But that article also describes a 5-door hatchback that has the same pillars as the wagon.
These terms are not fixed and not mutually exclusive.
I’ve always considered wagons to be based on sedans and with the same length as the sedan but with the trunk expanded into an open cargo area with a hatch/door.
A hatchback is similar but typically, the cargo area is shorter than the sedan and often the hatch is less vertical and contains less space.
An SUV was originally designed like a wagon but built on a truck platform and typically given 4WD.
A CUV is generally a tall wagon build on a sedan/hatchback chassis.
A crossover is more vaguely defined but is built on a sedan chassis with expanded cargo space but less boxy than a wagon and typically only slightly taller than a sedan. A lot a vehicles that are sometimes called SUVs would really fall into the crossover category (Mustang Mach-E, Hyundai Ionic 5)
