The new 991 generation of Porsche 911, unveiled at the 2011 IAA, is set to last 14 years.

Car Magazine revealed the new model will have two seven-year lifecycles, which means the same styling will remain in production until 2025, but every few years it gets refreshed with a few very subtle tweaks and revisions.

The British mag also revealed when we can expect the other variants of the 991 to arrive. The Carrera and Carrera S will be launched later in the year. they will be followed by the cabriolet versions early next year, but for the four-wheel-drive versions, Carrera 4 and Carrera 4S, you have wait until December 2012.

That means the 991 Turbo won’t be launched any time sooner than 2013. It will be followed by the GT3, Targa and Speedster models, the latter in early 2014, and some time after that we will be getting the first hybrid Porsche 911.

We don’t mind to see this 911 for the next 14 years. We like it. If you don’t, tough luck!
