Virtual Adviser's™ opinion
Well, these are two pretty similar cars we have here! It's only details that could potentially make the difference. Not only that they both belong to the suv segment and utilize the same 5-door suv body style, they are even powered by the same Audi-developed diesel engine! There is not much there to point us towards one vehicle or the other. Or is it?
SafetyThe 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. 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, but it doesn't do much to help us decide between the two. On the other hand, taking kerb weight as an important factor into account, Audi Q7 offers a considerable difference of 12% more metal.
ReliabilityReliability is not the best thing to consider on the make level, but it is worth mentioning that Audi does have a slight advantage, at least on all of the models level. 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. The same official information place Cayenne as average reliability-wise, and Q7 is more or less at the same level.Above it all, drivers of cars with the same engine as these two vehicles rank it on average as 4.7 out of 5.
Performance & Fuel economyPorsche is a bit more agile, reaching 100km/h in 0.5 seconds less than its competitor. In addition to that it accelerates all the way to 220 kilometers per hour, 5km/h more than the other car. When it comes to fuel economy the winner has to be Cayenne, averaging around 7.2 liters of fuel per 100 kilometers (39 mpg), in combined cycle. We can't ignore that 17% difference compared to Audi Q7.
Verdict
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 offering somewhat better performance, just enough to call it quicker. To make things even better, it consumps less fuel! No mistake, whatever you decide here, but I'd still go for the 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.
