The GLE’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The QX50 doesn’t offer pre-crash pretensioners.

The GLE offers optional Post-Collision Brake, which automatically apply the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The QX50 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.

When descending a steep, off-road slope, the GLE’s standard Downhill Speed Regulation allows you to creep down safely. The QX50 doesn’t offer Downhill Speed Regulation.

Earlier warning of stopped traffic, traffic signals, dangerous road conditions, weather, or accidents, can keep driver's safer and prevent crashes. The GLE has Car-to-X Communication, a system that seamlessly communicates important warnings to the driver about impending danger, if they're available. The QX50 doesn’t offer a system that can receive automated systems from other vehicles.

Both the GLE and QX50 have rear cross-traffic warning, but the GLE has Active Brake Assist (automatically applies the brakes) to better prevent a collision when backing near traffic. The QX50’s Rear Cross Traffic Alert doesn’t automatically brake.

The GLE’s 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 QX50 doesn’t offer a driver alert monitor.

Both the GLE and the QX50 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, 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, rearview cameras, rear cross-path warning and available lane departure warning systems.

The Mercedes GLE weighs 690 to 1775 pounds more than the Infiniti QX50. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.

The National Highway Traffic Safety Administration does 35 MPH front crash tests on new vehicles. In this test, results indicate that the Mercedes GLE is safer than the Infiniti QX50:

New test not comparable to pre-2011 test results. More stars = Better. Lower test results = Better.

Side impacts caused 23% of all road fatalities in 2018, down from 29% in 2003, when the Insurance Institute for Highway Safety introduced its side barrier test. In order to continue improving vehicle safety, the IIHS has started using a more severe side impact test: 37 MPH (up from 31 MPH), with a 4180-pound barrier (up from 3300 pounds). The results of this newly developed test demonstrates that the Mercedes GLE is safer than the QX50:

	GLE	QX50

The Mercedes GLE (with optional crash prevention) has achieved the Insurance Institute for Highway Safety’s (IIHS) highest rating of “Top Safety Pick Plus” for the 2024 model year. This distinction is based on its exceptional performance in IIHS’ rigorous battery of safety tests. Specifically, it earned a “Good” rating in the latest, more stringent moderate overlap front crash test, a “Good” result in the updated side impact test, and an “Acceptable” score in the revised pedestrian crash prevention test. The QX50 is not even a standard “Top Safety Pick” for 2024.

Warranty

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

Reliability

J.D. Power and Associates’ 2024 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that Mercedes vehicles are more reliable than Infiniti With 1 fewer problems per 100 vehicles in the first three years of ownership, J.D. Power ranks Mercedes higher than Infiniti.

Engine

The GLE 350’s standard 2.0 turbo 4-cylinder hybrid produces 15 lbs.-ft. more torque (295 vs. 280) than the QX50’s 2.0 turbo 4-cylinder. The GLE 450’s standard 3.0 turbo 6-cylinder hybrid produces 107 more horsepower (375 vs. 268) and 89 lbs.-ft. more torque (369 vs. 280) than the QX50’s 2.0 turbo 4-cylinder. The GLE 450e’s standard 2.0 turbo 4-cylinder hybrid produces 113 more horsepower (381 vs. 268) and 199 lbs.-ft. more torque (479 vs. 280) than the QX50’s 2.0 turbo 4-cylinder. The GLE 580’s standard 4.0 turbo V8 hybrid produces 242 more horsepower (510 vs. 268) and 258 lbs.-ft. more torque (538 vs. 280) than the QX50’s 2.0 turbo 4-cylinder.

As tested in Motor Trend the Mercedes GLE is faster than the Infiniti QX50:

	GLE 450	GLE 450e	QX50
Zero to 60 MPH	5.6 sec	5.5 sec	6.9 sec
Quarter Mile	14.2 sec	14 sec	15.4 sec
Speed in 1/4 Mile	97.4 MPH	98.2 MPH	91.6 MPH

Fuel Economy and Range

On the EPA test cycle the GLE 450e running on electricity gets better mileage than the QX50 (57 city/63 hwy MPGe vs. 22 city/28 hwy).

The GLE 450e can travel with zero emissions for 50 miles. The QX50 can’t move without running its internal combustion engine.

Regenerative brakes improve the GLE’s fuel efficiency by converting inertia back into energy instead of wasting it. The QX50 doesn’t offer a regenerative braking system.

