Virtual Adviser's™ opinion
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?Safety
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 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 it doesn't do much to help us decide between the two. 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
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. These are the official statistics, 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.Above it all, drivers of cars with the same engine as these two vehicles rank it on average as 4.8 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 175 kilometers per hour, exactly the same as the other car does. When it comes to fuel economy things look pretty much the same for both cars, averaging around 3.7 liters of fuel per 100 kilometers (76 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. From there things take a different direction, with KIA offering somewhat better performance, just enough to call it quicker. Fuel consumption is more or less the same. It's really tough to make a final decision here, but if I'd need to, I'd say 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. I suggest you spend two more minutes in order to find out which car, based on your needs and budget, would be picked by the virtual adviser™, among thousands of similar, yet so different vehicles.
