Desert Proving Ground Yuma

32.91982°N, -114.32337°W

Desert Proving Ground Yuma is a facility co-built and leased by General Motors located within the US Army's Yuma Proving Ground, near Yuma, Arizona. The facility came fully online as of July 2009. The site contains an inner facility sitting on 2,400 acre with a 24 acre campus containing 98,000 sqft of building area and also has 40 mi 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. The facility is also used by the US Army for their own testing requirements.[1]

Other such features are:

• 3.5 mi circle track (3 lanes)
• 1.4 mi straight track (2–3 lanes)
• 3.1 mi Ride Road (2–4 lanes)
• 1000 x 1000 ft Dynamics Pad
