Ratings shown are the latest available for this model year.
See below for ratings based on manufacture date.

Check for NHTSA recalls

The photos and videos shown here may be of a different model, model year or body type from the one selected. The ratings of one vehicle often apply to other models if they are built on the same platform. In addition, a test of a vehicle from one model year may apply to earlier or later model years if the vehicle hasn't been significantly redesigned.

Important: Frontal crash test ratings should be compared only among vehicles of similar weight.

This rating applies to vehicles other than the specific model and body style tested.

The Lexus GS was redesigned for the 1998 model year. All 1999 and later GS models manufactured after November 1998 include structural changes to improve occupant protection in frontal crashes. (note: information about when a specific vehicle was manufactured is on the certification label typically affixed to the car on or near the driver door).

The Insurance Institute for Highway Safety has evaluated the crashworthiness of a GS 400 with the structural changes in a 40 mph frontal offset crash test into a deformable barrier.

Injury measures

Measures taken from the head, neck, and chest indicate low risk of injuries to these body regions in a crash of this severity. Forces on the left knee indicate that injuries to the knee would be possible. Head acceleration from roof rail hit was low.

Restraints and dummy kinematics

Dummy movement was well controlled. During rebound, the dummy's head hit the roof rail.
