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.
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.
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.
