- The facility previously belonged to a Delaware-based entity associated with Apple, which purchased it in 2021 for $125 million
- The complex features a 115-acre urban driving environment, a four-mile high-speed oval circuit, and specialized freeway testing infrastructure
- Apple previously utilized the location for Project Titan, its ambitious electric vehicle initiative that was discontinued in early 2024
- Waymo currently provides services across more than 10 American cities and is scaling its autonomous taxi fleet to tens of thousands of units
Alphabet’s autonomous driving subsidiary Waymo has acquired a massive 5,500-acre vehicle testing complex in Wittmann, Arizona, in a transaction valued at $220 million. County records from Maricopa show the sale was finalized on June 5.
The seller was Route 14 Investment Partners LLC, a Delaware-registered shell entity with ties to Apple. The transaction has been officially acknowledged by Waymo in statements to TechCrunch.
Apple originally acquired the property in 2021 in a deal worth $125 million. Prior to Apple’s ownership, Fiat Chrysler operated the site for hot-weather vehicle validation testing.
The tech giant leveraged the proving ground as a key asset for Project Titan, its secretive multi-billion-dollar endeavor to develop an electric vehicle. The initiative was ultimately abandoned in early 2024 following years of investment.
This Arizona acquisition represents Waymo’s largest closed-circuit testing venue to date. It surpasses the company’s current facilities at Castle Proving Ground in California and Ohio’s Transportation Research Center in both size and capability.
Comprehensive Testing Infrastructure
The expansive site provides diverse testing environments tailored for autonomous vehicle development. Key features include a 115-acre simulated urban environment, a 35-acre vehicle dynamics testing zone, a four-mile high-speed oval circuit, and purpose-built freeway infrastructure designed for self-driving technology validation.
A Waymo representative stated the facility will enable the company to replicate real-world driving conditions within a secure, controlled environment. The site will facilitate unmanned vehicle testing, motion dynamics evaluation, and operational crew training.
Waymo intends to leverage the property to accommodate future testing requirements as its autonomous vehicle fleet continues expanding.
Growing Autonomous Taxi Operations
Waymo initially launched testing operations in the Phoenix metropolitan area in 2017, beginning with trials in Chandler. This region subsequently became the company’s inaugural commercial autonomous taxi market.
The organization has now extended operations to over 10 metropolitan areas across the United States, including Los Angeles, San Francisco Bay Area, Austin, and Atlanta.
Waymo’s current fleet encompasses approximately 4,000 autonomous vehicles. The company recently introduced service using a new van platform manufactured by Zeekr.
These Zeekr vehicles are delivered to Waymo’s Arizona manufacturing facility, where technicians integrate the autonomous driving system. The company has announced ambitious production targets of tens of thousands of robotaxis annually.
This manufacturing roadmap encompasses both the Zeekr van platform and the Hyundai Ioniq 5. The newly acquired Arizona proving ground will serve a critical function in testing and optimizing these vehicles prior to deployment on public roadways.
Waymo operates as a subsidiary of Alphabet, the parent corporation of Google.
