What’s the Difference Between 2026 K4 Trims?

LX ($22,290 before destination): The K4’s entry price is genuinely hard to match in the compact sedan segment. The LX comes standard with a 12.3-inch touchscreen, wireless Apple CarPlay and Android Auto, four USB-C ports, LED headlights, and Kia’s full Drive Wise active-safety suite. The standard 2.0L four-cylinder produces 147 horsepower through a CVT and returns up to 39 mpg on the highway. For St. Louis commuters and first-time buyers who want well-equipped, efficient transportation well under $25,000, the LX is a serious value.

LXS and EX: These mid-range trims add comfort and convenience features — including split-folding rear seats on the LXS and upgraded interior materials, a wireless charging pad, and dual-zone climate control on the EX. The K4 is notable for class-leading second-row legroom in its segment, and it is particularly evident at EX and above where the interior is more fully appointed. Contact Suntrup Kia South for current LXS and EX pricing.

GT-Line: The GT-Line brings sport-styled exterior accents, 17-inch alloy wheels, heated front seats, and a more driver-focused cabin presentation while keeping the standard 2.0L engine. It sits just below the GT-Line Turbo in price and appeal. Contact the dealership for current GT-Line MSRP.

GT-Line Turbo ($28,390 before destination): The top trim swaps in a turbocharged 1.6L four-cylinder producing 190 horsepower, paired with an 8-speed automatic for quicker, more responsive acceleration. It adds a sunroof, digital instrument cluster, and projector LED headlights as standard. At under $30,000 with destination, it delivers performance-sedan output at a compact-sedan price.

The new K4 Hatchback: For 2026, Kia adds a five-door hatchback version starting at the EX trim ($24,990 before destination). The hatchback delivers up to 59.3 cubic feet of cargo space with the rear seats folded and carries the same class-leading rear legroom as the sedan — competitive with small crossovers in practicality while keeping the K4’s compact-car efficiency. EX, GT-Line, and GT-Line Turbo trims are available.

Safety, Warranty, and Long-Term Value at Suntrup Kia South

The 2026 Kia K4 earned 2026 IIHS TOP SAFETY PICK+ recognition for vehicles built after January 2025 — the institute’s highest safety designation. It also carries a 5-star overall NHTSA rating. Both apply to the sedan lineup and make the K4 one of the best-protected choices in its class.

Every 2026 K4 at Suntrup Kia South, located at 6263 S. Lindbergh Blvd. in St. Louis, is backed by Kia’s 10-year/100,000-mile limited warranty covering the powertrain. On a sub-$30,000 vehicle, that warranty is a meaningful long-term advantage over most competitors in this class.

Missouri’s trade-in tax benefit applies here too: sales tax is calculated on the difference between the new vehicle price and your trade-in value, not the full purchase amount. Knowing your trade-in value before you visit clarifies what the transaction actually costs.
