Considered -all in- - if you count the emissions required to keep a modern car operational (which includes accounting for much of society itself, I'd guess) this may be lower.

But that gets obscured because we already HAVE the high-emissions society with all the parts and pieces and knowhow.

After all, a vehicle that fails in the middle of nowhere may never be towed back and fixed unless it's like this one - fixable with very little.

Emission and mileage are not correlated positively. Healthy exhaust comes at a cost. An engine purely optimized for efficieny would be more efficient than those that comply with emission regulations.

But in practice, of course the old ones are worse at efficieny, too.

It has better fuel economy than anything in it's class available now.

I’d just chime in that emissions controls are about particulates NOx, SOx and other pollutants, but not CO2. Combustion of a gallon of diesel will create the same volume of CO2. That’s not to say that those other pollutants aren’t important, they’re damaging to human health, but when I hear “green” I think CO2.
