Ratings describe a tested configuration, not the condition or crash history of this individual used vehicle. Compare NHTSA overall and frontal ratings only within the same vehicle class and within 250 pounds of curb weight.
An Autorrive score needs an additional permitted, configuration-matched independent assessment of crash protection, prevention and headlights.
Additional independent testing
IIHS evaluates crash protection, crash prevention and equipment using its own tests and grading system.
A verified independent assessment is not yet included in this report. NHTSA results above remain separate from an Autorrive composite score.
