In Reply to: Mosoon, how do you feel about the diesel engine? posted by (eom)Dave N on October 18, 1999 at 17:19:23:
Well I´m very happy with it.
With the developments of the diesel engine for the last five years many of the old drawbacks are now gone.
The main reason is still of course the very good mpg but you also gain in longer life for the engine,
Longer service intervals and great torque.
The performance of the diesels today can rival that of many gasoline engines.
Different methods have made this possible but most have to do with the injection of the fuel into the cylinders (common rail and other techniques).
Turbo with variable blades have made the torque available over a greater rpm range and (BMW especially) has developed insulation of the engine that reduces the noise and vibration of diesels to very low levels (except for at the immediate start).
Diesel autos seems to be a european thing and
the ranking in Europe of diesels of different brands seems to be that the ranking right now goes something like this:
5. Fiat (inventors of Common Rail), Alfa, Peugot, Citroen
All german premium brands have show monstrous luxury and sports cars with diesel engines.
The modern diesels have good performance in enviromental issues compared with older diesels (and trucks etc.) but one looming issue is the debated impact of the microparticles that these (and other high-efficency engines) emitt.
There seems to be developments coming with super-particle filters or burningchambers (peugeot-citroen) for these particles but until these are on the market the debate continues.
The economical break-even point for buying a 320D
instead of a 323i is reached at between 4.000 - 12.000 miles per year in most european countries
(depending on taxes, price gas/diesel and price of car). To simplify a bit southern europe is soon to be dominated by diesels while northern europe (like i think the UK in special) is more moderate in (tax) enthusiasm of the diesels.
