Electrek noted that Schwekutsch has extensive experience in developing electric drives, and not just at Tesla. He played key roles in the second-generation Roadster and Semi, but he also contributed to the BMW i8, Porsche 918 Spyder and Fiat 500e, including EV and hybrids. He will probably continue on that road to Apple then.
This does not necessarily mean that Apple is back to produce its awesome car. Apple is believed to be partnering with VW on autonomous shuttle buses that would move employees between their offices. The rent can be focused on fulfilling it and any other transportation work. Schwekutsch would be an unusually high profile for a narrowly focused effort, though, and the time of his rent (he both left Tesla and came to Apple in March) suggests he might have been poached. Whatever he does, Apple thinks he's important.
