The ID.4’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Ioniq 5 doesn’t offer pre-crash pretensioners.

The ID.4 has a standard Automatic Post-Collision Braking System, which automatically applies the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The Ioniq 5 doesn’t offer a post collision braking system: in the event of a collision that triggers the airbags, more collisions are possible without the protection of airbags that may have already deployed.

Both the ID.4 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, driver alert monitors 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 Volkswagen ID.4 is safer than the Hyundai Ioniq 5:

	ID.4	Ioniq 5
OVERALL STARS	5 Stars	4 Stars
	Driver
STARS	5 Stars	4 Stars

New test not comparable to pre-2011 test results. More stars = Better. Lower test results = Better.

The National Highway Traffic Safety Administration does side impact tests on new vehicles. In this test, which crashes the vehicle into a flat barrier at 38.5 MPH and into a post at 20 MPH, results indicate that the Volkswagen ID.4 is safer than the Hyundai Ioniq 5:

	ID.4	Ioniq 5
	Front Seat
STARS	5 Stars	5 Stars
Abdominal Force	128 lbs.	131 lbs.
	Rear Seat
STARS	5 Stars	5 Stars
HIC	125	267
Spine Acceleration	35 G’s	60 G’s
Hip Force	527 lbs.	741 lbs.
	Into Pole
STARS	5 Stars	5 Stars
Max Damage Depth	6 inches	7 inches

New test not comparable to pre-2011 test results. More stars = Better. Lower test results = Better.

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 Volkswagen ID.4 is safer than the Ioniq 5:

	ID.4	Ioniq 5

			MPGe
ID.4
	RWD	Pro Electric Motor	122 city/104 hwy
	AWD	Pro Electric Motors	108 city/96 hwy
Ioniq 5

	AWD	Pro Electric Motors	263 miles
Ioniq 5
	RWD	Standard Range Electric Motor	220 miles
	AWD	Electric Motors	260 miles

Brakes and Stopping

For better stopping power the ID.4’s front brake rotors are larger than those on the Ioniq 5:

	ID.4	Ioniq 5
Front Rotors	14.1 inches	12.8 inches

The ID.4 stops much shorter than the Ioniq 5:

	ID.4	Ioniq 5
70 to 0 MPH	169 feet	185 feet	Car and Driver
60 to 0 MPH (Wet)	138 feet	144 feet	Consumer Reports

Tires and Wheels

The ID.4 Pro S Plus’ 255/40R21 rear tires provide better handling because they have a lower 40 series profile (height to width ratio) that provides a stiffer sidewall than the Ioniq 5 Limited AWD’s 45 series tires.

For better ride, handling and brake cooling the ID.4 Pro S Plus has standard 21-inch wheels. The Ioniq 5’s largest wheels are only 20-inches.

Suspension and Handling

The ID.4 Pro S AWD handles at .86 G’s, while the Ioniq 5 SEL AWD pulls only .84 G’s of cornering force in a Car and Driver skidpad test.

For better maneuverability, the ID.4’s turning circle is 7.8 feet tighter than the Ioniq 5’s (31.5 feet vs. 39.3 feet). The ID.4 AWD’s turning circle is 2.9 feet tighter than the Ioniq 5’s (36.42 feet vs. 39.3 feet).

For greater off-road capability the ID.4 has a greater minimum ground clearance than the Ioniq 5 (6.8 vs. 6.1 inches), allowing the ID.4 to travel over rougher terrain without being stopped or damaged.

Passenger Space

The ID.4 has .8 inches more front headroom and .5 inches more front hip room than the Ioniq 5.

Cargo Capacity

The ID.4 has a much larger cargo volume with its rear seat up than the Ioniq 5 with its rear seat up (30.3 vs. 27.2 cubic feet). The ID.4 has a much larger cargo volume with its rear seat folded than the Ioniq 5 with its rear seat folded (64.2 vs. 59.3 cubic feet).

Towing

The ID.4’s minimum standard towing capacity is much higher than the Ioniq 5’s (2200 vs. 0 pounds).

Standard trailer stability control on the ID.4 uses the Electronic Stability Control 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.

Ergonomics

The ID.4’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. With the Ioniq 5 SEL/Limited’s power windows, only the front windows open or close automatically.

If the windows are left open on the ID.4 the driver can close them all at the outside door handle or from a distance using the remote. On a hot day the driver can lower the windows from a distance using the keyless remote. The driver of the Ioniq 5 can only close the windows from inside the vehicle, with the ignition on.

The ID.4’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.

Heated windshield washer nozzles are standard on the ID.4 to prevent washer fluid and nozzles from freezing and help continue to keep the windshield clear in sub-freezing temperatures. The Ioniq 5 doesn’t offer heated windshield washer nozzles.

To improve rear visibility by keeping the rear window clear, the ID.4 has a standard rear wiper. The Ioniq 5 doesn’t offer a rear wiper.

Consumer Reports rated the ID.4’s headlight performance “Good,” a higher rating than the Ioniq 5’s headlights, which were rated “Fair.”

To help drivers avoid possible obstacles, the ID.4 S/S Plus has standard cornering lights to illuminate around corners when the turn signals are activated. The Ioniq 5 doesn’t offer cornering lights. The ID.4 S/S Plus also has standard adaptive headlights to illuminate around corners automatically by reading vehicle speed and steering wheel angle.

Both the ID.4 and the Ioniq 5 have standard heated front seats. The ID.4 Pro S Plus also has standard heated rear seats to keep those passengers extremely comfortable in the winter. Heated rear seats aren’t available in the Ioniq 5.

The ID.4 S/S Plus has standard massaging front seats in order to maximize comfort and eliminate fatigue on long trips. Massaging seats aren’t available in the Ioniq 5.

To quickly and conveniently keep personal devices charged without cables tangling and wearing out, the Volkswagen ID.4 has a standard wireless phone charging system (Qi) in the center console. Only the Ioniq 5 SEL/Limited offers wireless charging.

Economic Advantages

Insurance will cost less for the ID.4 owner. The Complete Car Cost Guide estimates that insurance for the ID.4 will cost $910 less than the Ioniq 5 over a five-year period.

IntelliChoice estimates that five-year ownership costs (depreciation, financing, insurance, fuel, fees, repairs and maintenance) for the Volkswagen ID.4 will be $1847 to $2138 less than for the Hyundai Ioniq 5.

Recommendations

The Volkswagen ID.4 outsold the Hyundai Ioniq 5 by 11% during 2023.
