Do you have a lot of facebook friends? Like, more than a hundred? You're going to need them if you want to complete Volvo's Drive Around the World challenge. To help promote their new energy efficient car, the company has created a rather nifty little facebook game. The objective is simple, drive the virtual car around the world, hopping from friend to friend in the quickest way possible. The catch? The maximum range of this hybrid monster is 1330 miles, so not only do you need a good number of friends, but you need them to be located in some pretty interesting places. Don't worry, bodies of water don't count. But still, who's got friends in the middle of Siberia? Or Arkansas for that matter? Check out the video to see how you can play, and win $15,000 dollars to help save the earth at the same time.
