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 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 150hp 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 same number of safety stars gained in the process. Still, apart from the official crash test results there are other things we need to be aware of. 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, if we'd like to consider vehicle mass in this context too, which we definitely should, Legacy offers a marginal difference of 5% more metal.

Manufacturers have been building their reliability reputation for decades now and, generally speaking, it appears that Mazda does have a slight advantage, at least on all of the models level. 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. Independent research findings rank Legacy as average reliability-wise, and 6 is more or less at the same level.That apart, owners of different cars powered by the same engine as Legacy rank it on average as 4.8, while the one under the competitor's bonnet gets 5.0 out of 5.

Subaru is a bit more agile, reaching 100km/h in 0.6 seconds less than its competitor. Still, it lacks the power to win the top speed competition, topping at 206 kilometers per hour, 5km/h less than the other car. When it comes to fuel economy the winner has to be Mazda 6, averaging around 7 liters of fuel per 100 kilometers (40 mpg), in combined cycle. We can't ignore that 23% difference compared to Legacy.

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, Legacy offers slightly better overall protection and takes the lead. When it comes to performance, both vehicles provide similar experience, so I wouldn't point any of them out. Mazda 6 , on the other hand, consumps significantly less fuel, and that's a big plus. It's not difficult to say then that if I'd need to make a choice, it would definitely be the Mazda. 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. Also, you could use the oportunity to find out which car, everything taken into account, would be the perfect choice for you in the eyes of the virtual adviser™, among thousands of similar, yet so different vehicles.
