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 diesel engine! There is not much there to point us towards one vehicle or the other. Or is it?

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. 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, taking kerb weight as an important factor into account, i20 offers a marginal difference of 1% more metal.

Manufacturers have been building their reliability reputation for decades now and, generally speaking, it appears that Hyundai does have a slight advantage, all the models observed together. That's the official data, 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. Independent research findings rank Rio as average reliability-wise, and i20 is more or less at the same level.Above it all, drivers of cars with the same engine as these two vehicles rank it on average as 4.8 out of 5.

KIA is a bit more agile, reaching 100km/h in 0.2 seconds less than its competitor. In addition to that it accelerates all the way to 159 kilometers per hour, 1km/h more than the other car. When it comes to fuel economy things look pretty much the same for both cars, averaging around 3.4 liters of fuel per 100 kilometers (83 mpg), in combined cycle.

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, i20 offers slightly better overall protection and takes the lead. From there things take a different direction, with KIA offering somewhat better performance, just enough to call it quicker. To make things even better, it consumps less fuel! No mistake, whatever you decide here, but I'd still go for the KIA. 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.
