I think the biggest problem here is emissions equipment, and the EPA cracking down on the diesels. Most, if not all of the problems come from the emissions equipment. It's not any different with the diesel pickup trucks. Things are getting better, but they aren't quite there yet. It's still new technology. The same thing happened back in the late '70 with gas engines. They were poor performers, got worse mileage, and ran like crap.

All this just seems pointless. The diesel engines are burning more fuel due to regens, so that they can burn cleaner. Wouldn't it just be better if they got better mileage and didn't burn the extra fuel to begin with? You can't tell me burning more fuel, doesn't make more emissions then a truck that gets better mileage because it runs the way it's supposed to. Maybe the emissions savings comes from trucks that sit in the shop because they don't run with all the particulate filters all clogged up!
