Porsche has revealed that the 911 Turbo flagship will receive a significant increase to power output and revised styling ahead of the Turbo and Turbo S unveiling in Detroit next week. Both coupe and cabriolet variants will arrive in Australia this May.

911 Turbo S

The 911 Turbo range will feature the same 3.8-litre bi-turbo six-cylinder engine configuration, however modifications to the cylinder head inlet ports and increased fuel pressure delivered via new fuel injectors provide a 15kW increase in power to total 397kW.

The 911 Turbo S will reach a total output of 427kW thanks to new turbochargers with larger compressors.

The engines will also be equipped with ‘dynamic boost’, a function to improve throttle response. The new feature maintains the charge pressure during load changes by interrupting fuel injection while the throttle valve remains open. The effects of this feature will be especially pronounced when Sport and Sport Plus modes are engaged.

Both the 911 Turbo and Turbo S increase their top speed, to 320km/h and 330km/h respectively.

While the headline for the new cars is their increased performance, Porsche is adamant that the cars will be capable of even lower fuel consumption figures due to improved engine and transmission management with revised gear change mappings. The coupe achieves a 9.1L/100km claim, the cabriolet drinking a little more at 9.3L/100km.

A standard feature for the updated 911 Turbo range the Sport Chrono Package. This includes a new rotary dial that is found on the 918 Spyder-inspired GT sport steering wheel. The dial will give the option of four modes; Normal, Sport, Sport Plus or Individual which allows a user customised configuration.

Also part of the Sport Chrono Package is the Sport Response button that when pressed will precondition the engine and transmission to produce optimal acceleration for up to 20 seconds. This function will be predominantly useful for instances such as overtaking and can be switched on at any given time.

The onboard Porsche Stability Management (PSM) will have a PSM Sport Mode on the new 911 Turbo models. This can be engaged via a button on the centre console. When pressed, PSM is put into a highly sports oriented mode. It alters the PSM’s intervention threshold and provides settings best suited for the racetrack. The PSM can also be completely turned off by holding the PSM button down – something best attempted by more experienced drivers.

The new 911 Turbo range has also had a significant cosmetic facelift, borrowing some design cues from the Carrera models. New 20-inch wheels can be found on both models that are half an inch wider on all four corners.  A newly formed front end with wider stance has been designed featuring side and central air intake airblades and twin LED front light strips.

Up the back a bolder tailpipe setup caps off a redesigned rear exhaust section.

Technological interior goodies include a newly-developed infotainment system complete with a multi-touch monitor, navigation as standard and a plethora of connectivity options. Like previous 911 Turbo models the car will have a Bose sound system, although a Burmester high-end surround sound system can be installed as an option.

The 2017 Porsche 911 Turbo and 911 Turbo S will be launched in Australia in May with pricing starting at $384,900 (excluding on-roads) for the entry level Turbo and $406,400 (excluding on-roads) for the Turbo Cabriolet. Turbo S variants will start at $456,500 (excluding on-roads) for the coupe or $478,000 (excluding on-roads) for the Cabriolet.
