The Toyota Arizona Proving Ground is a nearly 12,000-acre facility in the Sonoran Desert that encompasses paved roads and off-road trails.
The Toyota Arizona Proving Ground, also known as TAPG, was established in 1993. TAPG covers 11,650 acres of land in the Sonoran Desert and is located close to Wittman, Arizona, a very small town with a current population of 238. The nearest city to TAPG is Phoenix, Arizona, which lies about 60 miles southeast of Toyota’s proving ground.
Contained within TAPG is the company’s largest testing facility, which includes 60 miles of paved roads, as well as over 50 miles of dirt and off-road tracks. It’s also home to a 10-mile paved oval. Since its opening, more than 50 Toyota and Lexus vehicles destined for the North American market have been put through their paces and refined for production at TAPG. Some of the vehicles tested there include the tiny Scion iQ, the 2019 Toyota Avalon, and Lexus‘ flagship sedan, the LS 500, which we found to have a smooth, refined ride and luxurious cabin when we reviewed the 2024 model.
