2026 Kia K4 Trim Levels: One Engine Until the GT-Line Turbo

This table lists all 8 versions of the 2026 K4 with each one's engine, its MSRP at launch and how much more it cost than the trim below it.

MSRP at launch for the 2026 model year, excluding the $1,245 destination charge. IVT is Kia's Intelligent Variable Transmission.

Use these launch MSRPs to compare trims, then browse our new inventory to see what a K4 sells for today.

The 2026 K4 has 2 engines, and this table gives each one's power and its EPA ratings on each body:

The 2.0-liter sedan is rated higher than the 2.0-liter hatchback in city, highway and combined driving, and on both bodies the turbo's extra power costs fuel economy.

Both engines run on regular gasoline, and every 2026 K4 is front-wheel drive.

Route 8 runs past our door and south toward Cranberry Township and I-79. If you commute that way in a K4, the 2.0-liter's higher EPA ratings make it the engine to choose, unless you want the turbo's extra power.

Butler County sits on the rolling hills of the Allegheny Plateau, and Western Pennsylvania winters bring snow and road salt. If you want all-wheel drive for hills and snow, look past the front-wheel-drive K4 to the other Kias in our new inventory.

Every 2026 K4 seats 5 and has a 12.3-inch touchscreen that connects your phone through wired or wireless Apple CarPlay and Android Auto. Each one also has a smart key with push-button start, USB-C charging ports for the front and rear seats, and power-adjustable heated side mirrors.

Front airbags, side airbags for the front and rear seats, and full-length side curtain airbags come standard on every K4. The National Highway Traffic Safety Administration (NHTSA) rates both the 2026 K4 sedan and the 2026 K4 Hatchback 5 stars overall, with a 4-star frontal crash rating and 5-star side crash and rollover ratings.

Every 2026 K4 carries Kia's 10-year/100,000-mile limited powertrain warranty for the original owner and a 5-year/60,000-mile limited basic warranty, each ending at its time or mileage limit, whichever comes first. You can read what Kia's basic and powertrain warranties cover before you buy.

Each 2026 K4 sedan trim builds on the one below it. Our 2026 Kia K4 overview covers the sedan's specifications in more depth.

The K4 LX starts the sedan ladder with the touchscreen and standard driver-assistance features every K4 shares, plus 16-inch steel wheels with dark gray covers, cloth seats, manual air conditioning and 4 speakers. Choose the LX if keeping the price down matters most. If you often back out of busy parking spaces or carry long items with a passenger in the back, the LXS is the better fit.

The K4 LXS keeps the LX's cloth seats and manual air conditioning. Over the LX, it adds:

• Blind-Spot Collision Warning with Parallel Exit, which also alerts you when you pull out of a parallel parking space
• Rear Cross-Traffic Collision-Avoidance Assist, which warns of traffic crossing behind you as you back out and can help with braking
• Safe Exit Warning, so anyone getting out is warned of a vehicle coming from behind
• A 60/40 split-folding rear seat
• 16-inch dark gray alloy wheels in place of the steel wheels
• Drive Mode Select with Normal and Sport modes
• Two more speakers, for 6 in all

Stop at the LXS if those features cover your list. It has neither heated seats nor automatic climate control, so keep going to the EX if you want them.

The K4 EX is the comfort step on the sedan. Over the LXS, it adds:

• SynTex seats in place of cloth (SynTex is Kia's artificial leather)
• Heated front seats
• Dual-zone automatic climate control with a 5-inch climate display
• A wireless phone charger
• 17-inch black machine-finish alloy wheels and a gloss black grille with chrome trim
• A SynTex steering wheel and shift knob, soft-touch upper door trim and sliding sun visors with LED illumination

The EX keeps the 6-way manual driver's seat, and no K4 below the GT-Line offers a sunroof. Pick the EX if heated seats and automatic climate control are on your list but a sporty look is not.

The K4 GT-Line keeps the EX's 2.0-liter engine and EPA ratings but changes how the sedan looks and rides. Over the EX, it adds:

• GT-Line styling, including a gloss black GT-Line bumper and grille and satin chrome belt-line trim
• 18-inch black machine-finish alloy wheels
• A sport-tuned suspension that uses a multi-link design at the rear in place of the torsion-beam axle
• Steering-wheel paddle shifters
• A 10-way power driver's seat with power lumbar support
• A three-spoke, two-tone SynTex sport steering wheel and GT-Line SynTex door trim

It is also the first K4 sedan trim that takes factory packages, which can add a sunroof and ventilated seats. Choose the GT-Line for the sporty look and the power seat; for more horsepower, keep going to the GT-Line Turbo.

