The BMW H2R ("Hydrogen Record Car") is a racecar adapted to run on liquid hydrogen fuel. It was conceived and developed in 10 months under the direction of Dr. Raymond Freymann.

The H2R’s 6.0-liter V12 engine, which draws on BMW's Valvetronic and Double-VANOS technology, is based on the 760i’s gasoline-fueled powerplant. This H₂-powered vehicle generates {{convert|232|hp}} achieved a top speed of {{convert|187.62|mph|km/h||abbr=on}}.^[1]

Technical data

On the high-speed track at the Miramas Proving Grounds in France, the BMW H2R set nine international and FIA-ratified records for cars with hydrogen combustion engines.

Maximum speed: {{convert|300.175|km/h|mph|3|abbr=on}}
Engine: twelve-cylinder ICE, running on hydrogen
Bodyshell: aluminium space frame structure
Outer shell: carbon fibre-reinforced]] plastic
Vehicle dimensions: {{Convert|5.40|m|in|1}} long, {{Convert|2.01|m|in|1}} wide, {{Convert|1.34|m|in|1}} high
Vehicle weight including driver: {{convert|1560|kg|lb||abbr=on}}
Drag coefficient (cw): 0.21

BMW Art Car Project: Your Mobile Expectations

In 2007, Olafur Eliasson was commissioned by BMW to create the sixteenth art car for the BMW Art Car Project based on the H2R. Eliasson and his team removed the automobile's alloy body and instead replaced it with a new interlocking framework of reflective steel bars and mesh. Layers of ice were created by spraying approximately 530 gallons of water during a period of several days upon the structure. On display, the frozen sculpture is glowing from within. Called Your Mobile Expectations, the vehicle was on special display in a temperature controlled room at the San Francisco Museum of Modern Art from September 8, 2007 to January 13, 2008.^[2]
