Just when we thought the next generation 911 would be set to the side until its debut at the Frankfurt Motor Show, our spy photographers were able to catch even more images of the future model. Better yet, we were able to get spy shots of the 911 Turbo that include that big rear wing, a feature that was vacant on the prototype captured in its winter and spring testing, but highly anticipated for the production model.

Aside from the elaborate rear wing, this new prototype features enormous air intakes placed against wide fenders, totaling up all the proof we need that this is the most powerful Porsche->ke1 in the 911->ke282 line-up.

The 2013 Porsche 911 Turbo will be powered by a 3.8-liter flat-six engine that will deliver about 550 HP, a bit higher than the 530 HP found in the current 911 Turbo. Porsche will also offer both brake regeneration and stop start systems to help reduce fuel consumption by 12%. The new Porsche-Doppelkupplung (PDK) gearbox will also be offered and with no less than seven forward gears, it combines the driving comfort of a converter automatic transmission with the dynamic gearshift of a sequential racing gearbox.

Expect to see the new generation 911 Turbo at the 2012 Geneva Motor Show March, with sales beginning later on in the year.
