RENNtech CL65 Is the Fastest Mercedes Benz Once Again

On April 1st, 2011, RENNtech managed to recapture its long standing title of world’s fastest Mercedes Benz after the their 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 seconds at 137.46 mph (221.22 km/h) at Palm Beach International Raceway. This official time makes this CL 65 the fastest Mercedes on the planet, according to American tuner at least.

The CL65’s previous record of 10.51 seconds at 135.11 mph (217.44 km/h) was broken a week before that by a C63 running 125 shot of nitrous which logged a 10.41 seconds at 135.27 mph (217.69 km/h) run on March 25th, 2011. Not wanting to be outdone, RENNtech engineers went to work in the search for a few seconds here and a few extra horsepower there, but all 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. All this, plus the already modified ECU/TCU, carbon airbox, limited slip differential, high flow exhaust, drag radials, modified heat exchanger and intercooler pump, made for a potent little Merc rocket.

“RENNtech looks to continue shattering its 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,” the tuner states.

  • 60′ – 1.626
  • 330′ – 4.412
