Overview

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?

Safety

Both vehicles got tested by European New Car Assessment Programme (Euro NCAP), with the Hyundai being a slightly better choice apparently. 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, but it doesn't do much to help us decide between the two. On the other hand, taking kerb weight as an important factor into account, Rio offers a marginal difference of 6% more metal.

Reliability

I don't like generalizing things when it comes to reliability, although it does seem that Hyundai does have a slight advantage, at least on all of the models level. That's the official data, 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. Above it all, drivers of cars with the same engine as these two vehicles rank it on average as 5.0 out of 5.

Performance & Fuel economy

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 the winner has to be Rio, averaging around 4.5 liters of fuel per 100 kilometers (63 mpg), in combined cycle. We can't ignore that 16% difference compared to i20.

Verdict

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 , on the other hand, consumps significantly less fuel, and that's a big plus. No mistake, whatever you decide here, but I'd still go for the KIA. In any case that's my personal view, built upon all the data available to me. What should decide here though is the way you feel about the two vehicles, and I hope you'll find my guidelines useful in the process.
