Diesel engines these days are - in their (relative) cleanliness, performance and technological sophistication - very different animals from the clattering beasts of yesteryear. And their low CO2 ratings continue to draw new buyers in Europe - despite the recent spike in diesel fuel prices. But you do pay a premium for a diesel car and the payback period in terms of lower fuel bills may be longer than people think. Some reviewers have complained also that the increasing technological wizadry inside the diesel engine is creating reliability issues. And I have heard some talk that the public health concern associated with very small (nano) particulates may be about to rear its head again. Those traps don't catch everything.
