CLS63 Biturbo New Record- 10.98 @129.40 mph!

Monday, January 9th, 2012

RENNtech’s 2012 CLS63 broke the 11 second barrier by running the 1/4 mile in 10.98 @ 129.40 mph (208 kmh)! This officially makes it the world’s fastest CLS63.

Our latest run surpasses our previous 1/4 mile time in the same vehicle with a previous record of 11.21 @ 126 mph with only a tune and drag radials posted last month. Since then we have added a RENNtech 100% locking limited slip differential and an in development performance exhaust modification in addition to our performance ECU upgrade. The new biturbo engine now makes 688 crank horsepower and 765 lb/ft of torque; transforming the CLS63 into an all out road rocket!  The vehicle made the pass in S+ (Sport Plus) and made the run from idle without launch control activated.

World Fastest Mercedes Record Regained By RENNtech

Thursday, April 7th, 2011

On April 1, 2011, RENNtech regained their long standing title of worlds fastest Mercedes Benz. Our RENNtech modified CL65, which held the long standing previous record once again reigned supreme by shattering its previous best quarter mile time with an unprecedented  run of 10.27 @ 137.46 mph at Palm Beach International Raceway. This official time makes our CL 65 the fastest Mercedes on the planet.

The previous record of 10.51 @ 135.11 mph, also held by RENNtech’s CL65, was broken just last week by a C63 running 125 shot of nitrous which logged a 10.41 @ 135.27 mph run on 3/25/2011. Not one to be bested and looking to regain the title; RENNtech went back to work in search of even more from the CL 65 with further improvements and without the use of nitrous. Modifications to the CL 65 included an even more aggressive race only tune, enhanced drive line modifications such as upgraded transmission internals and a prototype torque converter and additional light weighted vehicle components. These are in addition to the already installed RENNtech modified ECU/TCU, carbon airbox, limited slip differential, high flow exhaust, drag radials, modified heat exchanger and intercooler pump.

RENNtech CL 65 QUARTER MILE BREAKDOWN

  • 60′ – 1.626
  • 330′ – 4.412
  • 1/8 – 6.682
  • MPH – 108.99
  • 1000 – 8.629
  • 1/4 – 10.274
  • MPH – 137.46

RENNtech looks to continue shattering our own records and will be further modifying the CL in search even more performance in pursuit of the first 9 second Mercedes Benz. Congratulations to Steve C., car owner and driver, on this incredible achievement.
