High Quality Content by WIKIPEDIA articles! The BMW Hydrogen 7 is a limited production hydrogen vehicle built by German automobile manufacturer BMW. The car is based on BMW's traditional gasoline powered 7-series line of vehicles, and more specifically the 760Li. It uses the same 6 litre V-12 motor as does the 760i and 760Li; however, it has been modified to also allow for the combustion of hydrogen as well as gasoline, making it a bivalent engine. Unlike many other current hydrogen powered vehicles like those being produced by Honda, General Motors, and Daimler AG - which use fuel cell technology and hydrogen to produce electricity to power the vehicle - the BMW Hydrogen 7 burns the hydrogen in an internal combustion engine.
