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 41 kg lighter than its predecessor due to the extensive use of aluminium in key elements of the car. The engine was based on the 911 GT1's design and is rated at 473 bhp and 457 lb⋅ft with 502 lb⋅ft 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 utilisation of the torque produced by the engine.

The engine uses two BorgWarner VTG turbochargers, a first for a Porsche production car. The turbochargers are fitted with a two-stage resonance intake 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. The optional Sport Chrono package allows the 911 Turbo to overboost for ten seconds (1.0 bar to 1.2 bar), increasing peak torque over a narrow RPM range.
