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 Ford Expedition 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 Expedition 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 Expedition.

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 Expedition uses a body-on-frame design, which has no frame members above the floor of the vehicle.

Both the GLS and the Expedition have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, blind spot warning systems, rearview cameras, rear cross-path warning, driver alert monitors and available lane departure warning systems.

In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the Mercedes GLS higher (6 out of 10) than the Ford Expedition (5). This means the GLS produces up to 6.9 pounds less smog-producing pollutants than the Expedition every 15,000 miles.

The GLS has 4ETS, a true four-wheel-drive system, which uses a four-wheel traction control system to redirect engine power to the axle and wheel that still has traction to keep the GLS moving if even only one wheel still has traction. The Expedition doesn’t offer a true four-wheel drive system; it could get stuck while one or more wheels still have traction.

The GLS’ tires provide better handling because they have a lower 50 series profile (height to width ratio) that provides a stiffer sidewall than the Expedition’s standard 65 series tires.

For better ride, handling and brake cooling the GLS has standard 19-inch wheels. Smaller 18-inch wheels are standard on the Expedition. The GLS’ optional 23-inch wheels are larger than the 22-inch wheels optional on the Expedition.

The front and rear suspension of the GLS uses air springs for a smoother, controlled ride than the Expedition, 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. Ford doesn’t offer an active suspension on the Expedition.

The GLS 450 handles at .87 G’s, while the Expedition XLT 4x4 pulls only .76 G’s of cornering force in a Motor Trend skidpad test.

The GLS 450 executes Motor Trend’s “Figure Eight” maneuver 1.2 seconds quicker than the Expedition XLT 4x4 (26.4 seconds @ .7 average G’s vs. 27.6 seconds @ .62 average G’s).

For better maneuverability, the GLS’ turning circle is 1.6 feet tighter than the Expedition’s (39.4 feet vs. 41 feet).

For greater off-road capability the GLS has a greater minimum ground clearance than the Expedition (10.1 vs. 9.8 inches), allowing the GLS to travel over rougher terrain without being stopped or damaged. The GLS Off-Road Package’s minimum ground clearance is 1.5 inches higher than on the Expedition (11.3 vs. 9.8 inches).

The GLS 450 is 5 inches shorter than the Expedition, 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 Expedition uses body-on-frame design instead.

Unlike the driver-only memory system optional at extra cost in the Expedition, the GLS has standard driver and passenger memory, so that when drivers switch, the memory setting adjusts the driver’s seat, steering wheel position, suspension setting, power steering assist, outside mirror angle, climate settings and radio stations and the front passenger seat also adjusts to the new passenger’s preset preferences.

The GLS’ standard easy entry system raises the steering wheel and glides the driver’s seat back, making it easier for the driver to get in and out. An easy entry system costs extra on the Expedition.

The GLS offers an optional heads-up display that projects speed and navigation instruction readouts in front of the driver’s line of sight, allowing drivers to view information without diverting their eyes from the road. The Expedition doesn’t offer a heads-up display.

The GLS’ front and rear power windows all open or close fully with one touch of the switches, making it more convenient at drive-up windows and toll booths, or when talking with someone outside the car. The Expedition’s standard rear power window switches have to be held the entire time to open or close them fully.

The GLS’ rain-sensitive wipers adjust their speed and turn on and off automatically based on the amount of rainfall on the windshield. This allows the driver to concentrate on driving without constantly adjusting the wipers. The Expedition’s standard intermittent wipers change speed with vehicle speed, but can’t turn on and off or change speed based on changing rainfall.

To help drivers avoid possible obstacles, the GLS has standard cornering lights to illuminate around corners when the turn signals are activated. The Expedition doesn’t offer cornering lights. The GLS also has standard adaptive headlights to illuminate around corners automatically by reading vehicle speed and steering wheel angle.

Manual rear side window sunshades are available in the GLS to help block heat and glare for the rear passengers. The Expedition 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 Expedition’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. Ford doesn’t offer heated seats in the third row of the Expedition.

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 Expedition doesn’t offer air-conditioned seats for the second row.

Both the GLS and the Expedition offer available 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 Expedition.

The GLS has a standard dual zone air conditioning allows the driver and front passenger to choose two completely different temperatures so people with different temperature preferences won’t have to compromise. This makes both the driver and front passenger as comfortable as possible. Dual zone air conditioning costs extra on the Expedition.

To quickly and conveniently keep personal devices charged without cables tangling and wearing out, the Mercedes GLS has a standard wireless phone charging system (Qi) in the center console and one for the rear passengers. Wireless charging costs extra on the Expedition.

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

According to The Car Book by Jack Gillis, the GLS is less expensive to operate than the Expedition because it costs $36 less to do the manufacturer’s suggested maintenance for 50,000 miles. Typical repairs cost much less on the GLS than the Expedition, including $347 less for a timing belt/chain.
