Porsche 911 (991)
The Porsche 911 (991) is the seventh generation of the Porsche 911 sports car produced by Porsche from 2011 onwards as the successor to the 997. It is an entirely new platform, the third since the original 911 in 1963, following the 996 of 1999. In 2018, the 991's successor, the 992, was unveiled and entered production in 2019.
NOTE: This article will only cover models that are featured in the Forza series.
Overview[edit | edit source]
In comparison to the 997, the 991 is slightly larger, with a longer wheelbase of 2,450 mm (96.5 in) and an overall length of 4,490 mm (176.8 in).[1] Porsche developed a new transaxle so that the rear wheels could be moved back 76 mm (3 in) in relation to the engine's position, significantly improving the car's weight distribution and handling.[2][3]
Due to the use of high-strength steel, aluminium and some composites, the weight was reduced to 3,042 lb (1,380 kg) for the manual Carrera, rising to 3,538 lb (1,605 kg) 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. All gears from first to sixth have a sports ratio and top speed is reached in sixth gear. Seventh 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 911 Carrera variants.
