2011 RENNTECH BMW X5M sets record as World’s Fastest “TUNE ONLY” X5M – ROAD TEST TV

November 10th, 2011 by Road Test TV

Last night at Palm Beach International Raceway, we caught up with the crew from RENNtech doing some more R&D on their BMW X5M project. RENNtech’s goal was to have the fastest “tune only” BMW X5M and to be the first “tune only” X5M to run in the 11s with stock exhaust, stock (heavy) run-flat tires and stock airboxes. Well, their efforts paid off.

Even though conditions were not optimum (90% humidity and a DA of 1000 feet), the RENNtech X5M ripped to 60 mph in 3.75 seconds; reached 100 mph in 9.2 seconds, and went through the traps at the end of the 1/4 mile in 11.995 seconds at 114.05 mph. Considering that an X5M weighs well in excess of 5000 lbs without a driver, it is clear that the RENNtech X5M is making some serious power.

We asked the guys from RENNtech what’s next for the X5M, and were told that they will be doing hardware changes in phases. The modifications will include downpipes, an Akrapovic exhaust, modified airboxes, and bigger turbos.

The quick Nissan GTR in the left lane has gone a best of 10.94 at 128 mph, and is running a Cobb tune modified by HPLogic. It also has a midpipe and Michelin PS2s tires.
