A developmental version of the next-generation Porsche 911 has been spotted on and around the Nurburgring Nordschleife.
With its pumped guards, especially the altered rear fenders, it's clear that new 911 will have a wider track than today's vehicle. The body of this development mule doesn't show any exterior signs of lengthening, so it seems that the 911 will feature a wheelbase that's roughly the same as today's car.
No technical details have been confirmed by the company regarding the new 911, but it's safe to assume that regular models will be powered by updated versions of the 3.0-litre turbocharged horizontally opposed six-cylinder engines, which made their debut with the '991.2' facelift.
It's possible that more hardcore variants of the new 911 will continue with a naturally aspirated boxer-six.
Although there has been speculation about the possibility of hybrid 911, Michael Steiner, Porsche's head of research and development, told CarAdvice two months ago that such a model isn't a priority for the company.
Instead the company will focus its green car efforts on bringing the all-electric Mission E electric sedan to market.
The next-generation Porsche 911 is expected to make its debut in 2018, so we can expect to see prototypes wearing the new car's body soonish.
