BMW Hydrogen 7 – Fuel Cell Concept: Say it ain't so: the Ultimate Driving Machine has gone the way of the tree hugger. The automaker that has made a name on the sweet music of automotive power and grace has indeed jumped into the hydrogen game – but has done so in their own BMW way. Instead of building a fuel cell car that gets lousy performance and carries a weird, futuristic interior, BMW hollowed out a 760i and stuffed it full of a bunch of new technology, namely a 12-cylinder engine that runs on gas and hydrogen. Then they bolted on a nice high tech tank to hold the hydrogen, washed their hands, had a sandwich and went out for a drive in their new Hydrogen 7 Concept car.
