Both the Ioniq 5 and Leaf have child safety locks to prevent children from opening the rear doors. The Ioniq 5 has power child safety locks, allowing the driver to activate and deactivate them from the driver's seat and to know when they're engaged. The Leaf’s child locks have to be individually engaged at each rear door with a manual switch. The driver can’t know the status of the locks without opening the doors and checking them.

The Ioniq 5 has all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The Leaf doesn’t offer all-wheel drive.

Both the Ioniq 5 and Leaf have rear cross-traffic warning, but the Ioniq 5 has Rear Cross-Traffic Collision-Avoidance Assist (automatically applies the brakes) to better prevent a collision when backing near traffic. The Leaf’s Rear Cross Traffic Alert doesn’t automatically brake.

Both the Ioniq 5 and the Leaf have standard driver and passenger frontal airbags, front and rear 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, lane departure warning systems, blind spot warning systems, rearview cameras, rear cross-path warning and available around view monitors.

The National Highway Traffic Safety Administration does side impact tests on new vehicles. In this test, which crashes the vehicle into a flat barrier at 38.5 MPH and into a post at 20 MPH, results indicate that the Hyundai Ioniq 5 is safer than the Nissan Leaf:

	Ioniq 5	Leaf
	Front Seat
STARS	5 Stars	5 Stars
HIC	75	131
Chest Movement	.7 inches	.8 inches
Abdominal Force	131 lbs.	137 lbs.
Hip Force	261 lbs.	377 lbs.
	Rear Seat

New test not comparable to pre-2011 test results. More stars = Better. Lower test results = Better.

Side impacts caused 23% of all road fatalities in 2018, down from 29% in 2003, when the Insurance Institute for Highway Safety introduced its side barrier test. In order to continue improving vehicle safety, the IIHS has started using a more severe side impact test: 37 MPH (up from 31 MPH), with a 4180-pound barrier (up from 3300 pounds). The results of this newly developed test demonstrates that the Hyundai Ioniq 5 is safer than the Leaf:

Instrumented handling tests conducted by the National Highway Traffic Safety Administration and analysis of its dimensions indicate that the Ioniq 5, with its five-star roll-over rating, is 2.4% less likely to roll over than the Leaf, which received a four-star rating.

The Hyundai Ioniq 5 has achieved the Insurance Institute for Highway Safety’s (IIHS) highest rating of “Top Safety Pick Plus” for the 2024 model year. This distinction is based on its exceptional performance in IIHS’ rigorous battery of safety tests. Specifically, it earned a “Good” rating in the latest, more stringent moderate overlap front crash test, a “Good” result in the updated side impact test, and an “Acceptable” score in the revised pedestrian crash prevention test. The Leaf is not even a standard “Top Safety Pick” for 2024.

Warranty

The Ioniq 5 comes with a full 5-year/60,000-mile basic warranty, which covers the entire truck and includes 24-hour roadside assistance. The Leaf’s 3-year/36,000-mile basic warranty expires 2 years or 24,000 miles sooner.

Hyundai’s powertrain warranty covers the Ioniq 5 5 years and 40,000 miles longer than Nissan covers the Leaf. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 10 years or 100,000 miles. Coverage on the Leaf ends after only 5 years or 60,000 miles.

The Ioniq 5’s corrosion warranty is 2 years longer than the Leaf’s (7 vs. 5 years).

Hyundai pays for scheduled maintenance on the Ioniq 5 for 3 years and 36,000 miles. Hyundai will pay for tire rotations, cabin filter replacement, brake fluid replacement, inspections, and any other required maintenance. Nissan doesn’t pay scheduled maintenance for the Leaf.

J.D. Power and Associates’ 2024 Initial Quality Study of new car owners surveyed provide the statistics that show that Hyundai vehicles are better in initial quality than Nissan vehicles. J.D. Power ranks Hyundai third in initial quality, above the industry average. With 4 more problems per 100 vehicles, Nissan is ranked 6th.

