Based on the current pricing of the Kia Forte, which starts at around $17,890 for the base model, we can speculate that the 2025 Kia K4 could start at around $19,000-$20,000 for the base model. This would account for inflation and any potential advancements or upgrades in technology and features that may be included in the K4. Of course, this is just an estimate and actual pricing could vary depending on market conditions and other factors.
