I think this is a nice step in the direction of the acceptance of diesels in the NA market.

Nice to see we're making progress.

About time a diesel car gets labelled as green

Are diesel's actually better for the environment though?

Depends. Some emissions are better, some worse. They do generally get better mileage, especially in bigger vehicles. The real tradeoff comes in cost vs mileage, but that's not environmental. I'm just worried they'll become the next hybrid and the smug levels will start rising again.

I wonder about emission per kilometre.

They're better than anything with a petrol engine.
Especially with particulate filters.

Not in terms of NOx, and with the same fuel consumption petrol engines produce less CO2s per kilometre than diesels IIRC.

[Kitdy]

Overall though, are the higher nitrous oxide emissions enough to offset the lower carbon dioxide emissions?

So?

Motortrend's Car of the Year is the GT-R.

CO2 is the result of the combustion, something you can't get rid completely, and it's quite natural too, even if in big quantities is not a good thing for the environment. NOx are toxics, and much more difficult to reduce.

finally, gas exhausted by a diesel stink, if compared to those of a petrol.
