Price per gallon (or litre, actually) is about 15..25% cheaper than
unleaded in continental Europe (Germany, France, Spain, Belgium, The
Netherlands, Luxemburg, Portugal, Italy,...), except for some countries
such as Switzerland (no price difference). The difference used to be
larger (about 40%) but since the sale of Diesel cars has soared, we are
on our way toward equal pricing. I think that this can be traced back to
the refining process were heavy oil fractions are used to make Diesel
and light oil fractions are used to make Unleaded. When the Diesel fleet
exceeds the Unleaded one, Unleaded will probaly be cheaper (actually,
Diesel will be more expensive). And then, there are the taxes (which
account to about 50% of the price at the pump over here!).
Modern high-pressure direct-injection fed turbo-Diesel engines are
inherently very efficient, so the typical Diesel version of a car has a
better mileage than the equivalent petrol version (up to 30%
improvement). And now that most European (VW/Audi, Fiat, Renault) and
Japan (Honda, Toyota, Isuzu) manufacturers do produce decent Diesel
engines, you can even have some driving pleasure in these cars. I know I
do (after having said for years that there was no way I would ever drive
a Diesel).
BTW, the Japanese and Italians are now on their way to squeeze out up to
100HP (76 KW) from a puny 1.3 litre turbo-diesel (take the latest
iteration of the Fiat-designed JTD 1.3 engine, for instance).
In France, Diesel cars currently outnumber petrol ones. Which makes me
wonder if maybe Diesel could be a bad idea, after all ;)
Driving a Diesel-powered car frequently since two years now, I am pretty
sure these cars could be very successfull in the States, as these are
even better adapted to the more relaxed type of driving you have over
there (driving on the torque) rather than the stuggle-for-life driving
style that is often practised here. An additional factor is that GM
actually controls Opel and Isuzu, so the technology should be readily
available to Detroit.
IMHO, a possible drawback of high performance Diesel engines might be
the very fine particules that can be released from the exhaust, which
can penetrate deep in the lungs and might prove to be strong carcinogens
in the long term. That, and the noise which is definitively less ***
than a screaming Honda VTEC revving 8000 RPM.
