Two significantly similar cars, no doubt about that. Still, each one has something different to offer. Having both cars powered by diesel engines and utilizing the 5-door suv body style within the same 'SUV' segment, the only major difference here really is their wheel drive configuration (front for the Audi and 4 x 4 in the case of the Infiniti). The first one has a Volkswagen-engineered powertrain under the hood, a 4-cylinder, 16-valves 143hp unit, while the other one gets its power and torque from a 6-cylinder, 24-valves 240hp engine designed by Renault.

The fact that the Audi got tested by the European New Car Assessment Programme (Euro NCAP), while the other contender didn't, puts it sky-high safety-wise, in my eyes at least. Still, apart from the official crash test results there are other things we need to be aware of. 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, the Japanese car offers a considerable difference of 14% more metal.

Reliability is not the best thing to consider on the make level, but it is worth mentioning that Infiniti does have a slight advantage, at least on all of the models level. That's the official data, while our visitors describe reliability of Audi with an average rating of 4.2, and models under the Infiniti badge with 4.6 out of 5. Some independent research have also placed Q5 50% below average, and EX those same 50% above the first one. That apart, owners of different cars powered by the same engine as the German car rank it on average as 4.3, while the one under the competitor's bonnet gets 3.1 out of 5.

Infiniti is way more agile, reaching 100km/h in 3.1 seconds less than its competitor. In addition to that it accelerates all the way to 221 kilometers per hour, 29km/h more than the other car. When it comes to fuel economy an obvious choice would be the German car, averaging around 5.7 liters of fuel per 100 kilometers (50 mpg), in combined cycle. That's 49% difference compared to the Japanese car!

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, the German car beats the other contender by far, making it the best choice without even considering other things. From there things take a different direction, with Infiniti outracing its opponent in any situation possible, making it better choice for boy racers. 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. 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. In case you have two minutes to spare I invite you to define your needs, desires and budget and see which car would be chosen by the virtual adviser™, out of 12.000+ vehicles we currently have in our database.
