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 two models, the IS 250 and IS 350, depending on engine size. 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.

Side crash test ratings can be compared across vehicle categories.

The Lexus IS was redesigned for the 2014 model year. There are two models, the IS 250 and IS 350, depending on engine size. 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 was protected from being hit by any hard structures, including the intruding barrier, by a side curtain airbag that deployed from the roof.
