The all-new 991 Porsche 911 is already up and away here in Australia, but the range-topping Turbo variant isn't expected to debut until early next year.
Development on the iconic 911 Turbo is well into its final stages though; a pre-production prototype of the German supercar has been spotted during shakedown testing at the famed Nurburgring this week.
Although it's a clean-slate design, the 991-generation 911 Turbo will follow the template established by its predecessors and the new Carrera 4 - fatter fenders, intercooler-ducting in the rear quarter panels and a prominent rear spoiler.
There's also the usual heavily-vented rear bumper with integrated quad-exhaust outlets, and larger radiator openings in the front bumper.
Powertrain details have yet to be announced, but an evolution of the current 997 Turbo's 3.8 litre flat six is likely to see service in the 991 Turbo.
Reports have also been circulating that the new 911 Turbo will feature a triple-turbocharger layout. The third turbo would supposedly help reduce turbo lag, and broaden the engine's powerband.
Power? Expect a substantial rise over the current model's 390kW/700Nm, with a power output similar to the 405kW of the 911 Turbo's arch-nemesis, the 2012 Nissan GT-R.
As with previous generations, drive will be taken to all four wheels.
The seven-speed H-pattern manual used by the 2012 911 Carrera is likely to be the standard transmission for the 2013 911 Turbo, with the dual-clutch PDK automatic available as an option.
