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

The Cadillac STS was introduced in the 2005 model year as a replacement for the Seville.

Injury measures

Measures taken from the neck, chest, and legs indicate low risk of injuries to these body regions in a crash of this severity. A high head acceleration occurred when the dummy's head hit the steering wheel through the airbag, indicating that head injuries would be possible. Head accelerations from the B-pillar, roof rail, and grab handle hit were low.

Restraints and dummy kinematics

Dummy movement was well controlled. During rebound, the dummy's head hit the B-pillar, roof rail, and grab handle.
