Just when you think you have seen it all, something like this comes along. This is just plain cool.
Haas CNC Racing… The NASCAR team, owned by Gene Haas, worked with Jacobs Engineering to develop a combination rolling road/wind tunnel that uses a steel belt to run the team’s vehicles up to 180 MPH, while at the same time, gaining readings from each individual wheel. Coupled with wind tunnel technology, the system can not only get the car’s wheels spinning, but can also thrust 2.85 million cubic feet of air over the vehicle every minute. – Autoblog
I have a few questions though. If you were going to spend all that money, why wouldn’t you spend a little more to build the thing in the ground? After all they are going for realism, and cars drive on the ground. I think the photo was taken while the giant treadmill wasn’t moving, because I don’t see any straps holding the car in place that you would usually see on a dyno.
