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 Buick Enclave doesn’t offer pretensioners for its second-row seat belts.
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 Enclave doesn’t offer pre-crash pretensioners.
Both the Range Rover Sport and Enclave 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 Enclave’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.
To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the Range Rover Sport. But it costs extra on the Enclave.
Both the Range Rover Sport and Enclave 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 Enclave’s Rear Cross Traffic Alert doesn’t automatically brake.
The Range Rover Sport’s driver alert monitor detects an inattentive driver then sounds a warning and suggests a break. According to the NHTSA, drivers who fall asleep cause about 100,000 crashes and 1500 deaths a year. The Enclave doesn’t offer a driver alert monitor.
Both the Range Rover Sport and the Enclave have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, 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 and rear cross-path warning.
