The 2016 Porsche 911 line-up has gained further momentum with the unveiling of the facelifted Carrera 4 and Carrera 4S in both coupé and cabriolet body styles, as well as the Targa 4 and Targa 4S.

On the outside, the new models feature redesigned headlights and front bumpers with active air ducts that open and close automatically to channel air to the front-mounted radiators. There are also larger exterior mirror housings mounted on the doors and new door handles. At the rear, there's a new bumper with redesigned tail-lights and an all-new air vent on top of the rear-mounted engine. Flared wheel arches and a horizontal light bar connecting the tail-lights further differentiate the four-wheel-drive versions from the rear-wheel-drive editions.

Inside, the new models adapt the same upgrades as the rear-wheel-drive variants such as Porsche’s Communication Management (PCM) multimedia system, a larger 7.0-inch touchscreen that supports both Apple CarPlay and Android Auto connectivity and satellite navigation as standard.

The cars now get the new twin-turbocharged 3.0-litre six-cylinder engine, recently seen in the latest 911 Carrera and Carrera S. The new engine bumps up the figures with the cars producing 365bhp and 45.90 kgm of torque. A similar upgrade is seen on the Carerra 4S and Targa 4S with the new turbocharged engine making 414bhp and 51.01 kgm of torque. Gearbox choices remain the same as before, with a seven-speed manual offered alongside a seven-speed PDK dual-clutch unit. A new option on the 911 Carrera 4S is a four-wheel steer system, similar to that used by the 911 Turbo and GT3. On models running the optional Sport Chrono package and seven-speed PDK dual-clutch gearbox, an additional Sport Response button is fitted for maximum acceleration.

These new versions are set to make their public debut at the Los Angeles motor show next month. Deliveries are expected to start early next year.
