The 2027 Kia K4 trim range in Hamburg runs from the $22,390 LX to the $28,490 GT-Line Turbo, with LXS, EX and GT-Line between them. Reading and Allentown shoppers get the same sedan dimensions throughout; the real changes are equipment, suspension and, at the top, the engine.

K4 Trim Lineup at a Glance

The first four trims share a 147-hp 2.0L engine; GT-Line Turbo moves to a 190-hp turbocharged 1.6L engine.

Starting MSRP excludes the $1,245 destination and handling charge, taxes, title, license, options and dealer charges. Actual dealer price may vary.

Trim-by-Trim Breakdown

Every K4 sedan is front-wheel drive, seats five and carries a 12.3-inch touchscreen with wireless smartphone integration.

LX — $22,390

LX brings the core K4 equipment together at the lowest starting MSRP. Its 147-hp engine uses an Intelligent Variable Transmission, and the 16-inch wheels wear steel covers. Smart Key, Smart Cruise Control with Stop & Go and wireless Apple CarPlay and Android Auto are standard. Cloth seating and a simple climate-control layout suit a buyer who wants useful technology without moving into the higher equipment groups.

LX is the price-conscious choice for regular travel between Reading and the store. Its cabin dimensions match those of the higher trims, so the entry point still includes 38.0 inches of rear legroom.

LXS — $23,590

LXS keeps the same engine and transmission, then adds 16-inch alloy wheels, a 60/40 split-folding rear seat, Blind-Spot Collision Warning with Parallel Exit and Rear Cross-Traffic Collision-Avoidance Assist. The $1,200 step from LX buys cargo flexibility and additional awareness features rather than a different engine.

A shopper carrying sports bags for Coca-Cola Park visits or a longer item from a weekend errand gets a more adaptable rear seat. LXS keeps cloth upholstery and an accessible starting price.

EX — $24,590

EX pairs the 2.0L powertrain with 17-inch alloy wheels, heated front seats and SynTex upholstery. Dual-zone automatic climate control and a wireless phone charger are standard. These are useful daily upgrades for repeated Route 61 trips and cold starts before the cabin reaches its selected temperature.

At $1,000 above LXS, EX bundles seat comfort, cabin temperature control and charging convenience. It is a strong everyday choice for an Allentown commuter who wants these features together rather than sport styling.

GT-Line — $25,590

GT-Line keeps the 147-hp 2.0L engine and adds sport-tuned suspension with an independent multi-link rear layout, 18-inch wheels and GT-Line exterior and interior styling. A power-adjustable driver’s seat and sport steering wheel distinguish the driving position. Heated SynTex front seats and dual-zone climate control remain standard.

The available Sunroof Package adds a wide sunroof; applicable additional packages offer comfort and technology upgrades. GT-Line suits a driver who enjoys a sportier chassis and design while retaining the 2.0L engine’s EPA fuel-economy figures.

GT-Line Turbo — $28,490

GT-Line Turbo delivers 190 hp and 195 lb-ft through an eight-speed automatic transmission. Its standard equipment includes a wide sunroof, Harman Kardon premium audio, navigation, a 12.3-inch instrument display and black-finish 18-inch wheels. The sport-tuned multi-link rear suspension supports its performance-oriented character.

The Technology Package offers further driver assistance and comfort equipment, including available ventilated front seats. For a Lebanon or Quakertown shopper who wants stronger acceleration and a richer standard cabin, this trim combines the larger power output with the top equipment group.