In heavy traffic or at stoplights the GLE’s 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. If the conditions warrant or the driver wishes, the system can be manually disabled at any time for the duration of a trip. The QX50 doesn’t offer an automatic engine start/stop system.

The GLE 450e’s standard fuel tank has 1.2 gallons more fuel capacity than the QX50 (17.2 vs. 16 gallons), for longer range between fill-ups. The GLE’s standard fuel tank has 6.5 gallons more fuel capacity than the QX50 (22.5 vs. 16 gallons).

Brakes and Stopping

For better stopping power the GLE’s brake rotors are larger than those on the QX50:

	GLE	QX50
Front Rotors	14.8 inches	13 inches
Rear Rotors	13.6 inches	12.1 inches

The GLE stops much shorter than the QX50:

	GLE	QX50
60 to 0 MPH	115 feet	127 feet	Motor Trend

Tires and Wheels

For better traction, the GLE has larger standard tires than the QX50 (255/50R19 vs. 235/55R19). The GLE 580’s optional tires are larger than the largest tires available on the QX50 (F:285/40R22 & R:325/35R22 vs. 255/45R20).

The GLE’s standard tires provide better handling because they have a lower 50 series profile (height to width ratio) that provides a stiffer sidewall than the QX50’s standard 55 series tires. The GLE 580’s optional 285/40R22 front and 325/35R22 rear tires have a lower 40 series front and 35 series rear profile than the QX50 Sport’s 45 series tires.

For better ride, handling and brake cooling the GLE 580 offers optional 22-inch wheels. The QX50’s largest wheels are only 20-inches.

The GLE 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 QX50; 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

The GLE has standard front and rear gas-charged shocks for better control over choppy roads. The QX50’s suspension doesn’t offer gas-charged shocks.

The GLE 450/580 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 QX50.

The GLE offers an available 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 QX50’s suspension doesn’t offer adjustable shock absorbers.

The GLE has a standard automatic front and rear load leveling suspension to keep ride height level with a heavy load or when towing. The GLE’s 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 QX50 doesn’t offer a load leveling suspension.

The GLE’s 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 QX50 doesn’t offer drift compensation steering.

For a smoother ride and more stable handling, the GLE’s wheelbase is 7.7 inches longer than on the QX50 (117.9 inches vs. 110.2 inches).

For better handling and stability, the track (width between the wheels) on the GLE is 1.2 inches wider in the front and 2.4 inches wider in the rear than the average track on the QX50.

The GLE’s front to rear weight distribution is more even (53.5% to 46.5%) than the QX50’s (58.2% to 41.8%). This gives the GLE more stable handling and braking.

The GLE 450 handles at .83 G’s, while the QX50 pulls only .81 G’s of cornering force in a Motor Trend skidpad test.

For greater off-road capability the GLE Airmatic has a greater minimum ground clearance than the QX50 (9.2 vs. 8.6 inches), allowing the GLE to travel over rougher terrain without being stopped or damaged.

Chassis

The design of the Mercedes GLE amounts to more than styling. The GLE has an aerodynamic coefficient of drag of .29 Cd. That is lower than the QX50 (.32) and many sports cars. A more efficient exterior helps keep the interior quieter and helps the GLE get better fuel mileage.

Passenger Space

The GLE offers optional seating for 7 passengers; the QX50 can only carry 5.

The GLE has .7 inches more front legroom, 1.4 inches more front shoulder room, 2.2 inches more rear legroom and 1.2 inches more rear shoulder room than the QX50.

Cargo Capacity

The GLE has a much larger cargo volume with its rear seat up than the QX50 with its rear seat up (33.3 vs. 31.4 cubic feet). The GLE has a much larger cargo volume with its rear seat folded than the QX50 with its rear seat folded (74.9 vs. 65.1 cubic feet).

The GLE’s cargo area is larger than the QX50’s in every dimension:

	GLE	QX50
Length to seat (2nd/1st)	40”/76.5”	39”/71.7”
Min Width	43.7”	41.5”
Height	35.5”	31.2”

Towing

The GLE has a 7700 lbs. towing capacity. The QX50 has no towing capacity.

Optional Trailer Stability Assist on the GLE uses the Electronic Stability Program sensors to detect trailer sway, then uses individual brakes to counteract any swaying and help keep the tow vehicle and trailer steady. The QX50 doesn’t offer electronic trailer sway control.

