GM Proving Grounds, Yuma, Arizona


LINK has access to the GM Desert Proving Grounds located in Yuma, Arizona. The facility is leased by General Motors from the US Army. The facility came fully online as of July 2009. The site contains an inner facility sitting on 2,400 acres with a 24-acre campus containing 98,000 square feet of building area and also has 40 miles of roadway. One of the main reasons that this site was chosen was the already imposed no fly zone which helps prevent unwanted photography of pre-production prototypes undergoing testing.
