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. Moving further on, let's take a closer look at some additional safety-related facts. 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, when it comes to weight, a factor that most people underestimate, Audi Q7 offers a considerable difference of 11% more metal.

I don't like generalizing things when it comes to reliability, although it does seem that Audi does have a slight advantage, when all the models are taken into account. That's the official data, 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. Some independent research have also placed 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. 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.
