The GLC’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 GLC has standard NECK-PRO front head restraints, which use a specially designed headrest to protect the driver and front passenger from whiplash. During a rear-end collision, the NECK-PRO front head restraints system moves the headrests forward to prevent neck and spine injuries. The QX50 doesn’t offer a whiplash protection system.

The GLC’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 GLC 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, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, rearview cameras, available all-wheel drive, lane departure warning systems, blind spot warning systems, around view monitors and rear cross-path warning.

For its top level performance in IIHS driver and passenger-side small overlap frontal, moderate overlap frontal, side impact, roof strength and head restraint tests, its standard front crash prevention system, and its headlight’s “Good” rating, the Insurance Institute for Highway Safety grants the GLC its highest rating: “Top Pick Plus” for 2019, a rating granted to only 87 vehicles tested by the IIHS. The QX50 has not been fully tested, yet.

To reliably power the ignition and other systems and to recharge the battery, the GLC has a standard 150-amp alternator. The QX50’s 130-amp alternator isn’t as powerful.

J.D. Power and Associates rated the GLC third among compact premium suvs in their 2019 Initial Quality Study. The QX50 isn’t in the top three in its category.

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.

In heavy traffic or at stoplights the GLC’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. (Start/Stop isn’t accounted in present EPA fuel mileage tests.) The QX50 doesn’t offer an automatic engine start/stop system.

The GLC has 1.4 gallons more fuel capacity than the QX50 (17.4 vs. 16 gallons), for longer range between fill-ups.

The GLC 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 GLC 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 GLC has a standard automatic front and rear load leveling suspension to keep ride height level with a heavy load or when towing. The GLC’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 GLC’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 GLC’s wheelbase is 2.9 inches longer than on the QX50 (113.1 inches vs. 110.2 inches).

The GLC’s front to rear weight distribution is more even (53% to 47%) than the QX50’s (57.9% to 42.1%). This gives the GLC more stable handling and braking.

The front grille of the GLC uses electronically controlled shutters to close off airflow and reduce drag when less engine cooling is needed. This helps improve highway fuel economy. The QX50 doesn’t offer active grille shutters.

The engine in the GLC 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.

Unlike the driver-only memory system optional at extra cost in the QX50 (except Pure/Luxe), the GLC offers an optional passenger memory, so that when drivers switch, the memory setting adjusts the driver’s seat, steering wheel position and outside mirror angle and the front passenger seat also adjusts to the new passenger’s preset preferences.

The GLC’s standard easy entry system raises the steering wheel, making it easier for the driver to get in and out. An easy entry system costs extra on the QX50, and is not available on all models.

The power windows standard on both the GLC and the QX50 have locks to prevent small children from operating them. When the lock on the GLC 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.

If the windows are left open on the GLC the driver can close them all at the outside door handle or from a distance using the remote. On a hot day the driver can lower the windows from a distance using the keyless remote. The driver of the QX50 can only close the windows from inside the vehicle, with the ignition on.

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

Heated windshield washer nozzles are optional on the GLC to prevent washer fluid and nozzles from freezing and help continue to keep the windshield clear in sub-freezing temperatures. The QX50 doesn’t offer heated windshield washer nozzles.

The Insurance Institute for Highway Safety (IIHS) conducts detailed tests on headlights for their range both straight ahead and in curves and to be certain they don’t exceed acceptable amounts of glare to oncoming drivers. The GLC’s available headlights were rated “Good” by the IIHS, while the QX50’s headlights are rated “Acceptable” to “Marginal.”

The GLC’s standard outside mirrors include heating elements to clear off the mirrors for better visibility. Infiniti only offers heated mirrors on the QX50 Essential/Sensory/Autograph.

The GLC’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 offers an automatic rear view mirror, but its side mirrors don’t dim.

The GLC has standard heated front seats. Heated front seats cost extra on the QX50, and aren’t available on the QX50 Pure. The GLC also offers optional heated rear seats to keep those passengers extremely comfortable in the winter. Heated rear seats aren’t available in the QX50.

To quickly and conveniently keep personal devices charged without cables tangling and wearing out, the Mercedes GLC offers an optional wireless phone charging system (Qi) in the center console. The QX50 doesn’t offer wireless personal charging.

The GLC has a 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 GLC’s optional Active Parking Assist can parallel park or back into a parking spot by itself, starting and stopping automatically, with the driver only responsible for switching from reverse to drive. The QX50 doesn’t offer an automated parking system.

According to The Car Book by Jack Gillis, the GLC is less expensive to operate than the QX50 because typical repairs cost much less on the GLC than the QX50, including $424 less for a timing belt/chain and $109 less for a power steering pump.

Consumer Reports® recommends both the Mercedes GLC and the Infiniti QX50, based on reliability, safety and performance.

Motor Trend selected the GLC as their 2017 Sport Utility of the Year. The QX50 has never been chosen.

The Mercedes GLC outsold the Infiniti QX50 by almost four to one during 2019.
