Safety Comparison

The Q7’s optional pre-crash 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.

Both the Q7 and the Cayenne have standard driver and passenger frontal airbags, front side-impact airbags, side-impact 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).

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

Fuel Economy and Range Comparison

The Q7 has 5.3 gallons more fuel capacity than the Cayenne S E-Hybrid’s standard fuel tank (26.4 vs. 21.1 gallons), for longer range between fill-ups.

Suspension and Handling Comparison

The Q7 Prestige 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).

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.

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 with available tilt-down mirrors 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.

Economic Advantages Comparison

The Q7 will cost the buyer less in the long run because of its superior resale value. The Intellichoice estimates that the Q7 will retain 52.45% to 55.77% of its original price after five years, while the Cayenne only retains 45.18% to 51.49%.

According to The Car Book by Jack Gillis, the Q7 is less expensive to operate than the Cayenne because it costs $63 less to do the manufacturer’s suggested maintenance for 50,000 miles. Typical repairs cost much less on the Q7 than the Cayenne, including $93 less for a water pump, $369 less for an alternator, $119 less for front brake pads and $639 less for a power steering pump.

Intellichoice estimates that five-year ownership costs (depreciation, financing, insurance, fuel, fees, repairs and maintenance) for the Audi Q7 will be $8462 to $43365 less than for the Porsche Cayenne.

Recommendations Comparison

The Audi Q7 outsold the Porsche Cayenne by 14% during 2014.
