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. 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 that fact doesn't break the tie between the two cars. On the other hand, if we'd like to consider vehicle mass in this context too, which we definitely should, Rio offers a marginal difference of 1% more metal.

Reliability is not the best thing to consider on the make level, but it is worth mentioning that Hyundai 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 Hyundai with an average rating of 4.5, and models under the KIA badge with 4.2 out of 5. Unfortunatelly, I don't have enough insight that would allow me to comment in more details on the specific models level. We should definitely mention that owners of cars with the same powertrain as these two vehicles rank it on average as 5.0 out of 5.

KIA is a bit more agile, reaching 100km/h in 0.1 seconds less than its competitor. Still, it lacks the power to win the top speed competition, topping at 186 kilometers per hour, 2km/h less than the other car. When it comes to fuel economy things look pretty much the same for both cars, averaging around 4.8 liters of fuel per 100 kilometers (59 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 my opinion, everything taken into account, i20 offers slightly better overall protection and takes the lead. When it comes to performance, both vehicles provide similar experience, so I wouldn't point any of them out. Rio still consumps less fuel, which needs to be taken into consideration. At the end, as much as I'd like to give you a winner here, it's simply a pure tie if you ask me. 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.
