The model code of the 911 produced from 2011 to 2019 was 991.
The 991 was the seventh generation of the Porsche 911, replacing the 997. Porsche unveiled it at the Frankfurt Motor Show on 15 September 2011, and production ended on 20 December 2019. It was an important redesign because Porsche described it as only the third entirely new 911 platform since the original model debuted in 1963.
The generation included numerous body styles and variants, including Carrera coupés and convertibles, the Targa, Turbo, GT3, GT3 RS, GT2 RS and Speedster. Early 991 models used naturally aspirated flat-six engines, while later Carrera versions adopted turbocharging. The successor was the 992, which explains a common mix-up: 992 is the generation that followed the 991, not the answer for the 2011–2019 production run.
Porsche produced 233,540 examples of the 991 generation. The designation is a factory model code, while “911” is the model name familiar to buyers.
