Like I said before, don't care either way and prefer a GDI engine if I want performance in a small car, but if you think modern diesels pollute more because of what you heard from your favorite Californian news site then you are dead wrong and should probably do your own research rather than being a sheep to their group think. With the amount of PM that comes out of today's GDI engines, I would not be surprised to see a particulate filters on them in the near future.
I certainly can believe this. The TSI gas engine in my VW Alltrack has terrific performance and punches way above its weight for only 170 hp in a 3400 lb car. But mileage is lackluster and the soot inside the tailpipe tells me it's not exactly a super clean burning engine.
I agree, the tailpipe in my 7 year old Cummins is much cleaner than the one in my 5 year old Audi GDI gas. NOX is the issue with new diesels, not smog or particulates.
