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 328hp unit, while the other one gets its power and torque from a 6-cylinder, 24-valves 279hp engine designed by Toyota.

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. 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. Furthermore, if we'd like to consider vehicle mass in this context too, which we definitely should, QX70 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 Lexus does have a slight advantage, at least on all of the models level. 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 Lexus badge with 4.9 out of 5. Unfortunatelly, I don't have enough insight that would allow me to comment in more details on the specific models level. Above it all, drivers of cars with the same engine as QX70 rank it on average as 3.0 out of 5, exactly the same as the other one.

Infiniti is undoubtly more agile, reaching 100km/h in 1.2 seconds less than its competitor. In addition to that it accelerates all the way to 233 kilometers per hour, 33km/h more than the other car. When it comes to fuel economy the winner has to be Lexus RX, averaging around 10.6 liters of fuel per 100 kilometers (27 mpg), in combined cycle. We can't ignore that 14% difference compared to QX70.

Lexus 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, QX70 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.
