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 Plug-In Hybrid 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 Plug-In Hybrid doesn’t offer a front passenger side knee airbag.

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 Plug-In Hybrid 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 Plug-In Hybrid 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.

Over 200 people are killed each year when backed over by motor vehicles. The Mirai offers an optional Parking Support Brake that uses rear sensors to monitor for objects to the rear and automatically applies the brakes to prevent a collision. The Ioniq Plug-In Hybrid doesn’t offer backup collision prevention brakes.

The Mirai offers an optional Bird’s Eye View Monitor to allow the driver to see objects all around the vehicle on a screen. The Ioniq Plug-In Hybrid 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.

To help make backing out of a parking space safer, the Mirai has standard Rear Cross Traffic Alert to warn the driver of approaching traffic and automatically engage the brakes to help avoid a collision. Hyundai charges extra for rear cross-path warning on the Ioniq Plug-In Hybrid.

Both the Mirai and the Ioniq Plug-In Hybrid have standard driver and passenger frontal airbags, front side-impact airbags, driver knee 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, rearview cameras and driver alert monitors.

The Toyota Mirai weighs 937 to 1017 pounds more than the Hyundai Ioniq Plug-In Hybrid. The NHTSA advises that heavier cars are much safer in collisions than their significantly lighter counterparts.

Warranty

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.

Reliability

From surveys of all its subscribers, Consumer Reports’ January 2023 Auto Issue reports that Toyota vehicles are more reliable than Hyundai vehicles. Consumer Reports ranks Toyota first in overall reliability. Hyundai is ranked 13th.

Engine

The Mirai’s electric motor produces 43 more horsepower (182 vs. 139) and 105 lbs.-ft. more torque (300 vs. 195) than the Ioniq Plug-In Hybrid’s 1.6 DOHC 4-cylinder hybrid.

Fuel Economy and Range

The Mirai can travel with zero emissions on a full tank of hydrogen for 357 to 402 miles. The Ioniq Plug-In Hybrid has to start its internal combustion engine after only 29 miles.

Environmental Friendliness

In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the Toyota Mirai higher (10 out of 10) than the Hyundai Ioniq Plug-In Hybrid (7). This means the Mirai produces up to 11.8 pounds less smog-producing pollutants than the Ioniq Plug-In Hybrid every 15,000 miles.

Brakes and Stopping

For better stopping power the Mirai’s brake rotors are larger than those on the Ioniq Plug-In Hybrid:

	Mirai	Ioniq Plug-In Hybrid
Front Rotors	11.6 inches	11 inches
Rear Rotors	11.4 inches	11.2 inches

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 Ioniq Plug-In Hybrid are solid, not vented.

Tires and Wheels

For better traction, the Mirai has larger standard tires than the Ioniq Plug-In Hybrid (235/55R19 vs. 205/55R16). The Mirai Limited’s optional tires are larger than the largest tires available on the Ioniq Plug-In Hybrid (245/45R20 vs. 205/55R16).

The Mirai Limited’s optional tires provide better handling because they have a lower 45 series profile (height to width ratio) that provides a stiffer sidewall than the Ioniq Plug-In Hybrid’s 55 series tires.

For better ride, handling and brake cooling the Mirai has standard 19-inch wheels. Only 16-inch wheels are available on the Ioniq Plug-In Hybrid. The Mirai Limited offers optional 20-inch wheels.

Suspension and Handling

The Mirai has standard front and rear gas-charged shocks for better control over choppy roads. The Ioniq Plug-In Hybrid’s suspension doesn’t offer rear gas-charged shocks.

For a smoother ride and more stable handling, the Mirai’s wheelbase is 8.6 inches longer than on the Ioniq Plug-In Hybrid (114.9 inches vs. 106.3 inches).

For better handling and stability, the track (width between the wheels) on the Mirai is 2.1 inches wider in the front and 1.3 inches wider in the rear than on the Ioniq Plug-In Hybrid.

Passenger Space

The Mirai has 2.7 inches more front hip room and 2.3 inches more front shoulder room than the Ioniq Plug-In Hybrid.

Cargo Capacity

With its sedan body style, valet key and remote trunk release lockout, the Mirai offers cargo security. The Ioniq Plug-In Hybrid’s hatchback body style, non-lockable folding seat and non-lockable remote release defeat 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 Plug-In Hybrid doesn’t offer locking storage for small valuables.

Servicing Ease

The Mirai uses gas struts to support the hood for easier service access. The Ioniq Plug-In Hybrid uses a prop rod to support its heavy hood. It takes two hands to open the hood and set the prop rod, the prop rod gets in the way during maintenance and service, and the prop rod could be knocked out, causing the heavy hood to fall on the person maintaining or servicing the car.

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 Ioniq Plug-In Hybrid 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 Ioniq Plug-In Hybrid’s standard passenger windows don’t open or close automatically. With the Ioniq Plug-In Hybrid’s optional 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 Plug-In Hybrid can only operate the windows from inside the vehicle, with the ignition on.

The Mirai’s power window, power lock, power mirror and cruise control switches are lit from behind, making them plainly visible and easier to operate at night. The Ioniq Plug-In Hybrid’s power mirror switches are unlit, making them difficult to find at night and operate safely.

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 Ioniq Plug-In Hybrid’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 Ioniq Plug-In Hybrid 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 Ioniq Plug-In Hybrid’s mirrors don’t automatically adjust for backing.

Both the Mirai and the Ioniq Plug-In Hybrid 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 Plug-In Hybrid.

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 Plug-In Hybrid doesn’t offer air-conditioned seats.

Both the Mirai and the Ioniq Plug-In Hybrid 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 Ioniq Plug-In Hybrid doesn’t offer rear air conditioning vents, only heat vents.

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. The Ioniq Plug-In Hybrid doesn’t offer wireless personal charging.

The Mirai Limited’s Intelligent Parking Assist can parallel park or back into a parking spot by itself, starting, stopping and changing direction automatically. The Ioniq Plug-In Hybrid doesn’t offer an automated parking system.
