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 90hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 109hp engine designed by Hyundai.

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. Moving further on, let's take a closer look at some additional safety-related facts. Both vehicles belong to the city car segment, which is generally not a very good thing safety-wise, still it doesn't help us solve our dilemma, does it?

Reliability is not the best thing to consider on the make level, but it is worth mentioning that Mazda does have a slight advantage, all the models observed together. 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.Above it all, drivers of cars with the same engine as the Japanese car rank it on average as 5.0, while the one under the competitor's bonnet gets 4.5 out of 5.

There's not enough data for me to elaborate on the subject, I'm affraid.

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 this case though, it seems that both cars show similar levels of passenger protection all together, so that won't break a tie. When it comes to performance, both vehicles provide similar experience, so I wouldn't point any of them out. Fuel consumption is more or less the same. It's really tough to make a final decision here, but if I'd need to, I'd say Mazda. Nevertheless, let's not forget that people have different preferences and needs, so what really counts is your personal feel. I'm only here to help. In case you have two minutes to spare I invite you to define your needs, desires and budget and see which car would be chosen by the virtual adviser™, among thousands of similar, yet so different vehicles.
