2006 Kia Optima

Tested vehicle: 2006 Kia Optima LX 4-door
Rating applies to 2006-10 models built after September 2005

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.

About the original moderate overlap front 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.

About the original moderate overlap front test

Tested vehicle: 2008 Kia Optima LX 4-door with standard front and rear head curtain airbags and standard front seat-mounted torso airbags
Rating applies to 2006-10 models built after June 2006

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).
