Look for debut at Detroit or Geneva in 2006.  The exterior front end sheet metal gets a complete makeover in order to comply with new EU pedestrian crash laws.  In these photos peering through the front bumper outer grille openings appears to be some sort of vertical signal lamp although the front bumper fascia seems to be a mix between the Turbo and S model.  Partially covered, the headlamps get a new sleek shape and the rear tailamps get slightly shortened.  The rear bumper fascia gets a restyling with cleaner integration of the exhaust pipes.  Photos show both dual tip and single tip exhaust.  Also expect the base 3.2 liter V6 to get upgraded with the new narrow-angle 280hp 3.6L Passat VR6 engine.
