Both the EV6 and Leaf have child safety locks to prevent children from opening the rear doors. The EV6 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.

In a Vehicle-to-Vehicle Frontal Crash Prevention 2.0 test conducted by the Insurance Institute for Highway Safety (IIHS), the Kia EV6 achieved a “Acceptable” rating - the second highest possible - for its performance in forward collision warning and automatic braking systems, demonstrating its excellent capabilities in preventing collisions. The Nissan Leaf has not been tested.

The EV6 Long Range 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 EV6 and Leaf have rear cross-traffic warning, but the EV6 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 EV6 and the Leaf have standard driver and passenger frontal airbags, front and rear side-impact airbags, driver knee airbags, side-impact head airbags, front 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 35 MPH front crash tests on new vehicles. In this test, results indicate that the Kia EV6 is safer than the Nissan Leaf:

	EV6	Leaf
OVERALL STARS	5 Stars	4 Stars

Instrumented handling tests conducted by the National Highway Traffic Safety Administration and analysis of its dimensions indicate that the EV6, with its five-star roll-over rating, is 2.5% less likely to roll over than the Leaf, which received a four-star rating.

Warranty

The EV6 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.

Kia’s powertrain warranty covers the EV6 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.

Reliability

J.D. Power and Associates’ 2025 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that Kia vehicles are more reliable than Nissan vehicles. J.D. Power ranks Kia above average in long-term dependability. With 6 more problems per 100 vehicles in the first three years of ownership, Nissan is rated below average.

Engine

The EV6 has more powerful engines than the Leaf:

	Horsepower	Torque
EV6 Light Standard Range electric motor	167 HP	258 lbs.-ft.
EV6 Long Range electric motor	225 HP	258 lbs.-ft.
EV6 Long Range electric motors	320 HP	446 lbs.-ft.
Leaf electric motor	147 HP	236 lbs.-ft.
Leaf PLUS electric motor	214 HP	250 lbs.-ft.

As tested in Car and Driver the EV6 Long Range electric motors is faster than the Leaf PLUS:

	EV6	Leaf

		20" Wheels Electric Motors	270 miles
Leaf
	FWD	SV PLUS Electric Motor	212 miles
		Electric Motor	149 miles

Brakes and Stopping

For better stopping power the EV6’s brake rotors are larger than those on the Leaf:

	EV6	Leaf
Front Rotors	12.8 inches	11.1 inches
Rear Rotors	12.8 inches	11.5 inches

The EV6 stops much shorter than the Leaf:

	EV6	Leaf
70 to 0 MPH	181 feet	191 feet	Car and Driver
60 to 0 MPH	126 feet	141 feet	Consumer Reports
60 to 0 MPH (Wet)	136 feet	145 feet	Consumer Reports

Tires and Wheels

For better traction, the EV6 has larger standard tires than the Leaf (235/55R19 vs. 205/55R16). The EV6 GT-Line e-AWD’s optional tires are larger than the largest tires available on the Leaf (255/45R20 vs. 215/50R17).

The EV6 GT-Line e-AWD’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 Leaf SV PLUS’ 50 series tires.

For better ride, handling and brake cooling the EV6 has standard 19-inch wheels. Smaller 16-inch wheels are standard on the Leaf S. The EV6 GT-Line e-AWD’s optional 20-inch wheels are larger than the 17-inch wheels on the Leaf SV PLUS.

Suspension and Handling

For superior ride and handling, the Kia EV6 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 EV6’s wheelbase is 7.9 inches longer than on the Leaf (114.2 inches vs. 106.3 inches).

For better handling and stability, the average track (width between the wheels) on the EV6 is 3.7 inches wider in the front and 3.5 inches wider in the rear than the average track on the Leaf.

The EV6 Wind e-AWD handles at .85 G’s, while the Leaf pulls only .78 G’s of cornering force in a Car and Driver skidpad test.

Chassis

The front grille of the EV6 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 EV6 has 10.6 cubic feet more passenger volume than the Leaf (103 vs. 92.4).

The EV6 has .3 inches more front legroom, 3.2 inches more front hip room, 3.5 inches more front shoulder room, .7 inches more rear headroom, 5.5 inches more rear legroom, 3.2 inches more rear hip room and 3.1 inches more rear shoulder room than the Leaf.

For enhanced passenger comfort on long trips the EV6’s rear seats recline. The Leaf’s rear seats don’t recline.

Cargo Capacity

Pulling a handle automatically lowers the EV6’s rear seats, to make changing between passengers and cargo easier. The Leaf doesn’t offer automatic folding seats.

To make loading and unloading groceries and cargo easier when your hands are full, the EV6 Wind/GT-Line’s power liftgate can be opened just by waiting momentarily behind the back bumper, leaving your hands completely free. The EV6’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 EV6 offers up to a 2300 lbs. towing capacity. The Leaf has no towing capacity.

Servicing Ease

The EV6 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 EV6 Wind/GT-Line/GT, the memory system makes it convenient for both. Each setting activates different, customized memories for the driver’s seat position, steering wheel position (with optional power wheel adjuster) and outside mirror angle. The Leaf doesn’t offer a memory system.

The EV6 Light/Wind/GT-Line’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 EV6 GT-Line 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 EV6’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 EV6 and the Leaf have locks to prevent small children from operating them. When the lock on the EV6 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 EV6 GT-Line’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 EV6’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 EV6’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 EV6’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 Leaf’s intermittent wipers change speed with vehicle speed, but can’t turn on and off or change speed based on changing rainfall.

The EV6’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.

The EV6’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 EV6 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.

Both the Kia EV6 and Nissan Leaf offer exterior mirrors that can be folded to provide convenience. The EV6 features standard power folding mirrors, which allow for easy, one-touch folding or unfolding at the driver’s discretion. This provides added convenience when maneuvering or parking, as well as when walking past the parked vehicle. In comparison, the Leaf’s foldable mirrors are manual, requiring the driver to get out and physically fold them once parked and unfold them before getting in.

The EV6 has standard heated front seats. Heated front seats are only available on the Leaf SV PLUS. The EV6 also offers optional heated rear seats to keep those passengers extremely comfortable in the winter. Heated rear seats aren’t available in the Leaf.

Standard air-conditioned seats in the EV6 Wind/GT-Line 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 EV6 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 EV6’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 EV6 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 Kia EV6 has a standard wireless phone charging system (Qi) in the front center console. The Leaf doesn’t offer wireless personal charging.

The EV6 offers an optional 115-volt a/c outlet on the rear seat, allowing you to recharge a laptop or run small household appliances without special adapters that can break or get misplaced. The Leaf doesn’t offer a house-current electrical outlet.

The EV6 GT-Line’s Smart Parking Assist can parallel park or back into a parking spot by itself, starting, stopping and changing direction automatically. Remote Smart 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.

Recommendations

The EV6 was chosen as a Car and Driver’s “Top Ten” for 2023. The Leaf has never been chosen by Car and Driver in their “10Best” issue.

A group of representative automotive journalists from North America selected the EV6 as the 2023 North American Utility Vehicle of the Year. The Leaf has never been chosen.

The Kia EV6 outsold the Nissan Leaf by almost three to one during 2025.
