Waymo has acquired a 5,500-acre automotive proving ground in Arizona for $220 million, significantly expanding its autonomous vehicle testing capabilities as the company accelerates the growth of its robotaxi operations across the United States, TechCrunch reported.
According to property records filed with Maricopa County, the Alphabet-owned autonomous driving company purchased the facility from Route 14 Investment Partners LLC, a Delaware-based entity associated with Apple. The transaction was recorded on June 5.
Major Expansion of Testing Infrastructure
Located in Wittmann, Arizona, the proving ground is one of the largest dedicated vehicle testing facilities in the United States and substantially increases Waymo’s closed-course testing capacity.
The site includes a 115-acre simulated urban environment, a 35-acre vehicle dynamics testing area, a four-mile high-speed oval track, and a dedicated freeway course specifically designed for autonomous vehicle development and validation.
A Waymo spokesperson said the facility will be used to create controlled driving environments that support the ongoing development and validation of the company’s self-driving technology.
Testing activities are expected to include rider-only operations, motion-control evaluations, operational training programs, and future expansion of autonomous vehicle testing activities.
From Fiat Chrysler to Apple and Now Waymo
The facility has a long history within the automotive industry.
Originally developed as a proving ground for Fiat Chrysler, the site was used to evaluate vehicle performance, components, and durability under demanding conditions, including high-temperature testing.
Apple acquired the property in 2021 for approximately $125 million after leasing access to the site for several years.
The technology company used the facility as part of its long-running automotive initiative known as Project Titan, which explored various concepts for electric and autonomous vehicles.
Apple ultimately canceled the project in early 2024 after investing billions of dollars in vehicle development efforts.
The acquisition allows Waymo to take ownership of a facility specifically designed for advanced vehicle testing rather than constructing a new proving ground from scratch.
Supporting Rapid Fleet Growth
The purchase comes as Waymo continues to expand both its autonomous technology development and commercial robotaxi operations.
The company currently operates a fleet of nearly 4,000 autonomous vehicles and recently began introducing a new autonomous vehicle platform based on vehicles supplied by Chinese automaker Zeekr.
Waymo has also stated plans to scale production to tens of thousands of autonomous vehicles annually, including future deployments based on both Zeekr vehicles and the Hyundai Ioniq 5.
Vehicles are shipped to Waymo’s Arizona production facility, where they are equipped with the company’s proprietary autonomous driving system before entering testing and commercial service.
Strengthening Arizona Presence
Arizona remains one of Waymo’s most important operational hubs.
The company began testing autonomous vehicles in Chandler, a suburb of Phoenix, in 2017. The Phoenix metropolitan area later became Waymo’s first market to launch a commercial driverless ride-hailing service.
Since then, the company has expanded operations into more than ten U.S. cities, including Los Angeles, the San Francisco Bay Area, Austin, and Atlanta.
The acquisition of the Wittmann proving ground further strengthens Waymo’s presence in Arizona and provides a significant long-term asset as the company works to scale autonomous vehicle deployment.
With dedicated freeway, urban, and high-speed testing environments available at a single location, the facility is expected to play a central role in the development and validation of future generations of Waymo’s autonomous driving technology.
The deal also highlights the growing demand for large-scale testing infrastructure as autonomous vehicle companies transition from research programs to commercial transportation networks.
