A number of new Porsche 911 (code name: 992) prototypes have been filmed testing at the Nurburgring, including an especially intriguing Turbo mule.

As has always been the case, the next-generation 911 Turbo will be the most well-rounded model in the range, offering stellar performance with exceptional driveability and comfort. The new version will, however, look much more aggressive model than the outgoing model.

If you skip to the 1-minute mark in the video below, you’ll see a blacked-out 911 Turbo prototype being pushed to its limits at the circuit. As it rounds the corner, its all-new active rear wing comes into view, and it is much more prominent than the ones attached to previous Turbo models.

A similar prototype filmed racing a McLaren 720S last month was fitted with the same rear wing. In its deployed position, the wing extends much further up than previously and will inevitably help to increase downforce, which should make the new 911 Turbo even faster around a racetrack.

Powertrain details about the new 911 Turbo and 911 Turbo S are limited, but the two models will probably use a tweaked version of the 3.8-liter twin-turbocharged flat-six used by the current model. In standard Turbo guise, this engine could be tuned to deliver around 600 hp, while the Turbo S may benefit from up to 650 hp.

Straight line performance from the pair will be absolutely blistering and they’ll be able to comfortably reach 62 mph (100 km/h) in less than 3 seconds while blasting to top speeds exceeding 200 mph (320 km/h).
