The Porsche 991 was unveiled at the Frankfurt Motor Show on 15th September 2011 as the replacement for Porsche 997.

The design of the Porsche 991
The Porsche 991 was slightly larger with an increased wheelbase by 3.9 inches and an increased overall length by 2.8 inches.
A new transaxle was developed so that the rear wheels could be moved 3 inches backward in relation to the position of the engine. This was done to improve the weight distribution and cornering performance of the car.
To build the car, high-strength steel, aluminum, and composite materials were used to reduce the curb weight of the car as much as possible.

The Porsche Dopplekupplung (PDK) transmission was available as an option for all Porsche 991 models as a seven-speed transmission unit. This unit featured both manual and automatic modes. It is basically a combination of two gearboxes together into a single unit and therefore required two clutches. This unit was produced by ZF Friedrichshafen, a reputed German automotive products manufacturer.
Gear one to six features close ratio and the top speed is reached in the sixth. Seventh gear has a long ratio and keeps the engine revs lower to reduce fuel consumption.
