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

The fact that the Mazda 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, still it doesn't help us solve our dilemma, does it? Furthermore, if we'd like to consider vehicle mass in this context too, which we definitely should, Infiniti EX offers a marginal difference of 4% more metal.

I don't like generalizing things when it comes to reliability, although it does seem that Mazda does have a slight advantage, all the models observed together. These are the results of an independent reasearch, while our visitors describe reliability of Infiniti with an average rating of 4.6, and models under the Mazda badge with 4.4 out of 5. Some independent research have also placed EX as average reliability-wise, and CX-7 is more or less at the same level.We should definitely mention that owners of cars with the same powertrain as Infiniti EX rank it on average as 5.0, while the one under the competitor's bonnet gets 4.7 out of 5.

Infiniti is undoubtly more agile, reaching 100km/h in 1.8 seconds less than its competitor. In addition to that it accelerates all the way to 240 kilometers per hour, 29km/h more than the other car. When it comes to fuel economy the winner has to be CX-7, averaging around 10.4 liters of fuel per 100 kilometers (27 mpg), in combined cycle. We can't ignore that 8% difference compared to Infiniti EX.

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, CX-7 offers much better overall protection, which launches it ahead of the other contender. 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... It's not difficult to say then that if I'd need to make a choice, it would definitely be the Mazda. 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.
