Safety Comparison

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

For enhanced safety, the front and middle seat shoulder belts of the Audi Q7 are height-adjustable to accommodate a wide variety of driver and passenger heights. A better fit can prevent injuries and the increased comfort also encourages passengers to buckle up. The Porsche Cayenne has only front height-adjustable seat belts.

Both the Q7 and Cayenne 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 Cayenne’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 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. The Cayenne doesn’t offer a whiplash protection system.

The Q7’s optional lane departure warning system alerts a temporarily inattentive driver when the vehicle begins to leave its lane. The Cayenne doesn’t offer a lane departure warning system.

Both the Q7 and the Cayenne have standard driver and passenger frontal airbags, front side-impact airbags, head airbags, front and rear seatbelt pretensioners, height-adjustable front shoulder belts, plastic fuel tanks, four-wheel antilock brakes, all-wheel drive, traction control and electronic stability systems to prevent skidding.

Warranty Comparison

The Q7’s corrosion warranty is 2 years longer than the Cayenne’s (12 vs. 10 years).

Audi pays for scheduled maintenance on the Q7 for 1 year and 5000 miles. Audi will pay for oil changes, tire rotation, lubrication and any other scheduled maintenance. Porsche doesn’t pay scheduled maintenance for the Cayenne.

There are over 30 percent more Audi dealers than there are Porsche dealers, which makes it easier to get service under the Q7’s warranty.

Reliability Comparison

The camshafts in the Q7’s engine are driven by a hardened steel chain, with no maintenance needs. The Cayenne Hybrid 3.6 DOHC V6 hybrid, Cayenne 3.0 DOHC V6 hybrid’s camshafts are driven by a rubber belt that needs periodic replacement. If the Cayenne’s cam drive belt breaks the engine could be severely damaged when the pistons hit the opened valves.

Consumer Reports

Tires and Wheels Comparison

For better traction, the Q7 S line Prestige’s optional tires are larger than the largest tires available on the Cayenne (295/35R21 vs. 265/50R19).

The Q7 S line Prestige’s optional tires provide better handling because they have a lower 35 series profile (height to width ratio) that provides a stiffer sidewall than the Cayenne’s optional 50 series tires.

Suspension and Handling Comparison

The Q7 has a standard automatic front and rear load leveling suspension to keep ride height level with a heavy load or when towing. The Q7’s height leveling suspension allows the driver to raise ride height for better off-road clearance and then lower it again for easier entering and exiting and better on-road handling. The Cayenne doesn’t offer a load leveling suspension.

For a smoother ride and more stable handling, the Q7’s wheelbase is 4.2 inches longer than on the Cayenne (118.2 inches vs. 114 inches).

Passenger Space Comparison

The Q7 has standard seating for 7 passengers; the Cayenne can only carry 5.

The Q7 has .7 inches more front legroom, .2 inches more front shoulder room, .1 inches more rear headroom, 1.1 inches more rear legroom and 1.4 inches more rear shoulder room than the Cayenne.

Ergonomics Comparison

If the windows are left down on the Q7 the driver can raise them all using the key in the outside lock cylinder; on a hot day the driver can lower the windows. The driver of the Cayenne can only operate the windows from inside the vehicle, with the ignition on.

Heated windshield washer nozzles are standard on the Q7 to prevent washer fluid and nozzles from freezing and help continue to keep the windshield clear in sub-freezing temperatures. The Cayenne doesn’t offer heated windshield washer nozzles.

A manual rear sunshade is optional in the Q7 to help block heat and glare for the rear passengers. The Cayenne 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 Cayenne’s mirror doesn’t automatically adjust for backing.

The Q7’s available GPS navigation system has a real-time traffic update feature that offers alternative routes to automatically bypass traffic problems. (Service available in a limited number of metro areas.) The Cayenne’s available navigation system doesn’t offer real-time traffic updates.
