Kia K5: Price, Specs, Features & Review

Base MSRP:~ $27,490

The Kia K5 is a midsize sedan for buyers who want more space, power, and road presence than a compact car without moving into SUV pricing. It replaced the Kia Optima nameplate in the U.S. and now serves as Kia’s main gasoline sedan above the compact Kia K4. IIHS notes that the K5 was introduced for the 2021 model year as the Optima replacement.

The current K5 is aimed at commuters, small families, style-focused sedan buyers, and drivers who still prefer a low-slung car over a crossover. It offers a standard 2.5L engine, available all-wheel drive on the GT-Line AWD, a stronger 290-hp GT model, generous passenger space, a large trunk, and a long list of standard driver-assistance features.

Expert Tip

For most buyers, the Kia K5 GT-Line is the best trim to consider first. It gives the K5 the sportier look people usually want from this sedan, adds more desirable equipment than the LXS, and keeps pricing lower than the EX and GT.

About the Kia K5

The Kia K5 is Kia’s midsize sedan and the successor to the Kia Optima. It competes in a shrinking but still important sedan class against the Toyota Camry, Honda Accord, Hyundai Sonata, Nissan Altima, and Subaru Legacy.

Its main appeal is style and value. The K5 has a lower, wider look than many family sedans, and Kia uses sharp lighting, a fastback-like roofline, and aggressive trim designs to make it feel more emotional than a typical commuter car.

The K5 also gives buyers a practical reason to choose a sedan over a compact SUV. It has a roomy cabin, large trunk, good highway comfort, and better handling balance than many taller crossovers. For drivers who do not need SUV cargo height, the K5 can feel more stable, more efficient, and more enjoyable on long drives.

Price & Trims

The 2026 Kia K5 lineup starts at $27,490 for the LXS and reaches $33,590 for the GT before options. Kia lists a $1,245 destination charge, and pricing can change by dealer, location, taxes, fees, and available packages.

TrimStarting MSRPEngine / TransmissionDrivetrainKey Features

EX$34,9902.5L GDI / 8-speed automaticFWDComfort-focused trim, premium features, higher convenience level

The LXS is the entry trim. It makes sense for buyers who want the K5’s size, design, and standard safety features at the lowest price.

The GT-Line is the best visual value. It adds sportier design cues and a stronger feature set without jumping to the GT’s higher running costs.

The GT-Line AWD is the best pick for buyers who drive in snow, rain, or rough weather. Kia’s feature sheet lists AWD as optional on GT-Line and not available on LXS, EX, or GT.

The EX is the comfort trim. It is priced high compared with the GT-Line, but it makes sense for buyers who care more about convenience and cabin features than sporty looks.

The GT is the performance trim. It is the strongest K5 and the most entertaining version, but it is front-wheel drive only.

Engine, Performance & Fuel Economy

2.5L 4-Cylinder Engine

Most Kia K5 trims use a 2.5L 4-cylinder GDI engine. Kia rates this engine at 191 hp and 181.5 lb-ft of torque. It comes with an 8-speed automatic transmission.

ItemK5 2.5L
Engine2.5L inline-4 GDI
Horsepower191 hp
Torque181.5 lb-ft
Transmission8-speed automatic
DrivetrainFWD or available AWD depending on trim
Fuel TypeRegular unleaded gasoline
Best UseCommuting, highway driving, family use

This engine is the sensible choice. It has enough power for normal city and highway driving, and it feels better suited to a midsize sedan than the smaller engines used in older economy-focused sedans.

The 2.5L engine is not quick in a sporty sense, but it is smooth enough for daily use. It works best for buyers who want predictable power, simple ownership, and lower fuel costs than the GT.

2.5L Turbocharged GT Engine

The K5 GT uses a 2.5L turbocharged 4-cylinder engine with gasoline direct injection and multi-port injection. Kia rates it at 290 hp and 311 lb-ft of torque, paired with an 8-speed wet dual-clutch transmission.

ItemK5 GT
Engine2.5L turbocharged inline-4
Horsepower290 hp
Torque311 lb-ft
Transmission8-speed wet DCT
DrivetrainFront-wheel drive
Fuel TypeRegular unleaded gasoline
Best UseStrong acceleration, sporty daily driving, highway passing

The GT changes the K5’s personality. It gives the sedan serious straight-line performance and makes it feel much more energetic than the standard car.

The tradeoff is traction and fuel economy. With 311 lb-ft going to the front wheels, the GT can feel eager under hard acceleration. It is quick, but buyers should not confuse it with an all-wheel-drive sport sedan.

Driving Experience

The Kia K5 feels stable, comfortable, and easy to drive. Its midsize footprint gives it better highway confidence than smaller sedans, and the low seating position helps it feel more planted than many compact SUVs.

The standard 2.5L engine gives the K5 enough power for normal driving. It is not dramatic, but it handles daily commuting, school runs, highway cruising, and city traffic without feeling underpowered.

