Mercedes Benz do OK - 59.46 MPG in a E320CDI

Then - Peugeot 407 HDi gets 81.64 MPG average
on a long run
Here in UK we have the most expensive fuel in
the world, with variously motivated beliefs among
those that govern us that it OK to tax personal
mobility to the point traffic is reduced to a conscience
salving level while at the same time delivering
a huge financial bung wrung out of the remainder.
More than 70% of our fuel charge is tax! A litre
(thats 2.2 pints!) of fuel here costs between 0.96
and 1.04 UK pounds depending on where you are. Diesel
is much cheaper to produce, but is then taxed to
beyond the price of unleaded on the grounds it is
"dirty". In fact, modern diesels produce *less*
pollutants than petrol cars.
As for "hybrid"
cars, or any other electric variant, I shall only
be impressed when the makers can assure us that
all the electric component did not start out at
some point as fossil fuel burning in some power
station somewhere, and was then converted and stored
and shoved about with varying efficiency at all
stages before it finally ended up heating the brake
discs. This sort of stuff represents a bigger contribution
to global warming than if we put the fuel in a good
engine in the first place.
The whole thing
about fuel is the hydrogen in it. It needs to join
oxygen to release the energy and go back to water.
Unfortunately, in most fuels, the hydrogen is only
available locked onto a load of carbons, which will
make CO2 as the price of getting joined with oxygen.
I guess some futuristic fusion-powered tokomak working
hard to split sea water into hydrogen and oxygen
so we can have a (dangerous!) personal mobility
fuel is how to save the planet. Then again.. is
hydrogen any more dangerous than petrol.. ? Hmm..
