Rumor has it that Apple aims to release its electric car in 2019.
The company reportedly has around 600 employees working on Project Titan, with that number bound to grow.
And Apple has purchased several web addresses related to cars, including apple.car and apple.auto
There are reports of it being developed in a secret lab in Berlin, Germany.
But Apple could also be looking at building the vehicle — widely referred to as either the Apple Car or the iCar — in Vienna, Austria.
There are also facilities in Sunnyvale, California that are thought to be dedicated to Project Titan.
It's also worth noting that Apple "basically owns an entire hill in Ireland" where it may be working on the car.
The tech giant has also inquired about using GoMentum, which is a testing station that's been used by Google and Tesla.
Ok, so there's a lot of places that could be housing the project, but what about the car itself? There are reports that the prototype Apple is working on resembles a minivan, but that could very well change.
It'll probably be very connected. “When I look at the automobile, what I see is that software becomes an increasingly important part of the car of the future," Tim Cook said of cars of the future in October.
In addition to being electric, the car could also be self-driving.
The rumor that the Apple car could be autonomous is further supported by comments an Apple source made that the car "will change the landscape and give Tesla a run for its money."
And we know that Apple has met with officials from California's Department of Motor Vehicles to discuss the state's regulations for autonomous cars.
But Apple has reportedly had a difficult time getting an automaker to help develop the car, with BMW and Daimler rejecting the tech giant's offers.
Although there are reports Apple may be teaming up with vehicle engineering and contracting firm Magna, which is based in Vienna, Austria.
In the meantime, Apple has hired quite a few automotive experts, like Tesla's vice president of vehicle engineering Chris Porritt, pictured below.
Tesla's Elon Musk has even commented on how many employees have gone to work at Apple.
