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 Tucson Plug-In Hybrid are reminded to check the back seat. The ID.4 doesn’t offer a back seat reminder.
To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the Tucson Plug-In Hybrid. But it costs extra on the ID.4.
When descending a steep, off-road slope, the Tucson Plug-In Hybrid AWD’s standard Downhill Brake Control allows you to creep down safely. The ID.4 doesn’t offer Downhill Brake Control.
Both the Tucson Plug-In Hybrid and the ID.4 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, blind spot warning systems, rearview cameras, rear cross-path warning, driver alert monitors and available around view monitors.
