Compare the2025 BMW X7VS 2024 Mercedes GLS

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 Mercedes GLS doesn’t offer height-adjustable middle 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 X7 are reminded to check the back seat if they opened the rear door before starting out. The GLS doesn’t offer a back seat reminder.

The BMW X7 has standard driver and front passenger side knee airbags mounted low on the dashboard. These airbags helps prevent the driver and front passenger from sliding under their seatbelts or the main frontal airbags; this keeps them better positioned during a collision for maximum protection. Knee airbags also help keep the legs from striking the dashboard, preventing knee and leg injuries in the case of a serious frontal collision. The GLS doesn’t offer a front passenger side knee airbag.

The X7 has standard Active Head Restraints, which use a specially designed headrest to protect the driver and front passenger from whiplash. During a rear-end collision, the Active Head Restraints system moves the headrests forward to prevent neck and spine injuries. The GLS doesn’t offer a whiplash protection system.

Over 200 people are killed each year when backed over by motor vehicles. The X7 has a standard Active Park Distance Control that uses rear sensors to monitor for objects to the rear and automatically applies the brakes to prevent a collision. The GLS doesn’t offer automatic braking for stationary objects directly to the rear.

Both the X7 and the GLS have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front seatbelt pretensioners, four-wheel antilock brakes, all wheel drive, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems, blind spot warning systems, rearview cameras, rear cross-path warning, driver alert monitors and available around view monitors.

The X7’s corrosion warranty is 7 years longer than the GLS’ (12 vs. 5 years).

BMW pays for scheduled maintenance on the X7 for 3 years and 36,000 miles. BMW will pay for oil changes, tire rotations, air filter replacements, cabin filter replacement, brake fluid replacement, inspections, and any other required maintenance. Mercedes doesn’t pay scheduled maintenance for the GLS.

J.D. Power and Associates’ 2024 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that BMW vehicles are more reliable than Mercedes With 28 fewer problems per 100 vehicles in the first three years of ownership, J.D. Power ranks BMW higher than Mercedes.

From surveys of all its subscribers, Consumer Reports’ January 2024 Auto Issue reports that BMW vehicles are more reliable than Mercedes vehicles. Consumer Reports ranks BMW 20 places higher in reliability than Mercedes.

The X7 has more powerful engines than the GLS:

As tested in Motor Trend the X7 xDrive40i 3.0 turbo 6-cylinder hybrid is faster than the GLS 450 3.0 turbo 6-cylinder hybrid:

On the EPA test cycle the X7 gets better mileage than the GLS:

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 GLS doesn’t offer launch control.

For better stopping power the X7 M Sport’s brake rotors are larger than those on the GLS:

The X7 stops much shorter than the GLS:

The X7’s optional 275/35R23 front and 315/30R23 rear tires provide better handling because they have a lower 35 series front and 30 series rear profile (height to width ratio) that provides a stiffer sidewall than the GLS’ optional 40 series front and 35 series rear tires.

Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires available 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 GLS doesn’t offer run-flat tires.

The X7 offers active sway bars, which help keep it flat and controlled during cornering, but disconnect at lower speeds to smooth the ride and offer greater off-road suspension articulation. This helps keep the tires glued to the road on-road and off. The GLS doesn’t offer an active sway bar system.

The X7 xDrive40i handles at .88 G’s, while the GLS 580 pulls only .83 G’s of cornering force in a Motor Trend skidpad test.

The X7 xDrive40i executes Motor Trend’s “Figure Eight” maneuver 1.1 seconds quicker than the GLS 580 (26.1 seconds @ .7 average G’s vs. 27.2 seconds @ .66 average G’s).

The front grille of the X7 uses electronically controlled shutters to close off airflow and reduce drag when less engine cooling is needed. This helps improve highway fuel economy. The GLS doesn’t offer active grille shutters.

For enhanced passenger comfort on long trips the X7’s middle and third row seats recline. The GLS’ third row seats don’t recline.

The X7’s cargo area provides more volume than the GLS.

The X7’s rear cargo window opens separately from the rest of the tailgate door to allow quicker loading of small packages. The GLS’ rear cargo window doesn’t open.

A Trailer Stabilization Control is standard on the X7, using the Dynamic Stability Control sensors to detect trailer sway, then uses individual brakes to counteract any swaying and help keep the tow vehicle and trailer steady. A trailer sway program costs extra on the GLS.

The X7’s instruments include an oil pressure gauge and a temperature gauge - which could save your engine! Often ‘idiot lights’ don’t warn you until damage has been done. The GLS does not have an oil pressure gauge.

The X7 has a standard heated steering wheel to take the chill out of steering on extremely cold winter days before the vehicle heater warms up. A heated steering wheel costs extra on the GLS.

The X7’s Parking Assistant can parallel park or back into a parking spot by itself, starting, stopping and changing direction automatically. Remote Control will park and retrieve your car remotely: press a button and watch it park itself. This is ideal for tight locations. The GLS’ automatic parking system does not offer parking by remote control.

Insurance will cost less for the X7 owner. The Complete Car Cost Guide estimates that insurance for the X7 will cost $265 less than the GLS over a five-year period.

IntelliChoice estimates that five-year ownership costs (depreciation, financing, insurance, fuel, fees, repairs and maintenance) for the BMW X7 will be $9905 to $23825 less than for the Mercedes GLS.
