2018 Kia Optima Concord CA

Both the Optima and the Sonata offer similar fuel economy, thanks to the similar 2.4-liter four-cylinder engine for base models. For those looking for the best fuel economy, both models offer a 1.6-liter four-cylinder turbocharged engine option featuring an EPA-estimated 28 city and 37 highway miles per gallon 

While both base models offer a similarly-affordable price tag (the Sonata has a slight edge), the top trim level Optima checks in about $2,000 cheaper than the top-level Sonata. Both are priced affordably for the amount they offer drivers.

In conclusion, both vehicles offer drivers a very similarly-impressive midsize sedan. While the powertrain options and standard and available features are nearly identical on each vehicle, the biggest difference comes down to safety.

While both the 2018 Optima and Sonata boast great safety scores, the Optima comes out just ahead, receiving a perfect score from the National Highway Traffic Safety Administration (NHTSA). Both the Optima and Sonata were awarded Top Safety Pick+ designations from the Insurance Institute For Highway Safety (IIHS).
