Both the Ioniq 5 and Prius have child safety locks to prevent children from opening the rear doors. The Ioniq 5 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 Prius’ 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.

When descending a steep, off-road slope, the Ioniq 5’s standard Downhill Brake Control allows you to creep down safely. The Prius doesn’t offer Downhill Brake Control.

To help make backing out of a parking space safer, the Ioniq 5 has standard Rear Cross-Traffic Collision Warning with Rear Cross-Traffic Collision-Avoidance Assist, systems which detect vehicles approaching from the sides and can automatically apply the brakes to prevent a collision. Parking Support Brake costs extra on the Prius.

Both the Ioniq 5 and the Prius have standard driver and passenger frontal airbags, front and rear 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 Hyundai Ioniq 5 weighs 804 to 1764 pounds more than the Toyota Prius. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.

The Ioniq 5 can travel with zero emissions for 221 to 318 miles (dependent on model). The Prius can’t move without running its internal combustion engine.

Environmental Friendliness

In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the Hyundai Ioniq 5 higher (10 out of 10) than the Toyota Prius (7). This means the Ioniq 5 produces up to 11.8 pounds less smog-producing pollutants than the Prius every 15,000 miles.

Transmission

The Ioniq 5 N’s launch control uses engine electronics to hold engine RPM’s precisely in order to provide the most stable and rapid acceleration possible, using all of the available traction. The Prius doesn’t offer launch control.

Brakes and Stopping

For better stopping power the Ioniq 5’s brake rotors are larger than those on the Prius:

	Ioniq 5	Ioniq 5 N	Prius	Prius AWD-e
Front Rotors	12.8 inches	15.7 inches	11.1 inches	12 inches
Rear Rotors	12.8 inches	14.2 inches	11 inches	11 inches

The Ioniq 5 N’s standard front and rear disc brakes are vented to help dissipate heat for shorter stops with less fading. The rear discs on the Prius are solid, not vented.

The Ioniq 5 stops much shorter than the Prius:

	Ioniq 5	Prius
70 to 0 MPH	153 feet	174 feet	Car and Driver
60 to 0 MPH	102 feet	132 feet	Motor Trend
60 to 0 MPH (Wet)	144 feet	148 feet	Consumer Reports

Tires and Wheels

For better traction, the Ioniq 5 has larger standard tires than the Prius (235/55R19 vs. 195/60R17). The Ioniq 5 N’s tires are larger than the largest tires available on the Prius (275/35R21 vs. 195/60R17).

The Ioniq 5 N’s tires provide better handling because they have a lower 35 series profile (height to width ratio) that provides a stiffer sidewall than the Prius XLE/Limited’s 50 series tires.

For better ride, handling and brake cooling the Ioniq 5 XRT has standard 18-inch wheels. Smaller 17-inch wheels are standard on the Prius LE. The Ioniq 5 N’s 21-inch wheels are larger than the 19-inch wheels on the Prius XLE/Limited.

The Ioniq 5 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 Prius doesn’t offer vehicle monitored tire inflation.

Suspension and Handling

The Ioniq 5 offers an available driver-adjustable suspension system. It allows the driver to choose between an extra-supple ride, reducing fatigue on long trips, or a sport setting, which allows maximum control for tricky roads or off-road. The Prius’ suspension doesn’t offer adjustable shock absorbers.

For a smoother ride and more stable handling, the Ioniq 5’s wheelbase is 9.8 inches longer than on the Prius (118.1 inches vs. 108.3 inches).

For better handling and stability, the average track (width between the wheels) on the Ioniq 5 is 3.2 inches wider in the front and 2.8 inches wider in the rear than the track on the Prius.

The Ioniq 5’s front to rear weight distribution is more even (50% to 50%) than the Prius’ (59.6% to 40.4%). This gives the Ioniq 5 more stable handling and braking.

The Ioniq 5 N handles at .96 G’s, while the Prius Limited pulls only .82 G’s of cornering force in a Motor Trend skidpad test.

