Herewith the latest spy pictures starring the next-generation Porsche 911 Cabriolet doing some winter testing.

Porsche is still testing the upcoming 2011 911 Cabriolet under extremely cold winter conditions. The car should be revealed at a major motor show before the year is up and start selling thereafter. As previously stated it features an adjustable rear wing, which is covered by the camouflage canopy, attached to the body and LED daytime running lights.

Porsche recently announced the 3.8-litre powered top-of-the-range 911 Turbo S Cabriolet worth 390 kW (530 PS / 523 bhp). It is mated to a 7-speed PDK transmission and can go from 0 - 100km/h in under 4 seconds. The new version should produce similar or even better figures.
