Moderate overlap front: original test

Rating applies to 2018-24 models

Tested vehicle: 2018 Infiniti Q50 3.0t 4-door

The Infiniti G was redesigned for the 2014 model year and renamed the Q50. Beginning with 2016 Q50 models, the frontal airbags and driver seat belt were modified. Beginning with 2018 models, the steering wheel and driver frontal airbag were further modified to improve occupant protection in small overlap and moderate overlap frontal crashes.

Moderate overlap frontal ratings are assigned by the Institute based on a test conducted by Nissan as part of frontal crash test verification. Because the vehicle structure was unchanged, the structure rating is based on results from this test and two earlier tests of 2014 and 2016 Q50 models conducted by Nissan.

High-beam assist? Yes
Overall rating

Low beams
On the straightaway, visibility was fair on the left side of the road and inadequate on the right side. On curves, visibility was good on both right curves, fair on the sharp left curve and inadequate on the gradual left curve.

The low beams never exceeded glare limits.

High beams
On the straightaway, visibility was good on the right side of the road and inadequate on the left side. On curves, visibility was good on the gradual right curve, fair on the sharp right and gradual left curves, and inadequate on the sharp left curve.

High-beam assist compensates for some limitations of this vehicle's low beams on the straightaway and all 4 curves.
