Quick Answer
For most commuters and small families, the Kia K4 is the right Kia sedan: it brings a modern, tech-forward cabin, more interior space than many competitors, and available turbo power of up to ~190 horsepower at a great value. If you want a sportier drive, the Kia K5 steps up with up to ~290 horsepower in K5 GT form and available all-wheel drive, which our Racine customers appreciate every Wisconsin winter.
Shopping for value? A pre-owned Kia Stinger (performance), Forte (reliability and efficiency), or Rio (fuel economy and easy city driving) gives you a lot of car for the money, especially through Kia’s Certified Pre-Owned program.
Choosing the right sedan can feel overwhelming these days, especially with so many great options on the market. But when customers stop by Frank Boucher Kia of Racine in Racine, WI, the conversation usually becomes much easier once they take a closer look at the Kia sedan models available. Kia has built a reputation for crafting sedans that balance style, performance, technology, and everyday practicality – without forcing drivers to stretch their budget. Whether someone’s looking for something sporty, something efficient, or something that simply makes the daily commute more enjoyable, there’s a Kia sedan that fits the bill.
Kia’s current lineup includes two standout new Kia sedan options – the Kia K4 and Kia K5 – along with several popular pre-owned choices like the Stinger, Forte, and Rio. Since there’s no Kia Rio, shoppers looking for that model will find it in the pre-owned or certified pre-owned inventory. Each sedan brings its own personality to the road, and understanding those differences can make the decision much easier.
