Safety

Both the Aviator and GLC Coupe have child safety locks to prevent children from opening the rear doors. The Aviator 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 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.

The Aviator has standard Post Collision Braking, which automatically apply the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The GLC Coupe doesn’t offer a post collision braking system: in the event of a collision that triggers the airbags, more collisions are possible without the protection of airbags that may have already deployed.

Over 200 people are killed each year when backed over by motor vehicles. The Aviator (except Base) offers an optional Reverse Brake Assist that use rear sensors to monitor and automatically apply the brakes to prevent a rear collision. The GLC Coupe doesn’t offer backup collision prevention brakes.

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

To help make backing safer, the Aviator’s cross-path warning system uses wide-angle radar in the rear bumper to alert the driver to vehicles approaching from the side, helping the driver avoid collisions. The GLC Coupe doesn’t offer a cross-path warning system.

Both the Aviator and the GLC Coupe have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front and rear seatbelt pretensioners, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, rearview cameras, driver alert monitors, available all wheel drive and around view monitors.

The Lincoln Aviator weighs 619 to 1633 pounds more than the Mercedes GLC Coupe. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.

Warranty

Lincoln’s powertrain warranty covers the Aviator 2 years and 20,000 miles longer than Mercedes covers the GLC Coupe. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 6 years or 70,000 miles. Coverage on the GLC Coupe ends after only 4 years or 50,000 miles.

There are over 2 times as many Lincoln dealers as there are Mercedes dealers, which makes it much easier should you ever need service under the Aviator’s warranty.

Reliability

The Lincoln Aviator’s engines use a cast iron block for durability, while the GLC Coupe’s engines use an aluminum block. Aluminum engine blocks are much more prone to warp and crack at high temperatures than cast iron.

The Aviator has a standard “limp home system” to keep drivers from being stranded if most or all of the engine’s coolant is lost. The engine will run on only half of its cylinders at a time, reduce its power and light a warning lamp on the dashboard so the driver can get to a service station for repairs. The GLC Coupe doesn’t offer a lost coolant limp home mode, so a coolant leak could strand you or seriously damage the truck’s engine.

To reliably power the ignition and other systems and to recharge the battery, the Aviator has a standard -amp alternator (250-amp - Aviator optional). The GLC Coupe’s 150-amp alternator isn’t as powerful.

J.D. Power and Associates’ 2019 Initial Quality Study of new car owners surveyed provide the statistics that show that Lincoln vehicles are better in initial quality than Mercedes vehicles. J.D. Power ranks Lincoln fifth in initial quality, above the industry average. With 10 more problems per 100 vehicles, Mercedes is ranked 12th, below the industry average.

Engine

The Aviator’s standard 3.0 turbo V6 produces 159 more horsepower (400 vs. 241) and 142 lbs.-ft. more torque (415 vs. 273) than the GLC 300 Coupe’s standard 2.0 turbo 4 cyl. The Aviator’s 3.0 turbo V6 produces 38 more horsepower (400 vs. 362) and 31 lbs.-ft. more torque (415 vs. 384) than the AMG GLC 43 Coupe’s standard 3.0 turbo V6. The Aviator’s optional 3.0 turbo V6 hybrid produces 132 more horsepower (494 vs. 362) and 246 lbs.-ft. more torque (630 vs. 384) than the AMG GLC 43 Coupe’s standard 3.0 turbo V6.

Fuel Economy and Range

Regenerative brakes improve the Aviator Hybrid’s fuel efficiency by converting inertia back into energy instead of wasting it. The GLC Coupe doesn’t offer a regenerative braking system.

To lower fuel costs and make buying fuel easier, the Lincoln Aviator uses regular unleaded gasoline (premium recommended for maximum performance). The GLC Coupe requires premium, which can cost 20 to 55 cents more per gallon.

The Aviator’s standard fuel tank has 2.8 gallons more fuel capacity than the GLC Coupe (20.2 vs. 17.4 gallons).

The Aviator has a standard cap-less fueling system. The fuel filler is automatically opened when the fuel nozzle is inserted and automatically closed when it’s removed. This eliminates the need to unscrew and replace the cap and it reduces fuel evaporation, which causes pollution. The GLC Coupe doesn’t offer a cap-less fueling system.

Transmission

A 10-speed automatic is standard on the Lincoln Aviator, for better acceleration and lower engine speed on the highway. Only a nine-speed automatic is available for the GLC Coupe.

Tires and Wheels

For better traction, the Aviator has larger tires than the GLC Coupe (255/55R19 vs. 235/55R19).

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

The Aviator has a standard space-saver spare tire so you can replace a flat tire and drive to have the flat repaired or replaced. A spare tire isn’t available on the GLC Coupe; it requires you to depend on its run-flat tires, which limits mileage and speed before they are repaired. If a run-flat is damaged beyond repair by a road hazard your vehicle will have to be towed.

Suspension and Handling

For a smoother ride and more stable handling, the Aviator’s wheelbase is 6 inches longer than on the GLC Coupe (119.1 inches vs. 113.1 inches).

For better handling and stability, the track (width between the wheels) on the Aviator is 3.1 inches wider in the front and 3.2 inches wider in the rear than on the GLC Coupe.

Chassis

The front grille of the Aviator uses electronically controlled shutters to close off airflow and reduce drag when less engine cooling is needed. This helps improve highway fuel economy. The GLC Coupe doesn’t offer active grille shutters.

The Aviator Grand Touring/Black Label uses computer-generated active noise cancellation to help remove annoying noise and vibration from the passenger compartment, especially at low frequencies. The GLC Coupe doesn’t offer active noise cancellation.

Passenger Space

The Aviator has standard seating for 7 passengers; the GLC Coupe can only carry 5.

The Aviator has 2.6 inches more front headroom, 2.2 inches more front legroom, 4.2 inches more front shoulder room, 1.4 inches more rear headroom, 2.9 inches more rear legroom and 5.5 inches more rear shoulder room than the GLC Coupe.

Cargo Capacity

The Aviator’s cargo area provides more volume than the GLC Coupe.

Ergonomics

The Aviator has a standard remote vehicle starting system, so the vehicle can be started from inside the driver's house. This allows the driver to comfortably warm up the engine before going out to the vehicle. The climate system will also automatically heat or cool the interior. The GLC Coupe doesn’t offer a remote starting system.

In case you lock your keys in your vehicle, or don’t have them with you, you can let yourself in using the Aviator’s exterior PIN entry system. The GLC Coupe doesn’t offer an exterior PIN entry system, and its Mercedes-Benz Emergency Call can’t unlock the doors if the vehicle doesn’t have cell phone reception or the driver can’t contact the service.

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

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