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

The Lexus IS was introduced in the 2001 model year and structurally modified beginning with 2002 models to improve occupant protection in frontal offset crashes.

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 B-pillar hit was low.

Restraints and dummy kinematics

Dummy movement was well controlled. During rebound, the dummy's head hit the B-pillar.
