I for one hope we do make the “same mistake as Europe” and get a lot more of the small, efficient diesel vehicles that are available in Europe. And I may be mistaken, but I believe diesel engines produce LESS CO2 than gasoline engines, not the other way around. In fact, the only area they’re worse than gasoline is the whole NOx issue.

Joe, I hate to be picky, but since we're talking about confusing people with misleading statements, I thought I should speak up.

Nitrous oxide is a GHG, but its symbol is N2O and has 310 times more impact on global warming than CO2.

NOx (or NO2) is Nitrogen Oxide and is a contributor to air pollution.

NOx is a problem for diesels.

The truth behing NOx production by diesel engines is too true. The effect on global warming by NOx is much greater than CO2. Here is a quote from Wikipedia regarding this problem.

"While its radiative warming effect is substantially less than CO2, nitrous oxide's persistence in the atmosphere, when considered over a 100 year period, per unit of weight, has 296 times more impact on global warming than that per mass unit of carbon dioxide (CO2)"

Please don't think that diesel engines are better for the environment than gas!

Don't make the same mistake that is beeing made in Europe! Ok, diesel engines can get better mileage then gas engines but how about the emissions? A liter of diesel produces more CO2 then a liter of gasoline, but it also produces NOx, particles and has a higher level of sulphur.

CO2 can be captured by planting trees, the rest can't and the particles will be either on the air or in or lungs and it will take them 50 years to disapear...

Ok, you can say they now have particle filters but who is willing to pay around $300 for it's maitenance every 40.000 miles?
