The Ioniq 5’s liftgate lifts up in one piece, completely out of the way of loading and unloading, while sheltering the cargo loading area. The R1S’ tailgate’s top part raises up, but the bottom part lowers, getting in the way of loading and making an uneven surface for sliding cargo.

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 R1S doesn’t offer a hands-free gesture to open its tailgate, forcing you to put cargo down if your hands are full.

The Ioniq 5’s standard side window demisters help clear frost or condensation from the side windows in the winter. The R1S doesn’t even offer side window demisters, so the driver may have to wipe the windows from the outside to gain side vision.

Manual rear side window sunshades are available in the Ioniq 5 to help block heat and glare for the rear passengers. The R1S 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.

The Ioniq 5 Limited’s Parking Assist can parallel park or back into a parking spot by itself, starting, stopping and changing direction automatically.
