The 997 Turbo debuted in February 2006 at the Geneva Motor Show. It featured a new front bumper with LED turn signal strips integrated in the air intakes; the fog lamps were moved to the corners of the bumpers. Large air vents fore and aft of the rear wheels provide other obvious visual cues of the Turbo model. The turbo utilises the wide body shell of the AWD models, giving it a more aggressive stance than the base 911 models. Also featured was a retractable rear wing, as used on the 996 Turbo along with air vents on the rear quarter panels in order for effective engine cooling. The 997 Turbo is lighter than its predecessor due to the extensive use of aluminium in key elements of the car.
