its a bridge between Sweden and Denmark

Can we please stop talk about bridges!

The only important bridge here is the new dual mode engine: a bridge between petrol and hydrogen era.

Another interesting info by BMW spokesman:

The car will be avialable in april ?

For comparison:

Mercedes F600 Hygenius prototype



- fuel cell with system pressure of 700 bar, generating electricity for the electrical motor (<--> BMW injects H2 into the combustion engine)
- weight of this car > 2 tonnes
- 115 HP (85 kW) and 350 Nm torque
- hydrogen consumption equivalent with 2.9 L diesel/100 km
- enough power to provide a caravan, hifi tower or countryhouse with power (energy consumption by average household: 0.8 kW/day <--> 85 kW)
- autonomy: 400 km

IMO, every step in the direction of an environmentally friendly transportation is a milestone as such. Don't look at it from a perspective of BMW vs. Mercedes, but from the point of past vs. future. I really hope they (= all car manufacturers) can further improve the technology behind it, save weight and increase power output. Imagine a world without the tropospheric ozone problem (NOx + sun = troubles), greenhouse effect (CO2), fine dust (diesel engines!!), lead or benzene contamination (petrol), ... No need to feel ashamed when you push the accelerator pedal to the floor, because emissions are non-existing. Only problem maybe: the generation of hydrogen gas by electrolysis requires electricity itself...

true, but can't it be possible to just get a hydrogen plant started, and then use some of the energy it produces to make its own electricity. So eventually having a selfsustaining plant, with just the need of a fossil fuel kickstart?

Thanks for that Andreas.

I didn't read your first post carefully enough


I have heard that they will be very expensive and so most will be leased to selected customers.

True. They even won't be leased, but it will be rented by BMW to some selected custumers - the ones BMW think will be best Hydrogen energy ambassadors.

Basicly it is a production car (limited production), but it is not in the market - the only difference is that till now all H7 were used in-hous, yet now BMW decided (marketing reasons) to rent some units to selected drivers outside BMW.

It's a first step ...

So do you reckon for the next 7er, there will be a hydrogen model on sale to the public?

Sometimes in the 2nd half of its lifecycle perhap - if market will be ready by then (broader availability of hydrogen filling stations; acceptable price of liquid hydrogen).

As you can se the car is ready but supporting infrastructure is not.

lol!
