Lichte also confirmed that the Q4 E-Tron show car's Digital Signature Lights -- the reconfigurable LED running lights -- will carry over to production. But unlike the blocky checker pattern of the concept car, the production version will use two rows of thin, vertical strips, with a solid LED light running horizontally between them. It's hard to tell, but the Q4's low- and high-beam headlights are actually housed below the LED light cluster.

What's more, Lichte confirmed the production Q4 will have Audi's new augmented reality head-up display, which can project things like turn-by-turn direction arrows far out into the driver's field of view. Mercedes-Benz, for example, currently incorporates this sort of AR tech in its MBUX infotainment display, but Audi will actually be able to project it onto the windshield.
