Compare the2022 Audi SQ8VS 2021 Mercedes G-Class

Both the SQ8 and G-Class have child safety locks to prevent children from opening the rear doors. The SQ8 has power child safety locks, allowing the driver to activate and deactivate them from the driver's seat and to know when they're engaged. The G-Class’ child locks have to be individually engaged at each rear door with a manual switch. The driver can’t know the status of the locks without opening the doors and checking them.

The SQ8’s standard pretensioning seatbelts also sense rear collisions and remove slack from the seatbelts to help protect the occupants from whiplash and other injuries. The G-Class doesn’t offer a whiplash protection system.

The SQ8 has a standard Secondary Collision Brake Assist, 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.

A passive infrared night vision system optional on the SQ8 Prestige helps the driver to more easily detect people, animals or other objects in front of the vehicle at night. Using an infrared camera to detect heat, the system then displays the image on a monitor in the dashboard. The G-Class doesn’t offer a night vision system.

The SQ8 has a standard Top View Cameras 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 SQ8 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 SQ8 and the G-Class have standard driver and passenger frontal airbags, front and rear side-impact airbags, side-impact head airbags, front and rear seatbelt pretensioners, height adjustable front shoulder belts, 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 and rear cross-path warning.

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 “Acceptable” rating, the Insurance Institute for Highway Safety grants the SQ8 the rating of “Top Pick” for 2021, a rating granted to only 135 vehicles tested by the IIHS. The G-Class has not been tested, yet.

The SQ8’s corrosion warranty is 7 years longer than the G-Class’ (12 vs. 5 years).

From surveys of all its subscribers, Consumer Reports’ January 2021 Auto Issue reports that Audi vehicles are more reliable than Mercedes vehicles. Consumer Reports ranks Audi 6 places higher in reliability than Mercedes.

The SQ8’s 4.0 turbo V8 hybrid produces 84 more horsepower (500 vs. 416) and 118 lbs.-ft. more torque (568 vs. 450) than the G 550’s standard 4.0 turbo V8.

On the EPA test cycle the SQ8 gets better fuel mileage than the AMG G 63 4.0 turbo V8 (15 city/21 hwy vs. 13 city/16 hwy).

Regenerative brakes improve the SQ8’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 SQ8’s brake rotors are larger than those on the G-Class:

For better traction, the SQ8 has larger tires than the G-Class (285/45R21 vs. 275/55R19).

The SQ8’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.

For better ride, handling and brake cooling the SQ8 has standard 21-inch wheels. Smaller 19-inch wheels are standard on the G 550.

For superior ride and handling, the Audi SQ8 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 SQ8 Prestige 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 front and rear suspension of the SQ8 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 SQ8 Prestige 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.

The SQ8 has a standard automatic front and rear load leveling suspension to keep ride height level with a heavy load or when towing. The SQ8’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 SQ8’s wheelbase is 4.1 inches longer than on the G-Class (117.9 inches vs. 113.8 inches).

For better handling and stability, the track (width between the wheels) on the SQ8 is 1.3 inches wider in the front and 1.8 inches wider in the rear than the average track on the G-Class.

For better maneuverability, the SQ8’s turning circle is 1 foot tighter than the G-Class’ (43.6 feet vs. 44.6 feet).

The Audi SQ8 may be more efficient, handle and accelerate better because it weighs about 250 to 500 pounds less than the Mercedes G-Class.

The SQ8 is 10.2 inches shorter in height than the G-Class, making the SQ8 much easier to wash and garage and drive (lower center of gravity).

Unibody construction lowers the SQ8’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 uses body-on-frame design instead.

The design of the Audi SQ8 amounts to more than styling. The SQ8 has an aerodynamic coefficient of drag of .35 Cd. That is significantly lower than the G-Class (.55). A more efficient exterior helps keep the interior quieter and helps the SQ8 get better fuel mileage.

For excellent aerodynamics, the SQ8 has standard flush composite headlights. The G-Class has recessed headlights that spoil its aerodynamic shape and create extra drag.

The SQ8 has 2.5 inches more front legroom, 1.7 inches more front shoulder room, .6 inches more rear legroom and 1.1 inches more rear shoulder room than the G-Class.

The SQ8’s liftgate lifts up in one piece, completely out of the way of loading and unloading, while sheltering the cargo loading area. The G-Class’ swing out door blocks loading from the driver’s side.

To make loading and unloading groceries and cargo easier when your hands are full, the SQ8’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.

The SQ8’s standard towing capacity is much higher than the G-Class’ (7700 vs. 7000 pounds).

The SQ8 Prestige has a standard heads-up display that projects speed 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 SQ8 has standard extendable sun visors. The G-Class doesn’t offer extendable visors.

A manual rear sunshade and power rear side window sunshades are optional in the SQ8 to help block heat and glare for the rear passengers. The G-Class doesn’t offer a rear or rear side window sunshades.

The SQ8 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 Audi Q8/SQ8/RS Q8 outsold the Mercedes G-Class by 77% during the 2021 model year.
