Kia K5 trim comparison
2025 Kia K5 GT-Line vs GT
The K5 GT-Line starts at $28,190 while the GT is $33,290. That $5,100 gap buys 6 meaningful differences.
This trim jump changes the engine from 2.5L I4 to 2.5L I4 Turbo. Everything else is secondary to whether that powertrain difference matters for how you drive.
If you would notice the 2.5L I4 Turbo every week, the GT makes sense. If not, the GT-Line is the cleaner stop because this jump matters for the powertrain first and the trim badge second.
Think about this as a monthly tradeoff, not just a sticker gap. The GT adds about $90/month on a typical 60-month loan, or around $5,400 more overall with interest. If that different powertrain is not part of your real use case, the cheaper trim keeps more money in your pocket without changing the core experience you need.
Lock one trim, change the other side, and move through exact pair pages without resetting back to the full lineup every time.
