We May Have Caught Apple Testing Its Autonomous-Vehicle Tech at Chrysler's Old Proving Ground

• For years, Apple fans have claimed a connection between the tech giant and Route 14 Investment Partners based on thin evidence.

• We visited Route 14's Arizona proving ground and spotted the company testing a car with a sensor stack with a design like one Apple has been testing.

• We also uncovered paperwork that appears to connect at least one individual to both companies.

In late 2005, DaimlerChrysler sold its proving ground in Wittmann, Arizona, to homebuilder Toll Brothers and its partners for $312 million. The new owners intended to use the 5500-acre property to develop a planned community with about 33,000 homes. It never materialized, and in 2010, the developers defaulted on their loan, leaving the proving ground in the possession of the project's lender, iStar.

After more than a decade of ownership, the commercial real-estate finance company finally unloaded the land, selling it to Route 14 Investment Partners LLC in July 2021 for $125 million. Route 14 Investment Partners was no stranger to the property. Approximately five years earlier, the New York–based iStar had begun leasing the proving ground to the little-known limited-liability company.

Much about Route 14 Investment Partners remains shrouded in secrecy, as there's minimal public information available about the presumably automotive-related company. However, rumors persist that Route 14 Investment Partners is a shell company for Apple's car project, once—and possibly still—known as "Project Titan."

Apple fans point to purported statements from unnamed sources confirming this, as well as the fact that Route 14 Investment Partners formed shortly after the tech giant's rumored car project first came to light in early 2015. They also note that both Route 14 Investment Partners and Apple use CT Corporation's Corporation Trust Company, which serves as a registered agent for companies that incorporate in Delaware, allowing businesses to take advantage of the First State's tax benefits without setting up dedicated offices there.

The fact that hundreds of thousands of other businesses, including Ford, Toyota, and Tesla, have used CT's services only emphasizes the circumstantial nature of this thin connection between Apple and Route 14 Investment Partners.

Autonomous in Arizona

Last month we flew to Arizona to visit Route 14 Investment Partners' proving ground in Wittmann. With little precipitation and lots of sunshine, the sleepy unincorporated desert community, located approximately 35 miles northwest of Phoenix, is conducive to autonomous-vehicle testing.

Based on what we witnessed while staking out the proving ground, we can confirm the presence of self-driving-vehicle technology at Route 14 Investment Partners' facility. We captured images of a white fourth-generation Lexus RX, sensor stack mounted to its roof, undergoing testing within the fenced-in perimeter of the proving ground.

More telling is the design of the sensor stack, which matches those that Apple has fitted to multiple Lexus RXs photographed in California. Pictures of these vehicles are all over the web, and many include a clear view of each vehicle's license tag—information we used to pull the vehicle identification number (VIN) for five of the California-registered Lexus SUVs.

We then crosschecked each VIN against those listed within California's 2022 Autonomous Mileage Reports. (The Golden State requires any autonomous-vehicle developer testing its technology on public roads to file data on system disengagements.) The result? All five VINs correlated with reports submitted by Apple.

Admittedly, it's possible that another company is toying with a similar sensor-pack design. Without any license plate or VIN information for the RX we spotted at the former DaimlerChrysler proving ground, our evidence, though stronger than a shared registered agent in Delaware, still seemed too weak on its own to convince a proverbial jury that this proves "beyond a reasonable doubt" that Route 14 Investment Partners is an Apple offshoot.
