For enhanced safety, the front and middle seat shoulder belts of the Mercedes GLS have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision and force limiters to limit the pressure the belts will exert on the passengers. The Lincoln Navigator L doesn’t offer pretensioners for the middle seat belts.

The GLS’ pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Navigator L doesn’t offer pre-crash pretensioners.

To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the GLS. But it costs extra on the Navigator L.

For better protection of the passenger compartment, the GLS uses safety cell construction with a three-dimensional high-strength frame that surrounds the passenger compartment. It provides extra impact protection and a sturdy mounting location for door hardware and side impact beams. The Navigator L uses a body-on-frame design, which has no frame members above the floor of the vehicle.

Both the GLS and the Navigator L have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, height adjustable front shoulder belts, plastic fuel tanks, four-wheel antilock brakes, 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, driver alert monitors and available lane departure warning systems.

The front and rear suspension of the GLS uses air springs for a smoother, controlled ride than the Navigator L, which uses coil springs. Air springs maintain proper ride height and ride more smoothly.

The GLS offers an available adjustable active suspension system, which counteracts cornering forces actively, limiting body roll and improving handling and stability. Lincoln doesn’t offer an active suspension on the Navigator L.

The GLS has a standard automatic front and rear load leveling suspension to keep ride height level with a heavy load or when towing. The GLS’ height leveling suspension allows the driver to raise ride height for better off-road clearance and then lower it again for easier entering and exiting and better on-road handling. The Navigator L doesn’t offer a load leveling suspension.

The GLS 580 handles at .90 G’s, while the Navigator L Black Label 4x4 pulls only .78 G’s of cornering force in a Car and Driver skidpad test.

For better maneuverability, the GLS’ turning circle is 3.9 feet tighter than the Navigator L’s (39.4 feet vs. 43.3 feet).

For greater off-road capability the GLS has a greater minimum ground clearance than the Navigator L (10.1 vs. 9.6 inches), allowing the GLS to travel over rougher terrain without being stopped or damaged. The GLS Off-Road Package’s minimum ground clearance is 1.7 inches higher than on the Navigator L (11.3 vs. 9.6 inches).

The Mercedes GLS may be more efficient, handle and accelerate better because it weighs about 250 to 350 pounds less than the Lincoln Navigator L.

The GLS 450 is 1 foot, 4.9 inches shorter than the Navigator L, making the GLS easier to handle, maneuver and park in tight spaces.

Unibody construction lowers the GLS’ center of gravity significantly without reducing ground clearance. This contributes to better on the road handling and better off-road performance and stability. In addition, unibody construction makes the chassis stiffer, improving handling and reducing squeaks and rattles. The Navigator L uses body-on-frame design instead.

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 Navigator L’s cruise control switches are unlit, making them difficult to find at night and operate safely.

Manual rear side window sunshades are available in the GLS to help block heat and glare for the rear passengers. The Navigator L doesn’t offer rear side window sunshades.

When the GLS is put in reverse, the passenger rearview mirror tilts from its original position. This gives the driver a better view of the curb during parallel parking maneuvers. Shifting out of reverse puts the mirror into its original position. The Navigator L’s mirror doesn’t automatically adjust for backing.

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. Lincoln doesn’t offer heated seats in the third row of the Navigator L.

Optional air conditioned the front and second row seats keep the GLS’ passengers comfortable and take the sting out of hot leather in summer. The Navigator L doesn’t offer air-conditioned seats for the second row.

Both the GLS and the Navigator L offer optional massaging front seats. The GLS also offers optional massaging second row seats in order to maximize comfort and eliminate fatigue on long trips. Massaging second row seats aren’t available in the Navigator L.

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