21 year old developer Yuhan Zhang has designed this vehicle of the future that can "hoover" on ice, snow, water, sand and of course you can drive it on a normal road. It's powered by two hydrogen engines so it's completely ECO! The inventor claims that this car can be build because all the needed technologies do exist today. VW is very interested in this A(ll) A(reas) V(ehicle). and it looks pretty cool too!
