Both the Range Rover Sport and AMG GLC have child safety locks to prevent children from opening the rear doors. The Range Rover Sport 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 AMG GLC’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.
When descending a steep, off-road slope, the Range Rover Sport’s standard Hill Descent Control allow you to creep down safely. The AMG GLC doesn’t offer Hill Descent Control.
The Range Rover Sport’s standard lane departure warning system alerts a temporarily inattentive driver when the vehicle begins to leave its lane and gently nudges the vehicle back towards its lane. A lane departure warning system costs extra on the AMG GLC.
Both the Range Rover Sport and the AMG GLC have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front and rear seatbelt pretensioners, height adjustable front shoulder belts, four-wheel antilock brakes, all wheel drive, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, rearview cameras, available blind spot warning systems, around view monitors, rear cross-path warning and driver alert monitors.
