The last Apple announcement was a snore, but that doesn’t mean the tech giant doesn’t have more moonshots in development. Rumors about an Apple car have been circulating for a few months. But according to new documents obtained by The Guardian, those rumors may be a lot closer to becoming a reality than previously thought.

The documents reveal that employees of Apple’s Special Projects group met with representatives from GoMentum Station, a self-driving and connected vehicle testing facility housed on a former naval base, last May. Apple also met with the California D.M.V. in August to discuss state regulations surrounding autonomous cars.

Apple has about 600 people working on what it has dubbed Project Titan and hopes to have some kind of car product ready by 2019, according to the Wall Street Journal. It is unclear whether it will be a self-driving car, an electric car, or both. (It seems we will still have to wait a little longer for a Jetsons-esque flying car.)

Other automakers are certainly taking notice. At the recent Frankfurt auto show, Daimler CEO Dieter Zetsche said, “We do not plan to become the Foxconn of Apple,“ referring to his company’s desire to avoid being a mere subcontractor making products that feature Apple’s coveted software.

In keeping with its culture of secrecy, Apple declined to comment. One of the main selling points of the GoMentum testing facility is its high security. The location is ringed with barbed wire and patrolled by armed guards.
