ALL 911s TURBO!!!
According to Andrew Frankel at MOTORSPORT when he interviewed Wolfgang Hatz of Porsche motorsports.
Porsche's future plans - Road - Motor Sport Magazine
"911: This will be a game-changing year for Porsche’s most iconic nameplate and the first clue to it will come at the Geneva Motor Show in March when Porsche will reveal the delayed RS version of the GT3. Hatz says it is a far more extreme car than its predecessor and that, contrary to speculation, will most definitely be normally aspirated. But, and this is big news, it will have a brand new engine related to neither the old race-derived engines used in previous GT3 and GT2 models, nor the motor in the current GT3. Would Porsche design a whole new engine for one niche product? It would not. In fact this is just its first application: this September it will go into every 911 in turbocharged form.
You read that right: by this autumn, every single non-Motorsport 911 from the cheapest Carrera upwards will be turbocharged."
