Action shot taken during the small overlap frontal crash test.

The dummy's position in relation to the door frame, steering wheel, and instrument panel after the crash test indicates that the driver's survival space was maintained well.

The frontal and side curtain airbags worked well together to keep the head from coming close to any stiff structure or outside objects that could cause injury.

The driver's space was maintained well, and risk of injuries to the dummy's legs and feet was low.

How the driver-side small overlap front test is conducted

Small overlap front: passenger-side

Rating applies to 2020-22 models

Tested vehicle: 2020 Lexus RX 350 4-door 4wd

The Lexus RX was redesigned for the 2016 model year. Beginning with the 2020 model year, the bumper and front-end structure were reinforced on the passenger side to improve occupant protection in passenger-side small overlap frontal crashes. Passenger-side small overlap ratings are assigned by the Institute based on a test conducted by Toyota as part of frontal crash test verification.

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

The low beams never exceeded glare limits.

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

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