We are here considering two somewhat similar cars, but we can't deny some of the obvious differences. For a start, they are not even classified under the same segment, with the BMW being a executive car and the Infiniti representing sports car vehicle class. The first one has a BMW-engineered powertrain under the hood, a 8-cylinder, 32-valves 625hp unit, while the other one gets its power and torque from a 6-cylinder, 24-valves 405hp engine designed by Nissan.

Unfortunatelly, neither of the two vehicles was submitted to the European New Car Assessment Programme (Euro NCAP) testing. This makes it virtually impossible for me to pick one over the other and I'm generally against buying such cars as the safety should really always come first. Still, apart from the official crash test results there are other things we need to be aware of. The first vehicle is a executive car and that spells a huge advantage compared to the sports car competitor, at least that's what statistics show. Furthermore, if we'd like to consider vehicle mass in this context too, which we definitely should, the German car offers a marginal difference of 9% 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. These are the results of an independent reasearch, while our visitors describe reliability of BMW with an average rating of 4.1, and models under the Infiniti badge with 4.6 out of 5. Unfortunatelly, I don't have enough insight that would allow me to comment in more details on the specific models level. We should definitely mention that owners of cars with the same powertrain as the German car rank it on average as 3.0 out of 5, exactly the same as the other one.

BMW 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 305 kilometers per hour, 55km/h more than the other car. When it comes to fuel economy the winner has to be the Japanese car, averaging around 9.1 liters of fuel per 100 kilometers (31 mpg), in combined cycle. We can't ignore that 15% difference compared to the German car.

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, the German car beats the other contender by far, making it the best choice without even considering other things. It all continues in the same direction, with BMW 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 BMW. 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.
