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

The Lexus GS was redesigned for the 2013 model year. Frontal ratings are assigned by the Institute based on a test conducted by Toyota as part of frontal crash test verification.

Injury measures

Measures taken from the dummy indicate a low risk of any significant injuries in a crash of this severity. Head acceleration from the roof rail hit was low.

Restraints and dummy kinematics

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

Side crash test ratings can be compared across vehicle categories.

The Lexus GS was redesigned for the 2013 model year. Side ratings are assigned by the Institute based on a test conducted by Toyota as part of side crash test verification.

Injury measures

Driver — Measures taken from the dummy indicate a low risk of any significant injuries in a crash of this severity.

Passenger — Measures taken from the dummy indicate a low risk of any significant injuries in a crash of this severity.

Head protection

Driver — The dummy's head was protected from being hit by any hard structures, including the intruding barrier, by a side curtain airbag that deployed from the roof.

Passenger — The dummy's head pushed past the side curtain airbag and was hit by the window sill of the passenger door. This impact did not produce high head injury measures, but the head protection is inadequate.

Roof strength test ratings can be compared across vehicle categories.

In the test, the strength of the roof is determined by pushing a metal plate against one side of it at a slow but constant speed. The force applied relative to the vehicle's weight is known as the strength-to-weight ratio. This graph shows how the ratio varied as the test of this vehicle progressed. The peak strength-to-weight ratio recorded at any time before the roof is crushed 5 inches is the key measurement of roof strength.

A good rating requires a strength-to-weight ratio of at least 4. In other words, the roof must withstand a force of at least 4 times the vehicle's weight before the plate crushes the roof by 5 inches. For an acceptable rating, the minimum required strength-to-weight ratio is 3.25. For a marginal rating, it is 2.5. Anything lower than that is poor.
