Compare the2024 Lincoln NavigatorVS 2024 Mercedes GLS

In the past twenty years hundreds of infants and young children have died after being left in vehicles, usually by accident. When turning the vehicle off, drivers of the Navigator are reminded to check the back seat if they opened the rear door before starting out. The GLS doesn’t offer a back seat reminder.

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

The middle row seatbelts optional on the Navigator Reserve/Black Label inflate when a collision is detected, helping to spread crash forces over a much larger area of the body and limiting head and neck movement. This can help prevent spinal and internal injuries. The GLS doesn’t offer inflatable seatbelts.

Over 200 people are killed each year when backed over by motor vehicles. The Navigator has standard Reverse Brake Assist that uses rear sensors to monitor for objects to the rear and automatically applies the brakes to prevent a collision. The GLS doesn’t offer automatic braking for stationary objects directly to the rear.

The Navigator’s standard lane departure warning system alerts a temporarily inattentive driver when the vehicle begins to leave its lane and gently nudges the vehicle back towards its lane. A lane departure warning system costs extra on the GLS.

Both the Navigator and the GLS have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front 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 driver alert monitors.

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

There are over 78 percent more Lincoln dealers than there are Mercedes dealers, which makes it much easier should you ever need service under the Navigator’s warranty.

The Navigator 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 reduce its power and light a warning lamp on the dashboard so the driver can get to a service station for repairs. The GLS doesn’t offer a lost coolant limp home mode, so a coolant leak could strand you or seriously damage the truck’s engine.

A reliable vehicle saves its owner time, money and trouble. Nobody wants to be stranded or have to be without a vehicle while it’s being repaired. Consumer Reports rates the Navigator’s reliability 20 points higher than the GLS.

J.D. Power and Associates’ 2022 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that Lincoln vehicles are more reliable than Mercedes vehicles. J.D. Power ranks Lincoln above average in long-term dependability. With 12 more problems per 100 vehicles in the first three years of ownership, Mercedes is rated below average.

From surveys of all its subscribers, Consumer Reports’ January 2023 Auto Issue reports that Lincoln vehicles are more reliable than Mercedes vehicles. Consumer Reports ranks Lincoln 14 places higher in reliability than Mercedes.

The Navigator’s 3.5 turbo V6 produces 65 more horsepower (440 vs. 375) and 141 lbs.-ft. more torque (510 vs. 369) than the GLS 450’s standard 3.0 turbo 6-cylinder hybrid.

As tested in Car and Driver the Lincoln Navigator is faster than the GLS 450 3.0 turbo 6-cylinder hybrid:

On the EPA test cycle the Navigator gets better fuel mileage than the GLS 580 (16 city/22 hwy vs. 14 city/20 hwy).

To lower fuel costs and make buying fuel easier, the Lincoln Navigator uses regular unleaded gasoline (premium recommended for maximum performance). The GLS requires premium, which can cost on average about 82.8 cents more per gallon.

The Navigator 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 GLS doesn’t offer a cap-less fueling system.

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

The Lincoln Navigator’s wheels have 6 lugs for longer wheel bearing life, less chance of rotor warping and greater strength. The Mercedes GLS only has 5 wheel lugs per wheel.

For better handling and stability, the track (width between the wheels) on the Navigator is 1 inch wider in the front than the average track on the GLS.

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

The Navigator uses computer-generated active noise cancellation to help remove annoying noise and vibration from the passenger compartment, especially at low frequencies. The GLS doesn’t offer active noise cancellation.

The Navigator offers optional seating for 8 passengers; the GLS can only carry 7.

The Navigator has 2.4 inches more front headroom, 3.6 inches more front legroom, 5.9 inches more front shoulder room, 6.6 inches more rear shoulder room, 1.5 inches more third row legroom and 13.9 inches more third row shoulder room than the GLS.

For enhanced passenger comfort on long trips the Navigator’s middle and third row seats recline. The GLS’ third row seats don’t recline.

The Navigator’s cargo area provides more volume than the GLS.

A low lift-over cargo hatch design makes loading and unloading the Navigator easier. The Navigator’s cargo hatch lift-over height is 29 inches, while the GLS’ liftover is 31.8 inches.

The Navigator’s cargo area is larger than the GLS’ in almost every dimension:

The Navigator’s rear cargo window opens separately from the rest of the liftgate door to allow quicker loading of small packages. The GLS’ rear cargo window doesn’t open.

Maximum trailer towing in the Mercedes GLS is limited to 7716 pounds. The Navigator offers up to a 8300 lbs. towing capacity.

The Navigator with optional equipment can be flat towed on all four wheels (dinghy towed), allowing recreational vehicle owners to bring it with them on the road. When they reach their destination, the Navigator can be unhitched and driven around locally. The GLS can’t be towed flat on the ground.

A Trailer Sway Control is standard on the Navigator, using the AdvanceTrac® sensors to detect trailer sway, then uses individual brakes to counteract any swaying and help keep the tow vehicle and trailer steady. A trailer sway program costs extra on the GLS.

In case you lock your keys in your vehicle, or don’t have them with you, you can let yourself in using the Navigator’s exterior PIN entry system. The GLS 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 Navigator has a standard rear variable intermittent wiper with a full on position. The rear wiper standard on the GLS only has an intermittent setting, so in a hard rain visibility isn’t as good.

Consumer Reports rated the Navigator’s headlight performance “Very Good,” a higher rating than the GLS’ headlights, which were rated “Good.”

The Navigator has a standard heated steering wheel to take the chill out of steering on extremely cold winter days before the vehicle heater warms up. A heated steering wheel costs extra on the GLS.

According to The Car Book by Jack Gillis, the Navigator is less expensive to operate than the GLS because typical repairs cost much less on the Navigator than the GLS, including $544 less for a water pump, $308 less for a muffler, $160 less for front brake pads, $523 less for a starter, $350 less for fuel injection, $177 less for a fuel pump and $196 less for front struts.

A group of representative automotive journalists from North America selected the Navigator as the 2018 North American Truck of the Year. The GLS has never been chosen.
