Safety

The AMG GLC 63’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Bentayga doesn’t offer pre-crash pretensioners.

The AMG GLC 63’s 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.

The AMG GLC 63 has standard Mercedes-Benz Emergency Call, which uses a global positioning satellite (GPS) receiver and a cellular system to remotely unlock your doors if you lock your keys in, help track down your vehicle if it’s stolen or send emergency personnel to the scene if any airbags deploy. The Bentayga doesn’t offer a GPS response system, only a navigation computer with no live response for emergencies, so if you’re involved in an accident and you’re incapacitated help may not come as quickly.

Both the AMG GLC 63 and the Bentayga have standard driver and passenger frontal airbags, front 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 lane departure warning systems and rear parking sensors.

Warranty

The AMG GLC 63 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 AMG GLC 63’s corrosion warranty is 2 years longer than the Bentayga’s (5 vs. 3 years).

There are over 8 times as many Mercedes dealers as there are Bentley dealers, which makes it much easier should you ever need service under the AMG GLC 63’s warranty.

Environmental Friendliness

In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the Mercedes AMG GLC 63 higher (5 out of 10) than the Bentley Bentayga (3). This means the AMG GLC 63 produces up to 16.5 pounds less smog-producing pollutants than the Bentayga every 15,000 miles.

Transmission

A nine-speed automatic is standard on the Mercedes AMG GLC 63, for better acceleration and lower engine speed on the highway. Only an eight-speed automatic is available for the Bentayga.

The AMG GLC 63’s launch control uses engine electronics to hold engine RPM’s precisely in order to provide the most stable and rapid acceleration possible, using all of the available traction. The Bentayga doesn’t offer launch control.

Tires and Wheels

For better traction and acceleration, the AMG GLC 63 has larger rear tires than the Bentayga (295/40R20 vs. 275/50R20). The AMG GLC 63’s rear tires are larger than the largest rear tires available on the Bentayga (295/40R20 vs. 285/45R21).

The AMG GLC 63’s standard 265/45R20 front and 295/40R20 rear tires provide better handling because they have a lower 45 series front and 40 series rear profile (height to width ratio) that provides a stiffer sidewall than the Bentayga’s standard 50 series tires. The AMG GLC 63’s optional 295/35R21 rear tires have a lower 35 series profile than the Bentayga’s optional 40 series tires.

Suspension and Handling

The AMG GLC 63’s 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 better maneuverability, the AMG GLC 63’s turning circle is .9 feet tighter than the Bentayga’s (39.7 feet vs. 40.6 feet).

Chassis

The Mercedes AMG GLC 63 may be more efficient, handle and accelerate better because it weighs about 800 to 900 pounds less than the Bentley Bentayga.

The AMG GLC 63 is 1 foot, 6.1 inches shorter than the Bentayga, making the AMG GLC 63 easier to handle, maneuver and park in tight spaces.

Cargo Capacity

The AMG GLC 63’s standard 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.

Ergonomics

Heated windshield washer nozzles are standard on the AMG GLC 63 to prevent washer fluid and nozzles from freezing and help continue to keep the windshield clear in sub-freezing temperatures. The Bentayga doesn’t offer heated windshield washer nozzles.

The AMG GLC 63 has a 115-volt a/c outlet, 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.

Model Availability

The Mercedes AMG GLC 63 comes in traditional 4-door sport utility and 4-door coupe bodystyles; the Bentley Bentayga isn’t available as a coupe style sport utility.