J.D. Power and Associates’ 2024 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that Hyundai vehicles are more reliable than Nissan With 1 fewer problems per 100 vehicles in the first three years of ownership, J.D. Power ranks Hyundai higher than Nissan.

From surveys of all its subscribers, Consumer Reports’ January 2024 Auto Issue reports that Hyundai vehicles are more reliable than Nissan vehicles. Consumer Reports ranks Hyundai 6 places higher in reliability than Nissan.

Tires and Wheels

For better traction, the Ioniq 5 has larger standard tires than the Leaf (235/55R19 vs. 205/55R16). The Ioniq 5 Limited AWD’s tires are larger than the largest tires available on the Leaf (255/45R20 vs. 215/50R17).

The Ioniq 5 Limited AWD’s tires provide better handling because they have a lower 45 series profile (height to width ratio) that provides a stiffer sidewall than the Leaf SV PLUS’ 50 series tires.

For better ride, handling and brake cooling the Ioniq 5 has standard 19-inch wheels. Smaller 16-inch wheels are standard on the Leaf S. The Ioniq 5 Limited AWD’s 20-inch wheels are larger than the 17-inch wheels on the Leaf SV PLUS.

Suspension and Handling

For superior ride and handling, the Hyundai Ioniq 5 has fully independent front and rear suspensions. An independent suspension allows the wheels to follow the road at the best angle for gripping the pavement, without compromising ride comfort. The Nissan Leaf has a rear torsion beam axle, with a semi-independent rear suspension.

For a smoother ride and more stable handling, the Ioniq 5’s wheelbase is 11.8 inches longer than on the Leaf (118.1 inches vs. 106.3 inches).

For better handling and stability, the average track (width between the wheels) on the Ioniq 5 is 4 inches wider in the front and 3.8 inches wider in the rear than the average track on the Leaf.

The Ioniq 5’s front to rear weight distribution is more even (51% to 49%) than the Leaf’s (57.3% to 42.7%). This gives the Ioniq 5 more stable handling and braking.

The Ioniq 5 Limited AWD handles at .88 G’s, while the Leaf pulls only .76 G’s of cornering force in a Motor Trend skidpad test.

Chassis

The front grille of the Ioniq 5 uses electronically controlled shutters to close off airflow and reduce drag when less engine cooling is needed. This helps improve highway fuel economy. The Leaf doesn’t offer active grille shutters.

Passenger Space

The Ioniq 5 has 14.1 cubic feet more passenger volume than the Leaf (106.5 vs. 92.4).

The Ioniq 5 has 2.2 inches more front hip room, 3.4 inches more front shoulder room, 1.4 inches more rear headroom, 5.9 inches more rear legroom, 3.6 inches more rear hip room and 5.2 inches more rear shoulder room than the Leaf.

For enhanced passenger comfort on long trips the Ioniq 5’s rear seats recline. The Leaf’s rear seats don’t recline.

Cargo Capacity

To make loading and unloading groceries and cargo easier when your hands are full, the Ioniq 5 SEL/Limited’s power liftgate can be opened just by waiting momentarily behind the back bumper, leaving your hands completely free. The Ioniq 5’s power liftgate can also be opened or closed by pressing a button. The Leaf doesn’t offer a power or hands-free opening liftgate.

Towing

The Ioniq 5 offers up to a 2300 lbs. towing capacity. The Leaf has no towing capacity.

Servicing Ease

The Ioniq 5 uses gas struts to support the hood for easier service access. The Leaf 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

When two different drivers share the Ioniq 5 Limited, the memory seats and mirrors make it convenient for both. Each setting activates different, customized memories for the driver’s seat position and outside mirror angle. The Leaf doesn’t offer a memory system.

The Ioniq 5 Limited’s standard easy entry system glides the driver’s seat back when the door is unlocked or the ignition is switched off, making it easier for the driver to get in and out. The Leaf doesn’t offer an easy entry system.

