Audi's new urban-car prototype, the A1 Metroproject Quattro Concept, introduces a new concept in car-phone interactions. Acting as remote version of Audi's in-car Audi MMI interface, a handset goes with the concept car that acts as combination key fob, navigation unit, audio and video player and interface for the car's systems. Using both wi-fi and 3G UMTS communications, it can perform such aftermarket-like miracles as remote starting (with climate controls), image capture via on-board digicams — a kind of security-camera system — and act as receiver for the car's location-tracking device (yep, LoJack). It's just what we've always wanted. Now to get Gizmodo to come up with some kind of i-Phone hack. [via Motor Authority]
