One little-known fact is that (at least for Euro NCAP crash test scores), the scores are only comparable within "vehicle class", and even then by vehicle mass.

One little-known fact is that (at least for Euro NCAP crash test scores), the scores are only comparable within "vehicle class", and even then by vehicle mass. > Euro NCAP’s frontal impact test simulates a car crashing into another of similar mass and structure [...] cars which are within 150kg of one another are considered comparable. This means that at least for Euro NCAP scores, you can only meaningfully compare crash test results within a type class of vehicle, for vehicles of similar weights. Heavier, higher vehicles will usually be better-off, so a compact roadster with a 5* score is not going to come off well from a collision with a 5* SUV.
