Your car is about to be a software platform, subscriptions and all

Yes, the Porsche Taycan is flying out of dealerships. And yes, it charges rapidly. But you may not have heard much about the most vanguard feature on Stuttgart's newest electric vehicle.

Taking a cue from Tesla, Porsche is finally treating its 5,000-pound computer like the SAS platform that it is.
