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 R1S doesn’t offer a back seat reminder.
Over 200 people are killed each year when backed over by motor vehicles. The Ioniq 5 Limited has standard Parking Collision Avoidance Assist that uses rear sensors to monitor and automatically apply the brakes to prevent a rear collision. The R1S doesn’t offer backup collision prevention brakes.
Both the Ioniq 5 and the R1S have standard driver and passenger frontal airbags, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, lane departure warning systems, blind spot warning systems, rearview cameras, rear cross-path warning, driver alert monitors and available front parking sensors.
