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 Cadillac XT5 doesn’t offer pretensioners for the middle seat belts.
Both the Range Rover Sport and XT5 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 XT5’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 XT5.
When descending a steep, off-road slope, the Range Rover Sport’s standard Hill Descent Control allow you to creep down safely. The XT5 doesn’t offer Hill Descent Control.
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 XT5 doesn’t offer a driver alert monitor.
Both the Range Rover Sport and the XT5 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.
The Land Rover Range Rover Sport weighs 532 to 1515 pounds more than the Cadillac XT5. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.
