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 Ioniq 5 doesn’t offer knee airbags.

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 Ioniq 5 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 Hyundai Ioniq 5 has not been tested.

Both the ZDX and the Ioniq 5 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, 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 560 to 1908 pounds more than the Hyundai Ioniq 5. 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 Hyundai Ioniq 5:

Ioniq 5 Long Range electric motor	225 HP	258 lbs.-ft.
Ioniq 5 electric motors	320 HP	446 lbs.-ft.

As tested in Car and Driver the ZDX Type S electric motors is faster than the Hyundai Ioniq 5 electric motors:

	ZDX	Ioniq 5
Zero to 60 MPH	4.3 sec	4.5 sec
Zero to 100 MPH	10 sec	12.6 sec
5 to 60 MPH Rolling Start	4.4 sec	4.8 sec
Quarter Mile	12.7 sec	13.2 sec
Speed in 1/4 Mile	112 MPH	102 MPH
Top Speed	131 MPH	117 MPH

Fuel Economy and Range

On the EPA test cycle the ZDX A-Spec AWD gets better mileage than the Ioniq 5 N (94 city/80 hwy vs. 84 city/72 hwy MPGe).

The ZDX can travel longer on a full charge than the Ioniq 5 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
Ioniq 5
	RWD	Standard Range Electric Motor	245 miles
	AWD	19" Wheels Electric Motors	290 miles
		20" Wheels Electric Motors	269 miles
		XRT Electric Motors	259 miles
		N Electric Motors	221 miles

Brakes and Stopping

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 Ioniq 5 are solid, not vented.

The ZDX stops much shorter than the Ioniq 5:

	ZDX	Ioniq 5
70 to 0 MPH	168 feet	185 feet	Car and Driver
60 to 0 MPH	113 feet	123 feet	Motor Trend

Tires and Wheels

For better traction, the ZDX has larger standard tires than the Ioniq 5 (265/50R20 vs. 235/55R19).

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 Ioniq 5 XRT’s standard 60 series tires.

For better ride, handling and brake cooling the ZDX A-Spec has standard 20-inch wheels. Smaller 18-inch wheels are standard on the Ioniq 5 XRT. The ZDX Type S’ 22-inch wheels are larger than the 21-inch wheels on the Ioniq 5 N.

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

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 Ioniq 5 doesn’t offer self-sealing tires.

Suspension and Handling

For a smoother ride and more stable handling, the ZDX’s wheelbase is 3.7 inches longer than on the Ioniq 5 (121.8 inches vs. 118.1 inches).

For better handling and stability, the track (width between the wheels) on the ZDX is 1.5 inches wider in the front and 1.3 inches wider in the rear than the average track on the Ioniq 5.

The ZDX Type S handles at .85 G’s, while the Ioniq 5 SEL AWD pulls only .84 G’s of cornering force in a Car and Driver skidpad test.

The ZDX Type S executes Motor Trend’s “Figure Eight” maneuver quicker than the Ioniq 5 Limited AWD (25.1 seconds @ .75 average G’s vs. 25.7 seconds @ .71 average G’s).

For greater off-road capability the ZDX has a 1.4 inches greater minimum ground clearance than the Ioniq 5 N (7 vs. 5.6 inches), allowing the ZDX to travel over rougher terrain without being stopped or damaged.

Passenger Space

The ZDX has 12.2 inches more front hip room, 1.3 inches more front shoulder room, 12.7 inches more rear hip room and .3 inches more rear shoulder room than the Ioniq 5.

Cargo Capacity

The ZDX has a much larger cargo volume with its rear seat up than the Ioniq 5 with its rear seat up (29.7 vs. 26.3 cubic feet). The ZDX has a much larger cargo volume with its rear seat folded than the Ioniq 5 with its rear seat folded (63 vs. 58.5 cubic feet).

Pressing a switch automatically lowers the ZDX’s rear seats, to make changing between passengers and cargo easier. The Ioniq 5 doesn’t offer automatic folding seats.

Towing

The ZDX’s standard towing capacity is much higher than the Ioniq 5’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 Ioniq 5 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 Hyundai. J.D. Power ranks Acura 6th in service department satisfaction (above the industry average). With a 55% lower rating, Hyundai is ranked 30th.

Ergonomics

Unlike the driver-only memory seat and mirrors in the Ioniq 5 Limited, 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 Ioniq 5’s standard passenger windows don’t 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. Proximity Key standard on the Ioniq 5 doesn’t offer a sensor on the rear doors, so you’ll have to reach a front handle to unlock the rear door.

The ZDX’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 Ioniq 5’s standard manually variable intermittent wipers have to be constantly adjusted.

The Acura ZDX 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 Ioniq 5 SEL/XRT/Limited/N.

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 is only available on the Ioniq 5 SEL/Limited/XRT/N.

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. Hyundai charges extra for Homelink® on the Ioniq 5.

To quickly and conveniently keep personal devices charged without cables tangling and wearing out, the Acura ZDX has a standard wireless phone charging system (Qi) in the center console. Only the Ioniq 5 SEL/Limited/XRT/N offers wireless charging.
