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 9’s headlights were rated “Good” by the IIHS, while the EX90’s headlights are rated “Acceptable.”
The Ioniq 9’s power mirror controls are mounted on the armrest for easy access. The EX90’s power mirror controls are embedded in the infotainment system, seriously distracting drivers who have to adjust them while driving.
The Ioniq 9 SEL/Limited/Calligraphy has standard front air conditioned seats and the Ioniq 9 Limited/Calligraphy also has them in the second row. This keeps the passengers comfortable and takes the sting out of hot seats in summer. The EX90 doesn’t offer air-conditioned seats for the second row.
The Ioniq 9 offers an optional 115-volt a/c outlet in the cargo area, allowing you to recharge a laptop or run small household appliances without special adapters that can break or get misplaced. The EX90 doesn’t offer a house-current electrical outlet.
The Ioniq 9 Calligraphy’s Parking Assist can parallel park 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 EX90’s automatic parking system does not offer parking by remote control.
