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 5-door hatchback 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 100hp engine designed by Mazda.

Both vehicles got tested by European New Car Assessment Programme (Euro NCAP), 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 small family car segment, which is generally classifying them somewhere in the middle safety-wise, but that fact doesn't break the tie between the two cars. Furthermore, when it comes to weight, a factor that most people underestimate, Civic offers a marginal difference of 4% more metal.

I don't like generalizing things when it comes to reliability, although it does seem that Honda does have a slight advantage, when all the models are taken into account. That's the official data, 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. Some independent research have also placed Civic as average reliability-wise, and 3 is more or less at the same level.Above it all, drivers of cars with the same engine as Civic rank it on average as 5.0, while the one under the competitor's bonnet gets 4.8 out of 5.

Honda is undoubtly more agile, reaching 100km/h in 2.4 seconds less than its competitor. In addition to that it accelerates all the way to 220 kilometers per hour, 38km/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 14% difference compared to Civic.

Honda 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 being considerably quicker, thus putting more smile on driver's face. 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. 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.
