The Porsche 911 (997) Turbo launched in 2006 with a 3.6-liter twin-turbocharged flat-six producing 480 hp, paired with a 6-speed manual or Tiptronic S gearbox. All-wheel drive and Porsche Active Suspension Management (PASM) made it one of the most capable and usable supercars of its era. The 997.2 Turbo (2010) later bumped power to 500 hp. Current market values typically range from $75,000–$110,000 for well-maintained examples.
