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 diesel engine choice they offer. Both the engines are Hyundai-engineered . The first one has a 4-cylinder, 16-valves 75hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 90hp one.

Both vehicles got tested by European New Car Assessment Programme (Euro NCAP), 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 marginal difference of 6% 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, 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 4.2, and models under the Hyundai badge with 4.5 out of 5. The same official information place Rio as average reliability-wise, and i20 is more or less at the same level.That apart, owners of different cars powered by the same engine as Rio rank it on average as 3.0, while the one under the competitor's bonnet gets 4.8 out of 5.

Hyundai is undoubtly more agile, reaching 100km/h in 1.9 seconds less than its competitor. In addition to that it accelerates all the way to 175 kilometers per hour, 10km/h more than the other car. When it comes to fuel economy things look pretty much the same for both cars, averaging around 3.6 liters of fuel per 100 kilometers (78 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, i20 offers slightly better overall protection and takes the lead. It all continues in the same direction, with Hyundai outracing its opponent in any situation possible, making it better choice for boy racers. 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 Hyundai. 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.
