HOT!!! 2012 Nissan GTR vs 2012 Mercedes Benz CLS63 AMG with RENNtech tune – Drag Video – 11.21 @ 126.3 mph (203 kph) – Road Test TV

December 2nd, 2011 by Road Test TV

We finally got a little cooler weather here in South Florida (high 60s – low 70s) and had the opportunity to make a few passes down the quarter mile in another 2012 RENNtech CLS63 at Palm Beach International Raceway.

To give some background, for 2012, AMG has upped the ante with the CLS63 by adding a new direct injected BiTurbo V8. The base 5.5 liter V8 Bi turbo is rated at 518 horsepower and 516 pound-feet of torque at the crank. In addition, AMG offers a “Performance Package” for those who want more. The “Performance Package” raises the boost on the turbos from 14.5 psi to 18.8 psi. As a result, horsepower jumps from 518 to 550 and torque from 516 lb-ft to 590.

We found out that Mercedes Benz was very conservative with its horsepower ratings, because on a Dynojet dynamometer at RENNtech, the new 5.5 liter V8 BiTurbo in base form made 556 horsepower and 550 ft-lbs of torque (473.24 horsepower and 468.22 ft/lbs of torque at the wheels). Note, this was the base CLS63 that is rated at 518 hp and 516 ft/lbs of torque. But this motor makes some serious power with a tune. With a RENNtech tune only, the base CLS63 made 669 horsepower and 734 ft-lbs of torque (569.13 horsepower and 624.94 ft/lbs of torque at the wheels) DYNO RESULT HERE.

Back to the dragstrip…… So, during the run in the video below, we had the opportunity to line up against a 2012 Nissan GTR. As everyone knows, not too many vehicles can hang with a Nissan GTR with its eyeball flattening 0 to 60 times. However, the big 4400 lb, 4 seater 2012 CLS63 more than held its own against Godzilla, running an amazing 11.21 @ 126.3 mph (203 kph) to the GTRs 11.11 @ 124 mph (200 kph). Enjoy.
