come from RENNtech, so stay tuned…… Enjoy the videos (We have included the video of the 11.21 @ 126 run for comparison).
