Desert Proving Ground Yuma

32.919818°N 114.323366°W / 32.919818; -114.323366

Desert Proving Ground Yuma is a facility co-built and leased by General Motors located within the US Army's Yuma Proving Grounds, near Yuma, Arizona. The facility came fully online as of July 2009. The site contains an inner facility sitting on 2,400 acres (970 ha) with a 24-acre (9.7 ha) campus containing 98,000 square feet (9,100 m²) 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. The facility is also used by the US Army for their own testing requirements.

Other such features are:

Milford Proving Ground

42.583603°N 83.684449°W / 42.583603; -83.684449

The General Motors Milford Proving Ground was the industry's first dedicated automobile testing facility when it opened in 1924. It is located in Milford, Michigan and covers 4,000 acres (16 km²). 4,800 staff work in its 107 buildings today. The proving ground includes the equivalent of 132 mi (212 km) of roads representative of conditions found on public roadways and other specialty surfaces for vehicle testing. Some roads are open only to drivers who have passed special performance driving training. The saying goes that each mile driven on the grounds is the same as 5 miles (8.0 km) in the real world.

Facilities

• The VDTA ("Vehicle Dynamics Test Area"), also known as "Black Lake", is a 67-acre (270,000 m²) pad of blacktop for vehicle dynamics testing. Waterfowl have been known to try to land on this "lake" of asphalt. At the ends of the VDTA are two semicircle tracks used for accelerating vehicles up to high speed before entering the pad. A controlled low-friction area made of ceramic tiles is on one side of the pad. Another area is coated with the asphalt sealant Jennite and can be watered down to produce a low friction surface.
• The Oval Track is a 3.8 mi (6.1 km) circuit
• The Circle Track encloses the VDTA and is a 4.5 mi(7.2 km) banked circle. It has five lanes posted with speed limits increasing towards the outermost lane. The speed limit for the outermost lane is 100+ MPH (192  km/h). Due to the banking, each lane can be driven at its posted speed all the way around the circle without needing to touch the steering wheel, given proper wheel alignment and tire pressures. The track surface is extremely hard "dolomite" concrete for wear resistance.
• The North/South Straightaway is 6.225 mi (10 km) miles in total length and includes two 2.5 mi (4 km) straightaways
• The East/West Straightaway is 3.1 mi (5 km) miles around and includes two 1.2 mi (1.9 km) straightaways
• "Seven Sisters" is a short course featuring seven tight curves, some level, some banked. It is one lane that can be driven in both directions, so only one car is allowed on the course at a time. This is used for testing vehicles under transient lateral acceleration loads.
• 12 Mile Road is a straight section of pavement which duplicates the historical surface texture of a section of 12 Mile Road near Detroit.
• The Ride and Handling loop is enclosed by the Circle Track and has varied surfaces and turns.
• The Vehicle Safety & Crashworthiness Lab includes a recently added rollover test facility.

Cupuán Proving Ground

18.783056°N 102.168611°W / 18.783056; -102.168611

General Motors Proving Ground Cupuan del Rio is situated between Lázaro Cárdenas and Uruapan, Michoacán, Mexico. The facility opened in 2006 and features a circle track, several off-road courses, and is primarily used for testing HVAC systems.

As of 2011 the grounds are mostly abandoned, and only a local security staff remains. This is due to the volatile, potentially unsafe situation in the region and the access routes to/from Cupuán.

General Motors Cruz Alta Proving Ground at Indaiatuba, Brazil [1]

• Founded in 1974
• Proving Ground facilities
• It is the largest and most comprehensive proving ground in Latin America, and the second largest in the General Motors Corporation. It comprises the most advanced test tracks, which precisely replicate the most varied and demanding road conditions. [2]
• GM do Brasil is committed to the preservation of forests and the animal species that live there. Cruz Alta Proving Ground for example, has test roads and tracks that sit amid a forest reserve of 4.6 million square meters, including 2.27 million square meters of reforested trees. The Proving Ground also features 100,000 square meters of Atlantic Forest original vegetation; 10,000 planted fruit trees and more than 1 million square meters of lawns. In addition, GM do Brasil recently partnered with IBAMA, the Brazilian Environment Protection Agency, to monitor the abundant proliferation of capybaras at that location.
