On April 25, 2010 in 90 degree weather with a 15 + mph head wind, a RENNtech modified CL65 with stock turbos and stock intercoolers went a blistering 191.186 MPH in the standing mile held in Miami during the Exotics Rally event.

The bad Benz did have the following RENNtech modifications: ECU/TCU, Ram Air, High Flow exhaust with 200 cell cats, upgraded intercooler pump and limited slip differential.

This is the same RENNtech CL65 that holds the quarter mile record of 10.62 @ 133.7 mph. It appears that this Benz may hold a couple of new records: fastest CL65 in the standing mile and the fastest Benz with stock turbos in the standing mile.

This past weekend RENNTECH participated in a Standing Mile event at the Dade-Collier airstrip. There was a fairly decent turnout and our tuned C63 drew all sorts of attention. Last week, we fabricated some unique aero enhancements in-house for this event. These exterior additions bumped the cars standing mile speed up nearly 9mph - 185MPH! Proving that aerodynamics has just as much an effect on a vehicles ability to “go fast” as its actual performance output. Here are a few pics and a video of the C63 in "standing-mile trim".
