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. The first one has a Audi-engineered powertrain under the hood, a 8-cylinder, 32-valves 326hp unit, while the other one gets its power and torque from a 6-cylinder, 24-valves 286hp engine designed by BMW.

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. 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. Furthermore, if we'd like to consider vehicle mass in this context too, which we definitely should, Audi Q7 offers a considerable difference of 16% more metal.

I don't like generalizing things when it comes to reliability, although it does seem that both brands display similar results in faults and breakdowns, when all the models are taken into account. These are the official statistics, while our visitors describe reliability of Audi with an average rating of 4.2, and models under the BMW badge with 4.1 out of 5. Some independent research have also placed Q7 50% below average, and X5 is more or less at the same level.We should definitely mention that owners of cars with the same powertrain as Audi Q7 rank it on average as 4.5, while the one under the competitor's bonnet gets 4.3 out of 5.

Audi is a bit more agile, reaching 100km/h in 0.6 seconds less than its competitor. In addition to that it accelerates all the way to 236 kilometers per hour, 1km/h more than the other car. When it comes to fuel economy an obvious choice would be BMW X5, averaging around 8.3 liters of fuel per 100 kilometers (34 mpg), in combined cycle. That's 34% 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. It all continues in the same direction, with Audi being considerably quicker, thus putting more smile on driver's face. It does come at a cost though, and that's the fuel consumption... I believe that, when we take all into account, we have only one winner here - the Audi.
