50 years ago, the first 911 made its debut. 10 years after that, the 911 Turbo prototype was shown for the first time. In 2013, the 50th and 40th anniversary years of the 911 and 911 Turbo respectively, Porsche has just unveiled the most advanced, all-new, 991-generation, 911 Turbo and Turbo S. Boasting all-wheel drive, active rear-wheel steering, adaptive aerodynamics, full-LED headlights and signature turbocharged flat-six engine, Porsche say the 911 Turbo has reached its pinnacle.
