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 as part of frontal crash test verification. 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.
