BMW had a prototype hydrogen car in the 80s believe it or not. It was a 5er. The 750h has been around for a lil, mainly a handful of cars to take to car shows and what not, but all are functional. I like the idea of being able to run the car on either gasoline or liquid hydrogen. Makes for a flexible car that can be practical with just a few, if any, hydrogen filling stations.
