Few brands update their model names quite like Kia. And with the new 2025 Kia K4 and K5, our favorite brand brings two modern small and midsized sedans to the mix with similar nomenclature and some shared design choices and tech features, but also several differences you'll want to consider as you shop around Brattleboro, VT and Greenfield, MA. See how these two sedans compare so you can make the best choice, then visit our Keene, NH Kia dealership today.

Choose the Right Kia Sedan for Your Driving Style

Good news! Both of these new Kia sedans are cleverly efficient, making them perfect commuter cars for Brattleboro and Dover, VT drivers. For more power, the new Kia K5 uses a 2.5-liter four-cylinder and pumps out 191 horsepower while earning up to 37 mpg on the highway. The new Kia K4 has a smaller 2.0-liter four-cylinder and only delivers 147 horsepower but also tops out with 40 mpg on the highway. Both sedans also offer performance-minded models with more pop but less in fuel economy.

Pick the Right Cabin Design for Your Kia Sedan

One obvious difference between small and midsized Kia sedans are their sizes. Both seat five, with the small Kia K4 actually offering a bit more rear legroom, but overall, a tighter cabin space than its midsized sibling. The new Kia K5 offers far more total passenger space and a larger trunk, so if you're regularly driving around Keene or Greenfield with passengers, consider the midsized sedan that we have for sale in Keene.

You Can't Go Wrong With a Tech-Filled Kia Sedan

Along with sharp styling, both the new K4 and K5 offer plenty of smart Kia tech features. Easy infotainment controls with plenty of options keep you connected and entertained during your commutes from Keene to Brattleboro, while the latest Kia driver aids are found in the base levels of these sedans, keeping you and your passengers safe while you're on the go.
