Both the EV9 and Ascent have child safety locks to prevent children from opening the rear doors. The EV9 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 Ascent’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 EV9 has a standard front seat center airbag, which deploys between the driver and front passenger, protecting them from injuries caused by striking each other in serious side impacts. The Ascent doesn’t offer front seat center airbags.

In a Vehicle-to-Vehicle Frontal Crash Prevention 2.0 test conducted by the Insurance Institute for Highway Safety (IIHS), the Kia EV9 achieved a “Good” rating - the highest possible - for its performance in forward collision warning and automatic braking systems, demonstrating its excellent capabilities in preventing collisions. The Subaru Ascent has not been tested.

Both the EV9 and Ascent have rear cross-traffic warning, but the EV9 has Rear Cross-Traffic Collision-Avoidance Assist (automatically applies the brakes) to better prevent a collision when backing near traffic. The Ascent’s Rear Cross Traffic Alert doesn’t automatically brake.

Both the EV9 and the Ascent have standard driver and passenger frontal airbags, front side-impact airbags, driver knee 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, daytime running lights, lane departure warning systems, blind spot warning systems, rearview cameras, rear cross-path warning and available around view monitors.

The Kia EV9 weighs 503 to 1407 pounds more than the Subaru Ascent. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.

The Insurance Institute for Highway Safety does 40 MPH moderate front offset crash tests on new cars. In this updated test, results indicate that the EV9 is safer than the Ascent:

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 Kia EV9 is safer than the Ascent:

The Kia EV9 has achieved the Insurance Institute for Highway Safety’s (IIHS) highest rating of “Top Safety Pick Plus” for the 2025 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 a “Good” score in the revised pedestrian crash prevention test. The Ascent is only a standard “Top Safety Pick” for 2025.

Warranty

The EV9 comes with a full 5-year/60,000-mile basic warranty, which covers the entire truck and includes 24-hour roadside assistance. The Ascent’s 3-year/36,000-mile basic warranty expires 2 years or 24,000 miles sooner.

Kia’s powertrain warranty covers the EV9 5 years and 40,000 miles longer than Subaru covers the Ascent. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 10 years or 100,000 miles. Coverage on the Ascent ends after only 5 years or 60,000 miles.

There are over 24 percent more Kia dealers than there are Subaru dealers, which makes it easier should you ever need service under the EV9’s warranty.

Reliability

J.D. Power and Associates’ 2024 Initial Quality Study of new car owners surveyed provide the statistics that show that Kia vehicles are better in initial quality than Subaru vehicles. J.D. Power ranks Kia fourth in initial quality, above the industry average. With 20 more problems per 100 vehicles, Subaru is ranked 12th.

J.D. Power and Associates’ 2024 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that Kia vehicles are more reliable than Subaru vehicles. J.D. Power ranks Kia above average in long-term dependability. With 3 more problems per 100 vehicles in the first three years of ownership, Subaru is rated below average.

Engine

The EV9 Land/Wind’s standard electric motors produces 119 more horsepower (379 vs. 260) and 166 lbs.-ft. more torque (443 vs. 277) than the Ascent’s 2.4 turbo 4-cylinder. The EV9 GT-Line’s standard electric motors produces 119 more horsepower (379 vs. 260) and 239 lbs.-ft. more torque (516 vs. 277) than the Ascent’s 2.4 turbo 4-cylinder.

As tested in Consumer Reports the Kia EV9 is faster than the Subaru Ascent:

	EV9 Land/Wind	EV9 GT-Line	Ascent
Zero to 30 MPH	2.1 sec	1.6 sec	3.3 sec
Zero to 60 MPH	5.3 sec	4.5 sec	8 sec
45 to 65 MPH Passing	3 sec	1.9 sec	4.8 sec
Quarter Mile	14 sec	13.3 sec	16.4 sec
Speed in 1/4 Mile	101 MPH	101 MPH	88 MPH

As tested in Motor Trend the EV9 GT-Line electric motors is faster than the Subaru Ascent (base engine):

