Compare the2023 Toyota MiraiVS 2023 Hyundai Ioniq 5

For enhanced safety, the front and rear seat shoulder belts of the Toyota Mirai have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision and force limiters to limit the pressure the belts will exert on the passengers. The Hyundai Ioniq 5 doesn’t offer pretensioners for its rear seat belts.

The Toyota Mirai has standard driver and front passenger side knee airbags mounted low on the dashboard. These airbags helps 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 Ioniq 5 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 Ioniq 5 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 Ioniq 5 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 Ioniq 5 have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, 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, driver alert monitors and available around view monitors.

There are over 49 percent more Toyota dealers than there are Hyundai dealers, which makes it easier should you ever need service under the Mirai’s warranty.

With its sedan body style, valet key and remote trunk release lockout, the Mirai offers cargo security. The Ioniq 5’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 Ioniq 5 doesn’t offer locking storage for small valuables.

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 Ioniq 5’s standard passenger windows don’t open or close automatically. With the Ioniq 5 SEL/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 Ioniq 5 can only close the windows from inside the vehicle, with the ignition on.

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 Ioniq 5 doesn’t offer a rear sunshade.

Both the Mirai and the Ioniq 5 have standard heated front seats. 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 Ioniq 5.

Standard air conditioned seats in the front and rear seats keep the Mirai Limited’s passengers comfortable and take the sting out of hot leather in summer. The Ioniq 5 doesn’t offer air-conditioned seats in the rear.

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 Ioniq 5 SEL/Limited offers wireless charging.
