It's winter testing time and the 2011 Porsche 911 hasn't taken any time off lately. Our shooters caught this image cruising through some heavy snow still wearing much of its typical camouflage.

The only changes we can see on this test mule compared to previous prototypes are a few tweaks to the front air inlets and fog lights. The pseudo-whale cut rear end continues to hide the styling changes in back although you can see the bright LED tailligths shining through.
