It’s been known for some time now that Porsche is working on a refreshed 911, as we’ve seen prototypes lapping the Nurburgring and on the streets of Europe. With this impending refresh come rumors about the machinery that lies under its rear bonnet. Car Magazine claims to know exactly what’s under the hood, and it may make some Porsche fans quite angry.

According to the report from Car Magazine, the days of the sweet sounding, naturally aspirated, flat-six engine in the 911 Carrera and Carrera S are numbered, as the automaker is moving to turbocharged engines. Among the collective groans of Porsche fans are a few cheers, as these force-fed engines will result in nice power gains in each version.

Car Magazine reports that the 911 Carrera S’ engine will be downsized from a 3.4-liter to a 2.9-liter flat-six, but the turbocharger will swell its output to 400 horses and 400 pound-feet of twist. That amounts to a 50-horsepower and 113 pound-feet gain over the current Carrera. The Carrera S will reportedly keep its 3.8-liter engine, but the turbo will push its power to 530 horsepower and 520 pound-feet. That’s a gain of 100 horsepower and 195 pound-feet of torque.

The most interesting fact here is that if these reports prove to be true, the 911 Carrera S will trump the current 911 Turbo’s 520 horses and infringe upon the Turbo S’ 560 ponies. This means that these models will likely get a power bump in the 991.2 generation too, which adds some validity to the rumors of hybridized 911s.

Now, before the majority of you 911 fans start heading to Stuttgart with pitchforks in your hands, not every 911 will be turbocharged in the 991.2 generation. The GT3 will reportedly remain naturally aspirated.

We’ll bring you more details as they come out, so keep it locked here for all the latest on the refreshed Porsche 911.
