The Porsche 991 marked a major step forward for the 911, introducing an all-new platform that was longer, wider, lighter, and more refined than the 997 it replaced. Produced from 2012 to 2019, the generation spanned everything from the Carrera and Carrera S through to the Turbo, GT3, GT2 RS, Speedster, R, T, and several special editions. The 991 is commonly divided into the naturally aspirated 991.1 and the turbocharged 991.2, with the latter introducing turbocharged engines across the Carrera range for the first time. Today, the 991 is valued for combining modern performance and technology with much of the character that enthusiasts associate with traditional 911s. The guide below shows every major 991 variant, including engine changes, drivetrains, power outputs, and special editions.
