Apple has reportedly hired Tesla's former Vice President of Vehicle Engineering, Chris Porritt, to work on "special projects". Given Porritt's background, which includes time as Aston Martin's chief engineer, Porritt could very well be working Apple's rumored car project, also known as Project Titan.

Apple reportedly hires former Tesla vehicle engineering VP

From 9to5mac:

He joins Apple a lot more quietly than with a press release. We are told by sources with knowledge of the matter at Apple that he joins the company as "Special Projects Group PD Administrator" – an intentionally vague title. Last year, Apple hired a senior engineer working on Tesla's Autopilot program, Jamie Carlson. He was also listed as a member of a special projects group.

Porritt is said to have worked on Tesla's Model S and X vehicles. He has a background in vehicle dynamics and architecture, and his expertise would likely prove invaluable on a car project. Porritt's supposed hire follows reports from earlier this year that Steve Zadesky, thought to be the lead on Project Titan at the time, was leaving Apple.
