Modern diesel cars are not economically viable if you reduce NOx emissions down to acceptable rates. That’s exactly why all the manufacturers cheated, to be able to claim lower emissions while maintaining engine reliability and MPG performance. If you actually reduced emissions properly, the resulting engine wouldn’t be economically viable compared to their gasoline alternatives.
