Moderate overlap front

Rating applies to 2019 models

Tested vehicle: 2019 Infiniti QX50 Essential 4-door 4wd

The Infiniti QX50 was redesigned for the 2019 model year after a one-year absence from the market. Moderate overlap frontal ratings are assigned by the Institute based on a test conducted by Nissan as part of frontal crash test verification.

Headlights

Ratings are given for 4 different headlight variations available on this vehicle.

Trim level(s)

  • Essential trim equipped with Proactive package
Low-beam headlight type LED projector
High-beam headlight type LED reflector
Curve-adaptive? No
High-beam assist? Yes
Overall rating
Distance at which headlights provide at least 5 lux illumination:
car-simpler car-simpler car-simpler car-simpler car-simpler 0 ft 100 ft 200 ft 300 ft 400 ft 500 ft 600 ft Low beams Optimal low-beam illumination High beams Optimal high-beam illumination High-beam assist credit

Low beams
On the straightaway, visibility was fair on both sides of the road. On curves, visibility was inadequate in all 4 tests.

The low beams never exceeded glare limits.

High beams
On the straightaway, visibility was good on both sides of the road. On curves, visibility was fair on both right curves and inadequate on both left curves.

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