Safety

The AMG GLE 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 GLE 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 GLE 63 has standard mbrace, 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 GLE 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 and rearview cameras.

Warranty

The AMG GLE 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 GLE 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 GLE 63’s warranty.

Fuel Economy and Range

On the EPA test cycle the AMG GLE 63 gets better fuel mileage than the Bentayga W12 (14 city/18 hwy vs. 12 city/19 hwy).

The AMG GLE 63 Coupe’s standard fuel tank has 1.5 gallons more fuel capacity than the Bentayga (24 vs. 22.5 gallons), for longer range between fill-ups. The AMG GLE 63’s standard fuel tank has 2.1 gallons more fuel capacity than the Bentayga (24.6 vs. 22.5 gallons).

Tires and Wheels

For better traction, the AMG GLE 63’s optional tires are larger than the largest tires available on the Bentayga (295/35R21 vs. 285/45R21).

The AMG GLE 63’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 Bentayga’s standard 50 series tires. The AMG GLE 63’s optional tires have a lower 35 series profile than the Bentayga’s optional 40 series tires.

Suspension and Handling

The AMG GLE 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.

The AMG GLE 63’s front to rear weight distribution is more even (54.7% to 45.3%) than the Bentayga’s (57.5% to 42.5%). This gives the AMG GLE 63 more stable handling and braking.

The AMG GLE 63 S Coupe handles at .95 G’s, while the Bentayga pulls only .78 G’s of cornering force in a Car and Driver skidpad test.

The AMG GLE 63 S Coupe executes Motor Trend’s “Figure Eight” maneuver quicker than the Bentayga (25.2 seconds @ .77 average G’s vs. 25.6 seconds @ .74 average G’s).

For better maneuverability, the AMG GLE 63’s turning circle is 1.9 feet tighter than the Bentayga’s (38.7 feet vs. 40.6 feet).

Chassis

The AMG GLE 63 Coupe is 11.4 inches shorter than the Bentayga, making the AMG GLE 63 easier to handle, maneuver and park in tight spaces.

Cargo Capacity

The AMG GLE 63 Coupe has a much larger cargo area with its rear seat up than the Bentayga (23 vs. 17.1 cubic feet).

The AMG GLE 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 fluid is optional on the AMG GLE 63 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.

The AMG GLE 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.
