Genuine question: what about the NOx?

I remember in Belgium when the laws pushed for lower CO2, and you got an influx of all these diesel engines, as you couldn't get that low with gasoline engines (that had some power).

But a few years later people came to the realization that CO2 is the least bad of the global warming gasses, and those diesel engines emitted a lot of NOx.

Every year there was a distance that you'd have to drive before diesel made sense (as you get more miles out of a gallon, and it was cheaper per gallon).

That number kept on creeping up due to new diesel taxes, and the fact that diesel is no longer cheaper per unit than gas.

Don't forget pm2.5 ! Especially since this doesn't have an DPF(diesel particulate filter).
