The 2025 Kia K4 comes in five trims. Each one adds different features at different price points. This guide breaks down what you get with each trim so you can pick the right one.
The K4 starts with the LX base model and goes up to the GT-Line Turbo Limited. Each step up brings more tech, comfort, or power.
Two Engines Power the K4 Lineup
The first three trims (LX, EX, EX+) use a 2.0-litre engine. It makes 147 horsepower and gets good gas mileage. This engine works with a CVT transmission that keeps fuel costs low.
The GT-Line models get a 1.6-litre turbo engine. This one makes 190 horsepower - that's 43 more than the base engine. It comes with an 8-speed automatic transmission.
Both engines run on regular gas, so you won't pay extra at the pump. The base engine focuses on daily driving efficiency, while the turbo gives you quick acceleration for highway merging and passing.
Engine Facts:
- Base 2.0L: 147 hp, 132 lb-ft torque
- Turbo 1.6L: 190 hp, 195 lb-ft torque
- All models are front-wheel drive
- Both engines use regular gas
- CVT for base engine, 8-speed auto for turbo
Fuel Economy Numbers
The LX gets the best fuel economy at 7.0L/100km combined. The EX and EX+ use a bit more at 7.3L/100km because they're heavier with more features.
The GT-Line turbo models use 8.0L/100km combined. That's still good for a turbo engine with 190 horsepower.
Highway driving brings out the best efficiency in all trims. The base engine excels at steady speeds, while the turbo engine delivers power when you need it and efficiency when you don't.
Fuel Use:
- LX: 7.9 city / 5.8 highway / 7.0 combined L/100km
- EX/EX+: 8.4 city / 6.0 highway / 7.3 combined L/100km
- GT-Line: 9.2 city / 6.6 highway / 8.0 combined L/100km
- All trims have a 47-litre fuel tank
- Highway driving saves the most gas
Interior Space
The K4 has more room inside than most compact cars. Front seat passengers get 1,074mm of leg room. Back seat riders get 964mm - enough space for adults on long trips.
Higher trims add heated seats and dual-zone climate control. The top GT-Line Limited has cooled front seats and memory settings for the driver's seat.
The long wheelbase creates this extra space without making the car too big for city parking. You get midsize comfort in a compact footprint that still fits in tight spots.
Space Details:
- Total passenger volume: 2,794 litres
- Front leg room: 1,074mm
- Rear leg room: 964mm
- Front head room: 990mm (947mm with sunroof)
- Rear head room: 942mm (940mm with sunroof)
Cargo Space
The trunk holds 413 litres. That's enough for a week's groceries or several suitcases. The opening is wide and the floor is low, making it easy to load heavy items.
The rear seats fold down 60/40 if you need to carry long items like skis or lumber. You can still seat two people in back with the pass-through open.
This cargo space beats many SUVs while keeping your fuel costs lower. The smart design makes loading easier than taller vehicles that require lifting bags over a high lip.
Cargo Facts:
- 413-litre trunk capacity
- 60/40 split-folding rear seats
- Wide trunk opening
- Low loading height
- Spare tire doesn't take up cargo space
LX Base Trim
The LX gives you all the basics plus some extras. You get wireless phone connection, a backup camera, and safety features like collision warning and lane keeping help.
This base trim includes features that cost extra on many competitors. Air conditioning, heated front seats, and smart cruise control come standard, making the LX a solid value choice.
EX Mid-Level Trim
The EX adds 17-inch alloy wheels, blind spot monitoring, and a 6-speaker stereo. You also get heated side mirrors and wireless phone charging.
The EX targets buyers who want extra safety tech and comfort features without jumping to the highest price point. The blind spot system helps with lane changes, while the wireless charger keeps your phone powered without cables.
EX+ Enhanced Trim
The EX+ gets a power sunroof and synthetic leather seats. The windows also get an auto-up feature for both front seats.
This trim adds the comfort features that make longer drives more pleasant. The sunroof opens up the cabin feel, while the synthetic leather seats look better and clean easier than cloth.
GT-Line Turbo Performance Trim
This is where the fun starts. The GT-Line gets the turbo engine, sport suspension, and 18-inch wheels. Inside, you get dual 12.3-inch screens and GT-Line sport seats.
The GT-Line changes how the K4 drives with its multi-link rear suspension and larger brakes. The sport seats hold you in place during corners, while the paddle shifters let you control gear changes manually.
GT-Line Turbo Limited Top Trim
The Limited adds premium features like cooled front seats, a Harman Kardon sound system, and a 360-degree camera system. You also get Digital Key 2.0 to unlock the car with your phone.
This top trim gives you luxury features at a reasonable price. The 360-degree camera makes parking easier, while the premium audio system brings concert-quality sound to your daily drives.
