2018 Hyundai Sonata vs 2018 Kia Optima

Despite the success of the crossover and SUV markets, midsize sedans are far from dead. In fact, they seem to have become increasingly sophisticated and performance-driven over the years. The Hyundai Sonata is a great example of that. But to help you determine if the vehicle is right for you, we're comparing the 2018 Hyundai Sonata vs the 2018 Kia Optima, another top contender in the class. Use the chart down below to get a side-by-side comparison, and then keep reading to learn more. When you're ready, get in touch with us at Coastal Hyundai or explore our available inventory.

Sonata vs Optima Value Comparison

You'll find that many things are similar between these two vehicles. Even engine power is identical, and this comes as no surprise considering the fact that Kia is owned, in part, by Hyundai Motor Group. Even the prices are pretty close.

That being said, the 2018 Sonata does have a slightly lower starting MSRP, and for that lower price, it actually comes with some standard features that the Optima does not. These include a total of three 12-volt DC power outlets, cargo tie downs, driver's side 1-touch window down function, daytime running lights and Lane Departure Warning. That's on top of the Sonata's superior cargo and passenger space.

Hyundai vs Kia Warranties

Hyundai frequently puts other brands to shame when it comes time to comparing the warranty between the two. In this case, Kia actually has similar warranties when it comes to the term length for each one. There is a difference to be found, however, and it is with the Anti-Perforation Warranty. While Kia has a 5 year Anti-Perforation Warranty with just 100,000 miles, Hyundai provides Sonata owners with 7 years and unlimited miles.

There is so much more you could learn comparing the 2018 Hyundai Sonata vs the 2018 Kia Optima. To do so, or to simply get behind the wheel, contact us at Coastal Hyundai. Either way, it seems clear that the Sonata has an edge in critical areas.
