Compare the2023 BMW X5 MVS 2023 Mercedes G-Class

The X5 M has a standard PostCrash iBrake, which automatically applies 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 X5 M 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 X5 M has a standard 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 X5 M 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 X5 M 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.

For its top level performance in IIHS driver and passenger-side small overlap frontal, moderate overlap frontal, side impact, roof strength and head restraint tests, its standard vehicle-to-vehicle front crash prevention system, its standard vehicle-to-pedestrian front crash prevention system, and its available headlight’s “Good” rating, the Insurance Institute for Highway Safety grants the X5 M the rating of “Top Safety Pick” for 2022, a rating granted to only 176 vehicles tested by the IIHS. The G-Class has not been tested, yet.

The X5 M’s corrosion warranty is 7 years longer than the G-Class’ (12 vs. 5 years).

BMW pays for scheduled maintenance on the X5 M for 3 years and 36,000 miles. BMW will pay for oil changes, lubrication and any other required maintenance. Mercedes doesn’t pay scheduled maintenance for the G-Class.

The X5 M’s standard 4.4 turbo V8 produces 184 more horsepower (600 vs. 416) and 103 lbs.-ft. more torque (553 vs. 450) than the G 550’s standard 4.0 turbo V8. The X5 M’s 4.4 turbo V8 produces 23 more horsepower (600 vs. 577) than the AMG G 63’s standard 4.0 turbo V8. The X5 M Competition’s standard 4.4 turbo V8 produces 40 more horsepower (617 vs. 577) than the AMG G 63’s standard 4.0 turbo V8.

On the EPA test cycle the X5 M gets better mileage than the G-Class:

Regenerative brakes improve the X5 M’s fuel efficiency by converting inertia back into energy instead of wasting it. The G-Class doesn’t offer a regenerative braking system.

For better stopping power the X5 M’s brake rotors are larger than those on the G-Class:

For better traction, the X5 M has larger tires than the G-Class (F:295/35R21 & R:315/30R21 vs. 275/55R19).

The X5 M’s 295/35R21 front and 315/30R21 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 G 550’s standard 55 series tires. The X5 M’s tires are lower profile than the G-Class’ optional 40 series tires.

For better ride, handling and brake cooling the X5 M has standard 21-inch wheels. Smaller 19-inch wheels are standard on the G 550.

For superior ride and handling, the BMW X5 M 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 X5 M has 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 rear suspension of the X5 M 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 X5 M offers an available adjustable 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.

For a smoother ride and more stable handling, the X5 M’s wheelbase is 3.2 inches longer than on the G-Class (117 inches vs. 113.8 inches).

For better handling and stability, the track (width between the wheels) on the X5 M is 2.1 inches wider in the front and 1.7 inches wider in the rear than the average track on the G-Class.

The X5 M’s front to rear weight distribution is more even (50.1% to 49.9%) than the G-Class’ (53% to 47%). This gives the X5 M more stable handling and braking.

For better maneuverability, the X5 M’s turning circle is 2.6 feet tighter than the G-Class’ (42 feet vs. 44.6 feet).

The X5 M is 8.5 inches shorter in height than the G-Class, making the X5 M much easier to wash and garage and drive (lower center of gravity).

Unibody construction lowers the X5 M’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.

The design of the BMW X5 M amounts to more than styling. The X5 M has an aerodynamic coefficient of drag of .38 Cd. That is significantly lower than the G-Class (.55). A more efficient exterior helps keep the interior quieter and helps the X5 M get better fuel mileage.

For excellent aerodynamics, the X5 M 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 X5 M 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.

The X5 M 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.

The X5 M has a larger cargo volume with its rear seat folded than the G-Class with its rear seat folded (72.3 vs. 68.6 cubic feet).

Pulling a handle automatically lowers the X5 M’s rear seats, to make changing between passengers and cargo easier. The G-Class doesn’t offer automatic folding seats.

The X5 M’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 X5 M’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.

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 X5 M has a standard heads-up display that projects speed, tachometer, warning and navigation instruction 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.

To shield the driver and front passenger’s vision over a larger portion of the windshield and side windows, the X5 M has standard extendable sun visors. The G-Class doesn’t offer extendable visors.

Manual rear side window sunshades are available in the X5 M to help block heat and glare for the rear passengers. The G-Class doesn’t offer rear side window sunshades.

The X5 M 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 BMW X5 outsold the Mercedes G-Class by almost 12 to one during 2022.
