No more naturally aspirated 911s?

No more naturally aspirated 911s?
I have heard nothing about this until now: http://www.autoblog.com/2015/01/23/p...o-save-gt3-rs/
Supposedly, all 911s will come with turbo engines from now on (all but the 911 GT3 and GT3RS).

That's the first article I've read that suggests the 911S will get a turbo 3.8L with the same power as the current 911 Turbo. That's too big of a jump (typically) for Porsche and I can't see them going from 430 hp to 520 hp in one fell swoop like that.
Sticking to 3.8L and adding turbo doesn't seem like it would do anything for emissions or mileage. Not sure that it makes any sense, to me.
I'm guessing similar power, more torque and smaller displacement all around (for the 911 and 911S). The Turbo model will obviously stay turbo.

You may have missed the boat on that example. There are dozens of examples of companies swapping high displacement NA engines for low displacement FI engines but the Corvette is not one of them. The engine is the same size as the last generation (6.2) and the same size as the ZR1. I don't see how it is an example of going FI to help with emissions. GM utilized several other technologies (cyl deactivation, direct injection, additional gears) for that but held off on using a smaller engine...

Exactly - turbos don't help emissions if you're using the same displacement motor. Usually they downsize the motor displacement, add a turbo and thus get less emissions (at low revs) than a comparable larger-displacement normally aspirated engine.

You guys are right, but the new Z06, as I understand it, is supercharged because for a given horsepower goal, a supercharged kind-of-big engine is better emissions-wise than a naturally aspirated really big engine.

Yeah, I'm skeptical about the whole thing.

Possibly, except they might go with a smaller power plant to start off.
The Macan will be the first vehicle line to execute this.
Regular Macan is a 3.0L turbo.
Macan S is a 3.8L turbo (not sure if twin turbo).
There is no NA variant of the Macan.

Probably was cheaper power too. Supercharging vs up-sizing the displacement by 30-35%. I know the previous z06 was upsized, buy only by 13%.
