Two significantly similar cars, no doubt about that. Still, each one has something different to offer. Having both cars powered by diesel engines and utilizing the 5-door wagon body style within the same 'Large family car' segment, the only major difference here really is their wheel drive configuration (front for the Mazda and rear in the case of the BMW). The first one has a Mazda-engineered powertrain under the hood, a 4-cylinder, 16-valves 175hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 184hp engine designed by BMW.

Both vehicles got tested by European New Car Assessment Programme (Euro NCAP), with the same number of safety stars gained in the process. Moving further on, let's take a closer look at some additional safety-related facts. Both vehicles belong to the large family car segment, which is generally a good thing safety-wise, still it doesn't help us solve our dilemma, does it? On the other hand, when it comes to weight, a factor that most people underestimate, the German car offers a marginal difference of 4% more metal.

Reliability is not the best thing to consider on the make level, but it is worth mentioning that Mazda as a brand displays somewhat better results, when all the models are taken into account. These are the official statistics, while our visitors describe reliability of Mazda with an average rating of 4.4, and models under the BMW badge with 4.1 out of 5. The same official information place 6 as average reliability-wise, and 3 Series is more or less at the same level.Above it all, drivers of cars with the same engine as the Japanese car rank it on average as 4.5, while the one under the competitor's bonnet gets 3.8 out of 5.

BMW is a bit more agile, reaching 100km/h in 0.9 seconds less than its competitor. In addition to that it accelerates all the way to 230 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 4.8 liters of fuel per 100 kilometers (59 mpg), in combined cycle.

Mazda 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 offers slightly better overall protection and takes the lead. It all continues in the same direction, with BMW outracing its opponent in any situation possible, making it better choice for boy racers. To make things even better, it consumps less fuel! 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.
