Well, these are two pretty similar cars we have here! It's only details that could potentially make the difference. Not only that they both belong to the city car segment and utilize the same 5-door hatchback body style, they are even powered by the same Hyundai-developed petrol engine! There is not much there to point us towards one vehicle or the other. Or is it?

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 Hyundai being a slightly better choice apparently. That aside, let's consider some other aspects which affect safety. Both vehicles belong to the city car segment, which is generally not a very 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, Rio offers a considerable difference of 14% more metal.

Manufacturers have been building their reliability reputation for decades now and, generally speaking, it appears that Hyundai does have a slight advantage, at least on all of the models level. These are the results of an independent reasearch, while our visitors describe reliability of KIA with an average rating of 4.6, and models under the Hyundai badge with 4.5 out of 5. Some independent research have also placed Rio as average reliability-wise, and i20 is more or less at the same level.We should definitely mention that owners of cars with the same powertrain as these two vehicles rank it on average as 4.1 out of 5.

Hyundai is a bit more agile, reaching 100km/h in 0.6 seconds less than its competitor. In addition to that it accelerates all the way to 184 kilometers per hour, 9km/h more than the other car. When it comes to fuel economy things look pretty much the same for both cars, averaging around 5.2 liters of fuel per 100 kilometers (55 mpg), in combined cycle.

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 this case though, it seems that both cars show similar levels of passenger protection all together, so that won't break a tie. But one thing that actually could is the performance, 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 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. 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™, out of 12.000+ vehicles we currently have in our database.
