Anyone knows this car?- a Hydrogen V12 (750hl)

it is an E38 750hl….yes it is very rare and at the Moment you will see none. They were delivered to 100 German Politicians and Movie Stars to test them.
They run on Hydrogen Gas. That is right! The use H2 in a combustion engine (V12). The car has less power (250bhp) than the Petrol equivalent due to different engine Setup. But I think that concept is great. At the Moment it is put on a stop, because it uses way more oil to creat H2 than it saves. And plus is that a new Design for the fuel tank had to be developed, but still after 4 Days over 50% of the hydrogen Fuel was diffused throgh the walls. But a sideaffect is that BMW discovered that Rotary engines actually work better for this cause the hydrogen creates water in the engine, which is bad even in vaporised form. So it Needs some oil constantly to be lubricated. Something a rotary engine already has. Look it up in the German Wikkipedia it is way better described.
