2018 Honda Accord vs 2018 Kia Optima

Proudly Serving Highland, IN

For decades, the Honda Accord has arguably been the top midsize sedan around because of its perennial ability to prove itself as an all-rounder. Whether you want something that’s fun to drive or your needs are more practical, the Accord is the ideal vehicle to get; it appeals to a wider range of customers than most midsize sedans. And that doesn’t seem to change with the 2018 model year, which finds the longstanding stalwart in its tenth generation. Among its most formidable challengers is the Kia Optima, which has been around since 2000 and is currently in its fourth generation. The Optima has a lot to recommend it: attractive styling, fun-to-drive personality, and a host of hi-tech features. But overall, it falls short of the Honda Accord’s lofty status. Here’s why:

Fuel Economy

In its attempt to make its perennial best-seller more fuel-efficient than ever before, Honda introduces a pair of engines on the 2018 Accord, none of which are beefy V6s. The smaller of the two, which is the L15B7, is a turbocharged 1.5-liter inline 4-cylinder (I4) engine. Small and thus not a gas guzzler, the L15B7 can be joined with a continuously variable transmission—which does its part by eschewing the energy-consuming gear-shifting mechanism found on traditional gearboxes—to maximize the Accord’s fuel efficiency to 30 mpg in the city and 38 mpg on the highway. Also with a pair of engine choices, the 2018 Kia Optima has a turbocharged 1.6-liter I4 (Gamma G4FJ) as the more fuel-efficient of the two. It is joined with a 7-speed dual-clutch transmission (DCT), which also helps with a high level of gas mileage because it has two separate clutches instead of one. However, the Gamma engine is slightly larger than the L15B7 (thus needing more fuel), and the DCT is not as energy-efficient as the CVT. As a result, the Optima peaks at 28/37 mpg with this configuration. That’s 2 less mpg in the city and 1 less mpg on the highway.

Engine Power

For that extra kick, you can go with the K20, which is a turbocharged 2.0-liter inline 4-cylinder (I4) engine that pumps out 252 horsepower and 273 lb-ft of torque. The K20 is available on the Sport, EX-L, and Touring. The 2018 Kia Optima also relies on a 2.0-liter turbocharged I4 for maximum power in the form of the Theta II engine. However, the Theta II generates 245 horsepower and 260 lb-ft of torque; that’s 7 less horsepower and 13 less lb-ft of torque than the Honda’s K20.

Overall Value

In its evaluation and aggregation of professional reviews and rankings—taking into account a multitude of factors—the U.S. News & World Report ranks the 2018 Honda Accord at #2 in the Midsize Cars category. The publication cites great gas mileage, a spacious cabin, engaged handling, and loads of standard driver-assistance technologies among its major attributes. By comparison, in the same category, the 2018 Kia Optima placed #6.
