At this stage, we don't expect the new 911 to enter showrooms before 2018. The vehicle pictured here is a very early development mule, which uses the body of the current car as its basis.
Thanks to the wheel arch extensions fitted to this prototype, it's fairly safe to assume that the next-generation 911 will feature a wider track at the rear.
There are also revisions to the car's intake and exhaust vents, but it doesn't look like the new 911's dimensions will differ too greatly from today's car.
Even though we have no inside track on the design of the next-gen 911, it's probably safe to say that it will feature a gentle evolution of what has preceded it.
Porsche is currently in the process of rolling out its "991.2" facelift for the current-generation 911. So far, it has unveiled the Carrera, Carrera S, Carrera 4 and Carrera 4S models, as well as their convertible and Targa siblings.
In a first for the iconic sports car range, all these new regular-range models feature turbocharged engines. In this case, they all use different versions of the company's 3.0-litre turbocharged horizontally opposed six-cylinder engine.
Given that emissions and greenhouse gas regulations are only going to get stricter, turbocharging looks like it will play an integral part of the 911 story from this point on.
The company will soon launch harder core variants of the current-generation 911 family, including a new GT3, as well as a naturally aspirated manual transmission car, likely to be dubbed the 911 R.
