Volvo Cars have released a new Facebook game in which you need to virtually drive around the world in 80 days. In the game, which has been released to promote Volvo’s super fuel efficient C30 DRIVe, you DRIVe (sorry, their pun, not mine) the C30 around the world using only your network of Facebook friends.

The C30 has a 1.6L “DRIVe” diesel engines designed for fuel efficiency and optionally has start/stop capability. The “DRIVe” engine will do 72.4 miles to the gallon which works out at 828 miles on just one tank of fuel.

In the game you need to drive your Volvo to a Facebook friend who lives as close to 828 miles away as possible. Then using the principle of six degrees of separation, the car is passed on from friend to friend, moving around the world until it makes its way back to you.

Volvo will donate €15,000 to a project that fights global warming (an environmentally-friendly wind farm in Izmir, Turkey) in the name of the team that drives around the world the most efficiently. And, for everyone who plays DRIVe Around The World, Volvo will additionally offset 99 grams of CO2; so the more people play the game the better it is for everyone.

The game started just a couple of days ago and will run 80 days until February 4, 2010. If you are the captain of the winning team you will be arguably the world’s most well-connected person!
