The Toyota Arizona Proving Grounds (TAPG), Toyota’s proprietary U.S. vehicle development and testing facility, will become available to the broader industry as a vehicle testing resource as it officially launches the Arizona Mobility Test Center (AMTC) at TAPG.
According to a Toyota spokesperson, nearly 50 Toyota and Lexus vehicles for the North American market have been tested at TAPG since it opened in 1993, including the new 2022 model-year Tundra pickup truck.
Toyota tapped Intertek Transportation Technologies to operate the facility and provide tenant management and related services under a new multi-year agreement, while Toyota maintains ownership and continues its testing activities at TAPG.
Intertek provides the transportation industry with services that cover all aspects of the needs at AMTC, including staffing, scheduling, maintenance, security and overseeing all testing operations at the site. It will also market AMTC to attract tenants and manage the leasing business.
Part of AMTC will include an area of land for tenants to construct their own office and garage spaces as part of their facility usage. Toyota is also constructing its own new amenities, including expanded off road test facilities and a noise pass-by evaluation course, to provide new and world class facilities at AMTC.
Toyota is also maintaining its long-term commitment to support the surrounding community including support of Nadaburg Unified School District #81 in Wittman. Toyota will make another donation to help develop STEM education programming. Toyota is also donating to St. Mary’s Food Bank in Phoenix for addressing food insecurities.
The Arizona Mobility Test Center at TAPG is located in the Sonoran Desert near Wittman, Arizona, a town about 60 miles northwest of Phoenix. The facility covers approximately 11,650 acres and has 77 miles of testing surfaces with 25 miles of paved roads, 52 miles of dirt tracks and a high-speed oval.
