A passive infrared night vision system optional on the Bentayga 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 projects the image on the windshield, near the driver’s line of sight. The G-Class doesn’t offer a night vision system.

The Bentayga offers an optional Top 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 Bentayga 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 Bentayga and the G-Class have standard driver and passenger frontal airbags, front and rear side-impact airbags, side-impact head airbags, height adjustable front shoulder belts, four-wheel antilock brakes, all wheel drive, traction control, electronic stability systems to prevent skidding, daytime running lights, blind spot warning systems, rearview cameras, available crash mitigating brakes, lane departure warning systems and rear cross-path warning.

The Bentayga offers optional heat-treated ceramic brake rotors, which last ten to twenty times as long as conventional cast iron rotors, don’t rust, don’t fade during repeated high speed braking, and their lighter weight contribute to better braking, handling and acceleration. The G-Class doesn’t offer ceramic brake rotors.

For better traction, the Bentayga’s optional tires are larger than the largest tires available on the G-Class (285/45R21 vs. 275/55R19).

The Bentayga’s standard tires provide better handling because they have a lower 50 series profile (height to width ratio) that provides a stiffer sidewall than the G-Class’ standard 55 series tires. The Bentayga’s optional tires have a lower 40 series profile than the G-Class’ optional 50 series tires.

For better ride, handling and brake cooling the Bentayga has standard 20-inch wheels. Smaller 19-inch wheels are standard on the G-Class.

Suspension and Handling

For superior ride and handling, the Bentley Bentayga 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 Bentayga 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 Bentayga 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 Bentayga 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 Bentayga has a standard automatic front and rear load leveling suspension to keep ride height level with a heavy load or when towing. The Bentayga’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 Bentayga’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 Bentayga is 2 inches wider in the front and 2.2 inches wider in the rear than on the G-Class.

The Bentayga handles at .81 G’s, while the AMG G 63 pulls only .75 G’s of cornering force in a Car and Driver skidpad test.

The Bentayga SPEED executes Motor Trend’s “Figure Eight” maneuver 6.1 seconds quicker than the G 550 (24.6 seconds @ .79 average G’s vs. 30.7 seconds @ .53 average G’s).

For better maneuverability, the Bentayga SPEED’s turning circle is 5.6 feet tighter than the G-Class’ (39 feet vs. 44.6 feet). The Bentayga’s turning circle is 4 feet tighter than the G-Class’ (40.6 feet vs. 44.6 feet).

For greater off-road capability the Bentayga has a greater minimum ground clearance than the G-Class (9.7 vs. 9.5 inches), allowing the Bentayga to travel over rougher terrain without being stopped or damaged.

The Bentley Bentayga may be more efficient, handle and accelerate better because it weighs about 50 to 400 pounds less than the Mercedes G-Class.

The Bentayga is 8.6 inches shorter in height than the G-Class, making the Bentayga much easier to wash and garage and drive (lower center of gravity).

Unibody construction lowers the Bentayga’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.

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

The Bentayga offers optional seating for 7 passengers; the G-Class can only carry 5.

The Bentayga has 3 inches more front legroom, .9 inches more front shoulder room, 1.4 inches more rear legroom and .4 inches more rear shoulder room than the G-Class.

The Bentayga’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, especially for short adults, the Bentayga has a standard power liftgate, which opens and closes automatically by pressing a button, or optionally by just kicking your foot under the back bumper, completely leaving your hands free. The G-Class doesn’t offer a power cargo door.

The Bentayga offers an optional 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.

Optional air-conditioned the front and second row seats keep the Bentayga’s passengers comfortable and take the sting out of hot leather in summer. The G-Class doesn’t offer air-conditioned seats in the rear.