The 8-speed automatic transmission is a strong fit for the base engine. It feels more natural than a CVT and helps the K5 feel more like a traditional midsize sedan.

Ride comfort is one of the K5’s better qualities. It absorbs normal road bumps well and feels calm on longer drives. The GT-Line adds style, but it does not turn the car into a harsh sport sedan.

The GT is the most exciting version. The 290-hp turbo engine delivers strong passing power and quick acceleration. Kia also lists sport-tuned suspension parts and paddle shifters for the GT, giving it a sharper feel than the rest of the lineup.

The GT-Line AWD is the better real-world choice for bad weather. It will not feel as quick as the GT, but available AWD gives buyers more confidence in rain, snow, and colder climates.

Fuel Economy

EPA fuel economy depends on engine, drivetrain, and stop-start setup. The most efficient 2026 K5 version listed by FuelEconomy.gov is the 2.5L model with stop-start, rated at 26 mpg city, 37 mpg highway, and 30 mpg combined.

VersionCity MPGHighway MPGCombined MPG
K5 2.5L with stop-start263730
K5 2.5L automatic253629
K5 AWD 2.5L automatic243327
K5 2.5L turbo DCT233327

The 2.5L front-wheel-drive models are the best choice for fuel economy. They are efficient enough for commuting and long highway trips without needing a hybrid system.

The AWD and turbo versions use more fuel. That is expected because AWD adds weight and drivetrain loss, while the turbo engine prioritizes power. Buyers focused on fuel savings should stay with a front-wheel-drive 2.5L trim.

0–60 MPH Acceleration

Tested under real-world driving conditions.

Version TestedEstimated 0–60 MPHNotes
K5 2.5L FWDAround 7.7–8.2 secondsSmooth and adequate for daily driving
K5 GT-Line AWDAround 7.0–7.5 secondsBetter traction and stronger response
K5 GT 2.5TAround 5.4–5.8 secondsQuick for a mainstream midsize sedan

The standard K5 is not slow, but it is not the performance version. It feels best when driven smoothly.

The GT is the model to buy if acceleration matters. Its 290-hp turbo engine gives the K5 one of the strongest power figures in the mainstream midsize sedan class.

Interior, Comfort & Technology

The Kia K5 has a roomy midsize-sedan cabin with strong front-seat space and a usable rear seat. Kia lists 46.1 inches of front legroom, 35.2 inches of rear legroom, 105.3 cubic feet of passenger capacity, and 15.6 cubic feet of cargo area capacity.

Interior MeasurementKia K5
Front Headroom40.2 in. without panoramic sunroof

Rear Legroom35.2 in.
Front Shoulder Room58.0 in.
Rear Shoulder Room56.1 in.
Passenger Capacity105.3 cu. ft.
Cargo Capacity15.6 cu. ft.

The front seats are spacious, and the driving position suits longer commutes. Rear legroom is not as generous as the front, but the K5 can still handle adults in the back seat for normal trips.

Cargo space is strong for a sedan. The 15.6-cubic-foot trunk can handle luggage, groceries, work gear, and everyday family items.

Technology is one of the K5’s key strengths. Available features include a 12.3-inch TFT cluster, Digital Key 2.0 Advanced, Bose 12-speaker audio, ventilated front seats, heated steering wheel, surround-view monitor, blind-view monitor, and power-folding mirrors through higher trims and packages.

The GT-Line is the best cabin value for many shoppers. The EX is better for comfort-focused buyers, while the GT is better for drivers who want performance first.

Safety Features & Ratings

The Kia K5 includes a strong list of standard and available safety features. Kia lists blind-spot collision avoidance, rear cross-traffic collision avoidance, parking distance warning, forward collision avoidance with cyclist and junction-turning detection, smart cruise control with stop and go, lane keeping assist, lane following assist, driver attention warning, rear occupant alert, high beam assist, and safe exit assist.

The updated side test applies to 2021–2026 models and was rated Marginal overall.

Should You Buy the Kia K5?

You should buy the Kia K5 if you want a stylish midsize sedan with good space, strong features, available AWD, and more personality than a basic commuter car. It is a strong fit for buyers who want sedan comfort without SUV pricing.

The best trim for most buyers is the GT-Line. It gives the K5 the right look, enough features, and a reasonable price. Choose the GT-Line AWD if you live in an area with snow or heavy rain.

The EX is the better choice if you want a more comfort-focused sedan. It is not the sporty pick, but it fits buyers who want more convenience and cabin features.

The GT is worth buying if you want performance. It is quick, powerful, and more exciting than the standard K5. Skip it if you want AWD, maximum fuel economy, or the lowest ownership cost.

You should also compare the K5 against the Toyota Camry, Honda Accord, Hyundai Sonata, Nissan Altima, and Subaru Legacy. The K5 wins on style and value, but rivals may offer stronger hybrid choices, resale value, or AWD coverage.
