Porsche 911 (991)

The Porsche 991 is 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 was an entirely new platform, only the third since the original 911 launched in 1963 (the 996 of 1999 was the second new platform). Production of the 991 generation ended on 20 December 2019, with 233,540 units produced.

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 if equipped with the PDK transmission (Porsche Doppelkupplung). PDK is available as an option for all 911 Carrera and 911 Turbo (991.1 Non S) 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 PDK is essentially two gearboxes merged into a single unit and thus requires two clutches. For all 991 models, the PDK is produced by ZF Friedrichshafen. 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. The Carrera S has a 3.8-litre engine generating a maximum power output of 400 PS (294 kW; 395 hp) at 7,400 rpm and 440 N⋅m (325 lb⋅ft) of torque at 5,600 rpm.

The convertible variant of the 991 was announced in both Carrera and Carrera S versions at the LA Motor Show in November 2011.

In September 2012, at the Paris Motor Show, the all-wheel-drive variants, the Carrera 4 and 4S, were added to the 991 lineup.

In May 2012, Porsche revealed the Carrera S Club Coupe. The main difference was a power increase (from 400 to 430 hp) and a ducktail spoiler. It was only offered in Brewster Green, had 5-spoke silver over dark green rims, yellow PCCB brakes, chrome window trim and Club Coupe lettering on sides. Thirteen cars were made worldwide.

Also in 2013, Porsche showed the Carrera 4S Exclusive Edition. It features a power increase, ducktail spoiler and dark grey exterior with silver over black 5-spoke rims. It was limited to 5 units only for UK.
