Porsche 911 going all-turbo this year save for GT3 and GT3 RS
The engine in the coming Porsche 911 GT3 RS will be the heart of the turbocharged engines going into the 2016 911 range coming later this year. It will remain naturally-aspirated in the GT3 models, but get boosted help for every model below those. Elsewhere, the next Boxster and Cayman will get turbocharged four-cylinders, and a V8-powered mid-range Porsche supercar is still in the works.
