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. Both the engines are Volkswagen-engineered . The first one has a 6-cylinder, 24-valves 300hp unit, while the other one gets its power and torque from a 6-cylinder, 24-valves 280hp one.

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 it doesn't do much to help us decide between the two. On the other hand, if we'd like to consider vehicle mass in this context too, which we definitely should, Audi Q7 offers a considerable difference of 11% more metal.

Manufacturers have been building their reliability reputation for decades now and, generally speaking, it appears 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 3.9, 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 4.7, while the one under the competitor's bonnet gets 5.0 out of 5.

Porsche is undoubtly more agile, reaching 100km/h in 1 seconds less than its competitor. In addition to that it accelerates all the way to 230 kilometers per hour, 5km/h more than the other car. When it comes to fuel economy the winner has to be Cayenne, averaging around 11.2 liters of fuel per 100 kilometers (25 mpg), in combined cycle. We can't ignore that 8% difference compared to Audi Q7.

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. From there things take a different direction, with Porsche outracing its opponent in any situation possible, making it better choice for boy racers. To make things even better, it consumps less fuel! At the end, as much as I'd like to give you a winner here, it's simply a pure tie if you ask me. 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.
