Compare the2025 Nissan LeafVS 2025 Hyundai Ioniq 6

The Nissan Leaf 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 6 doesn’t offer knee airbags.

The Leaf has standard Active Head Restraints, which use a specially designed headrest to protect the driver and front passenger from whiplash. During a rear-end collision, the Active Head Restraints system moves the headrests forward to prevent neck and spine injuries. The Ioniq 6 doesn’t offer a whiplash protection system.

Both the Leaf and the Ioniq 6 have standard driver and passenger frontal airbags, front 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, available daytime running lights, around view monitors and driver alert monitors.

There are over 28 percent more Nissan dealers than there are Hyundai dealers, which makes it easier should you ever need service under the Leaf’s warranty.

The Leaf’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 6 are solid, not vented.

The Nissan Leaf may be more efficient, handle and accelerate better because it weighs about 450 to 700 pounds less than the Hyundai Ioniq 6.

A maintenance reminder system is standard on the Leaf to save the owner time and money by calculating maintenance intervals for tire rotation, based on odometer mileage. This takes the guesswork out of keeping your vehicle in top condition and helps it last longer. Hyundai doesn’t offer a maintenance reminder on the Ioniq 6.

The Leaf’s standard power window controls are mounted on the armrest for easy access. The Ioniq 6’s available power window controls are spread out on the center console where they can’t be seen without the driver completely removing his eyes from the road.

The Leaf’s speed-sensitive wipers speed up when the vehicle does, so that the driver doesn’t have to continually adjust the speed of the wipers. The Ioniq 6’s standard manually variable intermittent wipers have to be constantly adjusted.

To improve rear visibility by keeping the rear window clear, the Leaf has a standard rear wiper. The Ioniq 6 doesn’t offer a rear wiper.

The Leaf’s power mirror controls are mounted on the armrest for easy access. The Ioniq 6’s power mirror controls are on the dash where they are possibly hidden by the steering wheel and are awkward to manipulate.
