I wrote a few posts back about an eco friendly vehicle. Now that was a fun little weekend car but nothing will replace your beloved BMW. Have no fear as you can have your Beemer and your Birkenstocks. BMW’s Hydrogen 7 is the world first hydrogen-drive luxury performance automobile. It features an internal combustion engine that allows the vehicle to run on either liquid hydrogen or gasoline. On hydrogen, the vehicle emits nothing but water vapour. The BMW Hydrogen 7 will be built in a limited series, and sold to select customers in the U.S. and overseas in 2007. So, that basically means we don’t have a hope of getting our hands on one for quite some time.
