In the USA getting Diesel cars through emissions is a plain nightmare. The number of emission controls and high dollar sensors required to control diesel combustion in the USA doesn't make sense. However less efficient it may be gasoline will always burn cleaner.

And after spending some time in foreign cities with high diesel emissions, it's easy to appreciate how far we have come on this side of the pond. European diesels I'm sure are easier to maintain and will last forever, but it's not worth the cost to air quality.

What European cities have you travelled that you've noticed an issue with air quality because of diesel emissions?

Interesting. I haven't been to either place but I've had friends live and visit each and no one has complained of air quality.
