BMW Hydrogen 7 finishes the Hydrogen Road Tour
The BMW Hydrogen 7 – a hydrogen-powered luxury sedan
– ended a more than 4,000 mile cross-country journey
in Los Angeles that featured hydrogen-powered cars
by the world’s leading automakers in an event called
the 2008 Hydrogen Road Tour. The purpose of the
tour was to show that automakers and energy producers
are doing their part to move away from fossil fuels
to hydrogen, and showcase the cooperation among
lawmakers, NGOs, the DOT, DOE and the industry.
BMW provided a fleet of four hydrogen-powered cars
– two BMW Hydrogen 7 mono-fuel vehicles that use
only liquid hydrogen and two BMW Hydrogen 7 bi-fuel
vehicles that can switch from hydrogen to gasoline.
Logging a “strictly hydrogen” cruising range of
over 200 miles, the BMW Hydrogen 7 mono-fuel completed
the two-week, 31 city tour while leaving only a
trail of water vapor behind. The 200-mile cruising
range is equivalent to over 25mpg. In the BMW Hydrogen
7 bi-fuel vehicle, the cruising range topped 125
The Hydrogen Road Tour is a partnership with the
U.S. Department of Transportation, U.S. Department
of Energy, the California Fuel Cell Partnership
and the National Hydrogen Association. In addition
to BMW, participants included Daimler, GM, Honda,
Hyundai-Kia, Nissan, Toyota, and VW. Providing clean,
domestically produced hydrogen fuel for the tour
were Linde, BMW’s hydrogen fuel partner for the
Tour, and Air Products.
The tour fleet included the mono-fuel version of
the BMW Hydrogen 7, equipped with a V12 internal
combustion engine (ICE), which has been engineered
to run exclusively on hydrogen. It was created to
showcase the zero CO2 and low emissions potential
and feasibility of a dedicated hydrogen internal
The Hydrogen 7’s V12 mono-fuel ICE produced no CO2
and near-zero emissions. In fact, the tailpipe emissions
were so infinitesimal that they pushed the limits
of current emission testing technology.
Independent authorities, including the Argonne National
Laboratory (ANL), have confirmed these results.
ANL conducted emission tests on BMW Hydrogen 7 mono-fuel
vehicles in early March 2008 and found that not
only were the emissions negligible, but when running,
the vehicle actually cleaned the air.
Recent studies have also confirmed the water emitted
by the Hydrogen 7 is safe to drink.
Exhaust from the mono-fuel Hydrogen 7 tested by
FGL Environmental was found to be well within the
limits set by the United States Environmental Protection
Agency for safe drinking water standards. The Maximum
Contaminant Limit (MCL), is the maximum limit set
by the EPA for chemicals found in drinking water.
Results showed the MCL from mono-fuel H7 emissions
to be in compliance with the health safety standards.
