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

Over 200 people are killed each year when backed over by motor vehicles. The Avalon Hybrid Limited offers optional Rear Cross-Traffic Braking that uses rear sensors to monitor and automatically apply the brakes to prevent a rear collision. The Ioniq Hybrid doesn’t offer backup collision prevention brakes.

The Avalon Hybrid Limited offers an optional Bird’s Eye View Camera to allow the driver to see objects all around the vehicle on a screen. The Ioniq Hybrid only offers a rear monitor and rear parking sensors that beep or flash a light. That doesn’t help with obstacles to the front or sides.

Both the Avalon Hybrid and the Ioniq Hybrid 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, plastic fuel tanks, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding and rearview cameras.

The Toyota Avalon Hybrid weighs 523 to 719 pounds more than the Hyundai Ioniq Hybrid. The NHTSA advises that heavier cars are much safer in collisions than their significantly lighter counterparts. Crosswinds also affect lighter cars more.

For its top level performance in IIHS driver and passenger-side small overlap frontal, moderate overlap frontal, side impact, roof strength and head restraint tests, with its optional front crash prevention system, and its headlight’s “Good” rating, the Insurance Institute for Highway Safety grants the Avalon Hybrid its highest rating: “Top Pick Plus” for 2019, a rating granted to only 45 vehicles tested by the IIHS. The Ioniq Hybrid is only a standard “Top Pick” for 2019.


Toyota pays for scheduled maintenance on the Avalon Hybrid for 2 years and 25000 miles. Toyota will pay for oil changes, lubrication and any other required maintenance. Hyundai doesn’t pay scheduled maintenance for the Ioniq Hybrid.

There are over 47 percent more Toyota dealers than there are Hyundai dealers, which makes it easier should you ever need service under the Avalon Hybrid’s warranty.


J.D. Power and Associates’ 2019 survey of the owners of three-year-old vehicles provides the long-term dependability 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 16 more problems per 100 vehicles, Hyundai is ranked 8th.

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 Avalon Hybrid’s 2.5 DOHC 4 cyl. hybrid produces 76 more horsepower (215 vs. 139) than the Ioniq Hybrid’s 1.6 DOHC 4 cyl. hybrid.

Fuel Economy and Range

The Avalon Hybrid has 1.3 gallons more fuel capacity than the Ioniq Hybrid (13.2 vs. 11.9 gallons), for longer range between fill-ups.


The Avalon Hybrid 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 Ioniq Hybrid doesn’t offer a CVT.

Brakes and Stopping

For better stopping power the Avalon Hybrid’s brake rotors are larger than those on the Ioniq Hybrid:




Front Rotors

12 inches

11 inches

Rear Rotors

11.06 inches

10.3 inches

Tires and Wheels

For better traction, the Avalon Hybrid has larger standard tires than the Ioniq Hybrid (215/55R17 vs. 195/65R15). The Avalon Hybrid Limited’s tires are larger than the largest tires available on the Ioniq Hybrid (235/40R18 vs. 225/45R17).

The Avalon Hybrid XLE’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 Ioniq Hybrid’s standard 65 series tires. The Avalon Hybrid Limited’s tires have a lower 40 series profile than the Ioniq Hybrid Limited’s optional 45 series tires.

For better ride, handling and brake cooling the Avalon Hybrid XLE has standard 17-inch wheels. Smaller 15-inch wheels are standard on the Ioniq Hybrid. The Avalon Hybrid Limited’s 18-inch wheels are larger than the 17-inch wheels optional on the Ioniq Hybrid Limited.

The Avalon Hybrid has a standard space-saver spare tire so you can replace a flat tire and drive to have the flat repaired or replaced. A spare tire isn’t available on the Ioniq Hybrid; it requires you to depend on roadside assistance and your vehicle will have to be towed.

Suspension and Handling

For a smoother ride and more stable handling, the Avalon Hybrid’s wheelbase is 6.7 inches longer than on the Ioniq Hybrid (113 inches vs. 106.3 inches).

For better handling and stability, the average track (width between the wheels) on the Avalon Hybrid is 1.4 inches wider in the front and 1.8 inches wider in the rear than the average track on the Ioniq Hybrid.

Passenger Space

The Avalon Hybrid has 7.6 cubic feet more passenger volume than the Ioniq Hybrid (103.8 vs. 96.2).

The Avalon Hybrid has 2 inches more front hip room, 2.2 inches more front shoulder room, .5 inches more rear headroom, 4.7 inches more rear legroom, 1.9 inches more rear hip room and 2.1 inches more rear shoulder room than the Ioniq Hybrid.

Cargo Capacity

A standard locking glovebox keeps your small valuables safer in the Avalon Hybrid. The Ioniq Hybrid doesn’t offer locking storage for small valuables.

Servicing Ease

The Avalon Hybrid uses gas struts to support the hood for easier service access. The Ioniq 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.


The Avalon Hybrid’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 Hybrid’s standard passenger windows don’t open or close automatically. With the Ioniq Hybrid Limited’s power windows, only the front windows open or close automatically.

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

The Insurance Institute for Highway Safety (IIHS) conducts detailed tests on headlights for their range both straight ahead and in curves and to be certain they don’t exceed acceptable amounts of glare to oncoming drivers. The Avalon Hybrid’s available headlights were rated “Good” by the IIHS, while the Ioniq Hybrid’s headlights are rated “Acceptable” to “Poor.”

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

The Avalon Hybrid’s standard outside mirrors include heating elements to clear off the mirrors for better visibility. Hyundai only offers heated mirrors on the Ioniq Hybrid SEL/Limited.

When the Avalon Hybrid Limited/Touring 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 Hybrid’s mirrors don’t automatically adjust for backing.

The Avalon Hybrid Limited 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 Hybrid offers an automatic rear view mirror, but its side mirrors don’t dim.

The Avalon Hybrid has standard heated front seats. Heated front seats are only available on the Ioniq Hybrid SEL/Limited. The Avalon Hybrid 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 Hybrid.

Standard air-conditioned seats in the Avalon Hybrid Limited keep the driver and front passenger comfortable and take the sting out of hot seats in summer. The Ioniq Hybrid doesn’t offer air-conditioned seats.

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

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


The Toyota Avalon outsold the Hyundai Ioniq by over two to one during 2018.
