From the perspective of BSFC it's consistent, but emissions tend to be the opposite. At least for
older diesels, particulates go up w/ load, NOx/CO goes up w/ load and speed, and HCs are roughly the same.

That's pretty much what manufacturers have been moving towards for the past decade or so via drive-by-wire, variable cam phasing, eleventy billion speed automatic transmissions, cooled EGR, and so on.
