Finally, Audi has a new twist on this design: regenerative braking while turning. Since the inside wheel often runs slower than the outer wheels in a curve, that inner wheel with a motor mounted can be used to regenerate electricity as it slows to control the turn. That gives both an unprecedented amount of control in the turn, but also a definite increase in efficiency.
This is demonstrated in a new short promotional video from Audi:
So along with edge-cutting design, the Audi NSX will have some industry-leading technology happening under the hood as well. This may become the most-anticipated new sports car we've seen for some time.
