Important: Frontal crash test ratings should be compared only among vehicles of similar weight.

The Infiniti FX was redesigned for the 2009 model year. There were two models, the FX35 (equipped with a V6 engine) and the FX50 (equipped with a V8 engine). The FX was renamed the QX70 beginning with the 2014 model year. Frontal ratings are assigned by the Institute based on a test conducted by Nissan as part of frontal crash test verification.
