The style makeover continues into the Optima's cabin with expanded electronics melded with refreshed fascia patterns and color schemes. Based on a new platform, the standard audio system features MP3 compatibility, a USB port and SIRIUS satellite radio capability in addition to an auxiliary jack, which was added to 2008 models. An optional in-dash navigation system also is an Optima first.

The rest of the center fascia and floor console receive minor tuning for even more intuitive operation whereas the new barrel-type instrument cluster design adopts a sporty red illumination. Optima continues to offer two seat trims in gray or beige color schemes - cloth (LX), leather (EX) - with black leather trim on SX models, which also features aluminum trim, metal sport pedals and a Supervision meter cluster.

Amidst the host of additional options, Optima still offers an array of standard features. The LX is equipped with air conditioning, power windows and door locks, an AM/FM/CD audio system with six speakers, cloth seat and door trim, a six-way adjustable driver's seat and four-way adjustable front passenger seat as well as 60/40-split folding rear seats. EX models upgrade to a leather-wrapped steering wheel with tilt and telescopic functions, leather seat and door trim, leather-wrapped shift knob, automatic temperature control, an auto-dimming rearview mirror featuring Homelink® and an eight-way power adjustable driver's seat. Convenience and Premium Packages offer further content upgrades, including a power sunroof and an Infinity® audio system.
