Funny you should mention the lobby. The US auto lobby was the reason the US NOx diesel emission requirements are more stringent than EU in the first place, specifically disadvantaging European diesel cars (which are much cleaner overall).

No, that was a result of the Clean Air Act Amendments of 1990 for the reduction of acid rain. Though it was targeted towards industrial emissions of SO2 & NOx, but stricter regulation for vehicles were an additional effect.
>specifically disadvantaging European diesel cars
That's a weird argument given that diesel passenger vehicles in the US are held to the same standard as gasoline ones, but to a separate standard from their petrol counterparts in the EU. I mean, one could argue the opposite, that an EU emissions policy favorable to diesels amounted to an equivalent 13-16% import tariff. [1]
Several domestic rather than just foreign diesel engine manufacturers were also penalized for using defeat devices in 1998.[2]
> (which are much cleaner overall)
That's quite arguable, trading lower CO2 & CO for increased NOx & PM.

Surely car manufacturers didn't have a say, which is why US and EU emission standards look like this https://longtailpipe.com/wp-content/uploads/2015/10/us-europ... .
>same standard as gasoline ones
Well duh, let's keep diesel cars to petrol standards so that their benefits don't matter and their disadvantages are prohibitive!