Servicing Ease

The engine in the GLE is mounted longitudinally (North-South), instead of sideways, as in the QX50. This makes it easier to service and maintain, because the accessory belts are in front.

Ergonomics

Unlike the driver-only memory seat and mirrors in the QX50 Luxe/Sport, the GLE has standard driver and passenger memory, so that when drivers switch, the memory setting adjusts the driver’s seat, steering wheel position, outside mirror angle and radio stations and the front passenger seat also adjusts to the new passenger’s preset preferences.

The GLE’s instruments include an oil pressure gauge and a temperature gauge - which could save your engine! Often ‘idiot lights’ don’t warn you until damage has been done. The QX50 does not have an oil pressure gauge.

The GLE offers an optional heads-up display that projects speed, tachometer, certain gauge, warning 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 QX50 doesn’t offer a heads-up display.

The power windows standard on both the GLE and the QX50 have locks to prevent small children from operating them. When the lock on the GLE is engaged the driver can still operate all of the windows, for instance to close one opened by a child. The QX50 prevents the driver from operating the other windows just as it does the other passengers.

The GLE’s 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 QX50’s standard intermittent wipers change speed with vehicle speed, but can’t turn on and off or change speed based on changing rainfall.

Heated windshield washer fluid is optional on the GLE to defrost the washer nozzles and quickly clear ice and frost from the windshield without scraping. The QX50 doesn’t offer heated windshield washer fluid.

To help drivers avoid possible obstacles, the GLE offers optional cornering lights to illuminate around corners when the turn signals are activated. The QX50 doesn’t offer cornering lights. The GLE also offers optional adaptive headlights to illuminate around corners automatically by reading vehicle speed and steering wheel angle.

To better shield the driver and front passenger’s vision, the GLE has standard dual-element sun visors that can block glare from two directions simultaneously. The QX50 doesn’t offer secondary sun visors.

The GLE’s standard rear and side view mirrors have an automatic dimming feature. These mirrors can be set to automatically darken quickly when headlights shine on them, keeping following vehicles from blinding or distracting the driver. The QX50 has an automatic rear view mirror, but its side mirrors don’t dim.

The Mercedes GLE has power folding mirrors that offer unparalleled convenience while maneuvering in tight places or parked. With the mirrors folded it’s easier to walk past and help prevent parking damage. The mirrors can be quickly unfolded when the driver is ready to leave. Power folding mirrors are only offered on the QX50 Luxe/Sport.

The GLE has standard heated front seats. Heated front seats are only available on the QX50 Luxe/Sport. The GLE also offers optional heated second row seats to keep those passengers extremely comfortable in the winter. Heated rear seats aren’t available in the QX50.

The GLE offers optional massaging front seats in order to maximize comfort and eliminate fatigue on long trips. Massaging seats aren’t available in the QX50.

The Mercedes GLE has a standard Homelink wireless remote control system for garage door operation and device management, conveniently located on the rear view mirror. Homelink® eliminates the need for separate garage door openers and associated risks of losing, breaking, or having dead batteries. Homelink® is only available on the QX50 Luxe/Sport.

The GLE offers an optional 115-volt a/c outlet on the center console, allowing you to recharge a laptop or run small household appliances without special adapters that can break or get misplaced. The QX50 doesn’t offer a house-current electrical outlet.

The GLE’s Active Parking Assist can parallel park or back into a parking spot by itself, starting, stopping and changing direction automatically. The QX50 doesn’t offer an automated parking system.

Model Availability

The GLE is available in both rear-wheel drive and four-wheel drive configurations. The QX50 doesn’t offer a two-wheel drive configuration.

Economic Advantages

Insurance will cost less for the GLE owner. The Car Book by Jack Gillis rates the GLE with a number “8” insurance rate while the QX50 is rated higher at a number “10” rate.

The GLE will cost the buyer less in the long run because of its superior resale value. The IntelliChoice estimates that the GLE will retain 49.45% to 53.48% of its original price after five years, while the QX50 only retains 46.64% to 48.58%.

According to The Car Book by Jack Gillis, the GLE is less expensive to operate than the QX50 because typical repairs cost much less on the GLE than the QX50, including $441 less for a timing belt/chain and $133 less for a power steering pump.

Recommendations

The Mercedes GLE outsold the Infiniti QX50 by almost six to one during 2023.
