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.

Side crash test ratings can be compared across vehicle categories.

The Cadillac STS was introduced in the 2005 model year as a replacement for the Seville. Beginning with 2007 models built after August 2006, the B-pillars were reinforced and the front door trim panels and side torso airbags were changed to improve occupant protection in side-impact crashes (note: information about when a specific vehicle was manufactured is on the certification label typically affixed to the car on or near the driver door). The tested car was manufactured after the modifications had been made.

Injury measures

Driver — Measures taken from the dummy indicate that a fracture of the pelvis would be likely in a crash of this severity. Rib fractures and/or internal organ injuries would also be possible.

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 and a side airbag that deployed from the seat.

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.
