Test details:

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

Restraints/dummy kinematics — Dummy movement was well controlled. During rebound, the dummy’s head hit the B-pillar, roof rail, and grab handle.

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.

  • Action shot taken during the frontal offset crash test.
  • The dummy's position in relation to the steering wheel and instrument panel after the crash test indicates that the driver's survival space was maintained very well.
  • Smeared greasepaint indicates where the dummy’s head hit the B-pillar, roof rail, grab handle, and head restraint. Head accelerations from these hits were low.
  • Intrusion into the driver's space was minimal, and all leg and foot injury measures were low.

Additional features:

  • Side airbags: front and rear head curtain airbags and front seat-mounted torso airbags
  • Electronic stability control
