2017 Hyundai Sonata vs Kia Optima

Creature Comforts

The Sonata puts your comfort first, with roomy, supportive seats and a smooth ride. It also just might be the quietest in its class, providing the kind of serene highway ride that you’d expect from a luxury car. Inside, the Sonata’s plush seats are perfect for commuters. They’re exactly where you want to be if rush-hour traffic can’t be avoided. You’ll also like its roomy trunk, with 16.3 cubic feet for major grocery hauls and sporting goods.

In the Kia Optima, you’ll find decent seating comfort for long trips. However, the lack of lateral support might be a deal-breaker for some. The drive isn’t quite as smooth as what you’ll find in the Sonata, but you can count on the Optima for a quiet ride.

Tech Features

The Sonata’s tech features are very user-friendly. Even if you’ve never dealt with infotainment technology before, you’ll have things sorted out in no time. Apple CarPlay and Android Auto connectivity display smartphone apps on the central touchscreen, so there’s no need to look down at your phone. You can even use Siri or Google voice controls to ask the system to reroute your Maps destination or read your texts.

The Optima also offers Apple CarPlay and Android Auto, giving you complete smartphone integration. If we had to choose, though, the Sonata’s Blue Link technology feels more intuitive than the Optima’s Uvo system. That said, once you get over the learning curve, you’ll enjoy easy access to apps like navigation.


In government crash tests, the Sonata scored a perfect five stars for overall protection. And, if that’s not enough to put your mind at ease, you’ll love its automatic forward collision emergency braking feature. When it senses an oncoming crash, it jumps into action to help keep you safe. All models come standard with Blue Link emergency telematics, which includes problem-solving features like roadside assistance and crash response.

The Optima also earned shining crash-test scores. It doesn’t come standard with emergency telematics features, but you can add all the same driver aids that are available on the Sonata. Lane departure warning, for example, lets you know if you need to correct your course.

Power & Performance

The Optima impresses with its swift ride and modern fuel economy. Depending on powertrain, this sedan earns up to 28 city/37 highway mpg. We’re also fans of the way it handles – you’ll be swinging around corners and down winding roads with the best of them.

The 2017 Hyundai Sonata follows close behind with up to 28/36 mpg. And, as we mentioned, it provides one of the most refined rides in this segment. At the wheel, the responsive steering boosts your confidence, especially when road conditions are less than ideal.
