The electric motor gets its energy from a 1.5-kWh lithium polymer battery pack in the trunk. You can see the duffle-bag-size battery hump near the front of the trunk. What you can't see is that the Optima's rear seat preserves a small pass-through for long items, like skis.
The dashboard display has a pair of Eco score displays of its own, including this Earth health graphic. As you drive efficiently, you can watch forests grow. Go heavy on the accelerator pedal and watch pollution spread across the globe.
The Optima's cabin is quite comfortable inside and features a variety of materials and textures. Optionally, you can get heated seats at all four seating positions--the driver and front passenger also get cooled seating surfaces--as well as a heated steering wheel.
The Optima's steering wheel features controls for cruise, audio source, and hands-free calling. Additionally, there are buttons for activating the Eco driving mode and toggling the trip computer's screens.
The Optima Hybrid's technology package is otherwise identical to that of the EX trim level that we previously tested. Check out the full review of the 2011 Kia Optima EX for more details and photos of this infotainment system.
