Porsche is hard at work with the development of their venerable sports car. We've seen spy photos of the car in the past but our spies have snapped it yet again with a little less camouflage this time around. Seen here winter testing, this particular test car appears to be the Carrera model.

Spied: Porsche continues development for next-gen 911

Tentatively codenamed the 992, the next-generation Porsche 911 takes an evolutionary approach for its extensive redesign. Seen here are the signature round lights and a new front bumper. The side mirror meanwhile appears to be bigger than the 991 series. As for the rest of the car, it sports the production body with no radical changes.

Porsche did cover the rear section of the car but it is worth noting that the spoiler is retracted. It hints at an active aerodynamic system which has been a feature of the 911 since the 996 era. With a heavily covered rear end, it's here is where Porsche made the most changes to the car. If one were to follow the brand's current design direction, expect LED tail lights similar to those in the Panamera.

As for engines, little information is known regarding the matter. Judging by the vents at the lower half of the rear bumper however, it is more than likely Porsche will carry on with the turbocharged flat-six engines. It is yet unknown if Porsche will still offer a naturally aspirated engine for the 992 series for the GT3 models.
