The QX50 has a standard easy tire fill system. When inflating the tires, the vehicle’s integrated tire pressure sensors keep track of the pressure as the tires fill and tell the driver when the tires are inflated to the proper pressure. The GLE doesn’t offer vehicle monitored tire inflation.

Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires standard on the QX50 can be driven up to 50 miles without any air pressure, allowing you to drive to a service station for a repair. The GLE doesn’t offer run-flat tires.

The Infiniti QX50 may be more efficient, handle and accelerate better because it weighs about 900 pounds less than the Mercedes GLE.

The QX50 is 9.6 inches shorter than the GLE, making the QX50 easier to handle, maneuver and park in tight spaces.

The QX50 uses computer-generated active noise cancellation to help remove annoying noise and vibration from the passenger compartment, especially at low frequencies. The GLE doesn’t offer active noise cancellation.

To improve rear visibility by keeping the rear window clear, the QX50 has a standard rear fixed intermittent wiper with a full on position. The rear wiper standard on the GLE only has an intermittent setting, so in a hard rain visibility isn’t as good.
