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 250hp 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 that fact doesn't break the tie between the two cars. On the other hand, if we'd like to consider vehicle mass in this context too, which we definitely should, Audi Q7 offers a marginal difference of 2% more metal.

Reliability 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 3.9, 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.Above it all, drivers of cars with the same engine as Cayenne rank it on average as 4.3, while the one under the competitor's bonnet gets 5.0 out of 5.

Audi is a bit more agile, reaching 100km/h in 0.8 seconds less than its competitor. In addition to that it accelerates all the way to 225 kilometers per hour, 11km/h more than the other car. When it comes to fuel economy things look pretty much the same for both cars, averaging around 13 liters of fuel per 100 kilometers (22 mpg), in combined cycle.

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. It all continues in the same direction, with Audi outracing its opponent in any situation possible, making it better choice for boy racers. To make things even better, it consumps less fuel! All together, there's not much more to say, in this case I wouldn't even consider anything but Audi. In any case that's my personal view, built upon all the data available to me. What should decide here though is the way you feel about the two vehicles, and I hope you'll find my guidelines useful in the process.
