Both the Bentayga and AMG GLC Coupe have child safety locks to prevent children from opening the rear doors. The Bentayga 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 AMG GLC Coupe’s 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.

When descending a steep, off-road slope, the Bentayga’s standard Hill Descent Control allows you to creep down safely. The AMG GLC Coupe doesn’t offer Hill Descent Control.

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 AMG GLC Coupe doesn’t offer a night vision system.

Both the Bentayga and the AMG GLC Coupe have standard driver and passenger frontal airbags, front 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, daytime running lights, blind spot warning systems, rearview cameras, available crash mitigating brakes, lane departure warning systems, around view monitors and rear cross-path warning.

The Bentley Bentayga weighs 678 to 1541 pounds more than the Mercedes AMG GLC Coupe. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.

On the EPA test cycle the Bentayga Hybrid running on electricity gets better fuel mileage than the AMG GLC 43 Coupe (43 city/49 hwy MPGe vs. 18 city/24 hwy).

The Bentayga Hybrid can drive on battery power alone for up to 18 miles. The AMG GLC Coupe must run its internal combustion engine to move.

An engine control system that can shut down some of the engine’s cylinders (except Hybrid) helps improve the Bentayga’s fuel efficiency. The AMG GLC Coupe doesn’t offer a system that can shut down part of the engine.

The Bentayga Hybrid’s standard fuel tank has 2.4 gallons more fuel capacity than the AMG GLC Coupe (19.8 vs. 17.4 gallons), for longer range between fill-ups. The Bentayga’s standard fuel tank has 5.1 gallons more fuel capacity than the AMG GLC Coupe (22.5 vs. 17.4 gallons).

For better traction, the Bentayga has larger standard tires than the AMG GLC Coupe (275/50R20 vs. 255/45R20). The Bentayga’s optional tires are larger than the largest tires available on the AMG GLC Coupe (285/45R21 vs. 265/45R20).

For better ride, handling and brake cooling the Bentayga offers optional 22-inch wheels. The AMG GLC Coupe’s largest wheels are only 21-inches.

The Bentayga has a standard full size spare tire so a flat doesn’t interrupt your trip. A full size spare isn’t available on the AMG GLC Coupe; it requires you to depend on a temporary spare or run-flat tires, either of which has mileage and speed limitations.

Suspension and Handling

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 AMG GLC Coupe doesn’t offer an active sway bar system.

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 AMG GLC Coupe.

The Bentayga has a standard driver-adjustable suspension system. It allows the driver to choose between an extra-supple ride, reducing fatigue on long trips, or a sport setting, which allows maximum control for tricky roads or off-road. The AMG GLC Coupe’s suspension doesn’t offer adjustable shock absorbers.

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 AMG GLC Coupe doesn’t offer a load leveling suspension.

For a smoother ride and more stable handling, the Bentayga’s wheelbase is 4.8 inches longer than on the AMG GLC Coupe (117.9 inches vs. 113.1 inches).

For better handling and stability, the track (width between the wheels) on the Bentayga is 1.1 inches wider in the front and 1.5 inches wider in the rear than the average track on the AMG GLC Coupe.

The Bentayga SPEED handles at .93 G’s, while the AMG GLC 43 Coupe pulls only .92 G’s of cornering force in a Motor Trend skidpad test.

The Bentayga SPEED executes Motor Trend’s “Figure Eight” maneuver quicker than the AMG GLC 43 Coupe (24.6 seconds @ .79 average G’s vs. 25 seconds @ .79 average G’s).

For better maneuverability, the Bentayga SPEED’s turning circle is .7 feet tighter than the AMG GLC Coupe’s (39 feet vs. 39.7 feet).

For greater off-road capability the Bentayga has a 3.5 inches greater minimum ground clearance than the AMG GLC 63 Coupe (9.7 vs. 6.2 inches), allowing the Bentayga to travel over rougher terrain without being stopped or damaged. The Bentayga’s minimum ground clearance is 3.3 inches higher than on the AMG GLC 63 S Coupe (9.7 vs. 6.4 inches).

The design of the Bentley Bentayga amounts to more than styling. The Bentayga has an aerodynamic coefficient of drag of .34 Cd. That is lower than the AMG GLC Coupe (.37). A more efficient exterior helps keep the interior quieter and helps the Bentayga get better fuel mileage.

As tested by Car and Driver, the interior of the Bentayga is quieter than the AMG GLC 63 S Coupe:

The Bentayga offers optional seating for 7 passengers; the AMG GLC Coupe can only carry 5.

The Bentayga has 1.4 inches more front headroom, .9 inches more front legroom, 1.4 inches more front shoulder room, 3.7 inches more rear legroom and 2 inches more rear shoulder room than the AMG GLC Coupe.

Flexibility is maximized at the game, campground or a drive-in theatre in the Bentayga when its optional tailgating rear seats are deployed, allowing people to sit facing out of the liftgate. (Do not use while vehicle is in motion.) The AMG GLC Coupe doesn’t offer tailgating seats.

To improve rear visibility by keeping the rear window clear, the Bentayga has a standard rear wiper. The AMG GLC Coupe doesn’t offer a rear wiper.

In poor weather, headlights can lose their effectiveness as grime builds up on their lenses. This can reduce visibility without the driver realizing. The Bentayga has standard headlight washers to keep headlight output high. The AMG GLC Coupe doesn’t offer headlight washers.

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 AMG GLC Coupe doesn’t offer air-conditioned seats in the rear.

On extremely cold winter days, the Bentayga’s optional heated steering wheel provides comfort, allowing the driver to steer safely and comfortably before the vehicle heater warms up. The AMG GLC Coupe doesn’t offer a heated steering wheel.

The Bentayga offers optional massaging front and second row seats, which keep the driver and middle row passengers. Massaging seats aren’t available in the AMG GLC Coupe.
