The highly anticipated Audi A4 (B9) has been spied undergoing final testing without any sort of camouflage.

The highly anticipated Audi A4 (B9) has been spied undergoing final testing without any sort of camouflage.

As expected, the all-new compact sedan from Ingolstadt has taken the evolutionary route in terms of design as it's not that much different than the outgoing model. However, it does appear to look sharper and adopts sleek lighting clusters while the third side windows seem to be a bit smaller. The rear doors appear to be slightly longer which indicates Audi's engineers have stretched the wheelbase to boost legroom for rear passengers.

The black prototype likely has full LED headlights and taillights and rides on a fresh set of alloy wheels while the side mirrors have been positioned lower on the doors and have a more curved shape. There seems to be a metallic/chrome line starting from the upper left corner of the headlights and continuing on the car's side and also at the back above the taillights. There's a thicker bar on the lower area of the doors while the reverse taillights could be those tiny white rectangles part of the taillight cluster on the trunk lid.

Photos of the interior cabin are not available in this set, but in one of the attached images you will notice the new Audi A4 will get the free-standing display as seen in other recent models with the four ring logo.

Since Audi didn't even bother camouflaging this prototype, chances are an official reveal will occur very soon. A public debut is set for September at the Frankfurt Motor Show, with sales to begin shortly thereafter.
