Hitzinger and his team provided Porsche with an excellent racer, which won Le Mans overall in only its second year (and again in its third year), proving his value. Which is precisely why it was a surprise to all involved that Alex announced he was leaving Porsche in March of this year.
For months, nobody knew where he ended up or why. Thanks to a report from Manager Magazin released last 16 December, everyone now know that Hitzinger was lured away by tech giant Apple.
Apple, of late, have been assembling a series of automotive specialists as they ramp up toward building their own car. It is possible that Hitzinger was needed because of his experience with lightweight carbon fiber manufacturing and electric power delivery and energy recovery, gleaned from years in the motorsport industry.
He is also well versed in engineering a completely new technologically advanced program from scratch, as he had done at Porsche. It is likely that this type of thing interests Apple, as they were also in talks to purchase McLaren in early 2016, likely for similar reasoning.
What will the Apple Car look like when it finally does come to fruition? Will they start as Tesla did with an electric sports car, or will it be a self-driving bubble like Google's car? Something in between perhaps?
It is particularly interesting to view Hitzinger's LinkedIn page, as it lists his leaving Porsche in March of this year to join "A Technology Company" in the "San Francisco Bay Area", which isn't exactly untrue. In any case, they've hired a true talent.
