For enhanced safety, the front and rear seat shoulder belts of the Acura ZDX have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision and force limiters to limit the pressure the belts will exert on the passengers. The Kia EV6 doesn’t offer pretensioners for its rear seat belts.

The Acura ZDX has standard driver and front passenger side knee airbags mounted low on the dashboard. These airbags help 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 EV6 doesn’t offer a front passenger side knee airbag.

The ZDX’s standard pretensioning seatbelts also sense rear collisions and remove slack from the seatbelts to help protect the occupants from whiplash and other injuries. The EV6 doesn’t offer a whiplash protection system.

In a Vehicle-to-Vehicle Frontal Crash Prevention 2.0 test conducted by the Insurance Institute for Highway Safety (IIHS), the Acura ZDX 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 Kia EV6 has not been tested.

Both the ZDX and the EV6 have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, 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 Acura ZDX weighs 538 to 1920 pounds more than the Kia EV6. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.

The National Highway Traffic Safety Administration does 35 MPH front crash tests on new vehicles. In this test, results indicate that the Acura ZDX is safer than the Kia EV6:

	Horsepower	Torque
ZDX A-Spec electric motor	358 HP	324 lbs.-ft.
ZDX A-Spec AWD electric motors	490 HP	437 lbs.-ft.
ZDX Type S electric motors	499 HP	544 lbs.-ft.
EV6 Light Short 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.

As tested in Car and Driver the ZDX Type S electric motors is faster than the EV6 Long Range electric motors:

	ZDX	EV6

Quarter Mile	12.7 sec	13.1 sec
Speed in 1/4 Mile	112 MPH	103 MPH
Top Speed	131 MPH	118 MPH

Fuel Economy and Range

The ZDX can travel longer on a full charge than the EV6 on a full charge:

			Miles
ZDX
	RWD	A-Spec Electric Motor	313 miles
	AWD	A-Spec Electric Motors	304 miles
		Type S Electric Motors	278 miles
EV6
	RWD	Light Short Range Electric Motor	240 miles
	AWD	19" Wheels Electric Motors	295 miles
		20" Wheels Electric Motors	270 miles
		GT Electric Motors	231 miles

Brakes and Stopping

For better stopping power the ZDX Type S’ brake rotors are larger than those on the EV6:

	ZDX Type S	EV6	EV6 GT
Front Rotors	15.3 inches	12.8 inches	15 inches

The ZDX’s standard front and rear disc brakes are vented to help dissipate heat for shorter stops with less fading. The rear discs standard on the EV6 are solid, not vented.

The ZDX stops much shorter than the EV6:

	ZDX	EV6
70 to 0 MPH	168 feet	181 feet	Car and Driver
60 to 0 MPH	113 feet	114 feet	Motor Trend

Tires and Wheels

For better traction, the ZDX has larger standard tires than the EV6 (265/50R20 vs. 235/55R19). The ZDX Type S’ tires are larger than the largest tires available on the EV6 (275/40R22 vs. 255/45R20).

The ZDX A-Spec’s standard tires provide better handling because they have a lower 50 series profile (height to width ratio) that provides a stiffer sidewall than the EV6’s standard 55 series tires.

For better ride, handling and brake cooling the ZDX A-Spec has standard 20-inch wheels. Smaller 19-inch wheels are standard on the EV6. The ZDX Type S’ 22-inch wheels are larger than the 21-inch wheels on the EV6 GT.

The Acura ZDX’s wheels have 6 lugs for longer wheel bearing life, less chance of rotor warping and greater strength. The Kia EV6 only has 5 wheel lugs per wheel.

The ZDX has a standard easy tire fill system. When inflating the tires, the vehicle’s integrated tire pressure sensors keep track of the pressure as the tires fill and tell the driver when the tires are inflated to the proper pressure. The EV6 doesn’t offer vehicle monitored tire inflation.

Having a flat tire is dangerous, inconvenient and expensive. The self-sealing tires standard on the ZDX can automatically seal most punctures up to 3/16 of an inch, effectively preventing most flat tires. The EV6 doesn’t offer self-sealing tires.

Suspension and Handling

For a smoother ride and more stable handling, the ZDX’s wheelbase is 7.6 inches longer than on the EV6 (121.8 inches vs. 114.2 inches).

For better handling and stability, the track (width between the wheels) on the ZDX is 2.1 inches wider in the front and 1.8 inches wider in the rear than the average track on the EV6.

For greater off-road capability the ZDX has a greater minimum ground clearance than the EV6 (7 vs. 6.1 inches), allowing the ZDX to travel over rougher terrain without being stopped or damaged.

Passenger Space

The ZDX has 11.2 inches more front hip room, 1.2 inches more front shoulder room, .4 inches more rear legroom, 13.1 inches more rear hip room and 2.4 inches more rear shoulder room than the EV6.

Cargo Capacity

The ZDX has a much larger cargo volume with its rear seat up than the EV6 with its rear seat up (29.7 vs. 24.4 cubic feet). The ZDX has a much larger cargo volume with its rear seat folded than the EV6 with its rear seat folded (63 vs. 46.7 cubic feet).

Towing

The ZDX’s standard towing capacity is much higher than the EV6’s (3500 vs. 0 pounds).

Standard Trailer Sway Control on the ZDX uses the Vehicle Stability Assist sensors to detect trailer sway, then uses individual brakes to counteract any swaying and help keep the tow vehicle and trailer steady. The EV6 doesn’t offer electronic trailer sway control.

Servicing Ease

J.D. Power and Associates surveys of service recipients show that Acura service is better than Kia. J.D. Power ranks Acura 6th in service department satisfaction (above the industry average). With a 45% lower rating, Kia is ranked 27th.

Ergonomics

Unlike the driver-only memory system in the EV6 Wind/GT-Line/GT, the ZDX Type S has a passenger memory, so that when drivers switch, the memory setting adjusts the driver’s seat and the front passenger seat also adjusts to the new passenger’s preset preferences.

The ZDX’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 EV6’s standard passenger windows don’t open or close automatically. With the EV6 GT-Line/GT’s power windows, only the front windows open or close automatically.

The ZDX’s standard Keyless Access System allows you to unlock the doors from any outside door handle, open the cargo door, and start the vehicle, all without removing the key from the pocket or purse. Smart Key standard on the EV6 doesn’t offer a sensor on the rear doors, so you’ll have to reach a front handle to unlock the rear door.

To improve rear visibility by keeping the rear window clear, the ZDX has a standard rear wiper. The EV6 doesn’t offer a rear wiper.

Manual rear side window sunshades are available in the ZDX to help block heat and glare for the rear passengers. The EV6 doesn’t offer rear side window sunshades.

The ZDX has a standard heated steering wheel to take the chill out of steering on extremely cold winter days before the vehicle heater warms up. A heated steering wheel costs extra on the EV6.

The Acura ZDX has a standard Homelink wireless remote control system for garage door operation and device management, conveniently located on the infotainment. Homelink® eliminates the need for separate garage door openers and associated risks of losing, breaking, or having dead batteries. Kia charges extra for Homelink® on the EV6.
