Hyundai Sonata vs Kia Optima

It's hard to find two midsize sedans as similar as the 2019 Hyundai Sonata and Kia Optima. These two cars are a sure way to get noticed as you cruise the coastal roads of Hardeeville, Bluffton, and Hilton Head Island.

In this car comparison, our team at Peacock Hyundai Hilton Head wants to show you how these corporate cousins measure up! They're identical in many ways, but you'll find some significant differences between the two. Read on and discover the best fit for you.

Sonata vs Optima: Performance Specs

The 2019 Sonata and Optima use the same powertrains. Standard in both is a 2.4L 4-cylinder engine (185 horsepower), while a 2.0L turbo 4-cylinder (245 horsepower) is available. The base engines are potent daily drivers, while the turbo engines deliver on thrills.

You might expect the fuel economy figures to be the same, but the Hyundai sedan has a slight advantage. Its turbo engine achieves an EPA-estimated 23 city/32 highway MPG.1 The same engine in the Optima, though, clocks in with an EPA-estimated 21 city/30 highway MPG.

Both vehicles deliver smooth, robust rides, but you'll go a bit further on less fuel with the Sonata at your command.

Interior Features: Cabin Specifications

Slide into the Hyundai Sonata and Kia Optima, and you may never want to leave! Tall drivers will find these cars a welcome respite, with 45.5 inches of front-row legroom each. Even the backseats are adult-friendly, with 35.6 inches of legroom.

Plus, with available leather upholstery and heated/cooled front seats, you're in for a satisfying experience behind the wheel. Quality materials abound in both midsize cars.

Trunk space is roomy in these vehicles, though the Sonata has a slight advantage. With 16.3 cubic feet of cargo volume, you can pack up your groceries, golf clubs, and much more. The Optima's trunk is nearly as spacious with 15.9 cubic feet. Split-folding rear seats are standard in both cars.

Exterior Flare: Sedan Style & Design

With two such similar sedans, the easiest way to tell them apart might be exterior style. The 2019 Sonata and Optima are both modern vehicles with all the cutting-edge features you'd expect. All lights, from the headlamps and taillamps to the daytime running lights, are available with efficient LED bulbs.

Hyundai has been on a design streak as of late, and the Sonata is an excellent example of this. A fastback roofline, bold hexagonal grille, and unique fog lights help it stand out from the crowd.

The Optima shares a fastback roof with its Hyundai counterpart. However, its smaller, shorter grille just doesn't quite exude the same level of style or dynamism as the Sonata.