	EV9	Ascent
Zero to 60 MPH	4.4 sec	7.5 sec
Quarter Mile	13.2 sec	16 sec
Speed in 1/4 Mile	102 MPH	88.6 MPH

Fuel Economy and Range

On the EPA test cycle the EV9 gets better mileage than the Ascent:

			MPGe
EV9
	RWD	Light Long Range Electric Motor	100 city/78 hwy
		Light Electric Motor	99 city/77 hwy
	AWD	Land/Wind Electric Motors	91 city/75 hwy
		GT-Line Electric Motors	88 city/72 hwy
Ascent
			MPG
	AWD	2.4 turbo flat-4	20 city/26 hwy
		Limited/Touring/Onyx 2.4 turbo flat-4	19 city/25 hwy

The EV9 can travel with zero emissions for 230 to 304 miles (dependent on model). The Ascent can’t move without running its internal combustion engine.

Regenerative brakes improve the EV9’s fuel efficiency by converting inertia back into energy instead of wasting it. The Ascent doesn’t offer a regenerative braking system.

The EV9, as a pure battery electric vehicle, has no need to “idle” its motors in traffic: they only burn power when moving. The EV9’s climate control systems still work completely when the vehicle is stopped. The Ascent still runs its internal combustion engine whenever it’s stopped, burning excess fuel.

Environmental Friendliness

In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the Kia EV9 higher (10 out of 10) than the Subaru Ascent (4). This means the EV9 produces up to 25 pounds less smog-producing pollutants than the Ascent every 15,000 miles.

Brakes and Stopping

For better stopping power the EV9’s brake rotors are larger than those on the Ascent:

	EV9	Ascent
Front Rotors	14.2 inches	13.1 inches
Rear Rotors	13.6 inches	13 inches

The EV9 stops shorter than the Ascent:

	EV9	Ascent
70 to 0 MPH	178 feet	179 feet	Car and Driver
60 to 0 MPH	118 feet	125 feet	Motor Trend

Tires and Wheels

For better traction, the EV9 has larger standard tires than the Ascent (255/60R19 vs. 245/60R18). The EV9 GT-Line’s tires are larger than the largest tires available on the Ascent (285/45R21 vs. 245/60R18).

The EV9 GT-Line’s tires provide better handling because they have a lower 45 series profile (height to width ratio) that provides a stiffer sidewall than the Ascent Onyx/Limited/Touring/Bronze’s 50 series tires.

For better ride, handling and brake cooling the EV9 has standard 19-inch wheels. Smaller 18-inch wheels are standard on the Ascent Premium. The EV9 GT-Line’s 21-inch wheels are larger than the 20-inch wheels on the Ascent Onyx/Limited/Touring/Bronze.

Suspension and Handling

The EV9 offers an optional automatic rear load leveling suspension to keep ride height level with a heavy load or when towing. The Ascent doesn’t offer a load leveling suspension.

The EV9 has vehicle speed sensitive variable-assist power steering, for low-effort parking, better control at highway speeds and during hard cornering, and a better feel of the road. The Ascent doesn’t offer variable-assist power steering.

The EV9’s drift compensation steering can automatically compensate for road conditions which would cause the vehicle to drift from side to side, helping the driver to keep the vehicle straight more easily. The Ascent doesn’t offer drift compensation steering.

For a smoother ride and more stable handling, the EV9’s wheelbase is 8.2 inches longer than on the Ascent (122 inches vs. 113.8 inches).

For better handling and stability, the average track (width between the wheels) on the EV9 is 2.4 inches wider in the front and 3.1 inches wider in the rear than the track on the Ascent.

The EV9’s front to rear weight distribution is more even (47.9% to 52.1%) than the Ascent’s (54.2% to 45.8%). This gives the EV9 more stable handling and braking.

The EV9 GT-Line AWD handles at .87 G’s, while the Ascent Limited pulls only .79 G’s of cornering force in a Car and Driver skidpad test.