The Ioniq 5 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 Leaf doesn’t offer a heads-up display.

The Ioniq 5’s power parking brake sets with one touch and releases with one touch or automatically. The Leaf’s parking brake has to be released manually.

The power windows standard on both the Ioniq 5 and the Leaf have locks to prevent small children from operating them. When the lock on the Ioniq 5 is engaged the driver can still operate all of the windows, for instance to close one opened by a child. The Leaf prevents the driver from operating the other windows just as it does the other passengers.

The Ioniq 5 SEL/Limited’s front power windows open fully with one touch of the switches, and the driver’s window also automatically closes, making it more convenient at drive-up windows and toll booths, or when talking with someone outside the car. The Leaf’s passenger windows don’t open or close automatically.

On a hot day the Ioniq 5’s driver can lower the front windows from a distance using the keyless remote. The driver of the Leaf can only operate the windows from inside the vehicle, with the ignition on.

The Ioniq 5’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 Leaf’s power window (except driver window) and power lock switches are unlit, making them difficult to find at night and operate safely.

The Ioniq 5 Limited’s standard wipers adjust their speed and turn on and off automatically according to the amount of rainfall on the windshield. The Leaf’s intermittent wipers change speed with vehicle speed, but can’t turn on and off or change speed based on changing rainfall.

The Ioniq 5’s LED headlights produce a whiter, brighter light (up to 3x) using five times less power than the Leaf S’ standard halogen headlights. LED lights also light instantly and last over twenty times longer than halogen.

Manual rear side window sunshades are available in the Ioniq 5 to help block heat and glare for the rear passengers. The Leaf doesn’t offer rear side window sunshades.

The Ioniq 5’s standard outside mirrors include heating elements to clear off the mirrors for better visibility. Nissan only offers heated mirrors on the Leaf SV PLUS.

When the Ioniq 5 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 Leaf’s mirrors don’t automatically adjust for backing.

Standard air-conditioned seats in the Ioniq 5 Limited keep the driver and front passenger comfortable and take the sting out of hot seats in Summer. The Leaf doesn’t offer air-conditioned seats.

The Ioniq 5 Limited has a standard center folding armrest for the rear passengers. A center armrest helps make rear passengers more comfortable and it can provide a boundary between children. The Leaf doesn’t offer a rear seat center armrest.

The Ioniq 5’s standard dual zone air conditioning allows the driver and front passenger to choose two completely different temperatures so people with different temperature preferences won’t have to compromise. This makes both the driver and front passenger as comfortable as possible. The Leaf doesn’t offer dual zone air conditioning.

For greater rear passenger comfort, the Ioniq 5 SEL/Limited has standard rear a/c vents to keep rear occupants more comfortable. The Leaf doesn’t offer rear vents.

To quickly and conveniently keep personal devices charged without cables tangling and wearing out, the Hyundai Ioniq 5 SEL/Limited has a standard wireless phone charging system (Qi) in the front center console. The Leaf doesn’t offer wireless personal charging.

The Ioniq 5 Limited’s Parking Assist can parallel park or back into a parking spot by itself, starting, stopping and changing direction automatically. Remote Parking Assist will park and retrieve your car remotely: press a button and watch it park itself. This is ideal for tight locations. The Leaf doesn’t offer an automated parking system.

Economic Advantages

The Ioniq 5 will cost the buyer less in the long run because of its superior resale value. The IntelliChoice estimates that the Ioniq 5 will retain 46.72% to 48.8% of its original price after five years, while the Leaf only retains 41.06% to 42.25%.

Recommendations

The Ioniq 5 was chosen as a Car and Driver’s “Top Ten” for 2024 and 2 more times in the last 3 years. The Leaf has never been chosen by Car and Driver in their “10Best” issue.

The Hyundai Ioniq 5 outsold the Nissan Leaf by almost five to one during 2023.
