Porsche’s turbo charge

Boosted flat six displaces atmo engine for entry-level Carreras


PORSCHE’S new-generation 911 Carrera makes its world debut at the Frankfurt motor show this month, boasting more power, faster acceleration and thriftier fuel use thanks to an all-new twin-turbo flat-six.

The updated 911 is due in Oz in the first quarter of 2016. Visual tweaks will include new bumpers and horizontal louvres over the engine cover. The headline, though, is the 3.0-litre twin-turbo that will power the Carrera and Carrera S.

The first-ever turbocharged entry-level Carrera (below) will have 272kW, a 15kW increase over the 3.4-litre naturally-aspirated flat-six it replaces. Torque increases 60Nm to 450Nm, and the new engine’s rev range is 100rpm wider, topping out at 7500rpm.

The new Carrera S, which will have 309kW and 500Nm thanks primarily to a more intense turbo tune, is able to hit 100km/h from rest in 3.9sec, three-tenths quicker than Wheels’ best in the current 991-series car.

Porsche claims the new engine delivers fuel economy improvements of up to 12 percent, depending on transmission.

There are minimal changes inside; mostly extra equipment.

Pricing for the Carrera will start at $217,800, an increase of almost $10,000, but includes Porsche’s PASM active suspension, front park assist and a reversing camera.

Cabriolet versions will arrive alongside the coupes in early 2016.

Despite the proliferation of turbocharging across all 911 models – bar the GTS and GT3 that reports suggest will remain non-turbo for now – the fastest and most powerful 911 Turbo (above, caught testing by our spies) will be the only one to have Turbo in its name. Porsche is expected to reveal more about the 911 Turbo closer to its 2017 launch.

Rear steer

BUOYED by the reception to rear-wheel steering in the 991 GT3 and Turbo variants, Porsche is extending availability to more 911 models. The 991 Series II update sees the Carrera S also get the active-steer system, which countersteers the rear wheels at speeds up to 50km/h for added manoeuvrability.

At speeds above this, the system increases stability by providing up to three degrees of lock in parallel with the front wheels.
