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

The Kia Optima was redesigned during the 2006 model year. It no longer shares its body structure with the Hyundai Sonata, which was also redesigned for 2006.

All 2006-10 manufactured after September 2005 are redesigned (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). 2006 Optima models manufactured in Sept. 2005 or earlier share the previous design with 2001-05 models.

Injury measures

Measures taken from the head, neck, and chest indicate low risk of injuries to these body regions in a crash of this severity. Forces on the right tibia indicate that injuries to the lower leg would be possible. Head acceleration from the roof rail hit was low.

Restraints and dummy kinematics

Dummy movement was well controlled. During rebound, the dummy's head hit the roof rail.

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

The 2006 Kia Optima is a twin of the tested vehicle.

The Hyundai Sonata was redesigned for the 1999 model year, and the Kia Optima was introduced in the 2001 model year. The Sonata was again redesigned for 2006, but the Kia Optima remained unchanged for the early part of the 2006 model year (2006 cars manufactured before October 2005). Therefore the ratings listed here also apply to early 2006 Optimas.

Injury measures

Measures taken from the head, neck, and chest indicate low risk of injuries to these body regions in a crash of this severity. Forces on both tibias indicate that injuries to the lower legs would be possible. 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 and roof rail.

Side crash test ratings can be compared across vehicle categories.

The Kia Optima was redesigned during the 2006 model year. It no longer shares its body structure with the Hyundai Sonata, which was also redesigned for 2006.

Beginning with 2006 models manufactured after June 2006, design changes were made to the rear door structure and trim 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).

Injury measures

Driver — Measures taken from the dummy indicate that a fracture of the pelvis would be possible in a crash of this severity. The risk of significant injuries to other body regions is low.

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.

Injury measures

Driver — Measures taken from the dummy indicate that rib fractures and/or internal organ injuries plus a fracture of the pelvis would be likely 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 airbag that deployed from the seat.

Passenger — The dummy's head was hit by the pillar behind the rear passenger door and the window sill of the rear door. This pillar is required by federal standard to provide some protection for occupants' heads. The hit by the window sill did not produce high head injury measures, but the head protection is inadequate.

Roof strength test ratings can be compared across vehicle categories.

In the test, the strength of the roof is determined by pushing a metal plate against one side of it at a slow but constant speed. The force applied relative to the vehicle's weight is known as the strength-to-weight ratio. This graph shows how the ratio varied as the test of this vehicle progressed. The peak strength-to-weight ratio recorded at any time before the roof is crushed 5 inches is the key measurement of roof strength.

A good rating requires a strength-to-weight ratio of at least 4. In other words, the roof must withstand a force of at least 4 times the vehicle's weight before the plate crushes the roof by 5 inches. For an acceptable rating, the minimum required strength-to-weight ratio is 3.25. For a marginal rating, it is 2.5. Anything lower than that is poor.
