Whiplash Prevention Crash Test - 2026 SUV Ratings

IIHS is launching this new seat and head restraint evaluation to target neck injuries from rear-end crashes. This 2026 protocol uses separate acceleration pulses to simulate both 20 mph and 30 mph impacts, as many occupants still suffer from whiplash injuries in vehicles previously rated as good.

- Test Speed: The evaluation now includes a high-speed 30 mph pulse to simulate severe real-world crashes.
- Bio-fidelity: A specialized dummy with an articulated spine measures precise stresses on the T1 vertebra.
- New Metrics: Engineers analyze pelvis displacement and the "moment" (tilting force) of the head relative to the neck.

2025-2026 SUV Results:

- GOOD: Audi Q3, Hyundai Ioniq 5, Subaru Forester, Toyota RAV4

- ACCEPTABLE: Buick Encore GX, Chevrolet Equinox, Honda CR-V (2024-25), Jeep Compass, Kia Sportage, Mercedes-Benz GLB-Class, Mitsubishi Outlander, Volkswagen Taos, Volvo XC40

- MARGINAL: BMW X1, Nissan Rogue

- POOR: Ford Bronco Sport, Hyundai Tucson, Mazda CX-50

In Poor-rated vehicles like the Mazda CX-50 and Hyundai Tucson, video footage clearly shows the cervical spine stretching and straightening instead of maintaining its natural curve during the 30 mph impact.

These results are valid only for models sold in the USA
