I don't see the 918 or 919
I don't see the 918 or 919 engines as suitable candidates for the next gen 911. Why change from the flat six which is already pretty fuel efficient? Just adding electric motors will bring the CO2 and fuel consumption down enough. What I am curious about is if they will keep the current AWD system or go with an electric motor up front in addition to one bolted to the PDK in the rear. Another question is what 911 model they will go hybrid with first - the turbo?
