In BMW Germany h stands for hydrogen, not hybrid
    As many BMW owners and enthusiasts are most likely aware, BMW has
said that it will begin producing a new 7-series that will use a
hydrogen combustion engine.  What many may not know, is that they are
on track to release this car-to the consumer market-within the next
two years!

    With many car makers, such as Ford, GM, Toyota, and Honda, building
hybrid gas-electric engines, BMW has taken a different route and been
developing the technology for a hydrogen combustion engine for some
time.  This new engine is slated to first appear in the BMW 745h to be
released in 2008.  While their R&D cars have been seen for some time,
new photos have surfaced that show what appears to be an otherwise
normal looking 7-series with a hydrogen storage tank in the trunk.

    This new engine is not powered by hydrogen fuel cells, but rather
an internal combustion engine that is reported to be capable of running
on either hydrogen OR premium gasoline. The fact that this engine is
capable of running on current gasoline or hydrogen will help mitigate
the current lack of a consumer hydrogen infrastructure.  From reports
on the web the 745h will have a 4.4-liter V8 engine, while running on
hydrogen it will produce 184 horsepower, have a top speed of 133 mph,
and a cruising range of 190 miles.  Coupled with the standard tank of
gas' cruising range of 400 miles, this car should be able to travel
nearly 600 miles before a fill up is needed.  This engine is similar in
size to that found in the standard BMW 745i, but does not produce quite
as much horsepower (325 vs. 184), but its use of hydrogen, and the fact
that there would be no pollution emitted, more than makes up for this
difference in my mind.  What is not mentioned is price; a standard
7-series will run you between $0k and $20k, but I assume this new
model will fall into the category of "If you have to ask, you cannot
afford it".  However, as with all tech, early adopters pay the price,
so hopefully in time, this technology will be affordable for the masses.

And you will probably have to travel that far to find a place to refill with
hydrogen.

In 2003 !!!

And who wants to drive around with a load of hydrogen in the back.
Ahh, I forgot the Germans have always been big on hydrogen

Oh now, to be a bit fair, the Germans only used hydrogen in the Hindenberg
because the US wouldn't sell them the helium.  (at least that's the story as
I remember it).
