Compare the2022 Mercedes GLSVS 2022 Bentley Bentayga

The Mercedes GLS has a standard driver’s side knee airbag mounted low on the dashboard. The knee airbag helps prevent the driver from sliding under the seatbelts or the main frontal airbag; this keeps the driver better positioned during a collision for maximum protection. A knee airbag also helps keep the legs from striking the dashboard, preventing knee and leg injuries in the case of a serious frontal collision. The Bentayga doesn’t offer knee airbags.

The GLS’ driver alert monitor detects an inattentive driver then sounds a warning and suggests a break. According to the NHTSA, drivers who fall asleep cause about 100,000 crashes and 1500 deaths a year. The Bentayga doesn’t offer a driver alert monitor.

Both the GLS and the Bentayga 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, plastic fuel tanks, four-wheel antilock brakes, all wheel drive, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, blind spot warning systems, around view monitors, rear cross-path warning and available lane departure warning systems.

The GLS comes with a full 4-year/50,000-mile basic warranty, which covers the entire truck and includes 24-hour roadside assistance. The Bentayga’s 3-year basic warranty expires 1 year sooner.

The GLS’ corrosion warranty is 2 years longer than the Bentayga’s (5 vs. 3 years).

There are almost 8 times as many Mercedes dealers as there are Bentley dealers, which makes it much easier should you ever need service under the GLS’ warranty.

On the EPA test cycle the GLS gets better mileage than the Bentayga:

Regenerative brakes improve the GLS’ fuel efficiency by converting inertia back into energy instead of wasting it. The Bentayga doesn’t offer a regenerative braking system.

The GLS has 1.3 gallons more fuel capacity than the Bentayga (23.8 vs. 22.5 gallons), for longer range between fill-ups.

A nine-speed automatic is standard on the Mercedes GLS, for better acceleration and lower engine speed on the highway. Only an eight-speed automatic is available for the Bentayga.

The GLS stops much shorter than the Bentayga:

The GLS’ optional 325/35R23 rear tires provide better handling because they have a lower 35 series profile (height to width ratio) that provides a stiffer sidewall than the Bentayga’s optional 40 series tires.

For better ride, handling and brake cooling the GLS offers optional 23-inch wheels. The Bentayga’s largest wheels are only 22-inches.

The GLS’ drift compensation steering can automatically compensate for road conditions which would cause the vehicle to drift from side to side, helping the driver to keep the vehicle straight more easily. The Bentayga doesn’t offer drift compensation steering.

For a smoother ride and more stable handling, the GLS’ wheelbase is 5.5 inches longer than on the Bentayga (123.4 inches vs. 117.9 inches).

The GLS 450 handles at .92 G’s, while the Bentayga pulls only .78 G’s of cornering force in a Car and Driver skidpad test.

For greater off-road capability the GLS has a greater minimum ground clearance than the Bentayga (10.1 vs. 9.7 inches), allowing the GLS to travel over rougher terrain without being stopped or damaged. The GLS Off-Road Package’s minimum ground clearance is 1.6 inches higher than on the Bentayga (11.3 vs. 9.7 inches).

The GLS has .6 inches more front shoulder room, 2.2 inches more rear headroom, 1 inch more rear legroom and .7 inches more rear shoulder room than the Bentayga.

The GLS’ cargo area provides more volume than the Bentayga.

The GLS’ available rear seats fold to accommodate long and bulky cargo. The Bentayga w/Four Seat Comfort Specification doesn’t offer folding rear seats, only a ski pass-through.

The GLS’ standard towing capacity is much higher than the Bentayga’s (7700 vs. 7165 pounds).

If the windows are left open on the GLS the driver can close them all at the outside door handle or from a distance using the remote. On a hot day the driver can lower the windows from a distance using the keyless remote. The driver of the Bentayga can only operate the windows from inside the vehicle, with the ignition on.

The GLS’ power window, power lock, power mirror and cruise control switches are lit from behind, making them plainly visible and easier to operate at night. The Bentayga’s cruise control switches are unlit, making them difficult to find at night and operate safely.

Heated windshield washer fluid is optional on the GLS to defrost the washer nozzles and quickly clear ice and frost from the windshield without scraping. The Bentayga doesn’t offer heated windshield washer fluid. Its standard heated washer nozzles will defrost the washer fluid but not the windshield.

The GLS has standard heated front and optional heated second and third row seats, which keep the driver and passengers extremely comfortable in the winter. Bentley doesn’t offer heated seats in the third row of the Bentayga.

The GLS has a 115-volt a/c outlet on the center console, allowing you to recharge a laptop or run small household appliances without special adapters that can break or get misplaced. The Bentayga doesn’t offer a house-current electrical outlet.

The GLS’ Active Parking Assist can parallel park or back into a parking spot by itself, starting, stopping and changing direction automatically. The Bentayga’s automatic parking system requires operating the brakes and transmission to safely park.

The Mercedes GLS outsold the Bentley Bentayga by over 23 to one during the 2021 model year.
