Safety

The Mirai’s optional pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Ioniq Electric doesn’t offer pre-crash pretensioners.

For enhanced safety, the front shoulder belts of the Toyota Mirai are height-adjustable, and the rear seat shoulder belts have child comfort guides to move the belt to properly fit children. A better fit can prevent injuries and the increased comfort also encourages children to buckle up. The Hyundai Ioniq Electric has only front height-adjustable seat belts.

The Mirai has standard Parking Assist Sonar to help warn the driver about vehicles, pedestrians or other obstacles behind or in front of their vehicle. The Ioniq Electric doesn’t offer a front parking aid.

Both the Mirai and the Ioniq Electric have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front seatbelt pretensioners, front wheel drive, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights and rearview cameras.

The Toyota Mirai weighs 911 pounds more than the Hyundai Ioniq Electric. The NHTSA advises that heavier cars are much safer in collisions than their significantly lighter counterparts. Crosswinds also affect lighter cars more.

Warranty

Toyota pays for scheduled maintenance on the Mirai for 3 years and 35000 miles. Toyota will pay for oil changes, lubrication and any other required maintenance. Hyundai doesn’t pay scheduled maintenance for the Ioniq Electric.

There are over 47 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’ December 2018 Auto Issue reports that Toyota vehicles are more reliable than Hyundai vehicles. Consumer Reports ranks Toyota second in reliability. Hyundai is ranked 10th.

The Mirai’s electric motor produces 33 more horsepower (151 vs. 118) and 32 lbs.-ft. more torque (247 vs. 215) than the Ioniq Electric’s electric motor.

A full recharge at a conventional charging station can take up to 4 hours and 25 minutes.

Car and Driver

Tires and Wheels

For better traction, the Mirai has larger tires than the Ioniq Electric (215/55R17 vs. 205/55R16).

For better ride, handling and brake cooling the Mirai has standard 17-inch wheels. Only 16-inch wheels are available on the Ioniq Electric.

Suspension and Handling

Cargo Capacity

With its sedan body style, valet key and remote trunk release lockout, the Mirai offers cargo security. The Ioniq Electric’s hatchback body style 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 Electric 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 Electric 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’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 Electric’s standard passenger windows don’t open or close automatically. With the Ioniq Electric’s optional power windows, only the front windows open or close automatically.

On a hot day the Mirai’s driver can lower all the windows from a distance using the keyless remote. The driver of the Ioniq Electric can only operate the windows from inside the vehicle, with the ignition on.

The Mirai’s rain-sensitive wipers adjust their speed and turn on and off automatically based on the amount of rainfall on the windshield. This allows the driver to concentrate on driving without constantly adjusting the wipers. The Ioniq Electric’s manually variable intermittent wipers have to be constantly adjusted.

While driving with high beams on, sensitive light sensors standard on the Mirai detect other vehicles which could be blinded and automatically switch to low beams. The Ioniq Electric doesn’t offer automatic dimming high beams.

When the Mirai 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 Electric’s mirrors don’t automatically adjust for backing.

The Mirai has standard automatic dimming rear and side view mirrors which automatically darken quickly when headlights shine on them, keeping following vehicles from blinding or distracting the driver. The Ioniq Electric offers an automatic rear view mirror, but its side mirrors don’t dim.

Both the Mirai and the Ioniq Electric have standard heated front seats. The Mirai also has standard heated rear seats to keep those passengers extremely comfortable in the winter. Heated rear seats aren’t available in the Ioniq Electric.

On extremely cold winter days, the Mirai’s standard heated steering wheel provides comfort, allowing the driver to steer safely and comfortably before the car heater warms up. The Ioniq Electric doesn’t offer a heated steering wheel.

Both the Mirai and the Ioniq 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 Ioniq Electric doesn’t offer rear air conditioning vents, only heat vents.