Passenger Space

The Ioniq 5 has 15.3 cubic feet more passenger volume than the Prius (106.5 vs. 91.2).

The Ioniq 5 has 1.8 inches more front headroom, 2.4 inches more front shoulder room, 2.3 inches more rear headroom, 4.6 inches more rear legroom, 1.9 inches more rear hip room and 4.9 inches more rear shoulder room than the Prius.

For enhanced passenger comfort on long trips the Ioniq 5’s rear seats recline. The Prius’ rear seats don’t recline.

Cargo Capacity

To make loading groceries and cargo easier when your hands are full, the Ioniq 5’s liftgate can be opened just by waiting momentarily behind the back bumper, leaving your hands completely free. The Prius doesn’t offer a hands-free gesture to open its liftgate, forcing you to put cargo down if your hands are full.

Payload and Towing

The Ioniq 5 XRT offers up to a 2700 lbs. towing capacity. The Prius has no towing capacity.

The Ioniq 5 has a higher standard payload capacity than the Prius (957 vs. 860 lbs.).

Servicing Ease

The Ioniq 5 uses gas struts to support the hood for easier service access. The Prius 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 Ioniq 5 Limited has a standard heads-up display that projects speed, navigation instruction and driver assistance information readouts in front of the driver’s line of sight, allowing drivers to view information without diverting their eyes from the road. The Prius doesn’t offer a heads-up display.

The Ioniq 5’s standard Proximity Key allows you to unlock the doors from either front door handle, open the cargo door, and start the vehicle, all without removing the key from the pocket or purse. Pushbutton Start standard on the Prius doesn’t offer a sensor on the trunk or any door except the driver’s, so you’ll have to walk to the driver's door to touch the handle. Pushbutton Start is not available on the Prius XLE/Limited.

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

The Insurance Institute for Highway Safety (IIHS) conducts detailed tests on headlights for their range both straight ahead and in curves and to be certain they don’t exceed acceptable amounts of glare to oncoming drivers. The Ioniq 5’s headlights were rated “Good” to “Acceptable” by the IIHS, while the Prius’ headlights are rated “Acceptable.”

The Ioniq 5 has a standard automatic headlight on/off feature. When the ignition is on, the headlights automatically turn on at dusk and off after dawn. When the ignition turns off, the headlights turn off after a delay timed to allow you to securely get to your front door. The Prius has an automatic headlight on/off feature standard only on the XLE/Limited.

Manual rear side window sunshades are available in the Ioniq 5 to help block heat and glare for the rear passengers. The Prius doesn’t offer rear side window sunshades.

When the Ioniq 5 Limited 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 Prius’ mirrors don’t automatically adjust for backing.

Both the Hyundai Ioniq 5 and Toyota Prius offer exterior mirrors that can be folded to provide convenience. The Ioniq 5 offers available 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 Prius’ foldable mirrors are manual, requiring the driver to get out and physically fold them once parked and unfold them before getting in.

The Ioniq 5’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 Prius doesn’t offer dual zone air conditioning.

Both the Ioniq 5 and the Prius offer rear vents. For greater rear passenger comfort, the Ioniq 5 SEL/Limited/XRT/N has standard rear air conditioning vents to keep rear occupants cool in summer or warm in winter. The Prius doesn’t offer rear air conditioning vents, only heat vents.

The Ioniq 5 Limited has a 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 Prius doesn’t offer a house-current electrical outlet.

The Ioniq 5 Limited’s Parking Assist can parallel park or back into a parking spot by itself, starting, stopping and changing direction automatically. Remote Parking Assist will park and retrieve your car remotely: press a button and watch it park itself. This is ideal for tight locations. The Prius Limited’s automatic parking system does not offer parking by remote control.

Recommendations

The Ioniq 5 was chosen as a Car and Driver’s “Top Ten” for 2025 and 3 more times in the last 4 years. The Prius/Prius Prime hasn’t been picked since 2024, and the Prius/Prius Prime has only been chosen twice.
