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

The Kia Optima was redesigned for the 2011 model year.

Structure

The driver space was not maintained well. Lower interior intrusion measured as much as 22 cm at the hinge pillar, and the instrument panel intruded as much as 18 cm. The parking brake pedal was pushed in toward the driver 21 cm.

Injury measures

Measures taken from the dummy indicate a low risk of any significant injuries in a crash of this severity.

Restraints and dummy kinematics

The dummy’s movement was well controlled. The dummy’s head loaded the frontal airbag, which stayed in front of the dummy until rebound. The side curtain airbag deployed but does not have sufficient forward coverage to protect the head from contact with forward side structure and outside objects. The side torso airbag also deployed.

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

The Kia Optima was redesigned for the 2011 model year. Frontal ratings are assigned by the Institute based on a test conducted by Hyundai/Kia as part of frontal crash test verification.

Injury measures

Measures taken from the dummy indicate a low risk of any significant injuries in a crash of this severity.

Restraints and dummy kinematics

Dummy movement was well controlled. The driver side curtain and side thorax airbags deployed during the crash. After the dummy moved forward into the frontal airbag, its head contacted the side curtain airbag.

Injury measures

Driver — Measures taken from the dummy indicate a low risk of any significant injuries 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 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.

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.
