The Porsche 991 is the internal designation for the seventh generation Porsche 911 which was unveiled at the 2011 Frankfurt Motor Show on 15 September as the replacement for the 997. An initial release of photos and information was revealed by Porsche on 23 August 2011.

The current direct injection 3.8-litre flat-six engine from the Carrera S remains, with power increasing to 400 PS (294 kW; 395 hp). The Carrera engine is a 3.4-litre, producing 350 PS (257 kW; 345 hp). The car features an optional stop/start system and also electro-mechanical power steering. The car also features a new seven-speed manual gearbox, a first for a production car, along with the seven-speed PDK dual clutch transmission which was available in the 997.

Compared to the outgoing 997, the 991 wheelbase has increased by 100 mm (3.9 in) to 2,450 millimetres (96.5 in), with the overall length up by 70 mm (2.8 in) to 4,490 millimetres (176.8 in). A new transaxle was developed so that the rear wheels could be moved 3 inches backward in relation to the position of the engine, which significantly improves the weight distribution and cornering performance of the new 911. Due to the use of high-strength steels, aluminium and some composites the weight has been reduced by 45 kg (99.2 lb) to 1,470 kilograms (3,250 lb).

Images of the 991 were widely published on the internet on 18 August 2011, prior to the car's official debut. The photos revealed Porsche had taken an evolutionary design step, in keeping with the previous generation 997 and 996.
