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 city 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 Mazda-engineered powertrain under the hood, a 4-cylinder, 16-valves 103hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 109hp engine designed by Hyundai.

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. Still, apart from the official crash test results there are other things we need to be aware of. Both vehicles belong to the city car segment, which is generally not a very good thing safety-wise, but it doesn't do much to help us decide between the two. On the other hand, if we'd like to consider vehicle mass in this context too, which we definitely should, the Korean car offers a considerable difference of 10% more metal.

I don't like generalizing things when it comes to reliability, although it does seem that Mazda does have a slight advantage, when all the models are taken into account. These are the results of an independent reasearch, while our visitors describe reliability of Mazda with an average rating of 4.4, and models under the KIA badge with 4.6 out of 5. The same official information place 2 as average reliability-wise, and Rio is more or less at the same level.We should definitely mention that owners of cars with the same powertrain as the Japanese car rank it on average as 3.0, while the one under the competitor's bonnet gets 4.5 out of 5.

Mazda 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 186 kilometers per hour, 3km/h more than the other car. When it comes to fuel economy the winner has to be the Korean car, averaging around 5.1 liters of fuel per 100 kilometers (55 mpg), in combined cycle. We can't ignore that 14% difference compared to the Japanese car.

KIA 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 Korean car offers significantly better overall protection, taking the lead here. From there things take a different direction, with Mazda offering somewhat better performance, just enough to call it quicker. 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 KIA. 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.
