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 Mazda being a sports car and the BMW representing small family car vehicle class. The first one has a Mazda-engineered powertrain under the hood, a 4-cylinder, 16-valves 160hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 170hp engine designed by BMW.

The fact that the BMW 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. The first vehicle is a sports car, providing approximately same level of protection as the small family car competitor, at least that's what statistics show. On the other hand, if we'd like to consider vehicle mass in this context too, which we definitely should, the German car offers a considerable difference of 16% more metal.

Manufacturers have been building their reliability reputation for decades now and, generally speaking, it appears that Mazda as a brand displays somewhat better results, all the models observed together. That's the official data, while our visitors describe reliability of Mazda with an average rating of 4.4, and models under the BMW badge with 4.2 out of 5. Unfortunatelly, I don't have enough insight that would allow me to comment in more details on the specific models level. That apart, owners of different cars powered by the same engine as the Japanese car rank it on average as 3.0, while the one under the competitor's bonnet gets 4.3 out of 5.

Mazda is a bit more agile, reaching 100km/h in 0.2 seconds less than its competitor. Still, it lacks the power to win the top speed competition, topping at 218 kilometers per hour, 6km/h less than the other car. When it comes to fuel economy the winner has to be the German car, averaging around 6.6 liters of fuel per 100 kilometers (43 mpg), in combined cycle. We can't ignore that 15% difference compared to the Japanese car.

BMW 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. From there things take a different direction, with Mazda offering somewhat better performance, just enough to call it quicker. 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. 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™, out of 12.000+ vehicles we currently have in our database.
