Moderate overlap front: original test
Tested vehicle: 1999 Hyundai Sonata 4-door
Rating applies to 2001-06 models built before October 2005
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.

| Rear passenger head protection 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. |
