LOS ANGELES --- At the Los Angeles Auto Show BMW unveiled its Hydrogen 7, a luxury vehicle equipped with an internal combustion engine capable of running either on hydrogen or on gasoline. The Hydrogen 7 will be built in a limited series and will be driven by selected users in the U.S. and other countries in 2007. The Hydrogen 7 is based on BMW's familiar 7 Series model. Hydrogen technology dramatically reduces CO2 emissions. Running in the hydrogen mode, the BMW Hydrogen 7 essentially emits nothing but water vapor. With all the amenities of a non-hydrogen BMW 7 Series, the BMW Hydrogen 7 is powered by a 260 bhp 12-cylinder engine that accelerates from 0 to 62.1 mph in 9.5 seconds. Top speed is limited electronically to 143 mph. The BMW Hydrogen 7 also features a dual-mode power unit --- controlled at the touch of a button --- that can switch quickly from hydrogen to conventional premium gasoline, BMW said. The car's dual-mode drive provides a hydrogen mode cruising range of more than 125 miles, with another 300 miles in the gasoline mode. With this overall cruising range of more than 400 miles, the driver of a BMW Hydrogen 7 can use the vehicle without problem even when the nearest hydrogen filling station is far away, the company said.
