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 diesel engine choice they offer. The first one has a Hyundai-engineered powertrain under the hood, a 4-cylinder, 16-valves 136hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 105hp engine designed by Mazda.

The first thing to look into here would be the results from European New Car Assessment Programme (Euro NCAP) tests performed on the two cars. Good thing is that both vehicles got tested, 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, 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, the Korean car offers a marginal difference of 1% more metal.

I don't like generalizing things when it comes to reliability, although it does seem that both brands display similar results in faults and breakdowns, all the models observed together. These are the official statistics, while our visitors describe reliability of Hyundai with an average rating of 4.5, and models under the Mazda badge with 4.4 out of 5. Independent research findings rank i30 as average reliability-wise, and 3 is more or less at the same level.We should definitely mention that owners of cars with the same powertrain as the Korean car rank it on average as 5.0, while the one under the competitor's bonnet gets 1.0 out of 5.

Hyundai is a bit more agile, reaching 100km/h in 0.8 seconds less than its competitor. In addition to that it accelerates all the way to 200 kilometers per hour, 15km/h more than the other car. When it comes to fuel economy things look pretty much the same for both cars, averaging around 3.9 liters of fuel per 100 kilometers (73 mpg), in combined cycle.

Hyundai is apparently more reliable, not too much, but just enough. 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 Korean car offers slightly better overall protection and takes the lead. It all continues in the same direction, with Hyundai offering somewhat better performance, just enough to call it quicker. 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.
