Rollover evaluations

Small pickups

To measure roof strength, a metal plate is pushed against one corner of a vehicle's roof at a constant speed. The maximum force sustained by the roof before 5 inches of crush is compared to the vehicle's weight to find the strength-to-weight ratio. This is a good assessment of vehicle structural protection in rollover crashes.

Each model is rated based on our measured curb weight of a vehicle with typical engine, transmission, and equipment options. However, when the same model is available in a configuration over 10% heavier than the typically equipped vehicle, a separate rating is assigned.
