You knew this was coming.
The fact that a Porsche 911 hybrid was on the way has been obvious for some time. The hybrid technology developed for the 918 Spyder as well as the 919 LMP1 Le Mans prototype racer was bound to trickle down to the rest of the model line at some point. We've even seen a hybrid 911 before, the 911 GT3 R Hybrid concept, all the way back in 2010. So it should come as no surprise that Porsche R&D chief Wolfgang Hatz has said we should expect to see one by the end of the decade.
Turbocharging, as you may already be aware, will be coming to the entire 911 range within the next couple of years, ushered in by the 991's midcycle refresh. But when the next generation debuts, so will the production hybrid 911. The system might not be available on the entire 911 range to start with though. It is expected to be introduced first with the 911 Turbo, or whatever that ends up being called once all of them are turbocharged. Lower-end models will surely get it soon enough, but we don't yet know anything about how hybridization will spread once introduced.
