They certainly are not as strict and US compliant cannot be sold herr or in Europe.. Well US sales are a matter of hysteria, something that does not exist outside NA.
VM Motori is an Italian manufacturer of diesels, .RAM 3litre is built in Italy, it is a European engine that is sold globally , although it's US regs differ

This is false. The US has a stricter NOx requirement than even the new Euro 6

Although, none of this has anything to do with the topic which is about this engine being sold in the US, not anywhere else.

Glad we are talking about that as the US emphasis differs from the Global regs. Same engine different tune for the Global verson. Italian engine tuned for differing pollution regs
Your website does not even mention Nox. By the way that is a very dated chart

You might want to look at the last two charts again and what the lines mean. It is clear to see that the current diesel NOx limit is lower for the US than the current Euro 6 while the PM are the same. This is why most diesels in the US use SCR/DEF and most European vehicles don't. Not only is our NOx limit lower, but our drive cycle for our test are at higher speeds.

Also, the chart is dated from 2016 which was the last major change in regulation. Those standards still apply today. You are just trying to discredit it because it doesn't coincide with what you want to be true. The fact is our emissions have been lower than the EU regs for most of the last 20 years besides a few years in between stages(Tiers). This is why most diesels that are sold elsewhere are not sold here, and if there are sold here then they require extra emissions equipment like an SCR.
