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 (4 x 4 for the Subaru and front in the case of the Mazda). The first one has a Subaru-engineered powertrain under the hood, a 4-cylinder, 16-valves 150hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 163hp engine designed by Mazda.

The first thing to look into here would be the results from European New Car Assessment Programme (Euro NCAP) tests performed on the two cars. Good thing is that both vehicles got tested, with the same number of safety stars gained in the process. That aside, let's consider some other aspects which affect safety. 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, when it comes to weight, a factor that most people underestimate, Legacy offers a marginal difference of 4% more metal.

I don't like generalizing things when it comes to reliability, although it does seem that Mazda does have a slight advantage, all the models observed together. That's the official data, while our visitors describe reliability of Subaru with an average rating of 4.2, and models under the Mazda badge with 4.4 out of 5. Some independent research have also placed Legacy as average reliability-wise, and 6 is more or less at the same level.We should definitely mention that owners of cars with the same powertrain as Legacy rank it on average as 4.7, while the one under the competitor's bonnet gets 3.0 out of 5.

Mazda is a bit more agile, reaching 100km/h in 0.4 seconds less than its competitor. In addition to that it accelerates all the way to 211 kilometers per hour, 8km/h more than the other car. When it comes to fuel economy the winner has to be Mazda 6, averaging around 5.4 liters of fuel per 100 kilometers (52 mpg), in combined cycle. We can't ignore that 13% difference compared to Legacy.

Subaru 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, Legacy offers slightly better overall protection and takes the lead. From there things take a different direction, with Mazda being considerably quicker, thus putting more smile on driver's face. 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 Mazda. 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.
