The X7’s 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.
For enhanced safety, the middle seat shoulder belts of the BMW X7 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 GMC Yukon XL doesn’t offer height-adjustable middle seat belts.
The X7 has standard Post-Crash Braking, which automatically apply the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The Yukon XL doesn’t offer a post collision braking system: in the event of a collision that triggers the airbags, more collisions are possible without the protection of airbags that may have already deployed.
To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the X7. But it costs extra on the Yukon XL.
The X7’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 Yukon XL doesn’t offer a driver alert monitor.
For better protection of the passenger compartment, the X7 uses safety cell construction with a three-dimensional high-strength frame that surrounds the passenger compartment. It provides extra impact protection and a sturdy mounting location for door hardware and side impact beams. The Yukon XL uses a body-on-frame design, which has no frame members above the floor of the vehicle.
Both the X7 and the Yukon XL 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, rearview cameras and available around view monitors.
The X7 comes with a full 4-year/50,000-mile basic warranty, which covers the entire truck and includes 24-hour roadside assistance. The Yukon XL’s 3-year/36,000-mile basic warranty expires 1 year and 14,000 miles sooner.
The X7’s corrosion warranty is 6 years and unlimited miles longer than the Yukon XL’s (12/unlimited vs. 6/100,000).
BMW pays for scheduled maintenance on the X7 for 3 years and 36,000 miles. BMW will pay for oil changes, lubrication and any other required maintenance. GMC only pays for the first scheduled maintenance visit on the Yukon XL.
For smoother operation, better efficiency and fewer moving parts, the engines in the X7 have an overhead cam design, rather than the old pushrod design of the engines in the Yukon XL.
J.D. Power and Associates’ 2019 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that BMW vehicles are more reliable than GMC vehicles. J.D. Power ranks BMW 7th in reliability, above the industry average. With 39 more problems per 100 vehicles, GMC is ranked 22nd.
From surveys of all its subscribers, Consumer Reports’ December 2019 Auto Issue reports that BMW vehicles are more reliable than GMC vehicles. Consumer Reports ranks BMW 5 places higher in reliability than GMC.
The X7 has more powerful engines than the Yukon XL:
X7 xDrive50i 4.4 turbo V8
X7 M50i 4.4 turbo V8
Yukon XL 5.3 V8
Yukon XL Denali 6.2 V8
Regenerative brakes improve the X7’s fuel efficiency by converting inertia back into energy instead of wasting it. The Yukon XL doesn’t offer a regenerative braking system.
The X7’s launch control uses engine electronics to hold engine RPM’s precisely in order to provide the most stable and rapid acceleration possible, using all of the available traction. The Yukon XL doesn’t offer launch control.
For better traction, the X7 has larger standard tires than the Yukon XL (F:275/40R22 & R:315/35R22 vs. 265/65R18). The X7’s tires are larger than the largest tires available on the Yukon XL (285/45R21 vs. 275/65R20).
The X7’s standard tires provide better handling because they have a lower 45 series profile (height to width ratio) that provides a stiffer sidewall than the Yukon XL’s standard 65 series tires. The X7’s optional 275/40R22 front and 315/35R22 rear tires have a lower 40 series front and 35 series rear profile than the Yukon XL’s optional 50 series tires.
For better ride, handling and brake cooling the X7 has standard 21-inch wheels. Smaller 18-inch wheels are standard on the Yukon XL.
Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires standard on the X7 can be driven up to 50 miles without any air pressure, allowing you to drive to a service station for a repair. The Yukon XL doesn’t offer run-flat tires.
The front and rear suspension of the X7 uses air springs for a smoother, controlled ride than the Yukon XL, which uses coil springs. Air springs maintain proper ride height and ride more smoothly.
The X7 is 1 foot, 9.9 inches shorter than the Yukon XL, making the X7 easier to handle, maneuver and park in tight spaces.
Unibody construction lowers the X7’s center of gravity significantly without reducing ground clearance. This contributes to better on the road handling and better off-road performance and stability. In addition, unibody construction makes the chassis stiffer, improving handling and reducing squeaks and rattles. The Yukon XL uses body-on-frame design instead.
Unlike the driver-only memory system in the Yukon XL SLT/AT4/Denali, the X7 offers an optional passenger memory, so that when drivers switch, the memory setting adjusts the driver’s seat, steering wheel position, outside mirror angle, climate settings and radio stations and the front passenger seat also adjusts to the new passenger’s preset preferences.
The X7’s front and rear power windows all open or close with one touch of the switches, making it more convenient at drive-up windows and toll booths, or when talking with someone outside of the car. The Yukon XL’s rear power window switches have to be held the entire time to close them fully.
If the windows are left open on the X7 the driver can close them all at the outside door handle or from a distance using the remote. On a hot day the driver can lower the windows from a distance using the keyless remote. The driver of the Yukon XL can only operate the windows from inside the vehicle, with the ignition on.
To help drivers see further while navigating curves, the X7 has standard adaptive headlights to illuminate around corners automatically by reading vehicle speed and steering wheel angle. The Yukon XL doesn’t offer cornering lights.
Manual rear side window sunshades are available in the X7 to help block heat and glare for the rear passengers. The Yukon XL doesn’t offer rear side window sunshades.
The X7 has standard heated front and optional heated second and third row seats, which keep the driver and passengers extremely comfortable in the winter. GMC doesn’t offer heated seats in the third row of the Yukon XL.
The X7 offers optional massaging front seats in order to maximize comfort and eliminate fatigue on long trips. Massaging seats aren’t available in the Yukon XL.
To quickly and conveniently keep personal devices charged without cables tangling and wearing out, the BMW X7 has a standard wireless phone charging system (Qi) in the center console. Only the Yukon XL SLT/AT4/Denali offers wireless charging.
The X7’s optional Parking Assistant Plus can parallel park or back into a parking spot by itself, starting, stopping and changing direction automatically. The Yukon XL doesn’t offer an automated parking system.
