For enhanced safety, the front and middle 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 GMC Yukon XL doesn’t offer pretensioners for the middle seat belts.
The Range Rover Sport’s optional pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Yukon XL doesn’t offer pre-crash pretensioners.
Both the Range Rover Sport and Yukon XL 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 Yukon XL’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 Yukon XL.
The Range Rover Sport’s optional 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 Yukon XL doesn’t offer a driver alert monitor.

The Yukon XL uses a body-on-frame design, which has no frame members above the floor of the vehicle.
Both the Range Rover Sport and the Yukon XL have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, height adjustable front shoulder belts, plastic fuel tanks, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems, rearview cameras, available blind spot warning systems, around view monitors and rear cross-path warning.
