Both the EV6 and Nexo have child safety locks to prevent children from opening the rear doors. The EV6 has power child safety locks, allowing the driver to activate and deactivate them from the driver's seat and to know when they're engaged. The Nexo’s child locks have to be individually engaged at each rear door with a manual switch. The driver can’t know the status of the locks without opening the doors and checking them.
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 EV6 are reminded to check the back seat if they opened the rear door before starting out. The Nexo doesn’t offer a back seat reminder.
The Kia EV6 has a standard driver’s side knee airbag mounted low on the dashboard. The knee airbag helps prevent the driver from sliding under the seatbelts or the main frontal airbag; this keeps the driver better positioned during a collision for maximum protection. A knee airbag also helps keep the legs from striking the dashboard, preventing knee and leg injuries in the case of a serious frontal collision. The Nexo doesn’t offer knee airbags.
Over 200 people are killed each year when backed over by motor vehicles. The EV6 offers optional Parking Collision-Avoidance Reverse that uses rear sensors to monitor for objects to the rear and automatically applies the brakes to prevent a collision. The Nexo doesn’t offer automatic braking for stationary objects directly to the rear.
The EV6 offers all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The Nexo doesn’t offer all-wheel drive.
Both the EV6 and the Nexo 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.
