Here's a GM's video showing the Z06 at the test track. Milford, Yuma, or ? Weather suggests might well be Yuma track, but does anyone recognize the track layout to be certain.

Here's some interesting background information on the different GM test tracks.

I have passed by the Yuma proving grounds on US 95 on my way to the town of Yuma. This is definitely not the Yuma proving grounds as the vegetation (trees and grass in the video) is not correct.

Finally found the Milford Proving Ground (MPG) track layout. The track layout map on the video confirms it was GM's Milford Proving Grounds. This had to be taken in the fall, for Michigan's weather the past two months has been snow on top of snow.

Watching the video, the Z06 is a race car with a provision for a license plate.
