BMW 7 series runs on cold, cold hydrogen

For BMW, engineering the impossible comes naturally. The company's engineers heard that hydrogen will be the fuel of the future, so they took a 7-series sedan and converted it. Instead of the 10-plus years of development that's gone into other automakers hydrogen-powered fuel-cell vehicles, BMW needed only a couple of years to build the Hydrogen7, which it showed off at the Los Angeles Auto Show. But the Hydrogen7 uses a completely different approach than a fuel-cell vehicle. BMW Vice President Dr. Timm Kehler told us that electric motors could provide the performance that BMW demands, so the company worked out how to use hydrogen in an internal-combustion engine. The Hydrogen7 has hydrogen and gas tanks, and can switch between them, just in case you can't find any hydrogen refueling stations.
