If you’re in the market for a new sedan, the compact 2025 Kia K4 and the midsize 2025 Kia K5 have probably caught your eye. Both sedans are stylish, tech-forward, and available in several trim levels with a choice of powertrains and premium features. Before you stop by your Mooresville Kia dealership to see them for yourself, take a look at what separates these sedans and what they have in common.
K4 vs. K5: A Sedan for Every Lifestyle at Your Kia Dealership
Put the K4 and K5 side by side, and you’ll notice that they both have sweeping silhouettes and striking LED headlights and taillights. The K4’s compact frame comes in at 185.4 inches in length, while the K5 is 193.1 inches long, so the K4 may be more suitable for drivers who frequently navigate small streets or parallel park.
Inside, the K5 provides 105.3 cubic feet of passenger space, while the compact K4 has up to 98.7 cubic feet. Despite its smaller size, the K4 has a class-leading 38 inches of rear legroom and 37.3 inches of rear headroom, so rear-seat passengers can ride comfortably. Both vehicles come with standard cloth seat trim and offer SynTex synthetic leather as an option, but the K5 comes standard with features that are optional on the K4, like dual-zone auto climate control.
Power and Capability
Both the K4 and K5 offer two efficient powertrain options that are backed by Kia’s industry-leading 10-year/100,000-mile warranty program. The K4’s standard powertrain is a 147-horsepower 2.0-liter 4-cylinder engine with an Intelligent Variable Transmission that averages up to an EPA-estimated 34 MPG combined. When you choose its GT-Line Turbo trim, you’ll get a 190-horsepower 1.6-liter 4-cylinder turbo engine with an 8-speed automatic transmission and 29 MPG combined efficiency.
Most K5 trim levels are powered by a 191-horsepower 2.5-liter 4-cylinder engine, paired to an 8-speed automatic transmission for efficiency of up to 30 MPG combined. The high-performance GT accelerates from 0 to 60 mph in just 5.4 seconds, thanks to its turbocharged 2.5-liter 4-cylinder engine that creates 290 horsepower and averages 27 MPG combined. The K5 also offers all-wheel drive on its GT-Line trim for added confidence in all kinds of weather.
Advanced Tech Features
Convenience and safety tech features come standard on both the K4 and K5, including a 12.3-inch touchscreen infotainment display and Forward Collision-Avoidance Assist, which can help you avoid a collision with warnings and automatic braking. Both models also include a Smart Trunk, which opens hands-free, and wireless Apple CarPlay and Android Auto, which pairs your smartphone to the infotainment display.
