2015 KIA Optima – Driving Video

The 2015 Optima features a uniquely engineered body that combines various high-tensile strength steel alloys and sits on a chassis that is stiffer and more durable thanks to the increased use of Advanced High Strength Steel (AHSS). With more than 50 percent of the body constructed from AHSS, the all-new Optima represents a 150-percent increase over the previous car. The greater use of structural adhesive by more than 450 percent over the previous generation improves NVH and contributes to structural rigidity. Engineers also added more hot stamped components to the all-new Optima, a 350-percent increase over the 2015 model. This body structure helps provide crash protection, better driving dynamics, and is the foundation for a quieter ride.
