Safety

The QX30 has standard Forward Emergency Braking, which use forward mounted sensors to warn the driver of a possible collision ahead. If the driver doesn’t react and the system determines a collision is imminent, it automatically applies the brakes at full-force in order to reduce the force of the crash or avoid it altogether. The Q3 doesn't offer collision warning or crash mitigation brakes.

The QX30 Sport/Essential’s optional lane departure warning system alerts a temporarily inattentive driver when the vehicle begins to leave its lane. The Q3 doesn’t offer a lane departure warning system.

The QX30 (except Pure) offers an optional Around View® Monitor to allow the driver to see objects all around the vehicle on a screen. The Q3 only offers a rear monitor and front and rear parking sensors that beep or flash a light. That doesn’t help with obstacles to the sides.

The QX30 (except Pure) offers optional InTouch Services™, which uses a global positioning satellite (GPS) receiver and a cellular system to get turn-by-turn driving directions, remotely unlock your doors if you lock your keys in, help track down your vehicle if it’s stolen or send emergency personnel to the scene if any airbags deploy. The Q3 doesn’t offer a GPS response system, only a navigation computer with no live response for emergencies, so if you’re involved in an accident and you’re incapacitated help may not come as quickly.

Both the QX30 and the Q3 have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front and rear seatbelt pretensioners, front wheel drive, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights, rearview cameras and available all wheel drive.

Warranty

The QX30 comes with a full 4-year/60,000-mile basic warranty, which covers the entire truck and includes 24-hour roadside assistance. The Q3’s 4-year/50,000-mile basic warranty expires 10,000 miles sooner.

Infiniti’s powertrain warranty covers the QX30 2 years and 20,000 miles longer than Audi covers the Q3. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 6 years or 70,000 miles. Coverage on the Q3 ends after only 4 years or 50,000 miles.

Reliability

J.D. Power and Associates’ 2018 Initial Quality Study of new car owners surveyed provide the statistics that show that Infiniti vehicles are better in initial quality than Audi vehicles. J.D. Power ranks Infiniti 14th in initial quality, above the industry average. With 13 more problems per 100 vehicles, Audi is ranked 25th, below the industry average.

J.D. Power and Associates’ 2018 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that Infiniti vehicles are more reliable than Audi vehicles. J.D. Power ranks Infiniti fourth in reliability, above the industry average. With 21 more problems per 100 vehicles, Audi is ranked 13th.

From surveys of all its subscribers, Consumer Reports’ December 2018 Auto Issue reports that Infiniti vehicles are more reliable than Audi vehicles. Consumer Reports ranks Infiniti 1 place higher in reliability than Audi.

Fuel Economy and Range

On the EPA test cycle the QX30 gets better fuel mileage than the Q3:

In heavy traffic or at stoplights the QX30’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 Q3 doesn’t offer an automatic engine start/stop system.

Transmission

A seven-speed automatic (SMG) is standard on the Infiniti QX30, for better acceleration and lower engine speed on the highway. Only a six-speed automatic is available for the Q3.

The QX30 offers a standard sequential manual gearbox (SMG). With no clutch pedal to worry about and a fully automatic mode, an SMG is much more efficient than a conventional automatic but just as easy to drive. The Q3 doesn’t offer an SMG or a conventional manual transmission.

Brakes and Stopping

For better stopping power the QX30’s brake rotors are larger than those on the Q3:

Car and Driver

Tires and Wheels

For better traction, the QX30 has larger tires than the Q3 (235/50R18 vs. 225/40R19).

Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires standard on the QX30 can be driven up to 50 miles without any air pressure, allowing you to drive to a service station for a repair. The Q3 doesn’t offer run-flat tires.

Suspension and Handling

For a smoother ride and more stable handling, the QX30’s wheelbase is 3.8 inches longer than on the Q3 (106.3 inches vs. 102.5 inches).

For better maneuverability, the QX30 AWD’s turning circle is 2.1 feet tighter than the Q3’s (36.6 feet vs. 38.7 feet). The QX30’s turning circle is 1.4 feet tighter than the Q3’s (37.3 feet vs. 38.7 feet).

