Safety

The Allroad’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 Allroad has a standard Audi Backguard System, which use a specially designed headrest to protect the driver and front passenger from whiplash. During a rear-end collision, the Audi Backguard System moves the headrests forward to prevent neck and spine injuries. At the same time the pretensioning seatbelts fire, removing slack from the belts. The QX50 doesn’t offer a whiplash protection system.

The Allroad has standard Secondary Collision Brake Assist, 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.

To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the Allroad. But it costs extra on the QX50.

Both the Allroad and the QX50 have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger 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, rearview cameras, available lane departure warning systems, blind spot warning systems, around view monitors and rear cross-path warning.

For its top level performance in all IIHS frontal, side, rear impact and roof-crush tests, and its standard front crash prevention system, the Insurance Institute for Highway Safety grants the Allroad the rating of “Top Pick” for 2017, a rating granted to only 139 vehicles tested by the IIHS. The QX50 has not been tested, yet.

Warranty

The Allroad’s corrosion warranty is 5 years longer than the QX50’s (12 vs. 7 years).

There are over 42 percent more Audi dealers than there are Infiniti dealers, which makes it easier should you ever need service under the Allroad’s warranty.

Reliability

The Audi Allroad’s engine uses a cast iron block for durability, while the QX50’s engine uses an aluminum block. Aluminum engine blocks are much more prone to warp and crack at high temperatures than cast iron.

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

A reliable vehicle saves its owner time, money and trouble. Nobody wants to be stranded or have to be without a vehicle while it’s being repaired. Consumer Reports rates the Allroad’s reliability 30 points higher than the QX50.

As tested in Motor Trend the Audi Allroad is faster than the Infiniti QX50:

Fuel Economy and Range

In heavy traffic or at stoplights the Allroad’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.

To lower fuel costs and make buying fuel easier, the Audi Allroad uses regular unleaded gasoline (premium recommended for maximum performance). The QX50 requires premium, which can cost 20 to 55 cents more per gallon.

Transmission

The Allroad’s launch control uses engine electronics to hold engine RPM’s precisely in order to provide the most stable and rapid acceleration possible, using all of the available traction. The QX50 doesn’t offer launch control.

Brakes and Stopping

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

Tires and Wheels

For better traction, the Allroad has larger tires than the QX50 (245/45R18 vs. 235/55R19).

The Allroad’s tires provide better handling because they have a lower 45 series profile (height to width ratio) that provides a stiffer sidewall than the QX50’s standard 55 series tires.

The Allroad 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 Allroad 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 Allroad 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. The QX50’s suspension doesn’t offer adjustable shock absorbers.

The Allroad Premium Plus executes Motor Trend’s “Figure-Eight” maneuver quicker than the QX50 Essential AWD (26.3 seconds @ .69 average G’s vs. 26.9 seconds @ .64 average G’s).

Chassis

The Allroad is 7.3 inches shorter in height than the QX50, making the Allroad much easier to wash and garage and drive (lower center of gravity).

Servicing Ease

The engine in the Allroad 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

The power windows standard on both the Allroad and the QX50 have locks to prevent small children from operating them. When the lock on the Allroad 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 Allroad the driver can close them all at the outside door handle. On a hot day the driver can also lower the windows the same way. The driver of the QX50 can only close the windows from inside the vehicle, with the ignition on.

The Allroad’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 nozzles are standard on the Allroad 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 Allroad’s standard outside mirrors include heating elements to clear off the mirrors for better visibility. Infiniti only offers heated mirrors on the QX50 Essential.

The Allroad offers optional automatic dimming rear and side view mirrors which 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 Allroad has standard heated front seats. Heated front seats cost extra on the QX50, and are only available on the QX50 Luxe/Essential. The Allroad Premium Plus/Prestige also offers optional heated rear seats to keep those passengers extremely comfortable in the winter. Heated rear seats aren’t available in the QX50.

Standard smartphone integration for the Allroad allows the driver and passengers access to select programs on their smartphones, including reading text messages aloud, playing internet radio stations, searching the internet and other connected activities without taking their eyes off the road or their hands from the wheel. The QX50 doesn’t offer factory integrated smartphone program access.
