Actually Robert, they cleaned up the gasoline engines in the US about 20 years in advance of the diesels. Cats, fuel injection, EGR, and unleaded/oxygenated fuels.
They did not take the sulfur out of gasoline yet, and they did not install particulate filters yet. One look at the tail pipe of a clean diesel versus a gasoline model on a 2009 or newer VW jetta, golf sportwagen, beetle or passat with a white glove test will make my point. You can also do the same with an Audi Q7 or Porsche Cayenne. The gasoline versions will have filthy tail pipe soot and residue on the gas models.
I agree with you on the tailpipe test for those you mention... And I also have a '96 F150 that will pass your white glove test. It's in the tuning , throttle response on the Ford sucks while others have optimized the driving experience and probably are as liberal as the regulations permit with open loop fueling. Yes, I realize Gdi makes more PM.
My point being the gasoline engine cleanup journey started earlier and is more mature than diesel. Hopefully serious teething problems are less likely.
