The 2017 Kia Optima remains a strong contender in the midsize sedan segment, offering a roomy cabin, a large trunk, and compelling value for buyers. Following a full redesign in 2016, changes for 2017 were minor, including upgraded LED headlights on higher trims and the introduction of new packages such as the LX Driver Convenience and EX Premium Plus.
The Optima continues to appeal to families and value-conscious buyers with its balance of practicality, comfort, and a relatively upscale interior without the premium price of luxury sedans. Its sleek roofline, while visually attractive, reduces rear headroom and slightly impacts rear visibility, which is a minor compromise in an otherwise well-rounded package.
The Optima’s performance varies depending on the engine choice. The base 1.6-liter turbocharged engine paired with a seven-speed dual-clutch automatic can feel hesitant, especially at low speeds, with a 0-60 mph sprint of 7.7 seconds.
In contrast, the more powerful 2.0-liter turbo in SX trims accelerates more briskly at 6.7 seconds. Steering is predictable but offers minimal feedback, and braking can feel grabby with a soft pedal. Handling remains competent for its class, with the car cornering predictably despite narrow tires.
The 1.6T transmission is jumpy at low speeds, making drivability less smooth, whereas the 2.0T with a conventional automatic delivers more natural gear shifts. The Optima is comfortable for everyday driving, though it is less engaging than some competitors for those seeking a sportier experience.
Inside, the 2017 Optima emphasizes functionality and comfort. Front seats provide ample space and adjustment options, though lateral support is limited. Rear seats are roomy for legroom but have slightly constrained headroom due to the sloping roofline.
Ride quality is smooth over small bumps, with some jostling over larger undulations, while road and wind noise remain subdued. The cabin is practical and well-designed, with logically placed controls and solid, attractively grained plastics.
Storage is plentiful, including a 15.8-cubic-foot trunk with remote seatback releases, multiple small-item compartments, and an automatic trunk opener for key fob users. LATCH anchors for child safety seats are easily accessible, adding to the Optima’s family-friendly appeal.
Technology in the 2017 Optima is user-friendly and functional. The 8-inch Uvo touchscreen features bright graphics and physical buttons for easy operation, while upper trims offer a 10-speaker Harman Kardon audio system.
Android Auto and Apple CarPlay are available, improving smartphone integration, though some menu options are less intuitive. Voice controls are effective for navigation and phone commands, with Siri and Google Assistant improving accuracy.
Advanced driver aids, including blind-spot monitoring, rear parking sensors, and rear cross-traffic alert, are available even on lower trims, enhancing safety.
While not a perfect vehicle, the 2017 Kia Optima provides a practical, comfortable, and tech-rich midsize sedan experience at a competitive price, making it a sensible choice for families and everyday commuters alike.
5. 2010 Kia Optima
The 2010 Kia Optima targets shoppers who prioritize affordability and practicality over chasing popular best-sellers like the Toyota Camry or Nissan Altima. Offering a roomy interior at a lower price point, the Optima often costs less than some well-equipped compact cars, making it attractive to budget-conscious buyers.
However, this affordability comes with trade-offs. Ride comfort is not as refined as class leaders, and the optional V6 produces less than 200 horsepower in a segment where competitors boast upwards of 250.
Interior quality also feels less upscale compared to rivals. Still, for shoppers seeking maximum features at minimal cost, a fully loaded Optima can be purchased for thousands less than comparably equipped competitors, giving it strong appeal in the value market.
Performance is modest, with two available engines. The standard 2.4-liter four-cylinder generates 175 horsepower and delivers competitive fuel economy at 22 mpg city/32 mpg highway. A five-speed manual is standard on the LX trim, while other models come with a five-speed automatic.
The optional 2.7-liter V6 produces 194 horsepower and 184 lb-ft of torque but falls short of rivals in acceleration, with fuel economy rated at 20 mpg city/28 mpg highway. On the road, the V6 provides sufficient power for daily use but struggles during high-speed merging and passing.
Ride quality is serviceable, though somewhat brittle compared to smoother competitors like the Honda Accord. The sportier SX trim improves handling slightly, but the Optima remains far from a true sport sedan. Most buyers will find the four-cylinder to be the better choice for its balance of efficiency and usability.
In terms of safety, the 2010 Kia Optima performs impressively for its class and price point. Standard safety features include antilock brakes, stability control, front-seat side airbags, full-length side curtain airbags, and active front head restraints. In government crash testing, the Optima earned five stars in both front and side impact categories.
Additionally, the Insurance Institute for Highway Safety awarded it the highest “Good” rating in frontal-offset tests and an “Acceptable” in side-impact evaluations. These strong scores bolster its reputation as a family-friendly sedan.
While not the most exciting option in the midsize category, its solid safety credentials and reliability make it a smart, confidence-inspiring choice for buyers prioritizing long-term dependability.
Inside, the Optima emphasizes function over flash. The dashboard design is clean, uncluttered, and easy to use, which some buyers may find preferable to the button-heavy setups in rivals.
Cabin space is generous, providing good comfort for front and rear passengers, though rear seat cushions are shorter and may feel unsupportive for taller adults on longer trips. Cargo space is competitive at 15 cubic feet, and all trims feature 60/40-split-folding seatbacks to increase versatility.
While material quality is below class standards, build quality feels solid for the price. The 2010 Kia Optima delivers affordability, safety, and practicality, making it a rational if modest alternative in the crowded midsize sedan market.
