BMW Hydrogen Powered Car Breaks Speed Records
BMW remains committed to launching a dual-fuel version of the cur rent 7 Series during the production cycle of the present model, which will be the world's first premium sedan built for dual-fuel operation, thus introducing the first car of its kind able to run on both hydrogen and gasoline.
The H2R Record Car, using a version of BMW's proven 12-cylinder 6-liter power plant, currently available in the 760i and 760Li Sedans, develops 232- horsepower using liquid hydrogen fuel. This translates into a 0 - 60 mph acceleration in under 6 seconds and a top speed of 174 mph.
The main modifications to the 760i engine involve adapting the fuel injection system to the special features and requirements of hydrogen fuel. Intake valves were enlarged, valve seat rings were modified, special hydrogen- specific injection valves were used and relocated to the intake manifold instead of the combustion chamber. Finally several engine management changes were made to tune the engine to hydrogen's unique combustion characteristics.
The BMW H2R Record Car was conceived and developed by BMW Forschung und Technik GmbH, a subsidiary of BMW AG. The expressive, purposeful exterior design was created by DesignworksUSA, the California-based strategic design consultancy owned by BMW Group. "We had just 10 months to develop the H2R prototype", stated Jürgen Kübler, the H2R Project Manager. But the creative engineers at BMW Forschung und Technik are used to impossible deadlines.