The K4 GT-Line Turbo is the only K4 sedan with the turbo engine, and it comes standard with several features the GT-Line offers only in packages. Over the GT-Line, it adds:

• The 1.6-liter turbo with an 8-speed automatic, replacing the 2.0-liter and IVT
• LED projector headlights instead of the reflector type, plus LED fog lights and full LED taillights
• A power wide sunroof, an acoustic windshield and rear climate vents
• Navigation, a 12.3-inch digital instrument display that replaces the 4-inch screen in the gauge cluster, and Harman Kardon 8-speaker audio with a subwoofer
• Kia AI Voice Assistant
• Highway Driving Assist and Navigation-based Smart Cruise Control-Curve

It has the lowest EPA ratings of any K4 sedan. Buy the GT-Line Turbo if you want the turbo along with the most standard equipment in the K4 sedan lineup.

The 2026 K4 Hatchback comes in 3 trims, the EX, GT-Line and GT-Line Turbo, so there is no hatchback LX or LXS. Each hatchback trim launched $500 above the sedan trim with the same name.

The reason to choose the hatchback is cargo room. With the rear seat up, its cargo area holds 22.2 cubic feet, compared with 14.6 cubic feet in the sedan's trunk. The rear seat splits 60/40 and folds on every hatchback.

Like the sedan EX, the hatchback EX has heated SynTex seats, dual-zone automatic climate control and a wireless phone charger. The hatchback GT-Line and GT-Line Turbo bring the same styling, suspension and turbo upgrades as their sedan versions, and they are the only K4s offered in Sparkling Yellow paint. For a closer look, read our 2026 Kia K4 Hatchback overview.

Only the top 2 trims on each body, the GT-Line and the GT-Line Turbo, take factory packages. This table gives each package's price at launch, the trims it fits and what it adds.

On either body, a GT-Line with the sunroof and the Premium Package launched $800 below the GT-Line Turbo. That GT-Line has ventilated front seats, driver's seat memory and a heated steering wheel, which the GT-Line Turbo gets only by adding its Technology Package. The extra money for the GT-Line Turbo buys the turbo engine, LED projector headlights with fog lights and rear climate vents.

Choose a GT-Line with packages if comfort matters more to you than power. Choose the GT-Line Turbo for the engine, and add the Technology Package if you also want the ventilated seats and the extra camera views.

Every 2026 K4, sedan or hatchback, comes standard with these driver-assistance features:

• Forward Collision-Avoidance Assist with pedestrian, cyclist and junction-turning detection
• Smart Cruise Control with Stop & Go
• Lane Keeping Assist and Lane Following Assist
• High Beam Assist and Driver Attention Warning
• Rear Occupant Alert and a Rear View Monitor with parking guidelines

Lane Following Assist helps keep the car centered in its lane, but it does not drive the car for you, so keep your hands on the wheel and your eyes on the road. Blind-Spot Collision Warning, Rear Cross-Traffic Collision-Avoidance Assist and Safe Exit Warning join the sedan at the LXS and come on every hatchback.

The Technology Package, offered only on the GT-Line Turbo, adds these driver-assistance features:

• Surround View Monitor and Blind-Spot View Monitor
• Parking Distance Warning for the front, rear and sides
• Reverse Parking Collision-Avoidance Assist
• Blind-Spot Collision-Avoidance Assist, a separate system from the Blind-Spot Collision Warning that comes standard on every K4 from the LXS up
• Forward Collision-Avoidance Assist 2 and Highway Driving Assist 2

Digital Key 2, also part of that package, works with an eligible Kia Connect subscription and a compatible smart device with an active data plan.

Four questions settle which 2026 K4 trim fits you:

• Sedan or hatchback: The hatchback has more cargo room but starts at the EX, so the lower-priced LX and LXS are sedans only.
• The 2.0-liter or the turbo: Only the GT-Line Turbo gets the 1.6-liter turbo, which adds power but has lower EPA ratings on both bodies.
• Which everyday features you need: Blind-spot warnings start at the LXS sedan, heated seats at the EX and a power driver's seat at the GT-Line. Every hatchback has the warnings and heated seats.
• A GT-Line with packages or the GT-Line Turbo: With the sunroof and Premium Package, a GT-Line cost less at launch than a GT-Line Turbo but keeps the 2.0-liter engine.

Choose the first 2026 K4 trim that covers everything on your list:

• Spending as little as possible: The LX sedan.
• Heated seats and automatic climate control: An EX, sedan or hatchback.
• More cargo room: The K4 Hatchback, which starts at the EX.
• The best K4 fuel economy: Any 2.0-liter sedan, LX through GT-Line.
• A sporty look and a power driver's seat: A GT-Line, sedan or hatchback.
• Turbo power: The GT-Line Turbo, on either body.
• Surround View Monitor or Digital Key 2: A GT-Line Turbo with the Technology Package.

Driving a 2.0-liter K4 and a GT-Line Turbo back to back is the clearest way to decide whether the turbo is worth it, so set up a K4 test drive and tell us which versions you want to try.

Before you visit, look over the K4 sedan's styling and features and the K4 Hatchback's design and cargo space.