For greater off-road capability the QX30 has a 1.3 inches greater minimum ground clearance than the Q3 (8 vs. 6.7 inches), allowing the QX30 to travel over rougher terrain without being stopped or damaged.

Chassis

The Infiniti QX30 may be more efficient, handle and accelerate better because it weighs about 200 to 250 pounds less than the Audi Q3.

As tested by Car and Driver while at idle, the interior of the QX30 Essential AWD is quieter than the Q3 Prestige Quattro (41 vs. 42 dB).

Passenger Space

The QX30 has 1.4 inches more front headroom, 1.3 inches more front legroom, .1 inches more rear headroom and 2.4 inches more rear legroom than the Q3.

Cargo Capacity

The QX30 has a much larger cargo volume than the Q3 with its rear seat up (19.2 vs. 16.7 cubic feet).

A low lift-over cargo hatch design makes loading and unloading the QX30 easier. The QX30’s cargo hatch lift-over height is 28.1 inches, while the Q3’s liftover is 29.8 inches.

Servicing Ease

The QX30 has a maintenance free battery for long life without checking the battery’s water level. The Q3 doesn’t have a maintenance free battery, so the water level in the battery’s cells must be checked often to prevent damage.

J.D. Power and Associates surveys of service recipients show that Infiniti service is better than Audi. J.D. Power ranks Infiniti first in service department satisfaction. With a 5% lower rating, Audi is ranked third.

Ergonomics

When three different drivers share the QX30 Luxe/Sport/Essential, the memory seats and mirrors make it convenient for all three. Each setting activates different, customized memories for the driver and front passenger’s seat positions and outside mirror angle. The Q3 doesn’t offer a memory system.

The QX30 Luxe/Sport/Essential’s standard easy entry system glides the driver’s seat back when the door is unlocked or the ignition is switched off, making it easier for the driver to get in and out. The Q3 doesn’t offer an easy entry system.

If the windows are left open on the QX30 the driver can close them all at the outside door handle. On a hot day the driver can lower the windows from a distance using the keyless remote. The driver of the Q3 can’t use the remote to operate the windows.

While driving with high beams on, sensitive light sensors available for the QX30 Sport/Essential detect other vehicles which could be blinded and automatically switch to low beams. The Q3 doesn’t offer automatic dimming high beams.

To help drivers see further while navigating curves, the QX30 Sport/Essential has standard adaptive headlights to illuminate around corners automatically by reading vehicle speed and steering wheel angle. The Q3 doesn’t offer cornering lights.

When the QX30 Luxe/Sport/Essential is put in reverse, the passenger rearview mirror tilts from its original position. This gives the driver a better view of the curb during parallel parking maneuvers. Shifting out of reverse puts the mirror into its original position. The Q3’s mirror doesn’t automatically adjust for backing.

The QX30 has standard 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 Q3 offers an automatic rear view mirror, but its side mirrors don’t dim.

To keep a safe, consistent following distance, the QX30 Sport/Essential offers an optional Intelligent Cruise Control, which alters the speed of the vehicle without driver intervention. This allows the driver to use cruise control more safely without constantly having to disengage it when approaching slower traffic. The Q3 doesn’t offer an adaptive cruise control.

The QX30 (except Pure/Luxe)’s optional Intelligent Park Assist can parallel park or back into a parking spot by itself, with the driver only controlling speed with the brake pedal. The Q3 doesn’t offer an automated parking system.

Economic Advantages

Insurance will cost less for the QX30 owner. The Car Book by Jack Gillis rates the QX30 with a number “5” insurance rate while the Q3 is rated higher at a number “10” rate.

According to The Car Book by Jack Gillis, the QX30 is less expensive to operate than the Q3 because it costs $252 less to do the manufacturer’s suggested maintenance for 50,000 miles. Typical repairs cost much less on the QX30 than the Q3, including $19 less for front brake pads, $274 less for a starter, $24 less for fuel injection and $362 less for front struts.

Recommendations

Car and Driver performed a comparison test in its September 2016 issue and they ranked the Infiniti QX30 Essential AWD higher than the Audi Q3 Prestige Quattro.
