Well, these are two pretty similar cars we have here! It's only details that could potentially make the difference. Considering they both belong to the small family car segment and utilize the same 4-door sedan body style and the front wheel drive system, it all comes up to the specific petrol engine choice they offer. The first one has a Honda-engineered powertrain under the hood, a 4-cylinder, 16-valves 182hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 120hp 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. That aside, let's consider some other aspects which affect safety. Both vehicles belong to the small family car segment, which is generally classifying them somewhere in the middle 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, Civic offers a marginal difference of 3% more metal.

I don't like generalizing things when it comes to reliability, although it does seem that Honda does have a slight advantage, at least on all of the models level. These are the official statistics, while our visitors describe reliability of Honda with an average rating of 4.7, and models under the Mazda badge with 4.4 out of 5. The same official information place Civic 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 Civic rank it on average as 4.0, while the one under the competitor's bonnet gets 5.0 out of 5.

Honda is a bit more agile, reaching 100km/h in 0.7 seconds less than its competitor. In addition to that it accelerates all the way to 210 kilometers per hour, 12km/h more than the other car. When it comes to fuel economy the winner has to be Mazda 3, averaging around 5.1 liters of fuel per 100 kilometers (55 mpg), in combined cycle. We can't ignore that 12% difference compared to Civic.

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, Civic offers slightly better overall protection and takes the lead. It all continues in the same direction, with Honda outracing its opponent in any situation possible, making it better choice for boy racers. It does come at a cost though, and that's the fuel consumption... It's really tough to make a final decision here, but if I'd need to, I'd say 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.
