The Insight's battery and other Intelligent Power Unit components are more compact than those of the previous IMA, allowing them to be placed beneath the rear cargo area. This design element allows for both a roomier interior and the use of 60/40 split fold-down rear seats for enhanced utility.

Folding down the 60/40 split rear seats connercts the rear passenger area to the rear cargo area, creating a large flat surface that accommodates a wide variety of cargo.
