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 G-Class 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 G-Class doesn’t offer a back seat reminder.

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 G-Class doesn’t offer a whiplash protection system.

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 G-Class 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.

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 G-Class doesn’t offer automatic braking for stationary objects directly to the rear.

The X7 offers an optional Surround View to allow the driver to see objects all around the vehicle on a screen. The G-Class only offers a rear monitor and front and rear parking sensors that beep or flash a light. That doesn’t help with obstacles to the sides.

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 G-Class uses a body-on-frame design, which has no frame members above the floor of the vehicle.

Both the X7 and the G-Class have standard driver and passenger frontal airbags, front and rear side-impact airbags, driver and front passenger 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 and driver alert monitors.

Warranty

The X7’s corrosion warranty is 7 years longer than the G-Class’ (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 G-Class.

Reliability

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.

Engine

The X7 has more powerful engines than the G-Class:

	Horsepower
X7 M60i 4.4 turbo V8 hybrid	523 HP
Alpina XB7 4.4 turbo V8	631 HP
G 550 4.0 turbo V8	416 HP
AMG G 63 4.0 turbo V8	577 HP

As tested in Motor Trend the X7 xDrive40i 3.0 turbo 6-cylinder hybrid is faster than the G 550:

	X7	G-Class
Zero to 60 MPH	4.8 sec	5.4 sec
Quarter Mile	13.5 sec	14.1 sec
Speed in 1/4 Mile	101.6 MPH	98.4 MPH

Fuel Economy and Range

On the EPA test cycle the X7 gets better mileage than the G-Class:

			MPG
X7
	AWD	3.0 turbo 6-cyl. Hybrid	20 city/24 hwy
		M60i 4.4 turbo V8	16 city/20 hwy
		Alpina XB7 4.4 turbo V8	16 city/20 hwy
G-Class
	AWD	550 4.0 turbo V8	13 city/16 hwy
		63 4.0 turbo V8	13 city/16 hwy

Regenerative brakes improve the X7’s fuel efficiency by converting inertia back into energy instead of wasting it. The G-Class doesn’t offer a regenerative braking system.

Environmental Friendliness

In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the BMW X7 higher (5 to 7 out of 10) than the Mercedes G-Class (3). This means the X7 produces up to 24.5 pounds less smog-producing pollutants than the G-Class every 15,000 miles.

Brakes and Stopping

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

	X7 M Sport	G 550	AMG G 63
Front Rotors	15.6 inches	13.9 inches	14.8 inches
Rear Rotors	14.6 inches	13.6 inches	13 inches

The X7 stops much shorter than the G-Class:

	X7	G-Class
60 to 0 MPH	105 feet	136 feet	Motor Trend

Tires and Wheels

For better traction and acceleration, the X7 has larger standard rear tires than the G-Class (315/35R22 vs. 275/55R19). The Alpina XB7’s rear tires are larger than the largest rear tires available on the G-Class (325/30R23 vs. 295/40R22).

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 G 550’s standard 55 series 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 G-Class’ optional 40 series tires.

For better ride, handling and brake cooling the X7 has standard 21-inch wheels. Smaller 19-inch wheels are standard on the G 550. The X7’s optional 23-inch wheels are larger than the 22-inch wheels optional on the G-Class.

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 G-Class doesn’t offer run-flat tires.

Suspension and Handling

For superior ride and handling, the BMW X7 has fully independent front and rear suspensions. An independent suspension allows the wheels to follow the road at the best angle for gripping the pavement, without compromising ride comfort. The Mercedes G-Class has a solid rear axle, with a non-independent rear suspension.

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 G-Class doesn’t offer an active sway bar system.

The front and rear suspension of the X7 uses air springs for a smoother, controlled ride than the G-Class, which uses coil springs. Air springs maintain proper ride height and ride more smoothly.

The X7 offers an available active suspension system, which counteracts cornering forces actively, limiting body roll and improving handling and stability. Mercedes doesn’t offer an active suspension on the G-Class.

The X7 has a standard automatic front and rear load leveling suspension to keep ride height level with a heavy load or when towing. The X7’s height leveling suspension allows the driver to raise ride height for better off-road clearance and then lower it again for easier entering and exiting and better on-road handling. The G-Class doesn’t offer a load leveling suspension.

For a smoother ride and more stable handling, the X7’s wheelbase is 8.4 inches longer than on the G-Class (122.2 inches vs. 113.8 inches).

For better handling and stability, the average track (width between the wheels) on the X7 is 1.6 inches wider in the front and 2 inches wider in the rear than the average track on the G-Class.

The X7 xDrive40i handles at .88 G’s, while the G 550 pulls only .61 G’s of cornering force in a Motor Trend skidpad test.

The X7 xDrive40i executes Motor Trend’s “Figure Eight” maneuver 4.6 seconds quicker than the G 550 (26.1 seconds @ .7 average G’s vs. 30.7 seconds @ .53 average G’s).

For better maneuverability, the X7 w/Rear Steering’s turning circle is 3.9 feet tighter than the G-Class’ (40.7 feet vs. 44.6 feet). The X7 xDrive40i’s turning circle is 1.9 feet tighter than the G-Class’ (42.7 feet vs. 44.6 feet).

Chassis

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 G-Class doesn’t use unibody construction, but a body-on-frame design.

For excellent aerodynamics, the X7 has standard flush composite headlights. The G-Class has recessed headlights that spoil its aerodynamic shape and create extra drag.

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 G-Class doesn’t offer active grille shutters.

Passenger Space

The X7 has standard seating for 7 passengers; the G-Class can only carry 5.

The X7 has 1.1 inches more front legroom, 2.2 inches more front shoulder room and .7 inches more rear shoulder room than the G-Class.

Cargo Capacity

The X7’s cargo area provides more volume than the G-Class.

	X7	G-Class
Third Seat Folded	48.6 cubic feet	n/a
Third Seat Removed	n/a	38.1 cubic feet
Second Seat Folded	90.4 cubic feet	68.6 cubic feet

Pressing a button automatically lowers or raises the X7’s second and third row seats, to make changing between cargo and passengers easier. The G-Class doesn’t offer automatic folding second row seats.

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

To make loading and unloading groceries and cargo easier when your hands are full, the X7’s power cargo door can be opened or closed just by kicking your foot under the back bumper, leaving your hands completely free. The G-Class doesn’t offer a power or hands-free opening cargo door.

Towing

Maximum trailer towing in the Mercedes G-Class is limited to 7000 pounds. The X7 offers up to a 7500 lbs. towing capacity.

Ergonomics

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 G-Class does not have an oil pressure gauge.

The X7 has a standard heads-up display that projects speed, tachometer, warning, navigation instruction and driver assistance information readouts in front of the driver’s line of sight, allowing drivers to view information without diverting their eyes from the road. The G-Class doesn’t offer a heads-up display.

The X7’s standard Comfort Access allow you to unlock the doors from any outside door handle, open the cargo door, and start the engine, all without removing the key from the pocket or purse. Keyless-Start standard on the G-Class only offers hands-free access for the ignition, none to unlock the vehicle.

To shield the driver and front passenger’s vision over a larger portion of the windshield and side windows, the X7 has standard extendable sun visors. The G-Class doesn’t offer extendable visors.

Manual rear side window sunshades are available in the X7 to help block heat and glare for the rear passengers. The G-Class doesn’t offer rear side window sunshades.

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 G-Class.

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 G-Class’ automatic parking system does not offer parking by remote control.
