Compare the2023 Toyota CorollaVS 2023 Kia K5

The Corolla has standard Whiplash Injury Lessening Seats, which use a specially designed seat to protect the driver and front passenger from whiplash. During a rear-end collision, the Whiplash Injury Lessening Seats system allows the backrest to travel backwards to cushion the occupants and the headrests move forward to prevent neck and spine injuries. The K5 doesn’t offer a whiplash protection system.

The Corolla has a standard Secondary Collision Brake, which automatically applies the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The K5 doesn’t offer a post collision braking system: in the event of a collision that triggers the airbags, more collisions are possible without the protection of airbags that may have already deployed.

Both the Corolla and the K5 have standard driver and passenger frontal airbags, front and rear side-impact airbags, driver knee airbags, side-impact head airbags, front seatbelt pretensioners, front wheel drive, height adjustable front shoulder belts, plastic fuel tanks, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems, rearview cameras, driver alert monitors, available blind spot warning systems and rear cross-path warning.

The National Highway Traffic Safety Administration does 35 MPH front crash tests on new vehicles. In this test, results indicate that the Toyota Corolla is safer than the Kia K5:

New test not comparable to pre-2011 test results. More stars = Better. Lower test results = Better.

The National Highway Traffic Safety Administration does side impact tests on new vehicles. In this test, which crashes the vehicle into a flat barrier at 38.5 MPH and into a post at 20 MPH, results indicate that the Toyota Corolla is safer than the Kia K5:

New test not comparable to pre-2011 test results. More stars = Better. Lower test results = Better.

For its performance in IIHS driver-side and passenger-side small overlap frontal, moderate overlap frontal, updated side impact, headlight, and daytime pedestrian crash prevention testing, the Insurance Institute for Highway Safety grants the Corolla the rating of “Top Safety Pick” for 2023, a rating granted to only 53 vehicles tested by the IIHS. The K5 has not been fully tested, yet.

The Corolla’s 5 year corrosion warranty has no mileage limitations, but the corrosion warranty on the K5 runs out after 100,000 miles.

Toyota pays for scheduled maintenance on the Corolla for 2 years and 25000 miles. Toyota will pay for oil changes, lubrication and any other required maintenance. Kia doesn’t pay scheduled maintenance for the K5.

There are over 59 percent more Toyota dealers than there are Kia dealers, which makes it much easier should you ever need service under the Corolla’s warranty.

A reliable vehicle saves its owner time, money and trouble. Nobody wants to be stranded or have to be without a vehicle while it’s being repaired. Consumer Reports rates the Corolla’s reliability 16 points higher than the K5.

From surveys of all its subscribers, Consumer Reports’ January 2023 Auto Issue reports that Toyota vehicles are more reliable than Kia vehicles. Consumer Reports ranks Toyota first in overall reliability. Kia is ranked 9th.

On the EPA test cycle the Corolla gets better mileage than the K5:

The U.S. Environmental Protection Agency (EPA) certifies the Toyota Corolla as a “Super Ultra Low Emissions Vehicle” (SULEV). The Kia K5 is only certified to “Ultra Low Emissions Vehicle” (ULEV) standards.

The Corolla has a standard continuously variable transmission (CVT). With no “steps” between gears, it can keep the engine at the most efficient speed for fuel economy, or keep it at its peak horsepower indefinitely for maximum acceleration. The K5 doesn’t offer a CVT.

The Corolla stops much shorter than the K5:

The Corolla’s standard tires provide better handling because they have a lower 55 series profile (height to width ratio) that provides a stiffer sidewall than the K5 LXS’ standard 65 series tires.

The Corolla handles at .89 G’s, while the K5 EX pulls only .85 G’s of cornering force in a Car and Driver skidpad test.

The Corolla is 10.6 inches shorter than the K5, making the Corolla easier to handle, maneuver and park in tight spaces.

A low lift-over trunk design makes loading and unloading the Corolla easier. The Corolla’s trunk lift-over height is 27.1 inches, while the K5’s liftover is 28.6 inches.

The Corolla’s front and rear power windows all open or close fully with one touch of the switches, making it more convenient at drive-up windows and toll booths, or when talking with someone outside the car. The K5’s standard passenger windows don’t open or close automatically.

If the windows are left open on the Corolla the driver can close them all at the outside door handle. On a hot day the driver can lower the windows at the outside door handle or from a distance using the keyless remote. (This window function must be activated by your Toyota service department.) The driver of the K5 can only operate the windows from inside the vehicle, with the ignition on.

To help drivers see further while navigating curves, the Corolla XLE/XSE offers optional adaptive headlights to illuminate around corners automatically by reading vehicle speed and steering wheel angle. The K5 doesn’t offer cornering lights.

The Toyota Corolla comes in sedan, four door hatchback and four door bodystyles; the Kia K5 isn’t available as a four door hatchback or wagon.

Consumer Reports® recommends both the Toyota Corolla and the Kia K5, based on reliability, safety and performance.

The Toyota Corolla outsold the Kia K5 by over four to one during 2022.
