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 (rear for the BMW and front in the case of the Mazda). The first one has a BMW-engineered powertrain under the hood, a 4-cylinder, 16-valves 122hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 121hp engine designed by Mazda.

A starting point here would be to take a look at the results from European New Car Assessment Programme (Euro NCAP) tests which were performed on both of the cars, with the BMW being a slightly better choice apparently. 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? Furthermore, taking kerb weight as an important factor into account, the German car offers a marginal difference of 1% 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. These are the official statistics, while our visitors describe reliability of BMW with an average rating of 4.2, and models under the Mazda badge with 4.4 out of 5. The same official information place 3 Series as average reliability-wise, and 6 is more or less at the same level.Above it all, drivers of cars with the same engine as the German car rank it on average as 4.8, while the one under the competitor's bonnet gets 4.4 out of 5.

Both of the cars accelerate exactly the same, so we couldn't put one above the other. Car No. 1 reaches top speed of 190 kilometers per hour, 14km/h more than the other car. When it comes to fuel economy things look pretty much the same for both cars, averaging around 6 liters of fuel per 100 kilometers (47 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 much better overall protection, which launches it ahead of the other contender. When it comes to performance, both vehicles provide similar experience, so I wouldn't point any of them out. the German car still consumps less fuel, which needs to be taken into consideration. All together, there's not much more to say, in this case I wouldn't even consider anything but BMW. In any case that's my personal view, built upon all the data available to me. What should decide here though is the way you feel about the two vehicles, and I hope you'll find my guidelines useful in the process.
