Volvo D11
The light option, around 400 pounds under the D13 and aimed squarely at regional work where payload is the constraint and the hills are not.

In the exhaust
DPF and SCR
The first greenhouse gas phase targets the whole vehicle rather than the engine, so this era is as much about aerodynamics, tyres and axle ratios as combustion. Downspeeding becomes standard: tall gears, low cruise revs.
Known issues
The same EGR and aftertreatment family as the D13, worked slightly harder for the same load.
Verdict
Genuinely worth considering for regional and bulk work. Under-specified for over-the-road at 80,000 pounds.
