The 24/7 Supercar: Just your average, everyday, 480HP, AWD missile that gives a lot and asks little in return.
The 997 Turbo debuted in February 2006 Geneva Motor Show. It featured a new front bumper with LED turn signals 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 utilizes the wide body shell of all the AWD models, giving it a more aggressive stance than the base of 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 engine was based on the 911GT1's design and is rated 480bhp and 457 ft-lbs and 502 ft-lbs at overboost of torque. The torque is managed by Porsche Traction Management (PTM) system in conjunction with the Porsche Stability Management (PSM) system in order for a safer utilization of the torque produced by the engine.
The engine uses two Borg Warner VTG turbochargers, a first for a Porsche production car. The turbochargers are fitted with a two-stage system. The Variable Turbine Geometry incorporates guide vanes on the turbine wheel that change their angle of attack with exhaust speed, reducing turbo lag at low speeds while opening up to prevent excessive back pressure at high RPM.
