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 Cayenne doesn’t offer pre-crash pretensioners.

Both the Q5 and Cayenne 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 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.

Both the Q5 and the Cayenne 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 lane departure warning 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 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 Cayenne has not been tested, yet.

Warranty

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 Q5’s warranty.

Reliability

The Audi Q5’s engine uses a cast iron block for durability, while the Cayenne’s engines use 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 48 points higher than the Cayenne.

From surveys of all its subscribers, Consumer Reports’ December 2018 Auto Issue reports that Audi vehicles are more reliable than Porsche vehicles. Consumer Reports ranks Audi 4 places higher in reliability than Porsche.

Fuel Economy and Range

On the EPA test cycle the Q5 Auto gets better fuel mileage than the Cayenne with its standard engine (22 city/27 hwy vs. 19 city/23 hwy).

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

Transmission

The Q5 offers a standard sequential manual gearbox (SMG). With no clutch pedal to worry about and a fully automatic mode, an SMG is much more efficient than a conventional automatic but just as easy to drive. The Cayenne doesn’t offer an SMG or a conventional manual transmission.

Suspension and Handling

For better maneuverability, the Q5’s turning circle is 1.3 feet tighter than the Cayenne’s (38.4 feet vs. 39.7 feet).

Chassis

The Audi Q5 may be more efficient, handle and accelerate better because it weighs about 350 to 1000 pounds less than the Porsche Cayenne.

The Q5 is 10.1 inches shorter than the Cayenne, making the Q5 easier to handle, maneuver and park in tight spaces.

The design of the Audi Q5 amounts to more than styling. The Q5 has an aerodynamic coefficient of drag of .32 Cd. That is lower than the Cayenne (.34 to .35) and many sports cars. A more efficient exterior helps keep the interior quieter and helps the Q5 get better fuel mileage.

Cargo Capacity

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

Ergonomics

If the windows are left open on the Q5 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 can only operate the windows from inside the vehicle, with the ignition on.

Heated windshield washer nozzles are standard on the Q5 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.

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 Cayenne doesn’t offer extendable visors.

Recommendations

Consumer Reports® recommends the Audi Q5, based on reliability, safety and performance.

The Audi Q5 outsold the Porsche Cayenne by almost seven to one during the 2018 model year.
