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 'Small 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 230hp 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 Mazda being a slightly better choice apparently. Still, apart from the official crash test results there are other things we need to be aware of. Both vehicles belong to the small family car segment, which is generally classifying them somewhere in the middle safety-wise, but it doesn't do much to help us decide between the two. Furthermore, if we'd like to consider vehicle mass in this context too, which we definitely should, Impreza offers a considerable difference of 13% 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 Impreza as average reliability-wise, and 3 is more or less at the same level.That apart, owners of different cars powered by the same engine as Impreza rank it on average as 4.0, while the one under the competitor's bonnet gets 5.0 out of 5.

Subaru is way more agile, reaching 100km/h in 4.6 seconds less than its competitor. Still, it lacks the power to win the top speed competition, topping at 209 kilometers per hour, 3km/h less than the other car. When it comes to fuel economy an obvious choice would be Mazda 3, averaging around 6.8 liters of fuel per 100 kilometers (42 mpg), in combined cycle. That's 53% difference compared to Impreza!

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 this case though, it seems that both cars show similar levels of passenger protection all together, so that won't break a tie. But one thing that actually could is the performance, 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. 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.
