Virtual Adviser's™ opinion
Two significantly similar cars, no doubt about that. Still, each one has something different to offer. Having both cars powered by petrol engines and utilizing the 4-door sedan 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 4 x 4 in the case of the Subaru). The first one has a Mazda-engineered powertrain under the hood, a 4-cylinder, 16-valves 120hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 162hp engine designed by Subaru.
SafetyThe fact that the Mazda got tested by the European New Car Assessment Programme (Euro NCAP), while the other contender didn't, offers a slight advantage, as the 4-star rating is better than none. 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, but that fact doesn't break the tie between the two cars. On the other hand, taking kerb weight as an important factor into account, Legacy offers a marginal difference of 5% more metal.
ReliabilityManufacturers have been building their reliability reputation for decades now and, generally speaking, it appears that Mazda does have a slight advantage, 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 Subaru badge with 4.2 out of 5. The same official information place 6 as average reliability-wise, and Legacy is more or less at the same level.Above it all, drivers of cars with the same engine as Mazda 6 rank it on average as 5.0, while the one under the competitor's bonnet gets 4.8 out of 5.
Performance & Fuel economySubaru is undoubtly more agile, reaching 100km/h in 1.2 seconds less than its competitor. In addition to that it accelerates all the way to 209 kilometers per hour, 12km/h more than the other car. When it comes to fuel economy the winner has to be Mazda 6, averaging around 7.7 liters of fuel per 100 kilometers (37 mpg), in combined cycle. We can't ignore that 12% difference compared to Legacy.
Verdict
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, Mazda 6 offers much better overall protection, which launches it ahead of the other contender. From there things take a different direction, with Subaru being considerably quicker, thus putting more smile on driver's face. 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 Mazda. Anyway, that's the most objective conclusion I could've came up with and it's based solely on the information found on this website. Aspects such as design, practicality, brand value and driving experience are there for you to measure them out. 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.
