Both the Ioniq 5 and Prius Plug-In Hybrid 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 Plug-In Hybrid’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 Ioniq 5 offers all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The Prius Plug-In Hybrid doesn’t offer all-wheel drive.

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 Plug-In Hybrid.

Both the Ioniq 5 and the Prius Plug-In Hybrid 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 573 to 1400 pounds more than the Toyota Prius Plug-In Hybrid. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.

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 Hyundai Ioniq 5 is safer than the Toyota Prius Plug-In Hybrid:

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

The Hyundai Ioniq 5 has achieved the Insurance Institute for Highway Safety’s (IIHS) highest rating of “Top Safety Pick Plus” for the 2024 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 an “Acceptable” score in the revised pedestrian crash prevention test. The Prius Plug-In Hybrid is only a standard “Top Safety Pick” for 2024, though it hasn’t yet been rated in the updated moderate overlap frontal test, a requirement for the “Top Safety Pick Plus” award.

Warranty

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

Hyundai’s powertrain warranty covers the Ioniq 5 5 years and 40,000 miles longer than Toyota covers the Prius Plug-In Hybrid. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 10 years or 100,000 miles. Coverage on the Prius Plug-In Hybrid ends after only 5 years or 60,000 miles.

The Ioniq 5’s corrosion warranty is 2 years longer than the Prius Plug-In Hybrid’s (7 vs. 5 years).

Hyundai pays for scheduled maintenance on the Ioniq 5 for 1 year and 11000 miles longer than Toyota pays for maintenance for the Prius Plug-In Hybrid (3/36,000 vs. 2/25000).

Tires and Wheels

For better traction, the Ioniq 5 has larger standard tires than the Prius Plug-In Hybrid (235/55R19 vs. 195/60R17). The Ioniq 5 N’s tires are larger than the largest tires available on the Prius Plug-In Hybrid (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 Plug-In Hybrid XSE’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 Plug-In Hybrid SE. The Ioniq 5 N’s 21-inch wheels are larger than the 19-inch wheels on the Prius Plug-In Hybrid XSE.

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 Plug-In Hybrid 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 Plug-In Hybrid’s 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 Plug-In Hybrid (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 Plug-In Hybrid.

The Ioniq 5’s front to rear weight distribution is more even (50% to 50%) than the Prius Plug-In Hybrid’s (56% to 44%). This gives the Ioniq 5 more stable handling and braking.

The Ioniq 5 N handles at .96 G’s, while the Prius Plug-In Hybrid SE pulls only .79 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 Plug-In Hybrid (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, 3.5 inches more rear legroom, 1.9 inches more rear hip room and 4.9 inches more rear shoulder room than the Prius Plug-In Hybrid.

For enhanced passenger comfort on long trips the Ioniq 5’s rear seats recline. The Prius Plug-In Hybrid’s 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 Plug-In Hybrid doesn’t offer a hands-free gesture to open its liftgate, forcing you to put cargo down if your hands are full.

Towing

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

Servicing Ease

The Ioniq 5 uses gas struts to support the hood for easier service access. The Prius Plug-In Hybrid 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 has a standard remote vehicle starting system, so the vehicle can be started from inside the driver's house. This allows the driver to comfortably warm up the engine before going out to the vehicle. The climate system will also automatically heat or cool the interior. The Prius Plug-In Hybrid doesn’t offer a remote starting system.

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 Plug-In Hybrid 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 Plug-In Hybrid 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.

To improve rear visibility by keeping the rear window clear, the Ioniq 5 has a standard rear wiper. The Prius Plug-In Hybrid 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 Plug-In Hybrid’s 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 Plug-In Hybrid has an automatic headlight on/off feature standard only on the XSE.

Manual rear side window sunshades are available in the Ioniq 5 to help block heat and glare for the rear passengers. The Prius Plug-In Hybrid 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 Plug-In Hybrid’s mirrors don’t automatically adjust for backing.

Both the Hyundai Ioniq 5 and Toyota Prius Plug-In Hybrid 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 Plug-In Hybrid’s 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 Plug-In Hybrid doesn’t offer dual zone air conditioning.

Both the Ioniq 5 and the Prius Plug-In Hybrid 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 Plug-In Hybrid doesn’t offer rear air conditioning vents, only heat vents.

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 Plug-In Hybrid XSE Premium’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.
