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 Infiniti QX60 doesn’t offer pretensioners for the middle seat belts.

To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the GLS. But it costs extra on the QX60.

When descending a steep, off-road slope, the GLS’ standard Downhill Speed Regulation allows you to creep down safely. The QX60 doesn’t offer Downhill Speed Regulation.

The GLS’ 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 QX60 doesn’t offer a driver alert monitor.

Both the GLS and the QX60 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 and available lane departure warning systems.

The Mercedes GLS weighs 1149 to 1312 pounds more than the Infiniti QX60. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.

There are over 79 percent more Mercedes dealers than there are Infiniti dealers, which makes it much easier should you ever need service under the GLS’ warranty.

J.D. Power and Associates’ 2019 Initial Quality Study of new car owners surveyed provide the statistics that show that Mercedes vehicles are better in initial quality than Infiniti vehicles. J.D. Power ranks Mercedes 12th in initial quality. With 7 more problems per 100 vehicles, Infiniti is ranked 19th.

Regenerative brakes improve the GLS’ fuel efficiency by converting inertia back into energy instead of wasting it. The QX60 doesn’t offer a regenerative braking system.

In heavy traffic or at stoplights the GLS’ engine automatically turns off when the vehicle is stopped, saving fuel and reducing pollution. The engine is automatically restarted when the driver gets ready to move again. (Start/Stop isn’t accounted in present EPA fuel mileage tests.) The QX60 doesn’t offer an automatic engine start/stop system.

The GLS has 4.3 gallons more fuel capacity than the QX60 (23.8 vs. 19.5 gallons), for longer range between fill-ups.

In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the Mercedes GLS higher (6 out of 10) than the Infiniti QX60 (5). This means the GLS produces up to 6.9 pounds less smog-producing pollutants than the QX60 every 15,000 miles.

For better traction, the GLS has larger tires than the QX60 (255/50R19 vs. 235/65R18).

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 QX60’s standard 65 series tires. The GLS’ tires are lower profile than the QX60 Luxe’s optional 55 series tires.

For better ride, handling and brake cooling the GLS has standard 19-inch wheels. Smaller 18-inch wheels are standard on the QX60. The GLS’ optional 23-inch wheels are larger than the 20-inch wheels optional on the QX60 Luxe.

The front and rear suspension of the GLS uses air springs for a smoother, controlled ride than the QX60, 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. Infiniti doesn’t offer an active suspension on the QX60.

The GLS has a standard driver-adjustable suspension system. It allows the driver to choose between an extra-supple ride, reducing fatigue on long trips, or a sport setting, which allows maximum control for tricky roads or off-road. The QX60’s suspension doesn’t offer adjustable shock absorbers.

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 QX60 doesn’t offer a load leveling suspension.

The GLS’ 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 QX60 doesn’t offer drift compensation steering.

For a smoother ride and more stable handling, the GLS’ wheelbase is 9.2 inches longer than on the QX60 (123.4 inches vs. 114.2 inches).

For greater off-road capability the GLS has a 3.6 inches greater minimum ground clearance than the QX60 (10.1 vs. 6.5 inches), allowing the GLS to travel over rougher terrain without being stopped or damaged. The GLS Off-Road Package’s minimum ground clearance is 4.8 inches higher than on the QX60 (11.3 vs. 6.5 inches).

The engine in the GLS is mounted longitudinally (North-South), instead of sideways, as in the QX60. This makes it easier to service and maintain, because there are no rear spark plugs and the accessory belts are in front.

Unlike the driver-only memory system in the QX60 Luxe, 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 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 QX60 doesn’t offer a heads-up display.

The GLS’ power parking brake sets with one touch and releases with one touch or automatically. The QX60’s parking brake has to released manually.

The power windows standard on both the GLS and the QX60 have locks to prevent small children from operating them. When the lock on the GLS is engaged the driver can still operate all of the windows, for instance to close one opened by a child. The QX60 prevents the driver from operating the other windows just as it does the other passengers.

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 QX60’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 QX60 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.

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. Infiniti doesn’t offer heated seats in the third row of the QX60.

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 QX60 doesn’t offer air-conditioned seats for the second row.

The GLS offers optional massaging front and second row seats, which keep the driver and middle row passengers. Massaging seats aren’t available in the QX60.

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 for the rear passengers. The QX60 doesn’t offer wireless personal charging.

The GLS’ Active Parking Assist can parallel park or back into a parking spot by itself, starting, stopping and changing direction automatically. The QX60 doesn’t offer an automated parking system.
