The 911 Turbo Cabriolet (997.1), added for 2008, is the open-top version of the wide-body twin-turbo 911. It shares the Turbo's 3.6-liter twin-turbo "Mezger" flat-six with VTG turbos, all-wheel drive and six-speed manual or five-speed Tiptronic S, with a power fabric top in place of the coupe roof.

As a Mezger car it does NOT carry the Carrera M96/M97's IMS-bearing or bore-scoring risk. Inspect the coolant pipes and check for the P0021 cam-timing fault, and confirm any tuning was done properly, but the Carrera engine lottery does not apply here.
