Three distinct interior themes are available for the Fusion, which seats up to five occupants. Standard equipment includes a tilt/telescoping steering wheel and a height-adjustable driver's seat. A feature unique to Ford in 2008 is an ambient-lighting option that will be offered later in the year: It gives drivers a choice of lighting color for the footwells and cupholder accent lights. Seven colors can be selected with a dashboard switch.

Trunk capacity is 15.8 cubic feet. The rear seats are split 60/40 and fold flat with spring assistance, providing a pass-thru to the trunk. SE and SEL trim levels come standard with a folding front passenger seat.

Optional features include heated front seats, an in-dash six-CD changer and a navigation system that has voice-activation control for 2008. An auxiliary input for MP3 players and the like is standard on all Fusions. Also new for 2008 is Ford's Sync hands-free system, a joint venture with Microsoft that allows drivers to control Bluetooth-enabled mobile phones and MP3 players with steering-wheel buttons and voice commands. Also new, the Reverse Sensing System option uses sonar to beep a warning if an obstacle is in the way when the car is backing up.
