CarGurus Analysis: 2025 Kia K4

Picture of 2025 Kia K4 ## Summary - With 5,865 currently listed for sale on CarGurus and an **average price of $19,409.00**, 18.3% of 2025 Kia K4s for sale on CarGurus are rated as good or great deals. - **Favorably reviewed:** Owners rated the 2025 Kia K4 4 / 5 stars and CarGurus experts gave it an 7.8 / 10. - **94.4% of 2025 Kia K4 models on CarGurus are accident free**. - The 2025 Kia K4 replaces the Kia Forte, offering a redesigned exterior, improved technology features, and enhanced passenger and cargo space, making it an attractive choice in the compact sedan market. ## Why it stands out The 2025 Kia K4 stands out for its significant redesign from the outgoing Forte, showcasing a sleeker look and enhanced features that appeal to younger buyers or those seeking an economical second vehicle. This compact sedan boasts impressive cargo space of 14.6 cubic feet, a class-leading figure, along with spacious rear seating that rivals larger vehicles, offering 38 inches of legroom. Kia has equipped the K4 with a suite of modern technology features, including a standard 12.3-inch touchscreen, wireless charging, and advanced driver-assistance systems, appealing to tech-savvy consumers. However, the performance, particularly in non-Turbo trims, might feel underwhelming to some, as the base 2.0-liter engine produces 147 horsepower, which is notably less engaging than competitors like the Honda Civic. Nonetheless, the K4’s blend of practicality, stylish design, and affordability makes it a strong contender in the market. ## Other model years to consider - **[2026 Kia K4](https://www.cargurus.com/Cars/l-Used-2026-Kia-K4-c34057)** - Average price: $19,409.00 - Good/great deal percentage: 18.3% - Total listings: 5,864 This analysis is based on CarGurus' proprietary market data from February 10, 2026, CarGurus experts' opinions, and generative AI.

This car is nice and exceeded all of my expectations. The original plan was to buy a Hyundai Sonata, but it changed when I got to the dealership and drove it.
