New Porsche 911 Carrera 4S (turbo) vs. Old Carrera 4 GTS, 0-155 MPH Comparison

Zuffenhausen knows this all too well, which is why the German engineers have thrown in a hefty performance premium with the 991.2 mid-cycle boost. So how does the extra power and, more importantly, the extra twist translate into real-world performance?

The video at the bottom of the page, which comes from Motorsport Magazine, offers a sharp answer to that question, at least when it comes to straight line adventures.

The clip shows an acceleration comparison involving a 2016 911 Carrera 4S and the old 911 Carrera 4 GTS - the GTS was chosen over the S to make the most out of the atmospheric models' potential.

We'll take the time to remind you that the 991.2 Carrera 4S is motivated by a 2,981cc flat-six, which delivers 420 hp and 369 lb-ft (500 Nm) of torque, while tipping the scales at 3,329 lbs (1,510 kg).

As for the now-old Carrera 4 GTS, the 3.8-liter boxer unit at its back produces 430 hp and a peak torque of 324.5 lb-ft (440 Nm), while the sportscar weighs in at 3,285 lbs (1,490 kg).

And there's another difference between the two, one that makes itself noticed whenever the all-wheel-drive needs to be put to serious work. You see, the 991.2 "4" models feature electro-hydraulic control for their AWD, a move that was previously reserved for the Turbo and Turbo S.

And since we've had enough numbers, it's time to let the piece of footage below do its job.

P.S.: Turbo lag questions aside, the "facelift" brings a downside in terms of aural pleasures and, when it comes to how great the soundtrack difference between the two is, we're asking you to be the judge.
