Toyota Motor North America has announced a significant investment exceeding $50 million for the enhancement of its Arizona Proving Grounds. This development involves constructing new amenities aimed at advancing vehicle and automotive technology testing. The facility will feature a 5.5-mile oval track, an off-road park, and various ride and handling surfaces. Most construction is expected to conclude by the end of this year.
Stefan Young, Vice President at Toyota Motor North America’s Research and Development, stated, “The new investment in Arizona signals the facility’s importance to Toyota.” He added that the site updates make it an attractive location for companies to test new vehicle capabilities.
Managed by Intertek Transportation Technologies since 2021 under a management agreement, the Arizona Mobility Test Center at Toyota Arizona Proving Grounds (AMTC at TAPG) has served as a resource for industry vehicle testing. It has hosted 37 organizations with approximately 286 test vehicles conducting about 203,400 hours of testing.
Arizona Governor Katie Hobbs commented on this development saying, “Again and again, Arizona is proving why businesses move to, stay in, invest in our state.” She expressed gratitude towards Toyota for its contribution to innovation and opportunity in Arizona.
Leo Biasiucci, Chairman of the Arizona House Transportation and Infrastructure Committee also remarked on the investment stating he was proud that Toyota chose Arizona as its home.
Located near Wittmann in the Sonoran Desert about 60 miles northwest of Phoenix, AMTC at TAPG covers around 11,650 acres with extensive testing surfaces. Established by Toyota in 1993, it has been integral to testing over 50 Toyota and Lexus vehicles intended for the North American market.
Toyota continues its commitment to sustainable mobility through advancements in next-generation vehicles and innovative concepts. The company employs nearly 64,000 people across North America contributing significantly to design and manufacturing efforts. Its plant in North Carolina is set to commence production of automotive batteries by spring 2025.
