The Porsche 991 is the internal designation for the seventh generation of the Porsche 911 sports car, which was unveiled at the 2011 Frankfurt Motor Show on 15 September as the replacement for the 997. The 991 is an entirely new platform, only the third since the original 911 launched in 1963 (the 996 of 1999 was the second new platform).
Compared to the 997, the 991 is slightly larger, with the wheelbase increased by 100 mm (3.9 in) to 2,450 mm (96.5 in), and the overall length up by 70 mm (2.8 in) to 4,490 mm (176.8 in). A new transaxle was developed so that the rear wheels could be moved 76 mm (3 in) backward in relation to the position of the engine, which significantly improves the weight distribution and cornering performance of the car.
Due to the use of high-strength steel, aluminium and some composites, the weight was reduced to 1,380 kg (3,042 lb) for the manual Carrera, rising to 1,605 kg (3,538 lb) for the all wheel drive Turbo model with PDK transmission (Porsche Doppelkupplung). PDK is available as an option for all 911 Carrera models as a 7-speed transmission, featuring manual and automatic modes. Gears 1 to 6 have a sports ratio and top speed is reached in 6th gear. 7th gear has a long ratio and helps to reduce fuel consumption by keeping engine revs low. The auto start/stop function is standard on all variants of the 911 Carrera. Introduced at the 2011 Geneva Motor Show, the Carrera is equipped with a 3.4 litre boxer engine with direct fuel injection generating a maximum power output of 350 PS (257 kW; 345 hp) at 7,400 rpm and 390 N⋅m (288 lb⋅ft) of torque at 5,600 rpm.
This stunning example was originally supplied by Porsche Centre Guildford in September 2012, since then the vehicle has been serviced by Porsche at 7353, 9533 and 12655 miles and will be supplied with a factory build card, both remote keys and a full set of hand books to include the service folder.
