After breaking out the H2R concept at the Paris show, BMW is ready to put its hydrogen tech into a more practical package with a hybrid 7 that, like the H2R, uses the 6.0 liter 12 cylinder engine from the 760Li. BMW claims that since the H2R can hit 60 in less than six seconds and top 174 mph, it is the "fastest hydrogen-powered car in the world," not that there's a lot of competition. Changing the 760 engine mostly entails modifying the fuel injection system and altering intake valves. BMW is still working to improve the on-board storage of potentially dangerous hydrogen, and then of course there's the issue of finding a hydrogen fueling station. All in good time, hopefully.
