Following last week's online reveal, the facelifted Porsche 911 Carrera S has made its debut in the metal at Frankfurt Motor Show.

You have to pretty much be a Porsche aficionado to notice the styling changes on this 991.2 Carrera S as the revisions to the headlights, wheels, door handles and bumpers are very subtle. Perhaps the most noticeable change is the new engine cover featuring vertical louvers while on the inside there's a revised PCM 7-inch system, new smartphone tray in the center armrest along with other minor tweaks.

More important changes have occurred underneath the skin as the Carrera S is no longer naturally aspirated since Porsche has decided to ditch the old engine and replace it with a new twin-turbo six-cylinder 3.0-liter which develops 420 PS (309 kW) and 500 Nm (368 lb-ft) of torque, making it 20 PS (14 kW) and 60 Nm (44 lb-ft) more powerful than its predecessor. The base Carrera uses the same engine but with 370 PS (272 kW) and 450 Nm (331 lb-ft), also a 20 PS & 60 Nm improvement.

In terms of performance, the PDK-equipped 911 Carrera S with the Sport Chrono Package runs the 0-62 mph (0-100 km/h) sprint in 3.9 seconds and tops out at 191 mph (308 km/h).

Other changes include a standard post-collision braking system, optional adaptive cruise control (with coasting), optional lane change assist and optional automatic speed control system.

Sales of the facelifted 911 Carrera range will begin in December at home in Germany from €96,605 for the base model.
