In the past twenty years hundreds of infants and young children have died after being left in vehicles, usually by accident. When turning the vehicle off, drivers of the Ioniq 5 are reminded to check the back seat if they opened the rear door before starting out. The Polestar 2 doesn’t offer a back seat reminder.
When descending a steep, off-road slope, the Ioniq 5’s standard Downhill Brake Control allows you to creep down safely. The Polestar 2 doesn’t offer Downhill Brake Control.
To help make backing out of a parking space safer, the Ioniq 5 has a standard rear cross-path warning system, which uses sensors in the rear bumper to alert the driver to vehicles approaching from the side, helping the driver avoid collisions. Rear cross-path warning costs extra on the Polestar 2.
Both the Ioniq 5 and the Polestar 2 have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front 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, rearview cameras, driver alert monitors and available around view monitors.
