The new 2011 Porsche 911 (991 model code) will be a ground-up transformation over the existing 997 model. It will be up to 50kg lighter, feature all-new suspension geometry and the rear axle will be pushed back by around 75mm. This will offer more interior space, but will also afford a more optimum mounting position for the engine. Better handling and increased overall stability the result.
Improved aerodynamics, stop-start technology and a brake regeneration system will help improve efficiency by around 10%, despite the inevitable (albeit modest) power gains. It has been reported the 991 911 will feature a 7-speed manual transmission, which has been derived from the PDK unit.
Inside, the 991 will draw its look from the Panamera, including easier to read dials and a wider centre console. Overall, the new 911 will be a more comfortable place to be.
