Used 2015 Kia Optima Hybrid Review

EPA fuel economy estimates differ slightly between the two trim levels, with the base earning a combined estimate of 38 mpg (36 city/40 highway) and the EX rating 37 mpg combined (35/39). Although those numbers are generally impressive, the Optima Hybrid's rivals are even more frugal.

In Edmunds performance testing, a Kia Optima Hybrid went from zero to 60 mph in 8.7 seconds, which is a bit below average for the segment.

Standard safety features on the 2015 Kia Optima Hybrid include four-wheel antilock disc brakes, traction and stability control, side airbags and side curtain airbags. A rearview camera is available, as are rear parking sensors, rear cross-traffic alert and a blind-spot monitoring system. The available Uvo telematics system includes roadside assistance and automatic collision notification.

In Edmunds brake testing, an Optima Hybrid EX came to a stop from 60 mph in 129 feet, a few feet longer than average but still acceptable for this class.

In government crash tests, the Optima Hybrid earned a top five-star rating for overall crash protection, with five stars awarded for both total frontal-impact safety and total side-impact safety. The Insurance Institute for Highway Safety gave the non-hybrid but otherwise identical Optima a top score of "Good" in its moderate-overlap frontal-offset, side-impact and roof-strength impact tests. The Optima earned an "Acceptable" rating (second highest) in the small-overlap frontal-offset crash test, while its seat and head restraint design was rated "Good" for whiplash protection in rear impacts.

First impressions of the 2015 Kia Optima's interior are usually favorable. There's a distinctly modern look to the design, and the sense of quality is boosted by an abundance of soft-touch materials. The EX trim level pours on the charm with its additional equipment and leather upholstery. If you're looking for a touch of luxury in your hybrid sedan, the Optima Hybrid is a top choice.

Kia's Uvo (pronounced "yoo-voh") electronics interface system is similar to Ford's Sync system (both are powered by Microsoft). Uvo provides voice controls for connected phones and other devices, as well as services such as points of interest and turn-by-turn navigation. In our testing of Uvo, we've found that it works quite well. The touchscreen interface in navigation-equipped Optima Hybrids features high-resolution graphics that are among the segment's best, and it's easy to use, too.

The Optima Hybrid has a fairly spacious cabin, with comfortable seats and adequate legroom front and rear. However, headroom in back is a bit tight due to the car's rakish, coupelike roof line. Opting for the panoramic sunroof further decreases headroom. The Optima Hybrid's trunk offers 10.8 cubic feet of cargo space, considerably less than the non-hybrid Optima due to intrusion from the hybrid battery pack, and 1-2 cubes less than the competition.

The 2015 Kia Optima Hybrid rides smoothly on a variety of surfaces, and its cabin remains admirably hushed at highway speeds. The car's steering is less praiseworthy, though, thanks to a numb feel and artificially high effort. Nonetheless, the driving experience is pleasant overall, with a good balance between handling agility and ride comfort.

Most drivers should be satisfied with the Optima Hybrid's performance. You'll scarcely notice the transitions between gas and electric propulsion in traffic, and there's more power for passing maneuvers than the mediocre 0-60-mph sprint suggests. The only real issue on the road is the odd braking response, which stems from the car's hybrid regenerative braking system. There's a small but noticeable delay between pressing the brake pedal and actually getting the desired braking force. Make no mistake, the 2015 Optima Hybrid provides plenty of braking power when you need it, but it's a peculiarity that will likely require acclimation.
