Audi is preparing a reskin of its breakthrough A4 and will use styling cues from its A6 as inspiration. This computer-enhanced photo is based on insider descriptions and sightings of prototypes. The A4's overall look is expected to be more angular and chiseled than today's model. With its deeper front chin spoiler and angular cornering lamps, the nose of the A4 will emphasize its relationship to the new siblings, the A6 and the TT. The A4's greenhouse will be more streamlined than the A6.
