The hydrogen is present in a lot of molecules: water, sugar, proteins, hydrocarbons.
The Car emits virtually nothing, just water vapor. But, because the infrastructure for refueling a hydrogen is not large, the BMW Hydrogen 7 use a traditional V12 engine also runs on gasoline.
To justify the choice of the hydrogen, BMW said:
"It is the only fuel that can allow for a reduction in the overall emission cycle, while meeting our energy needs in a sustainable way. Besides, not many fuels can be produced from renewable sources such as sun, wind, water and biomass."
The car is available in Munich, Berlin, Tokyo, Los Angeles... nowhere in France, because no station of hydrogen built, No BMW Hydrogen 7 will be sold, because automobiles are only available in leasing, in the same price as a BMW 760 Li with a complete maintenance contract. This BMW is not a car for all, but show advanced technological which makes BMW. And not pollute during journey, while continuing to benefit from an automobile of the highest level. Neither Mercedes nor Lexus can offer it today.
