Compare the2023 BMW X7VS 2023 Mercedes AMG 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 AMG GLS doesn’t offer height-adjustable middle seat belts.

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 AMG GLS doesn’t offer a front passenger side knee airbag.

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 AMG GLS doesn’t offer automatic braking for stationary objects directly to the rear.

Both the X7 and the AMG 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, post-collision automatic braking systems, 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.

On the EPA test cycle the X7 gets better mileage than the AMG 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 AMG GLS doesn’t offer launch control.

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 AMG GLS 63’s standard 50 series front tires. The X7’s optional 275/35R23 front and 315/30R23 rear tires have a lower 35 series front and 30 series rear profile than the AMG 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 AMG 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 AMG GLS doesn’t offer an active sway bar system.

The BMW X7 may be more efficient, handle and accelerate better because it weighs about 50 to 600 pounds less than the Mercedes AMG GLS.

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 AMG GLS doesn’t offer active grille shutters.

The X7 has 2.5 inches more front headroom and .7 inches more front shoulder room than the AMG GLS.

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

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

The X7’s rear cargo window opens separately from the rest of the tailgate door to allow quicker loading of small packages. The AMG 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 AMG GLS.

J.D. Power and Associates surveys of service recipients show that BMW service is better than Mercedes. J.D. Power ranks BMW 7th in service department satisfaction (above the industry average). With a 17% lower rating, Mercedes is ranked 18th.

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 AMG GLS has neither an oil pressure gauge nor a temperature 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 AMG GLS.

The X7’s Parking Assistant Plus 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 AMG GLS’ automatic parking system does not offer parking by remote control.
