For enhanced safety, the front and rear seat shoulder belts of the Land Rover Range Rover Sport have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision and force limiters to limit the pressure the belts will exert on the passengers. The BMW X5 xDrive45e doesn’t offer pretensioners for its second-row seat belts.
Both the Range Rover Sport and X5 xDrive45e 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 X5 xDrive45e’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.
Both the Range Rover Sport and the X5 xDrive45e have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, four-wheel antilock brakes, all wheel drive, 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 and driver alert monitors.
