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 petrol engine choice they offer. The first one has a Porsche-engineered powertrain under the hood, a 8-cylinder, 32-valves 340hp unit, while the other one gets its power and torque from a 8-cylinder, 32-valves 350hp engine designed by Volkswagen.

The fact that the Audi got tested by the European New Car Assessment Programme (Euro NCAP), while the other contender didn't, offers a slight advantage, as the 4-star rating is better than none. Still, apart from the official crash test results there are other things we need to be aware of. Both vehicles belong to the suv segment, which is generally a very good thing safety-wise, but that fact doesn't break the tie between the two cars. On the other hand, taking kerb weight as an important factor into account, Audi Q7 offers a marginal difference of 1% more metal.

I don't like generalizing things when it comes to reliability, although it does seem that Audi does have a slight advantage, at least on all of the models level. These are the results of an independent reasearch, while our visitors describe reliability of Porsche with an average rating of 4.0, and models under the Audi badge with 4.2 out of 5. Independent research findings rank Cayenne as average reliability-wise, and Q7 is more or less at the same level.That apart, owners of different cars powered by the same engine as Cayenne rank it on average as 4.5, while the one under the competitor's bonnet gets 4.9 out of 5.

Porsche is a bit more agile, reaching 100km/h in 0.6 seconds less than its competitor. Still, it lacks the power to win the top speed competition, topping at 242 kilometers per hour, 2km/h less than the other car. When it comes to fuel economy an obvious choice would be Audi Q7, averaging around 13.3 liters of fuel per 100 kilometers (21 mpg), in combined cycle. That's 19% 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, Audi Q7 beats the other contender by far, making it the best choice without even considering other things. When it comes to performance, both vehicles provide similar experience, so I wouldn't point any of them out. Audi Q7 is in a different dimension economy-wise, and many people will find that crucial. All together, there's not much more to say, in this case I wouldn't even consider anything but Audi. Anyway, that's the most objective conclusion I could've came up with and it's based solely on the information found on this website. Aspects such as design, practicality, brand value and driving experience are there for you to measure them out.
