The Prius (except L/LE) offers an available heads-up display that projects speed and other key instrumentation readouts in front of the driver’s line of sight, allowing drivers to view information without diverting their eyes from the road. The Ioniq Hybrid doesn’t offer a heads-up display.

The Prius’ front and rear power windows all open or close fully with one touch of the switches, making it more convenient at drive-up windows and toll booths, or when talking with someone outside the car. The Ioniq Hybrid’s standard passenger windows don’t open or close automatically. With the Ioniq Hybrid Limited’s power windows, only the front windows open or close automatically.

If the windows are left open on the Prius the driver can close them all at the outside door handle. On a hot day the driver can lower the windows at the outside door handle or from a distance using the keyless remote. (This window function must be activated by your Toyota service department.) The driver of the Ioniq Hybrid can only operate the windows from inside the vehicle, with the ignition on.

The Prius XLE/Limited’s standard wipers adjust their speed and turn on and off automatically according to the amount of rainfall on the windshield. The Ioniq Hybrid’s manually variable intermittent wipers have to be constantly adjusted.

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

While driving with high beams on, sensitive light sensors standard on the Prius detect other vehicles which could be blinded and automatically switch to low beams. The Ioniq Hybrid doesn’t offer automatic dimming high beams.

The Prius’ standard outside mirrors include heating elements to clear off the mirrors for better visibility. Hyundai only offers heated mirrors on the Ioniq Hybrid SEL/Limited.

On extremely cold winter days, the Prius XLE/Limited’s standard heated steering wheel provides comfort, allowing the driver to steer safely and comfortably before the car heater warms up. The Ioniq Hybrid doesn’t offer a heated steering wheel.

The Prius LE/XLE/Limited’s Intelligent Parking Assist can parallel park or back into a parking spot by itself, with the driver only controlling speed with the brake pedal. The Ioniq Hybrid doesn’t offer an automated parking system.
