Safety

For enhanced safety, the front and middle seat shoulder belts of the Audi Q7 have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision and force limiters to limit the pressure the belts will exert on the passengers. The Ford Flex doesn’t offer pretensioners for the middle seat belts.

The Q7’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Flex doesn’t offer pre-crash pretensioners.

Both the Q7 and Flex have child safety locks to prevent children from opening the rear doors. The Q7 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 Flex’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 Q7 has standard Pre Sense City, 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 Flex offers an available collision warning system without the automated brake feature that would prevent or reduce the collision if the driver fails to react.

The Q7 has a standard Secondary Collision Brake Assist, which automatically applies the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The Flex 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.

Over 200 people are killed each year when backed over by motor vehicles. The Q7 offers an optional backup collision prevention system which use rear sensors to monitor and automatically apply the brakes to prevent a rear collision. The Flex doesn’t offer backup collision prevention brakes.

To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the Q7. But it costs extra on the Flex.

When descending a steep, off-road slope, the Q7’s standard Hill Descent Assist allows you to creep down safely. The Flex doesn’t offer Hill Descent Assist.

The Audi Q7 has Daytime Running Lights to help keep it more visible under all conditions. Canadian government studies show that driving with lights during the day reduces accidents by 11% by making vehicles more conspicuous. The Flex doesn’t offer Daytime Running Lights.

A passive infrared night vision system optional on the Q7 Prestige helps the driver to more easily detect people, animals or other objects in front of the vehicle at night. Using an infrared camera to detect heat, the system then displays the image on a monitor in the dashboard. The Flex doesn’t offer a night vision system.

The Q7’s optional lane departure warning system alerts a temporarily inattentive driver when the vehicle begins to leave its lane and gently nudges the vehicle back towards its lane. The Flex doesn’t offer a lane departure warning system.

The Q7 offers an optional Top View Cameras to allow the driver to see objects all around the vehicle on a screen. The Flex only offers a rear monitor and rear parking sensors that beep. That doesn’t help with obstacles to the front or sides.

Both the Q7 and the Flex 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, rearview cameras, available blind spot warning systems and rear cross-path warning.

A significantly tougher test than their original offset frontal crash test, the Insurance Institute for Highway Safety does 40 MPH small overlap frontal offset crash tests. In this test, where only 25% of the total width of the vehicle is struck, results indicate that the Audi Q7 is safer than the Flex:

For its top level performance in all IIHS frontal, side, rear impact and roof-crush tests, and with its optional front crash prevention system, the Insurance Institute for Highway Safety grants the Q7 the rating of “Top Pick” for 2017, a rating granted to only 139 vehicles tested by the IIHS. The Flex was not even a “Top Pick” for 2016.

Warranty

The Q7 comes with a full 4-year/50,000-mile basic warranty, which covers the entire truck and includes 24-hour roadside assistance. The Flex’s 3-year/36,000-mile basic warranty expires 1 year and 14,000 miles sooner.

The Q7’s corrosion warranty is 7 years longer than the Flex’s (12 vs. 5 years).

Reliability

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 Q7’s reliability 11 points higher than the Flex.

J.D. Power and Associates’ 2018 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that Audi vehicles are more reliable than Ford vehicles. J.D. Power ranks Audi 13th in reliability, above the industry average. With 11 more problems per 100 vehicles, Ford is ranked 16th.

From surveys of all its subscribers, Consumer Reports’ December 2018 Auto Issue reports that Audi vehicles are more reliable than Ford vehicles. Consumer Reports ranks Audi 11 places higher in reliability than Ford.

Engine

The Q7 45 TFSI’s standard 2.0 turbo 4 cyl. produces 19 lbs.-ft. more torque (273 vs. 254) than the Flex’s standard 3.5 DOHC V6.

As tested in Car and Driver the Q7 55 TFSI 3.0 supercharged V6 is faster than the Flex Limited 3.5 turbo V6:

In heavy traffic or at stoplights the Q7’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 Flex doesn’t offer an automatic engine start/stop system.

The Q7 has 3.9 gallons more fuel capacity than the Flex (22.5 vs. 18.6 gallons), for longer range between fill-ups.

Transmission

An eight-speed automatic is available on the Audi Q7, for better acceleration and lower engine speed on the highway. Only a six-speed automatic is available for the Flex.

Brakes and Stopping

For better stopping power the Q7’s brake rotors are larger than those on the Flex:

Tires and Wheels

For better traction, the Q7 has larger standard tires than the Flex (255/55R19 vs. 235/60R18). The Q7’s optional tires are larger than the largest tires available on the Flex (285/45R20 vs. 255/45R20).

The Q7’s optional tires provide better handling because they have a lower 40 series profile (height to width ratio) that provides a stiffer sidewall than the Flex’s optional 45 series tires.

For better ride, handling and brake cooling the Q7 2.0T has standard 18-inch wheels. Smaller 17-inch wheels are standard on the Flex SE. The Q7’s optional 21-inch wheels are larger than the 20-inch wheels optional on the Flex.

Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires available on the Q7 can be driven up to 50 miles without any air pressure, allowing you to drive to a service station for a repair. The Flex doesn’t offer run-flat tires.

Suspension and Handling

The Q7 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 Flex’s suspension doesn’t offer adjustable shock absorbers.

For better handling and stability, the track (width between the wheels) on the Q7 is .7 inches wider in the front and 1.2 inches wider in the rear than on the Flex.

The Q7 Prestige handles at .85 G’s, while the Flex SEL AWD pulls only .78 G’s of cornering force in a Car and Driver skidpad test.

Chassis

The design of the Audi Q7 amounts to more than styling. The Q7 has an aerodynamic coefficient of drag of .333 Cd (optional .32 Cd with Air Suspension). That is lower than the Flex (.36) and many sports cars. A more efficient exterior helps keep the interior quieter and helps the Q7 get better fuel mileage.

As tested by Car and Driver while under full throttle, the interior of the Q7 Prestige is quieter than the Flex Limited AWD (70 vs. 73 dB).

Passenger Space

The Q7 has 1.1 inches more front shoulder room and .4 inches more rear shoulder room than the Flex.

Cargo Capacity

To make loading groceries and cargo easier when your hands are full, the Q7’s liftgate can be opened and closed just by waving your foot, leaving your hands completely free. The Flex doesn’t offer a hands-free gesture to open its liftgate, forcing you to put cargo down if your hands are full.

Towing

The Q7’s standard towing capacity is much higher than the Flex’s (4400 vs. 2000 pounds). Maximum trailer towing in the Ford Flex is only 4500 pounds. The Q7 offers up to a 7700 lbs. towing capacity.

Servicing Ease

The engine in the Q7 is mounted longitudinally (North-South), instead of sideways, as in the Flex. This makes it easier to service and maintain, because there are no rear spark plugs and the accessory belts are in front.

J.D. Power and Associates surveys of service recipients show that Audi service is better than Ford. J.D. Power ranks Audi third in service department satisfaction. With a 60% lower rating, Ford is ranked 24th.

Ergonomics

Unlike the driver-only memory system optional at extra cost in the Flex (except SE), the Q7 Prestige 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 Q7 Prestige has a standard heads-up display that projects speed and other key instrumentation readouts in front of the driver’s line of sight, allowing drivers to view information without diverting their eyes from the road. The Flex doesn’t offer a heads-up display.

The Q7’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 Flex’s rear power window switches have to be held the entire time to open or close them fully.

If the windows are left open on the Q7 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 also lower the windows the same way. The driver of the Flex can only operate the windows from inside the vehicle, with the ignition on.

The Q7 has a standard locking fuel door with a remote release located convenient to the driver. A locking fuel door helps prevent vandalism, such as sugar in the tank and fuel theft. The Flex doesn’t offer a locking fuel door.

The Q7’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 Flex SE/SEL’s standard intermittent wipers change speed with vehicle speed, but can’t turn on and off or change speed based on changing rainfall.

In poor weather, headlights can lose their effectiveness as grime builds up on their lenses. This can reduce visibility without the driver realizing. The Q7 offers available headlight washers to keep headlight output high. The Flex doesn’t offer headlight washers.

While driving with high beams on, sensitive light sensors available for the Q7 detect other vehicles which could be blinded and automatically switch to low beams. The Flex doesn’t offer automatic dimming high beams.

To help drivers avoid possible obstacles, the Q7 offers optional cornering lights to illuminate around corners when the turn signals are activated. The Flex doesn’t offer cornering lights. The Q7 also offers optional adaptive headlights to illuminate around corners automatically by reading vehicle speed and steering wheel angle.

To better shield the driver and front passenger’s vision, the Q7 has standard dual-element sun visors that can block glare from two directions simultaneously. The Flex doesn’t offer secondary sun visors.

A manual rear sunshade is optional in the Q7 to help block heat and glare for the rear passengers. The Flex doesn’t offer a rear sunshade.

When the Q7 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 Flex’s mirror doesn’t automatically adjust for backing.

The Q7 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 Flex has an automatic rear view mirror, but its side mirrors don’t dim.

The Q7 has a standard dual zone air conditioning allows the driver and front passenger to choose two completely different temperatures so people with different temperature preferences won’t have to compromise. This makes both the driver and front passenger as comfortable as possible. Dual zone air conditioning is only available on the Flex SEL/Limited.

Economic Advantages

According to The Car Book by Jack Gillis, the Q7 is less expensive to operate than the Flex because typical repairs cost less on the Q7 than the Flex, including $139 less for a water pump and $59 less for a power steering pump.

Recommendations

Consumer Reports® recommends the Audi Q7, based on reliability, safety and performance. The Ford Flex isn't recommended.

The Q7 was chosen as one of Car and Driver’s “Top Five/10Best Trucks” for 2 of the last 2 years. The Flex has never been a Car and Driver “Top Five/10Best Truck” pick.

The Audi Q7 outsold the Ford Flex by 78% during the 2018 model year.
