The 2019 Toyota Prius received a five-star overall rating from the NHTSA (out of a possible five stars). In IIHS testing it received a Good score on all crashworthiness tests except for the passenger side small front overlap impact, where it hasn’t been tested (Good is the highest possible score). On the new headlights test, the 2019 Prius received an Acceptable rating; as a result, it qualified for the IIHS’ Top Safety Pick rating.
On the IIHS’ front crash prevention test, the 2020 Prius received a Superior rating after it avoided collisions in 12- and 25-mph tests (Superior is the highest rating on the front crash prevention test). All 2020 Prius cars include Toyota Safety Sense-P (TSS-P), which bundles together adaptive cruise control, automatic high beams, lane departure warning with steering assist, pedestrian detection, forward collision warning, and automatic emergency braking. Blind-spot monitoring and rear cross-traffic alert are standard on the Four and Four Touring models, and optional on the, Two, Two Eco, Three and Three Touring. After some big updates for 2019 that included a new all-wheel-drive option and restructured trim levels, the Prius returns for 2020 pretty much unchanged, aside from some improvements to the infotainment experience.
The 2020 Toyota Prius has 27.4 cubic feet of cargo space that can be expanded via the standard split-folding rear seats. The Two, Three, and Three Touring models have slightly less cargo capacity at 24.6 cubic feet.
