The 2025 Kia K4 is a new compact/entry‑level sedan from Kia, introduced as a replacement for the Kia Forte in the U.S. market. It’s designed to bring more style, more tech, and a more premium feel to the compact sedan segment.
The K4 marks the fourth generation of Kia’s compact sedan line in the U.S., taking over from the Forte.
Kia positioned the K4 to deliver “segment‑above” technology and comfort while still competing in the compact sedan category.
It debuted for the 2025 model year with availability beginning around September 2024 for base trims, with higher‑spec and turbo versions arriving later.
Standard engine: 2.0‑liter naturally aspirated 4‑cylinder making about 147 hp and 132 lb‑ft torque, paired with an Intelligent Variable Transmission (IVT).
Optional / higher trim (GT‑Line Turbo): a 1.6‑liter turbocharged 4‑cylinder producing ~ 190 hp and 195 lb‑ft torque, with an 8‑speed automatic transmission.
Suspension: base trims use standard front struts; higher trims (GT‑Line and Turbo) come with a multi‑link rear suspension. Kia also worked on reducing noise‑vibration‑harshness (NVH) in higher trims, with features like acoustic windshield and acoustic tires (on 18‑inch wheel models).
Styling is more modern and sporty, with a fastback‑like roofline, sleek profile, and updated exterior details especially on GT‑Line variants.
Interior features include a digital cockpit with a large combined display (nearly 30 inches split among instrument display, climate display, and touchscreen).
Standard connectivity includes wireless Apple CarPlay / Android Auto. Over‑the‑air (OTA) update capabilities are available. Digital Key 2.0 with Ultra‑Wideband is an available feature.
Here are the trim levels for the K4 in the U.S. and what distinguishes them:
| Trim | Key Features / Differences |
|---|---|
| LX | Base model, standard 2.0L engine, basic technology and driver aids, smaller wheels. |
| LXS | Adds a few more comfort / style / cosmetic options over LX. |
| EX | More upgraded interior materials, possibly more standard features. |
| GT‑Line | Sportier styling, larger wheels, more appearance enhancements, better suspension (multi‑link) in some trims. |
| GT‑Line Turbo | High‑performance trim with the 1.6L turbo engine, more power & torque, upgraded transmission, likely more premium interior / feature options. |
The K4 has 11 standard ADAS (advanced driver assistance systems) features across trims, with up to ~29 available depending on variant.
Standard safety features include things like Lane Keeping Assist (LKA), Intelligent Speed Limit Assist (ISLA), Smart Cruise Control with Stop & Go, Forward Collision Avoidance (FCA‑1.5) etc.
Additional technologies on higher trims: Forward Collision Avoidance 2 (FCA‑2) with extra detection capabilities, Evasive Steering Assist, 360° Surround View Monitor.
Airbags: includes standard rear side airbags (making for 8 in total in many trims).
Ratings: The 2025 Kia K4 earned IIHS Top Safety Pick+ (TSP+) for models built after Jan 2025.
Base 2.0L engine trims have EPA estimates around 30 mpg city / 40 mpg highway / ~34 mpg combined on some trims.
Turbo 1.6L trim has lower efficiency: approximately 26 city / 36 highway / 29 combined mpg.
The IVT (variable auto transmission) in the non‑turbo trims aids in improving efficiency under lighter loads.
The K4 replaces the Forte, and is more premium in terms of features, styling, and cabin room.
In its class it competes with compact‑sedans like the Toyota Corolla, Hyundai Elantra, Volkswagen Jetta, etc.
Compared to predecessor (Forte), it’s more expensive but offers more content, more advanced driver assistance features, more premium styling.
U.S. MSRP starts at about $21,990 for the base LX trim, excluding destination fee.
Higher trims cost more: EX, GT‑Line, and the GT‑Line Turbo (which can run ~$28,000+).
Including destination, some sources list starting around $23,145 for base model.

Also earned IIHS Top Safety Pick for those built before Nov 2024.
Recognized for having segment‑leading rear legroom and strong safety and tech package.
