Compare the2025 Kia K4VS 2025 Acura Integra

The K4 GT-Line Turbo offers an optional Surround View Monitor to allow the driver to see objects all around the vehicle on a screen. The Integra only offers a rear monitor and front and rear parking sensors that beep or flash a light. That doesn’t help with obstacles to the sides.

Both the K4 and Integra have rear cross-traffic warning, but the K4 LXS/EX/GT-Line has Rear Cross-Traffic Collision-Avoidance Assist (automatically applies the brakes) to better prevent a collision when backing near traffic. The Integra’s Rear Cross Traffic Monitor doesn’t automatically brake.

Both the K4 and the Integra have standard driver and passenger frontal airbags, front and rear side-impact airbags, side-impact head airbags, front and rear seatbelt pretensioners, front wheel drive, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, rearview cameras, driver alert monitors and available blind spot warning systems.

The K4 comes with a full 5-year/60,000-mile basic warranty, which covers the entire car and includes 24-hour roadside assistance. The Integra’s 4-year/50,000-mile basic warranty expires 1 year or 10,000 miles sooner.

Kia’s powertrain warranty covers the K4 4 years and 30,000 miles longer than Acura covers the Integra. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 10 years or 100,000 miles. Coverage on the Integra ends after only 6 years or 70,000 miles.

There are almost 3 times as many Kia dealers as there are Acura dealers, which makes it much easier should you ever need service under the K4’s warranty.

The Integra doesn’t offer a hands-free gesture to open its liftgate, forcing you to put cargo down if your hands are full.

The power windows standard on both the K4 and the Integra have locks to prevent small children from operating them. When the lock on the K4 is engaged the driver can still operate all of the windows, for instance to close one opened by a child. The Integra prevents the driver from operating the other windows just as it does the other passengers.
