The Prius V wasn't a CUV. Rather it was distinctly wagonish, which is out of favor. Rumor has it (take that for what it's worth) that for 2019 will replace it with a more CUV-like version of the Prius. We'll see.
The C-Max was more of a hatchback, but seem to trail the competitors (Prius, Ioniq, Niro) in basically all stats - cargo space, mileage, etc.
Hopefully this will mean more Niro sales :-)
