Only Four Small SUVs Pass Tougher IIHS Rear-Crash Safety Test in 2026
The Insurance Institute for Highway Safety (IIHS) has rolled out a stricter test for seat and head restraint safety in rear-end crashes. Out of 18 small SUVs evaluated, only four models earned a 'good' rating under the new system. The updated assessment aims to reduce whiplash injuries by simulating higher-speed impacts and measuring key risk factors.
The new test replaces an older method with a less destructive but more precise simulation. Instead of crashing entire vehicles, the driver seat is mounted on a sled to replicate a rear impact. Evaluators then examine three critical areas: head and spine support, how the head restraint interacts with the occupant, and how the seat absorbs energy.
To better predict real-world injuries, the test now includes metrics like pelvis displacement. This helps assess how well seats protect passengers at higher speeds, where injury risks increase. The IIHS hopes these changes will push manufacturers to improve designs and lower insurance claim rates.
Among the 18 small SUVs tested, the Audi Q3, Hyundai Ioniq 5, Subaru Forester, and Toyota RAV4 were the only models to achieve a 'good' rating. Nine others—including the Buick Encore GX, Chevrolet Equinox, and Volvo XC40—received 'acceptable' scores. The BMW X1 and Nissan Rogue were rated 'marginal', while the Ford Bronco Sport, Hyundai Tucson, and Mazda CX-50 fell into the 'poor' category.
The Subaru Crosstrek and Subaru WRX performed worst in the latest 2026 evaluations. Issues included poor seatbelt positioning, which shifted to the abdomen, along with only acceptable chest protection and marginal control over passenger movement during impacts.
The updated IIHS test highlights gaps in rear-crash protection across many small SUVs. With only four models meeting the highest standard, automakers may need to revise seat and restraint designs. The results also provide clearer data for consumers comparing safety features in this popular vehicle category.
