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

The Hyundai Sonata was redesigned for the 2011 model year. Hyundai subsequently made several modificatons to the front structure of the car since its introduction in early 2010, with the final change effective as of September 2010. Moderate overlap frontal tests conducted before and after the changes did not substantially affect the ratings, and Hyundai has stated the same is true for small overlap frontal tests, in which much of the front structure is bypassed by crash forces.

Structure

The driver space was not maintained well. Lower interior intrusion measured as much as 24 cm at the hinge pillar, and the upper hinge pillar and instrument panel intruded 15-18 cm. The parking brake pedal was pushed back 28 cm toward the driver.

Injury measures

Measures from the dummy indicate that injuries to the left lower leg would be possible in a crash of this severity. The risk of significant injuries to other body regions is low.

Restraints and dummy kinematics

The dummy’s head contacted the frontal airbag but slid off the left side, leaving the head vulnerable to contact with forward side structure. The side curtain airbag did not deploy, also leaving the dummy’s head vulnerable to contact with side structure and outside objects.

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

The Hyundai Sonata was redesigned for the 2011 model year. Hyundai subsequently made several modificatons to the front structure of the car since its introduction in early 2010, with the final change effective as of September 2010. Frontal ratings are assigned by the Institute based on two tests conducted by Hyundai as part of frontal crash test verification, before and after all structural changes were made. Because the frontal ratings were not substantially affected by the changes, the ratings are based on both tests.

Injury measures

In both tests, 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 in both tests. The driver side curtain and side thorax airbags deployed during the crashes. 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.
