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 large 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 diesel engine choice they offer. The first one has a Mazda-engineered powertrain under the hood, a 4-cylinder, 16-valves 185hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 136hp engine designed by Hyundai.

Both vehicles got tested by European New Car Assessment Programme (Euro NCAP), with the same number of safety stars gained in the process. 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. Furthermore, if we'd like to consider vehicle mass in this context too, which we definitely should, the Japanese car offers a marginal difference of 7% more metal.

Reliability is not the best thing to consider on the make level, but it is worth mentioning that both brands display similar results in faults and breakdowns, at least on all of the models level. These are the official statistics, while our visitors describe reliability of Mazda with an average rating of 4.4, and models under the Hyundai badge with 4.5 out of 5. Independent research findings rank 6 as average reliability-wise, and i40 is more or less at the same level.That apart, owners of different cars powered by the same engine as the Japanese car rank it on average as 5.0 out of 5, exactly the same as the other one.

Mazda is undoubtly more agile, reaching 100km/h in 1.9 seconds less than its competitor. In addition to that it accelerates all the way to 218 kilometers per hour, 17km/h more than the other car. When it comes to fuel economy the winner has to be the Korean car, averaging around 4.5 liters of fuel per 100 kilometers (63 mpg), in combined cycle. We can't ignore that 20% difference compared to the Japanese car.

Hyundai 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, the Japanese car offers slightly better overall protection and takes the lead. It all continues in the same direction, with Mazda 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 Hyundai. 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.
