Stellantis North America, more commonly known as Chrysler, operates proving grounds around North America for development and validation testing of new vehicles.
The Arizona Proving Ground is a vehicle test facility established in 1955 in Yucca, Arizona. It was owned and operated by Ford Motor Company based in Dearborn, Michigan, until Chrysler LLC announced on November 2, 2007 that it had purchased the facility for $34.9 million. APG is located at the foot of the Hualapai Mountains near Yucca, Arizona, 120 miles (200 km) southeast of Las Vegas, situated between Lake Havasu and Kingman, Arizona.
The facility was originally Yucca Army Airfield, an Army Air Corps training base, used during World War II. The field was declared surplus land by 1946 and the ownership was turned over to Ford in 1954.
Harley-Davidson Motor Company has entered into an agreement to use the vehicle test facility to test their motorcycles. Harley-Davidson currently occupies several buildings at the test facility, including at least one they custom built.[1]
