The Hyundai Ioniq 5 has achieved the Insurance Institute for Highway Safety’s (IIHS) highest rating of “Top Safety Pick Plus” for the 2026 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, a “Good” score in the revised pedestrian crash prevention test, and an “Acceptable” score in the revised vehicle-to-vehicle crash prevention test. The Ariya is not even a standard “Top Safety Pick” for 2026.

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 Ariya’s 3-year/36,000-mile basic warranty expires 2 years or 24,000 miles sooner.

The Ioniq 5 Limited AWD handles at .88 G’s, while the Ariya Platinum+ pulls only .84 G’s of cornering force in a Motor Trend skidpad test.

The Ioniq 5 AWD executes Motor Trend’s “Figure Eight” maneuver quicker than the Ariya Platinum+ (25.6 seconds vs. 26.3 seconds).

For greater off-road capability the Ioniq 5 XRT has a greater minimum ground clearance than the Ariya (7 vs. 6.7 inches), allowing the Ioniq 5 to travel over rougher terrain without being stopped or damaged.

The design of the Hyundai Ioniq 5 amounts to more than styling. The Ioniq 5 has an aerodynamic coefficient of drag of .282 Cd. That is lower than the Ariya (.3 to .33) and many sports cars. A more efficient exterior helps keep the interior quieter and helps the Ioniq 5 get better fuel mileage.

The front grille of the Ioniq 5 uses electronically controlled shutters to close off airflow and reduce drag when less engine cooling is needed. This helps improve highway fuel economy. The Ariya doesn’t offer active grille shutters.

The Ioniq 5 has 5.3 cubic feet more passenger volume than the Ariya (106.5 vs. 101.2).

The Ioniq 5 has .2 inches more front headroom, .6 inches more front shoulder room, .4 inches more rear headroom, 2.4 inches more rear legroom, 1.1 inches more rear hip room and 1.8 inches more rear shoulder room than the Ariya.

Maximum trailer towing in the Nissan Ariya is limited to 1500 pounds. The Ioniq 5 offers up to a 2700 lbs. towing capacity.

The Ioniq 5 uses gas struts to support the hood for easier service access. The Ariya 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.

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 Ariya doesn’t offer a remote starting system.

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 Ariya’s headlights are rated “Acceptable.”

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

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 Ariya doesn’t offer a house-current electrical outlet.

The Ioniq 5 XRT/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 Ariya Platinum+’s automatic parking system does not offer parking by remote control.

The Hyundai Ioniq 5 outsold the Nissan Ariya by over three to one during 2025.
