"Closely following a sighting of a Hydrogen-powered 7 series during testing, BMW officially announced the Hydrogen 7 today. The car is touted as the first hydrogen-drive luxury performance automobile for everyday use. The BMW Hydrogen 7 will be built in a limited series, and sold to select customers in the U.S. and overseas in 2007. The engine in the Hydrogen 7, a derivative of the 7 series 12 cylinder engine, is capable of running on gasoline or hydrogen, and produces 260 hp. The car will accelerate from 0 to 62.1 mpg in 9.5 seconds. The ability to run on both gasoline and hydrogen gives the Hydrogen 7 a range of more than 400 miles. The high tech hydrogen storage tank has a capacity of approximately 17.6 lb of liquid hydrogen, giving the Hydrogen 7 a cruising range in hydrogen mode upwards of 125 miles. The gasoline mode accounts for an additional 300 miles of cruising range. The driver is the one who decides which fuel to use, with a smooth transition between both operating modes, since the engine power and torque remain identical regardless of the fuel used."

looks interesting, definitely would be a smart buy for major companies shuffling the execs around. but who knows how much this will cost ontop of a current 7 series.

It only makes 260HP on gasoline too? wow seems like the hydrogen Renesis is far more powerful than this hydrogen V-12, in terms of displacement. The hydrogen Renesis makes 210HP with gasoline and 110HP with hydrgoen. It travels 340miles on gasoline and 60miles on hydrogen.

I guess that certainly boost my impression towards the RX-8 and hydrogen. Isn't the RX8 hydrogen tank only 19 gallons?

I'm trying to decide if that is good power for hydrogen or just crappy power for gasoline. I would have to say a little of both but good power for hydrogen isn't much to brag about so I'd have to say that power level sucks for that engine no matter what it's running on. Then again hydrogen sucks as a fuel source so that's to be expected.
