The manufacturer provided their new “child” with the good cabin material; even the plastics are of the high quality. Some of the more powerful competitors might offer a more fancy design, but new Kia’s cabin is pretty functional. As for the space of this vehicle, the cargo room may appear to be smaller (compared to the non-hybrid model) than expected due to the lithium-ion battery pack.

The lower anchors are deeply in the seats.
