Safety

The Q5’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The QX30 doesn’t offer pre-crash pretensioners.

Both the Q5 and QX30 have child safety locks to prevent children from opening the rear doors. The Q5 has power child safety locks, allowing the driver to activate and deactivate them from the driver's seat and to know when they're engaged. The QX30’s child locks have to be individually engaged at each rear door with a manual switch. The driver can’t know the status of the locks without opening the doors and checking them.

The Q5 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 QX30 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 Q5. But it costs extra on the QX30.

To help make backing safer, the Q5’s optional cross-path warning system uses wide-angle radar in the rear bumper to alert the driver to vehicles approaching from the side, helping the driver avoid collisions. The QX30 doesn’t offer a cross-path warning system.

Both the Q5 and the QX30 have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, 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 lane departure warning systems, blind spot warning systems and around view monitors.

The Audi Q5 weighs 570 to 760 pounds more than the Infiniti QX30. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.

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 Q5 the rating of “Top Pick” for 2017, a rating granted to only 139 vehicles tested by the IIHS. The QX30 has not been tested, yet.

Warranty

The Q5’s corrosion warranty is 5 years longer than the QX30’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 Q5’s warranty.

Reliability

The Audi Q5’s engine uses a cast iron block for durability, while the QX30’s engine uses an aluminum block. Aluminum engine blocks are much more prone to warp and crack at high temperatures than cast iron.

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 Q5’s reliability 22 points higher than the QX30.

Engine

The Q5’s 2.0 turbo 4 cyl. produces 40 more horsepower (248 vs. 208) and 15 lbs.-ft. more torque (273 vs. 258) than the QX30’s 2.0 turbo 4 cyl.

Fuel Economy and Range

Regenerative brakes improve the Q5’s fuel efficiency by converting inertia back into energy instead of wasting it. The QX30 doesn’t offer a regenerative braking system.

To lower fuel costs and make buying fuel easier, the Audi Q5 uses regular unleaded gasoline (premium recommended for maximum performance). The QX30 requires premium, which can cost 20 to 55 cents more per gallon.

The Q5 has 5.3 gallons more fuel capacity than the QX30 FWD’s standard fuel tank (18.5 vs. 13.2 gallons), for longer range between fill-ups. The Q5 has 3.7 gallons more fuel capacity than the QX30 AWD’s standard fuel tank (18.5 vs. 14.8 gallons).

Transmission

The Q5’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 QX30 doesn’t offer launch control.

Brakes and Stopping

For better stopping power the Q5’s brake rotors are larger than those on the QX30:

Car and Driver

Tires and Wheels

For better traction, the Q5’s optional tires are larger than the largest tires available on the QX30 (255/45R20 vs. 235/50R18).

For better ride, handling and brake cooling the Q5 offers optional 20-inch wheels. The QX30’s largest wheels are only 19-inches.

Suspension and Handling

For a smoother ride and more stable handling, the Q5’s wheelbase is 4.7 inches longer than on the QX30 (111 inches vs. 106.3 inches).

For better handling and stability, the track (width between the wheels) on the Q5 is 1.8 inches wider in the front and 1.4 inches wider in the rear than the average track on the QX30.

For greater off-road capability the Q5 has a greater minimum ground clearance than the QX30 (8.2 vs. 8 inches), allowing the Q5 to travel over rougher terrain without being stopped or damaged.

Passenger Space

The Q5 has 3.3 inches more front headroom, 2.9 inches more front shoulder room, 1.8 inches more rear headroom, 4.3 inches more rear legroom and 3.4 inches more rear shoulder room than the QX30.

For enhanced passenger comfort on long trips the Q5’s rear seats recline. The QX30’s rear seats don’t recline.

Cargo Capacity

The Q5 has a much larger cargo volume with its rear seat up than the QX30 with its rear seat up (25.1 vs. 19.2 cubic feet). The Q5 has a much larger cargo volume with its rear seat folded than the QX30 with its rear seat folded (53.1 vs. 34 cubic feet).

Pressing a switch automatically lowers the Q5’s rear seats, to make changing between passengers and cargo easier. The QX30 doesn’t offer automatic folding seats.

To make loading and unloading groceries and cargo easier when your hands are full, the Q5’s power liftgate can be opened or closed just by kicking your foot under the back bumper, leaving your hands completely free. The QX30 doesn’t offer a power or hands-free opening liftgate.

Towing

The Q5 has a 4400 lbs. towing capacity. The QX30 has no towing capacity.

Servicing Ease

The Q5 uses gas struts to support the hood for easier service access. The QX30 uses a prop rod to support its heavy hood. It takes two hands to open the hood and set the prop rod, the prop rod gets in the way during maintenance and service, and the prop rod could be knocked out, causing the heavy hood to fall on the person maintaining or servicing the car.

The engine in the Q5 is mounted longitudinally (North-South), instead of sideways, as in the QX30. This makes it easier to service and maintain, because the accessory belts are in front.

Ergonomics

The Q5 Prestige has a standard heads-up display that projects speed 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 QX30 doesn’t offer a heads-up display.

The power windows standard on both the Q5 and the QX30 have locks to prevent small children from operating them. When the lock on the Q5 is engaged the driver can still operate all of the windows, for instance to close one opened by a child. The QX30 prevents the driver from operating the other windows just as it does the other passengers.

The Q5’s front and rear power windows all open or close fully with one touch of the switches, making it more convenient at drive-up windows and toll booths, or when talking with someone outside the car. The QX30’s rear power window switches have to be held the entire time to open or close them fully.

The Q5’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 QX30’s standard manually variable intermittent wipers have to be constantly adjusted.

To shield the driver and front passenger’s vision over a larger portion of the windshield and side windows, the Q5 has standard extendable sun visors. The QX30 doesn’t offer extendable visors.

The Q5 has standard heated front seats. Heated front seats are only available on the QX30 Luxe/Sport/Essential. The Q5 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 QX30.

Optional air-conditioned seats in the Q5 Premium Plus/Prestige keep the driver and front passenger comfortable and take the sting out of hot seats in summer. The QX30 doesn’t offer air-conditioned seats.

On extremely cold winter days, the Q5 Premium Plus/Prestige’s optional heated steering wheel provides comfort, allowing the driver to steer safely and comfortably before the vehicle heater warms up. The QX30 doesn’t offer a heated steering wheel.

To quickly and conveniently keep personal devices charged without cables tangling and wearing out, the Audi Q5 Premium Plus/Prestige has a standard wireless phone charging system (Qi) in the center console. The QX30 doesn’t offer wireless personal charging.
