Moderate overlap front: original test
Rating applies to 2022-24 models
Tested vehicle: 2021 Infiniti QX50 Essential 4-door 4wd
The Infiniti QX50 was redesigned for the 2019 model year after a one-year absence from the market. Beginning with 2021 models, design changes were made to the front driver and passenger seat belts and passenger-side frontal and knee airbags to improve occupant protection in frontal crashes.
Moderate overlap frontal ratings are assigned by the Institute based on a test of a 2021 QX50 conducted by Nissan. Because the structure was not changed, the structure rating is based on this verification test and an earlier test of a 2019 QX50 conducted by Nissan.
These ratings also apply to the structurally similar Infiniti QX55, introduced in the 2022 model year.
