That's probably a good choice
That's probably a good choice to fit in the current market.
Personally, if I wanted a diesel, I'd want at least 4 L, as diesels don't (well, traditionally they don't) suffer as much fuel economy loss when operating at light loads ==> you don't have to shrink the diesel to get efficiency. Ford had the 6.9 and 7.3 F150 years back, those were fuel efficient with far older technology than today's engines. Of course they were also loud and belched out a bunch of particle cr-p that sticks in your lungs.
