Small overlap front

The small overlap front evaluation consists of a driver-side and a passenger-side component. If the results of the two evaluations differ, then the combined small overlap rating is equal to the lower rating.

Driver-side

Rating applies to 2019-25 models

Tested vehicle: 2019 Lexus UX 250h 4-door 4wd

The Lexus UX was introduced in the 2019 model year. Driver-side small overlap frontal ratings are assigned by the Institute based on a test conducted by Toyota.

Rear passenger restraints and dummy kinematics

View of the vehicle after the crash showing the airbags and damage to the occupant compartment.

The rear passenger dummy's head came close to contacting the front seatback, which increases the risk of head injuries.

Rear passenger dummy injury values indicate a low risk of injury to the head or neck and chest. During the crash, the shoulder belt moved too far upward toward the dummy’s neck, compromising the effectiveness of the rear restraint system.

The rear passenger dummy's lap belt moved from the ideal position on the pelvis onto the abdomen, increasing the risk of abdominal injuries.

Low-beam headlight type	LED projector
High-beam headlight type	LED projector
Curve-adaptive?	No
High-beam assist?	Yes
Overall rating
Distance at which headlights provide at least 5 lux illumination:

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

High-beam assist compensates for some limitations of this vehicle's low beams on both left curves and on both right curves.
