The world’s worst-kept secret is now official – the new Porsche 911 Carrera range is now turbocharged.

As first reported by MOTOR back in July, the need decrease fuel consumption and emissions has led Porsche to introduce a turbocharged engine to its 911 Carrera range for the first time.

A 3.0-litre twin-turbo flat-six in two states of tune replaces both the previous 3.4-litre and 3.8-litre naturally-aspirated units that powered the Carrera and Carrera S respectively.

Speed also increases, the Carrera dispatching 0-100km/h in 4.2sec (an improvement of 0.2sec) when equipped with the seven-speed PDK gearbox, while the Carrera S dips under the magic four-second mark for the first time, claimed to hit 100km/h in just 3.9sec.

As you’d hope given it was the reason for the change, fuel consumption has also improved markedly, a PDK-equipped Carrera claiming just 7.4L/100km on the combined cycle, and the more powerful Carrera S just 0.3L/100km more.

In fine Porsche tradition, exterior tweaks have been limited to new headlights and taillights, redesigned door handles and a new louvred engine cover.

Inside the changes have been greater, with the latest Porsche Communication Management offering a smartphone-like touch-and-swipe interface.
