Tested vehicle: 2023 Infiniti QX55 Luxe 4-door 4wd
Rating applies to 2023-25 models
The Infiniti QX55 was introduced in the 2022 model year. Beginning with 2023 models, structural changes were implemented to improve occupant protection in side impact crashes. Side ratings are assigned by the Institute based on a test of a 2023 QX55 conducted by Nissan.
