Here are the latest and first spyshots of the Turbo Cabriolet with the roof down showing more details of the forced induction family of the new 911.

The latest generation ‘991’ has already been released in normally aspirated engines and this will follow on from the legendary 911 Turbo.

The new 911 Turbo Cabriolet should come onto the market as a 2013 model complete with a twin-turbocharged flat-six engine, wide rear arches.

An advanced tri-turbo setup has been reported as a possibility, with the addition of the third turbocharger aimed at improving low-end response but this could be the first practical application of KERS in a road going Porsche.
