Virtual Adviser's™ opinion
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 diesel engine choice they offer. Both the engines are Audi-engineered . The first one has a 8-cylinder, 32-valves 385hp unit, while the other one gets its power and torque from a 8-cylinder, 32-valves 340hp one.
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, if we'd like to consider vehicle mass in this context too, which we definitely should, Audi Q7 offers a considerable difference of 10% 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, when all the models are taken into account. 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 Cayenne rank it on average as 3.0 out of 5, exactly the same as the other one.
Performance & Fuel economyPorsche is a bit more agile, reaching 100km/h in 0.7 seconds less than its competitor. In addition to that it accelerates all the way to 252 kilometers per hour, 12km/h more than the other car. When it comes to fuel economy an obvious choice would be Audi Q7, averaging around 0 liters of fuel per 100 kilometers (INF mpg), in combined cycle. That's INF% difference compared to Cayenne!
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. It does come at a cost though, and that's the fuel consumption... All together, there's not much more to say, in this case I wouldn't even consider anything but 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.
