The Insurance Institute for Highway Safety (IIHS) did its worst to the new Scion xD, and after performing both the frontal offset test and a side impact test with the standard front and rear head curtain airbags and front seat torso airbags, the xD came away with ratings from "good" to "average."
On the frontal offset crash, the IIHS found that the dummy's movement was well controlled, although the rebound caused its head to strike the roof rail. The possibility of injury to the neck and chest garnered an "average" rating, while the safety cage, foot protection and restraint system were all rated as "good."
The side impact test rated the Scion xD as "good" all around, save an "average" rating for the structure/safety cage portion. Although there's no IIHS data for the Scion xA – the model the xD replaced – NHTSA gave the old model four out of five stars.
