It's funny that people can mention hybrid cars being more enviormentally friendly, yet the manufacturing process used to build the batteries for such vehicles does a lot of damage to the enviorment too. More so, they say, then manufacturing normal internal combustion powered vehicles. The hybrid cars themselves are not so eco friendly in that respect. Their advantage is they consume less fossil fuels AFTER being built, which helps our country free itself of reliance on fossil fuels for powering vehicles, but not for manufacturing them! You just can't win.

Likewise, diesels that consume more fuel during regeneration, to burn cleaner, don't seem to be gaining anything either.

What was said about diesel engines lasting half as long because of the designed emissions equipment is true. Fuel injected on the exhaust stroke, during regeneration is not burnt in the cylinders, and as such a good amount of that unburnt fuel washes down the rings, contaminating the engine oil. I think most of us know what happens when oil is diluted with fuel...
