The BMW H2R ("Hydrogen Record Car") is one of the first of a new breed of racecars adapted to run on liquid hydrogen fuel. Conceived and developed in the relatively short time of 10 months under the direction of Dr. Raymond Freymann, it has set nine international speed records at the Miramas Proving Grounds in France.
The specifications of the H2R include a six-litre 12 cylinder power unit developing an output of more than 285 hp. Based on the gasoline power unit featured in the BMW 760i, BMW's hydrogen combustion engine boasts technologies such as BMW's fully variable Valvetronic valve drive. The H2R benefits from the results gained in series development of BMW's future hydrogen engine for the world's first premium saloon built for dual-mode operation, BMW launched a dual-mode version of the 7 Series, thus introducing the first car of its kind able to run on both hydrogen and gasoline.
The main modifications to the engine involve the fuel injection system adapted by BMW to the special features and requirements of hydrogen. Contrary to the production engine with fuel injected directly into the combustion chambers themselves, the injection valves in the hydrogen engine are integrated in the intake manifolds. For the specific speed record requirements to be fulfilled in this case, the hydrogen combustion engine was designed and built for single-mode operation running exclusively on hydrogen.
On the high-speed track at Miramas the BMW H2R set nine international and FIA-ratified records with hydrogen combustion engines.
