It had to happen sooner or later, right? The 991-generation 2016 Porsche 911 Carrera and Carrera S facelift models have been revealed with turbocharged engines and minor physical alterations ahead of the pair’s physical debut at the 2015 Frankfurt Motor Show.

As expected, exterior changes are about as minute as it gets with the front end receiving new headlights with four-point LED daytime running lights, new wheel designs, integrated door handle recesses, redesigned taillights and most noticeably, a reworked rear deck lid with vertical louvres.

The most significant upgrade is to be found beneath the skin, as mentioned. For the first time, the Carrera and Carrera S will be equipped with a biturbo 3.0 litre flat-six engine. In the entry-level Carrera, said mill pumps out a total of 370 PS and 450 Nm of torque. The same engine in the Carrera S puts out 420 PS and 500 Nm thanks to a “a model-specific exhaust system and different tune for the engine management system.”

Straight-line performance figures include a 0-100 km/h time of just 4.2 seconds and 3.9 seconds – top speed is rated at 295 km/h and 308 km/h for the Carrera and Carrera S, respectively. Said figures were achieved with the inclusion of Porsche’s seven-speed PDK dual-clutch transmission and Sport Chrono Package. Rear-wheel steering is optional while a seven-speed manual transmission is standard in both models.

Porsche Active Suspension Management (PASM) is also featured as standard. With Sport Chrono Package added, the new 911 models will also feature a rotary switch within the steering wheel (a feature seen on the 918 Spyder) that offers drivers a total of four driving modes – Normal, Sport, Sport Plus, and Individual. Porsche claims that all these changes have resulted in a Nurburgring lap time of just 7:30.

Inside, upgrades are limited to the aforementioned revised steering wheel with a rotary switch and a new Porsche Communication Management infotainment system. The latter features a seven-inch touchscreen display, Apple CarPlay compatibility and a navigation platform with Google Earth and Google Streetview integration. A smartphone tray with wireless charging is to be found within the armrest.
