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

The Lexus IS was redesigned for the 2014 model year. There are various models, depending on engine size and cylinder count. Moderate overlap 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.

Restraints and dummy kinematics

Dummy movement was well controlled. The driver side curtain airbag deployed.

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.

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.

Low beams

On the straightaway, visibility was good on the right side of the road and fair on the left side. On curves, visibility was good on the gradual right curve, fair on the sharp right and sharp left curves, and inadequate on the gradual left curve.

The low beams never exceeded glare limits.

High beams

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