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 Infiniti being a sports car and the BMW representing executive car vehicle class. The first one has a Mercedes Benz-engineered powertrain under the hood, a 4-cylinder, 16-valves 211hp unit, while the other one gets its power and torque from a 6-cylinder, 24-valves 340hp engine designed by BMW.

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. That aside, let's consider some other aspects which affect safety. The second 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, taking kerb weight as an important factor into account, the German car offers a marginal difference of 8% 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, all the models observed together. These are the official statistics, while our visitors describe reliability of Infiniti with an average rating of 4.6, and models under the BMW badge with 4.1 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 Japanese car rank it on average as 5.0, while the one under the competitor's bonnet gets 1.0 out of 5.

BMW is undoubtly more agile, reaching 100km/h in 2.3 seconds less than its competitor. In addition to that it accelerates all the way to 250 kilometers per hour, 15km/h more than the other car. When it comes to fuel economy things look pretty much the same for both cars, averaging around 7 liters of fuel per 100 kilometers (40 mpg), in combined cycle.

Infiniti is apparently more reliable, not too much, but just enough. 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... It's not difficult to say then that if I'd need to make a choice, it would definitely be the BMW. 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. In case you have two minutes to spare I invite you to define your needs, desires and budget and see which car would be chosen by the virtual adviser™, among thousands of similar, yet so different vehicles.
