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 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, still it doesn't help us solve our dilemma, does it? On the other hand, taking kerb weight as an important factor into account, Lexus RX offers a marginal difference of 3% more metal.

I don't like generalizing things when it comes to reliability, although it does seem that Lexus does have a slight advantage, when all the models are taken into account. These are the official statistics, while our visitors describe reliability of Infiniti with an average rating of 4.5, 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 Infiniti FX rank it on average as 5.0, while the one under the competitor's bonnet gets 3.0 out of 5.

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 13% difference compared to Infiniti FX.

Infiniti 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 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 Infiniti. 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.
