Porsche 911 Carrera 4S

The Carrera 4S Coupe is among six new four-wheel drive 911 models rolling out into the UK.

As with its recently introduced rear-wheel-drive siblings, the 911 Carrera 4S receives a series of subtle styling updates as part of a reasonably comprehensive mid-life facelift. Included is a redesigned front bumper sporting active air ducts that open and close to channel air to the front-mounted radiators dependent on throttle load, revised headlights with altered internal graphics, larger exterior mirror housings and new door handles.

It also gets reworked air vents atop the engine lid at the rear for greater cooling efficiency, modified taillights sporting more heavily structured three-dimensional lenses, and a revised rear bumper with air vents either side to channel hot air away from the engine.

Wider rear wheelarches and a horizontal light band set between the taillights continue to distinguish the various four-wheel-drive models from other new 911 models.

More significant than the styling tweaks, though, is the adoption of an all-new engine. Taking the place of the old naturally aspirated 3.8-litre flat-six unit is an all-new twin-turbocharged 3.0-litre horizontally opposed six-cylinder engine: the ‘9A2’, as it is known within Zuffenhausen circles. It endows the new 911 Carrera 4S with an added 20bhp and 45lb ft, delivering 414bhp at 6500rpm and 369lb ft on a band of revs from 1700 all the way through to 5000rpm.

Gearbox choices remain the same as before, with a seven-speed manual offered alongside a seven-speed PDK dual-clutch unit with the choice between manual and automatic shift modes. Both work in combination with an electro-hydraulic four-wheel-drive system that has been updated with new software claimed to speed up its responses.
