The Range Rover Sport’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The R1S doesn’t offer pre-crash pretensioners.
Both the Range Rover Sport and R1S 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 R1S’ 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 R1S have rear cross-traffic warning, but the Range Rover Sport has Rear Traffic Braking (automatically applies the brakes) to better prevent a collision when backing near traffic. The R1S’ Rear Cross-Traffic Warning doesn’t automatically brake.
Both the Range Rover Sport and the R1S have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front and rear seatbelt pretensioners, 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, around view monitors, rear cross-path warning and driver alert monitors.
