Man, how crazy is this? While wind tunnel testing is perfect for planes and other flying vehicles at times they’re not so perfect when dealing with cars, especially at very high speeds. The road surface sometimes leads to incorrect readings since wind travelling at 200+ mph likes to stick to the floor. So for a more accurate way to test their cars the Haas CNC Racing NASCAR team has created this full-size rolling road testing facility called WindShear Inc.
That track is actually a 1mm thick steel belt capable of rolling at over 180 mph! It has sensors located underneath that can take readings for each wheel and the whole setup seen here will be used inside a massive wind tunnel to accurately recreate the driving conditions on a NASCAR track. Minus of course the left-hand turns.
A larger picture of the testing rig is available after the jump that better shows the scale of this setup.
