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 Cayenne Coupe doesn’t offer pre-crash pretensioners.
Both the Q7 and Cayenne Coupe 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 Coupe’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.
Over 200 people are killed each year when backed over by motor vehicles. The Q7 offers an optional backup collision prevention system that uses rear sensors to monitor and automatically apply the brakes to prevent a rear collision. The Cayenne Coupe doesn’t offer backup collision prevention brakes.
Both the Q7 and the Cayenne Coupe have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, height adjustable front shoulder belts, four-wheel antilock brakes, all-wheel drive, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, post-collision automatic braking systems, daytime running lights, rearview cameras, available night vision systems, blind spot warning systems, around view monitors and rear cross-path warning.
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 185 vehicles tested by the IIHS. The Cayenne Coupe has not been tested, yet.
There are over 59 percent more Audi dealers than there are Porsche dealers, which makes it much easier should you ever need service under the Q7’s warranty.
On the EPA test cycle the Q7 45 TFSI gets better fuel mileage than the Cayenne Coupe with its standard engine (19 city/25 hwy vs. 19 city/23 hwy).
In an emergency stopping situation, many drivers don’t press the brakes with enough force to stop the vehicle in the shortest distance. The Q7 has a standard brake assist system to detect emergency braking situations (by how hard and how quickly the brake pedal is pressed) and then automatically apply maximum braking immediately in order to help prevent a collision. The Cayenne Coupe doesn’t offer a brake assist feature.
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 Cayenne Coupe doesn’t offer run-flat tires.
For a smoother ride and more stable handling, the Q7’s wheelbase is 3.9 inches longer than on the Cayenne Coupe (117.9 inches vs. 114 inches).
For greater off-road capability the Q7 has a greater minimum ground clearance than the Cayenne Coupe (8.3 vs. 8.2 inches), allowing the Q7 to travel over rougher terrain without being stopped or damaged.

The Q7 has a standard remote vehicle starting system, so the vehicle can be started from inside the driver's house. This allows the driver to comfortably warm up the engine before going out to the vehicle. The climate system will also automatically heat or cool the interior. The Cayenne Coupe doesn’t offer a remote starting system.
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 lower the windows from a distance using the keyless remote. The driver of the Cayenne Coupe can only operate the windows from inside the vehicle, with the ignition on.
The Q7’s power window, power lock, power mirror and cruise control switches are lit from behind, making them plainly visible and easier to operate at night. The Cayenne Coupe’s cruise control switches are unlit, making them difficult to find at night and operate safely.
To improve rear visibility by keeping the rear window clear, the Q7 has a standard rear wiper. The Cayenne Coupe doesn’t offer a rear wiper.
To shield the driver and front passenger’s vision over a larger portion of the windshield and side windows, the Q7 has standard extendable sun visors. The Cayenne Coupe doesn’t offer extendable visors.
A manual rear sunshade and rear side window sunshades are optional in the Q7 (except Premium) to help block heat and glare for the rear passengers. The Cayenne Coupe doesn’t offer a rear sunshade.
