For enhanced safety, the front seat shoulder belts of the GMC Yukon XL are height-adjustable to accommodate a wide variety of driver and passenger heights. A better fit can prevent injuries and the increased comfort also encourages passengers to buckle up. The BMW X7 doesn’t offer height-adjustable front seat belts.
In the past twenty years hundreds of infants and young children have died after being left in vehicles, usually by accident. When turning the vehicle off, drivers of the Yukon XL are reminded to check the back seat if they opened the rear door before starting out. The X7 doesn’t offer a back seat reminder.
The Yukon XL (except SLE with front bench seat) has a standard front seat center airbag, which deploys between the driver and front passenger, protecting them from injuries caused by striking each other in serious side impacts. The X7 doesn’t offer front seat center airbags.
Over 200 people are killed each year when backed over by motor vehicles. The Yukon XL Denali offers optional Reverse Automatic Braking that uses rear sensors to monitor and automatically apply the brakes to prevent a rear collision. The X7 doesn’t offer backup collision prevention brakes.
Both the Yukon XL and the X7 have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, 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 all wheel drive, blind spot warning systems, around view monitors and rear cross-path warning.
