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 large family car segment and utilize the same 4-door sedan 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 4-cylinder, 16-valves 177hp unit, while the other one gets its power and torque from a 6-cylinder, 24-valves 190hp engine designed by Hyundai.

The fact that the KIA got tested by the European New Car Assessment Programme (Euro NCAP), while the other contender didn't, offers a slight advantage, as the 4-star rating is better than none. Still, apart from the official crash test results there are other things we need to be aware of. Both vehicles belong to the large family car segment, which is generally a 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 4% more metal.

I don't like generalizing things when it comes to reliability, although it does seem that Nissan does have a slight advantage, when all the models are taken into account. These are the results of an independent reasearch, 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. Unfortunatelly, I don't have enough insight that would allow me to comment in more details on the specific models 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 4.8 out of 5.

Nissan is undoubtly more agile, reaching 100km/h in 1 seconds less than its competitor. In addition to that it accelerates all the way to 235 kilometers per hour, 15km/h more than the other car. When it comes to fuel economy the winner has to be the Japanese car, averaging around 7.3 liters of fuel per 100 kilometers (39 mpg), in combined cycle. We can't ignore that 26% 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 beats the other contender by far, making it the best choice without even considering other things. 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! It's really tough to make a final decision here, but if I'd need to, I'd say Nissan. 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.
