From naturally aspirated to turbo

As I walked past the Joe Duffy Porsche Centre Dublin I saw two 991 Carrera S parked next to each other. A first generation in dark blue a second generation in white. Isn’t that the perfect occasion to compare the two?!


The Porsche 991 generation was introduced in late 2011 replacing the hugely successful 997 generation. This particular dark blue metallic Carrera S has a traditional naturally aspirated 3.8l flat 6 engine, producing 400 hp. The facelifted 991 Carrera S, officially called 2nd generation 991, was introduced in late 2015 and brought a major revolution to the Carrera family: turbocharger. Yes, indeed, this Carrera S is carrying a turbo charged 3l Flat 6 engine, producing 420 hp.
The external differences
The front bumper and air intakes have been re-designed. The LED daytime running lights are much slimmer on the second generation. Even though the headlight units are identical from the exterior, they have also been revised and are now featuring four-point daytime running lights. In the back, we can spot four major changes compared to the previous version:
- The general shape of the rear bumper
- The shape and centered position of the exhaust pipes
- The three dimensional shape of the taillights
- And the engine cover grill or vent which now shows 24 vertical lines instead of the previous three horizontal blades
When it comes to the wheels and chassis, the Sport version with the red brake calipers is almost identical. Only the back tires are half an inch larger on the newer model.


A zest of 918 in the cabin
Inside, only changes have been made where it really mattered: the steering wheel has been replaced with a 918-inspired wheel, eliminating once and for all the counter-intuitive gear changing buttons on the standard wheel. Moreover, the infotainment system has also been upgraded.
