2025 Kia K4 vs 2025 Kia K5

Serving Highland Park, IL

The 2025 Kia K4 makes its debut as the stylish new replacement for the outgoing Forte, while the 2025 Kia K5 continues to build on the legacy of the former Optima. Although these two sedans sit close together in Kia's lineup, they cater to different needs when it comes to size, power, and features. If you're shopping for a new sedan in Highland Park, IL, and unsure which model suits you best, the experts at McGrath Kia of Highland Park are here to help you compare.

Performance

The all-new 2025 Kia K4 delivers two engine options that mirror the outgoing Forte lineup. The standard 2.0L 4-cylinder engine generates 147 horsepower and is paired with a CVT, ideal for efficient daily commuting in and around Highland Park. For drivers wanting more punch, the available 1.6L turbocharged engine delivers 190 horsepower and comes with an 8-speed automatic transmission for smoother, sportier shifts.

In comparison, the 2025 Kia K5 is a midsize sedan with bolder engine options. The base 2.5L 4-cylinder engine puts out 191 horsepower and is available with front-wheel or all-wheel drive—perfect for those who face Chicago-area winters. If performance is a top priority, the K5's available turbocharged 2.5L engine cranks out an exhilarating 290 horsepower, offering a true sports-sedan experience.

Appearance

Visually, the 2025 Kia K4 and K5 both turn heads, but in different ways. The K4 has a futuristic, coupe-like silhouette with a long hood, geometric pinwheel-style wheels, and sweeping curves. At the front, the grille integrates seamlessly with a unique zigzag LED light signature, giving it a standout presence in city traffic or suburban parking lots.

The 2025 Kia K5, on the other hand, has a more aggressive stance with sharper lines, angular body creases, and a bolder rear design. Its shorter grille connects with amber LED light ribbons, while the bumper and lower fascia are sculpted for a more athletic, assertive profile. For Highland Park drivers who want something sporty and sophisticated, the K5's styling may hit the mark.

Features

Inside, both sedans bring modern comfort and technology to the forefront. The 2025 Kia K4 features wireless Apple CarPlay® and Android Auto™, a 12.3-inch infotainment screen paired with a matching digital instrument cluster, a 5-inch climate display, adaptive cruise control, highway driving assist, and speed limit assist—great for navigating both city and expressway routes.

The 2025 Kia K5 builds on this foundation by adding upscale touches. In addition to the standard features, the K5 includes a Bose® premium audio system, wireless charging pad, front and rear parking sensors, a heated steering wheel, toggle-style driver display controls, and additional USB-C ports. These upgrades make the K5 a strong contender for drivers looking for extra comfort and convenience on longer drives through Lake County and beyond.
