No but there are windings somewhere in the hub and a cable back to charge the system. Each hub acting as a mini alternators from what I remember being told.

OK, so a quantum leap of sorts, I suppose - but hardly a groundbreaking innovation. And if their marketing can be so misleading on that issue, it makes me dubious about everything else...

It's the same as the Prius does only theirs are designed to be used as motors as well as alternators. Essentially the same thing anyway, it's just that BMW don't provide drive from them.
