Well, these are two pretty similar cars we have here! It's only details that could potentially make the difference. Considering they both belong to the suv segment and utilize the same 5-door suv body style and the 4 x 4 wheel drive system, it all comes up to the specific hybrid engine choice they offer. The first one has a Volkswagen-engineered powertrain under the hood, a 8-cylinder, 32-valves 680hp unit, while the other one gets its power and torque from a 6-cylinder, 24-valves 374hp engine designed by Audi.

The first thing to look into here would be the results from European New Car Assessment Programme (Euro NCAP) tests performed on the two cars. Good thing is that both vehicles got tested, with the same number of safety stars gained in the process. That aside, let's consider some other aspects which affect safety. Both vehicles belong to the suv segment, which is generally a very good thing safety-wise, still it doesn't help us solve our dilemma, does it? Furthermore, taking kerb weight as an important factor into account, Cayenne offers a marginal difference of 2% more metal.

Reliability is not the best thing to consider on the make level, but it is worth mentioning that Audi does have a slight advantage, all the models observed together. These are the official statistics, while our visitors describe reliability of Porsche with an average rating of 3.7, and models under the Audi badge with 4.2 out of 5. Unfortunatelly, I don't have enough insight that would allow me to comment in more details on the specific models level. We should definitely mention that owners of cars with the same powertrain as Cayenne rank it on average as 3.0 out of 5, exactly the same as the other one.

Porsche is undoubtly more agile, reaching 100km/h in 2.4 seconds less than its competitor. In addition to that it accelerates all the way to 295 kilometers per hour, 65km/h more than the other car. When it comes to fuel economy the winner has to be Audi Q7, averaging around 1.8 liters of fuel per 100 kilometers (157 mpg), in combined cycle. We can't ignore that 106% difference compared to Cayenne.

Audi appears just a bit more reliable, although the difference is truly marginal. The most important thing when deciding between any two vehicles should always be safety, both passive and active. In my opinion, everything taken into account, Cayenne offers slightly better overall protection and takes the lead. It all continues in the same direction, with Porsche being considerably quicker, thus putting more smile on driver's face. It does come at a cost though, and that's the fuel consumption... It's really tough to make a final decision here, but if I'd need to, I'd say Audi. Nevertheless, let's not forget that people have different preferences and needs, so what really counts is your personal feel. I'm only here to help.
