In May, we let you know about a contest from Wired.com where you could submit a video describing how you are reducing your carbon footprint and win an early chance to drive a Chevy Volt.

Wired.com has announced the four lucky winners who will head to Detroit next month to test-drive the Chevrolet Volt.

Congrats to Simon M., Guy M., Patrick, W., and Ron F.! (View their videos.)

Note: Chevrolet plans to post updates about the contest winners’ driving experience on the Volt website. If there is any thing of note in the updates, we’ll be sure to share them with our readers.
