What’s the Difference Between 2026 K5 Trims?

LXS ($28,735)

The entry trim covers more than the basics. Standard features include a 12.3-inch touchscreen with wireless Apple CarPlay and Android Auto, dual-zone automatic climate control, front and rear LED lighting, keyless entry and start, and Kia’s full Drive Wise active-safety suite. The 2.5L naturally aspirated four-cylinder produces 191 horsepower and returns up to 26 mpg city and 37 mpg highway. For St. Louis commuters and families who want a polished sedan without overextending a budget, the LXS is a strong starting point.

GT-Line (~$29,565 FWD / ~$31,165 AWD)

The GT-Line adds 18-inch gloss-black wheels, a wireless phone charger, and styling enhancements that give the K5 a sportier presence. It is the only trim in the lineup available with all-wheel drive, which adds approximately $1,600 and brings Drive Mode Select with Snow Mode — a practical consideration for South County winter commutes. Both GT-Line configurations keep the 191-horsepower engine.

GT (~$34,835)

The K5’s performance trim is the lineup’s most distinctive choice, and it costs less than the EX. The GT swaps in a turbocharged 2.5L four-cylinder producing 290 horsepower and 311 lb-ft of torque, paired with an 8-speed wet dual-clutch transmission. The result is 0-60 in approximately 5.4 seconds — territory that overlaps with sports sedans costing significantly more. Exterior upgrades include quad-tip exhaust, 19-inch gloss-black wheels, and Neon Green brake calipers. For a closer look at everything the GT brings, the 2026 Kia K5 performance overview covers the full picture.

EX ($36,235)

The top trim shifts focus entirely from performance to premium comfort. The EX is the only trim with ventilated front seats, a 12-speaker Bose audio system, a 12.3-inch curved digital instrument cluster, a 360-degree surround-view camera, and Digital Key 2.0. It is not the most powerful K5 — that is the GT — but it is the most refined. For buyers who want a luxury sedan experience without a luxury-sedan price, the EX delivers it.

Long-Term Value at Suntrup Kia South

Every 2026 Kia K5 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 — whether you’re driving the LXS’s naturally aspirated engine or the GT’s turbocharged setup. That coverage is standard on every trim and is among the longest powertrain warranties offered on any sedan in this segment.

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. On a K5 purchase, that calculation can meaningfully reduce what you owe on the transaction.
