I remember flipping through tv channels and one day I think ESPN had an auto show coverage of an auto show with the hydrogen Rx8. I think it makes somewhere around only 120hp if i remember correctly

Well after a short search found C&D article from Tokyo show
"Mazda RX-8 Renesis Hydrogen Rotary
Yes, we know there are almost no hydrogen filling stations, but might there be more if there was a fleet of cars on the road that could run on either gasoline or hydrogen at the flip of a switch? That’s the promise of Mazda’s rotary. You see, in a piston engine, the combustion takes place in the same physical space as the intake and compression events. This causes the walls of the cylinder to get very hot, causing the hydrogen pre-detonate, which requires the compression ratio to be reduced to a point that would make using gasoline impossible or highly inefficient. But in a rotary, the intake is in one area of the rotor housing, and combustion is in another, so the gasoline compression ratio also works for hydrogen. The running model does, however, lose quite a bit of power when burning direct-injected gaseous hydrogen: 108 hp versus 207 on gasoline. Still, this is probably the most marketable hydrogen powertrain concept of our time."

Nice photos man. Thanks! :D Loved the "civic" engine pic too.
