Toyota Motor North America has allocated more than $50 million for new vehicle and technology testing amenities at the Arizona Proving Grounds, reaffirming the company's long-term commitment to the site.
The investment includes the construction of a 5.5-mile oval test track, an off-road park, new ride and handling surfaces, and several other facility upgrades. Most of the construction is expected to be completed later this year. A future facility for the development of advanced driver assistance technologies is also planned.

Formally named the Arizona Mobility Test Center at Toyota Arizona Proving Grounds (AMTC at TAPG), the site has been available to third-party companies as a testing resource since 2021.
Expanded Capabilities for Vehicle and Technology Testing
“The new investment in Arizona signals the facility’s importance to Toyota,” said Stefan Young, vice president at Toyota Motor North America’s Research and Development. “Site updates make it more attractive as an ideal place for companies to test new vehicle capabilities, including by Toyota for our own North American-developed vehicle lineup, thanks to the new and expanded development capabilities.”
The current investment includes seven new development projects across the site, aimed at increasing testing flexibility and supporting emerging automotive technologies.

About the Arizona Mobility Test Center
Located in the Sonoran Desert near Wittmann, about 60 miles northwest of Phoenix, AMTC at TAPG spans approximately 11,650 acres. The site features 77 miles of testing surfaces, including 60 miles of paved roads and more than 50 miles of off-road and dirt tracks.
