danny_galaga:

what is it with the car manufacturers? today i saw a billboard for a diesel chrysler 300 or whatever it is. why? if you want a big car, be prepared to pay for the fuel. dont fill the air up with particulants. it doesnt matter how fancy you get with diesel motors, they still spew dirty, dirty exhaust. i really hope they stop making diesel cars soon...

I was under the impression that a properly serviced diesel engine was actually cleaner.

Diesel engines also have a wider range of fuels to select from with fewer (eg cheaper) modifications to the engine. IIRC, the original diesel engine burned some kind of vegetable oil, peanut or something. Present day diesels are much cleaner than those as recently as the 80's, they're better at burning Biofuels in less refined form, they appear to be less susceptible to air pressure differences, and I'm told they're easier to maintain.

AtomSmasher:
I believe diesel engines produce less green house gases, but more soot and other particulants that cause a different type of problem.  They have developed filters for diesel engines that filter out the vast majority of the particulants and I know that about 5 years ago VW used to offer the filter as an option on their diesel cars, but I have no idea if they've since become a standard on all diesel cars.  My guess is they have, but my google-foo appears to be weak so I can't find any info on it.

TOK:
Prepare for a pretty large wave of new diesel powered cars and trucks. In addition to the 300, Chrsyler/Jeep is going have new clean diesels in some Jeeps. They actually had an old style diesel Liberty for one year, discontinued this, and it's returning as a new clean diesel. I think their now-over affiliation with Mercedes drove this.

Anyone looking for info on the new wave of clean diesel stuff should probably be able to find it by searching for low sulfur diesel. This fuel, combined with new filtered exhaust and fluid injection technology that cleans up emissions will get new diesel cars to meet the 2007 passenger car diesel emissions requirements older engines could not. They actually make great sense for SUV's, since you get the monster torque for towing along with better mileage than a gas V8.
