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 petrol engine choice they offer. The first one has a Nissan-engineered powertrain under the hood, a 3-cylinder, 12-valves 98hp unit, while the other one gets its power and torque from a 4-cylinder, 12-valves 87hp engine designed by Hyundai.

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 KIA 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 it doesn't do much to help us decide between the two. On the other hand, if we'd like to consider vehicle mass in this context too, which we definitely should, the Korean car offers a marginal difference of 5% more metal.

I don't like generalizing things when it comes to reliability, although it does seem that Nissan does have a slight advantage, all the models observed together. That's the official data, while our visitors describe reliability of Nissan with an average rating of 4.3, and models under the KIA badge with 4.6 out of 5. Some independent research have also placed Micra as average reliability-wise, and Rio is more or less at the same level.That apart, owners of different cars powered by the same engine as the Japanese car rank it on average as 3.0, while the one under the competitor's bonnet gets 5.0 out of 5.

Nissan is undoubtly more agile, reaching 100km/h in 1.8 seconds less than its competitor. In addition to that it accelerates all the way to 180 kilometers per hour, 8km/h more than the other car. When it comes to fuel economy the winner has to be the Japanese car, averaging around 4.1 liters of fuel per 100 kilometers (69 mpg), in combined cycle. We can't ignore that 17% difference compared to the Korean car.

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, the Korean car offers much better overall protection, which launches it ahead of the other contender. From there things take a different direction, with Nissan being considerably quicker, thus putting more smile on driver's face. To make things even better, it consumps less fuel! No mistake, whatever you decide here, but I'd still go for the Nissan. 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.