The EV9 GT-Line AWD executes Motor Trend’s “Figure Eight” maneuver 1.1 seconds quicker than the Ascent Touring (26.3 seconds @ .69 average G’s vs. 27.4 seconds @ .63 average G’s).

Chassis

The front grille of the EV9 uses electronically controlled shutters to close off airflow and reduce drag when less engine cooling is needed. This helps improve highway fuel economy. The Ascent doesn’t offer active grille shutters.

As tested by Car and Driver, the interior of the EV9 GT-Line AWD is quieter than the Ascent Touring:

	EV9	Ascent
At idle	31 dB	40 dB
Full-Throttle	69 dB	73 dB
70 MPH Cruising	67 dB	67 dB

Passenger Space

The EV9 has 5.6 cubic feet more passenger volume than the Ascent (158.8 vs. 153.2).

The EV9 has 1.6 inches more front hip room, .5 inches more front shoulder room, 4.2 inches more rear legroom, .7 inches more rear hip room and 3.3 inches more third row headroom than the Ascent.

Cargo Capacity

The EV9’s cargo area provides more volume than the Ascent.

	EV9	Ascent
Behind Third Seat	20.2 cubic feet	17.8 cubic feet
Second Seat Folded	81.7 cubic feet	75.6 cubic feet

The EV9’s cargo area is larger than the Ascent’s in almost every dimension:

	EV9	Ascent
Length to seat (3rd/2nd/1st)	22”/51.1”/84”	20.3”/48”/82.9”
Max Width	52.3”	50.5”
Min Width	41.7”	45.9”
Height	32.3”	34”

Pressing a switch automatically lowers or raises the EV9’s optional second and third row seats, to make changing between cargo and passengers easier. The Ascent doesn’t offer automatic folding seats.

To make loading groceries and cargo easier when your hands are full, the EV9’s liftgate can be opened and closed just by waiting momentarily behind the back bumper, leaving your hands completely free. The Ascent doesn’t offer a hands-free gesture to open its liftgate, forcing you to put cargo down if your hands are full.

Servicing Ease

The EV9 uses gas struts to support the hood for easier service access. The Ascent 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 EV9 Land/GT-Line’s standard easy entry system raises the steering wheel and 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 Ascent doesn’t offer an easy entry system.

The power windows standard on both the EV9 and the Ascent have locks to prevent small children from operating them. When the lock on the EV9 is engaged the driver can still operate all of the windows, for instance to close one opened by a child. The Ascent prevents the driver from operating the other windows just as it does the other passengers.

The EV9’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 Ascent’s rear power window switches have to be held the entire time to open or close them fully.

On a hot day the EV9’s driver can lower all the windows from a distance using the keyless remote. The driver of the Ascent can only operate the windows from inside the vehicle, with the ignition on.

The EV9’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 Ascent’s standard manually variable intermittent wipers have to be constantly adjusted.

The Kia EV9 has power folding mirrors that offer unparalleled convenience while maneuvering in tight places or parked. With the mirrors folded it’s easier to walk past and help prevent parking damage. The mirrors can be quickly unfolded when the driver is ready to leave. Power folding mirrors are only offered on the Ascent Onyx/Limited/Touring/Bronze.

The EV9 has standard front air conditioned seats and the EV9 Land/GT-Line also has them in the second row. This keeps the passengers comfortable and takes the sting out of hot seats in summer. The Ascent doesn’t offer air-conditioned seats for the second row.

The EV9 GT-Line has standard massaging front seats in order to maximize comfort and eliminate fatigue on long trips. Massaging seats aren’t available in the Ascent.

To quickly and conveniently keep personal devices charged without cables tangling and wearing out, the Kia EV9 has a standard wireless phone charging system (Qi) in the center console. Wireless charging costs extra on the Ascent.

The EV9 (except Light/Wind)’s optional 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 Ascent doesn’t offer an automated parking system.

Model Availability

The EV9 is available in both rear-wheel drive and four-wheel drive configurations. The Ascent doesn’t offer a two-wheel drive configuration.
