When Porsche introduced the 911, no one could have imagined the impact the model would have on the automotive world. The rear engined sports car has seen numerous generations and variants, each with distinct engine and drivetrain configurations. In production since 1965, the 911 has become synonymous not just with Porsche, but sports cars in general. The 911's design has evolved over the years, yet the general styling of the car has remained unchanged, with its trademark teardrop shape noticeable through all variants. With a production run of over 50 years, the 911 counts some of the motoring world's most well known models amongst its history. Cars such as the Carrera RS, the 930 Turbo, and the 993 GT2 feature amongst some of the storied variants that mark the history of the 911.
