The Toyota Mirai has standard driver and front passenger side knee airbags mounted low on the dashboard. These airbags help prevent the driver and front passenger from sliding under their seatbelts or the main frontal airbags; this keeps them better positioned during a collision for maximum protection. Knee airbags also help keep the legs from striking the dashboard, preventing knee and leg injuries in the case of a serious frontal collision. The Kona Electric doesn’t offer knee airbags.

The Mirai has standard Whiplash Injury Lessening Seats (WIL), which use a specially designed headrest to protect the driver and front passenger from whiplash. During a rear-end collision, the WIL system moves the headrests forward to prevent neck and spine injuries. The Kona Electric doesn’t offer a whiplash protection system.

The Mirai 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 Kona Electric 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 Mirai and the Kona Electric have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front and rear seatbelt pretensioners, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems, blind spot warning systems, rearview cameras, rear cross-path warning and driver alert monitors.

Warranty

There are over 45 percent more Toyota dealers than there are Hyundai dealers, which makes it easier should you ever need service under the Mirai’s warranty.

Reliability

J.D. Power and Associates’ 2024 survey of the owners of three-year-old vehicles provides the statistics that show that Toyota vehicles are more reliable than Hyundai vehicles. J.D. Power ranks Toyota second in reliability, above the industry average. With 51 more problems per 100 vehicles, Hyundai is ranked 13th.

From surveys of all its subscribers, Consumer Reports’ March 2025 Auto Issue reports that Toyota vehicles are more reliable than Hyundai vehicles. Consumer Reports ranks Toyota third in overall reliability. Hyundai is ranked 10th.

Engine

The Mirai’s electric motor produces 49 more horsepower (182 vs. 133) and 33 lbs.-ft. more torque (221 vs. 188) than the Kona Electric SE’s standard electric motor. The Mirai’s electric motor produces 33 lbs.-ft. more torque (221 vs. 188) than the Kona Electric SEL/Limited/N-Line’s standard electric motor.

Fuel Economy and Range

The Mirai can travel longer on a full tank of hydrogen than the Kona Electric on a full charge:

		Miles
Mirai
	Electric Motor	402 miles
Kona Electric
	SEL/Limited Electric Motor	261 miles
	N-Line Electric Motor	230 miles
	SE Electric Motor	200 miles

Brakes and Stopping

The Mirai’s standard front and rear disc brakes are vented to help dissipate heat for shorter stops with less fading. The rear discs on the Kona Electric are solid, not vented.

Tires and Wheels

For better traction, the Mirai has larger tires than the Kona Electric (235/55R19 vs. 215/60R17).

The Mirai’s tires provide better handling because they have a lower 55 series profile (height to width ratio) that provides a stiffer sidewall than the Kona Electric’s standard 60 series tires.

For better ride, handling and brake cooling the Mirai has standard 19-inch wheels. Smaller 17-inch wheels are standard on the Kona Electric.

Suspension and Handling

For a smoother ride and more stable handling, the Mirai’s wheelbase is 10.2 inches longer than on the Kona Electric (114.9 inches vs. 104.7 inches).

The Mirai’s front to rear weight distribution is more even (49% to 51%) than the Kona Electric’s (56% to 44%). This gives the Mirai more stable handling and braking.

The Mirai XLE handles at .84 G’s, while the Kona Electric Limited pulls only .79 G’s of cornering force in a Motor Trend skidpad test.

Passenger Space

The Mirai has .5 inches more front legroom, 2.2 inches more front hip room, 1.9 inches more front shoulder room and .4 inches more rear hip room than the Kona Electric.

Cargo Capacity

With its sedan body style, valet key and remote trunk release lockout, the Mirai offers cargo security. The Kona Electric’s sport utility bodystyle defeats cargo security.

A standard locking glovebox (which can’t be accessed with the valet key) keeps your small valuables safer in the Mirai. The Kona Electric doesn’t offer locking storage for small valuables.

Ergonomics

The Mirai Limited has a standard heads-up display that projects speed and navigation instruction readouts in front of the driver’s line of sight, allowing drivers to view information without diverting their eyes from the road. The Kona Electric doesn’t offer a heads-up display.

The Mirai’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 Kona Electric’s standard power window switches have to be held the entire time to close them fully. Only its driver’s window opens automatically. With the Kona Electric N-Line/Limited’s power windows, only the front windows open or close automatically.

If the windows are left open on the Mirai 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 Kona Electric can only operate the windows from inside the vehicle, with the ignition on.

The Mirai’s standard Smart Key System allows you to unlock the doors from any outside door handle, open the trunk, and start the car, all without removing the key from the pocket or purse. Proximity Key standard on the Kona Electric doesn’t offer a sensor on the rear doors, so you’ll have to reach a front handle to unlock the rear door.

The Mirai Limited’s standard wipers adjust their speed and turn on and off automatically according to the amount of rainfall on the windshield. The Kona Electric’s manually variable intermittent wipers have to be constantly adjusted.

A power rear sunshade and manual rear side window sunshades are standard in the Mirai Limited to help block heat and glare for the rear passengers. The Kona Electric doesn’t offer a rear or rear side window sunshades.

When the Mirai Limited is put in reverse, both rearview mirrors tilt from their original position. This gives the driver a better view of the curb during parallel parking maneuvers. Shifting out of reverse puts the mirrors into their original positions. The Kona Electric’s mirrors don’t automatically adjust for backing.

The Mirai has standard heated front seats. Heated front seats are only available on the Kona Electric SEL/N-Line/Limited. The Mirai Limited also has standard heated rear seats to keep those passengers extremely comfortable in the winter. Heated rear seats aren’t available in the Kona Electric.

Both the Mirai and the Kona Electric offer rear vents. For greater rear passenger comfort, the Mirai has standard rear air conditioning vents to keep rear occupants cool in summer or warm in winter. The Kona Electric doesn’t offer rear air conditioning vents, only heat vents.

The Toyota Mirai has a standard Homelink wireless remote control system for garage door operation and device management, conveniently located on the rear view mirror. Homelink® eliminates the need for separate garage door openers and associated risks of losing, breaking, or having dead batteries. Hyundai charges extra for Homelink® on the Kona Electric.

To quickly and conveniently keep personal devices charged without cables tangling and wearing out, the Toyota Mirai has a standard wireless phone charging system (Qi) in the center console. Only the Kona Electric N-Line/Limited offers wireless charging.
