The K4 sedan is Kia’s replacement for its long-running Forte model. It’s now available as a sedan and hatchback. While most automakers are switching from compact cars to crossovers, Kia is positioning the K4 as a value-focused alternative to the likes of the Honda Civic, Mazda Mazda3, and Toyota Corolla. Even fully equipped K4 models often cost less than rivals by thousands of dollars, providing a lot of vehicle for the money among compact cars.
Base Price: $28,790
As Tested: $32,870
Horsepower: 190
Mileage: 26 mpg city/33 mpg highway/28 mpg combined
The K4 debuted for 2025 as a sedan, and for 2026, a new hatchback model joins the lineup.
The K4’s styling is bold and modern, but also polarizing as it looks quite different from other compact cars. Kia calls it the “Opposites United” design, with sharp lines, vertical LED lighting and a fastback silhouette. The K4 Hatchback swaps the sedan’s long profile for a shorter, boxier look.
The 2026 K4 sedan comes in five trims: LX, LXS, EX, GT-Line and GT-Line Turbo. Starting prices range from 22,190 to $28,290 which are low for a compact car.
The 2026 K4 Hatchback is not available in the lower trims, only the upper EX, GT-Liine and GT-Line Turbo trims. Starting prices are $24,890, $25,890 and $28,790. While higher than the sedan, these prices are still relatively low for the segment, especially when you consider all of the goodies included in the top trims.
Front-wheel drive is standard on both body styles. All-wheel drive is not available, nor is a hybrid powertrain.
Both the sedan and hatchback have room for five passengers in two rows of seating.
The 2026 K4 is offered with two engines. The four lower trims use a 2.0 liter naturally aspirated four cylinder producing 147 horsepower and 132 pound-feet of torque, paired with a continuously variable transmission. This setup prioritizes smoothness and fuel efficiency. However, acceleration is just ok and drivers may wish for more power when speeding up to merge or pass or when traveling uphill. You’ll want to plan ahead for these situations!
The GT Line Turbo gets a 1.6 liter turbocharged four cylinder producing 190 horsepower and 195 pound-feet, paired to a traditional eight speed automatic transmission. This powertrain delivers noticeably better acceleration, though there is some turbo lag, and more confident highway passing. Steering is light without much feedback. Ride quality remains tuned for comfort rather than sharp handling, meaning the K4 doesn’t have the performance chops of sportier rivals including the Civic and Mazda3.
Fuel economy is decent for a compact car. EPA ratings for the sedan with the base engine are 29 mpg city, 39 mpg highway and 33 mpg combined. The Hatchback with the base engine gets 28 mpg city, 34 mpg highway and 30 combined. Sedans and hatchbacks with the turbo get 26 mpg city, 33 mpg highway and 28 mpg combined. I got 29 mpg with the Hatchback GT-Line Turbo during my week with a mix of city and highway driving.
The interior is one of the nicest in the compact car category. Passenger space is impressive with class-leading rear legroom, with the hatchback adding extra rear headroom. This means adults will be comfortable in both rows. While the sedan doesn’t have as much headroom as the hatchback, it’s still roomy enough for taller adults. Material quality has improved noticeably over the Forte, though some hard plastics remain, as you’d expect at this price point. Even base models come equipped with many features, including a big 12.3-inch infotainment display and digital gauge cluster.
Standard features include remote start, proximity keyless entry, push-button start, cloth upholstery, manually adjustable front seats, four-inch digital gauge cluster, infotainment system with 12.3-inch touchscreen, four-speaker audio system, satellite radio, HD Radio, wireless Android Auto and Apple CarPlay, Bluetooth, four USB ports, and automatic high-beam headlights.
Available features include a digital key, surround-view camera system, dual-zone automatic climate control, synthetic leather upholstery, 10-way power-adjustable driver’s seat, driver’s seat memory settings, heated front seats, ventilated front seats, 60/40 split-folding rear seats, 12.3-inch digital gauge cluster, navigation, six-speaker audio system, eight-speaker Harman Kardon audio system, wireless device charging, ambient interior lighting, and a panoramic sunroof.
Standard driver assistance technologies include forward collision warning, forward automatic emergency braking, stop-and-go adaptive cruise control, lane-departure warning, lane-keep assist, traffic-jam assist (controls braking, acceleration and steering at slow speeds), pedestrian and cyclist detection, traffic-sign recognition, driver-attention monitoring, and rear-seat alert.
Available driver assistance technologies include blind-spot monitoring, blind-spot camera system, evasive steering assist (steers the vehicle to avoid a collision), rear cross-traffic alert, reverse collision warning, reverse automatic emergency braking, front and rear parking sensors, parallel-exit assist (warns of traffic approaching from the rear when exiting a parallel parking spot), and safe exit assist (prevents vehicle doors if another vehicle is approaching from behind).
Cargo space is good for the class. The K4 sedan has 14.6 cubic feet in the trunk; however, the opening is small due to the fastback design. The hatchback has 22.2 cubes behind the second row and 59.3 cubes with the second row folded.
The infotainment system is either the standard 12.3-inch touchscreen or a ginormous 30-inch screen that stretches across the dash. The infotainment system is user-friendly with logically arranged menus, and stays up to date with over-the-air updates. There are toggles for climate settings and a handy menu bar below the touchscreen, so you don’t always have to go through the touchscreen for common functions. The higher trims get Kia’s voice assistant – just say “Hey Kia.”
The good:
Affordable with excellent value for the money
Many standard and available features and tech
Spacious interior with class-leading rear legroom
User-friendly infotainment system
Standard wireless Android Auto and Apple CarPlay
The not-so-good:
Polarizing looks
Lackluster base engine
Rivals have sportier handling
No hybrid or all-wheel drive option
