Don�t be fooled by the �concept� label � the Audi Sportback is going to happen. It�ll arrive next year � most likely named the A7 � and though the roof will be touch higher and the wheelarches a touch less flared, it�ll be more or less as you see here, which is all good. So what is it? The A7/Sportback is Audi�s take on the four-door coupe formula � think of it as a competitor for the Merc CLS and Jaguar XF � so it�s a big car: the same size as the A6, in fact. There are plenty of clues to Audi�s next-generation styling cues, too � take a look at those narrow-eyed, tapered headlights (all LEDs, of course) and that chamfered single-frame grille, which looks very similar to the front of the A1 show car we saw in Paris. The car shown at the Detroit show is powered by a very realistic-sounding three-litre V6 turbodiesel putting out 225bhp and 406lb ft of torque, but expect the A7 to get Audi�s full range of big drivetrains � and quattro, of course � when it reaches production. How about a V10 S7, then? Yes please. Yes please indeed.
