VW Factory cD is something between .30 and .33 - it's already fairly low for a 2000 notch back.
I have lots of numbers from my own work... But I am purposely not reporting them. I don't like the numbers, they're too low, so I'm rejecting their validity. That's science for ya
I have, however, been using them barometrically.
It's my goal to attempt empirical measurements in an ABA fashion - but not using a ScanGauge. Ideally/Dangerously, I'd like to tow the vehicle with a force gauge inline. Tow at slow velocity for mechanical losses and at high velocity for aero measurements... I've done this with great success with HPV's - but cars are a very different animal with much higher velocities o.0 I forgot to mention, recently I've got access to a VAG-COM
