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. The first one has a Mazda-engineered powertrain under the hood, a 4-cylinder, 16-valves 260hp unit, while the other one gets its power and torque from a 6-cylinder, 24-valves 320hp engine designed by Nissan.

The fact that the Infiniti 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. 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, still it doesn't help us solve our dilemma, does it? On the other hand, taking kerb weight as an important factor into account, Infiniti FX offers a considerable difference of 14% more metal.

I don't like generalizing things when it comes to reliability, although it does seem that Mazda does have a slight advantage, at least on all of the models level. That's the official data, while our visitors describe reliability of Mazda with an average rating of 4.4, and models under the Infiniti badge with 4.6 out of 5. Some independent research have also placed CX-7 as average reliability-wise, and FX is more or less at the same level.That apart, owners of different cars powered by the same engine as CX-7 rank it on average as 4.7, while the one under the competitor's bonnet gets 5.0 out of 5.

Infiniti is undoubtly more agile, reaching 100km/h in 1.1 seconds less than its competitor. In addition to that it accelerates all the way to 233 kilometers per hour, 23km/h more than the other car. When it comes to fuel economy the winner has to be CX-7, averaging around 10.2 liters of fuel per 100 kilometers (28 mpg), in combined cycle. We can't ignore that 18% difference compared to Infiniti FX.

Mazda 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, Infiniti FX beats the other contender by far, making it the best choice without even considering other things. It all continues in the same 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 Infiniti. 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.
