Porsche has unveiled the 2012 911 (991) at the Frankfurt Motor Show.

Built to usher in a new era of performance, the model has an evolutionary design that is instantly recognizable. Déjà vu aside, the car has a wider track and a wheelbase that has been stretched 100mm (3.9 inches).

Inside, the cabin is significantly improved with higher quality materials and a design that mimics the Panamera. Notable highlights include a sloping center console, additional trim and updated switchgear.

The entry-level Carrera has a 350 PS (257 kW / 345 hp) 3.4-liter engine which enables it to accelerate from 0-60 mph in 4.4 seconds (4.2 seconds with the optional Sport Chrono Package) and hit a top speed of 179 mph (288 km/h).

On the other hand, the Carrera S features a 3.8-liter engine with 400 PS (294 kW / 394 hp). It dashes from 0-60 mph in 4.1 seconds (3.9 seconds with the SC package) and tops out at 188 mph (302 km/h).

The 2012 Porsche 911 will go on sale later this year and pricing starts at €88,038 (£71,449 / $82,100).ABONNIEREN /subscription_center?add_user=motorvisioncom FACEBOOK /motorvision Google+ ...
