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 Hyundai-engineered powertrain under the hood, a 6-cylinder, 24-valves 190hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 177hp engine designed by Nissan.

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, still it doesn't help us solve our dilemma, does it? Furthermore, when it comes to weight, a factor that most people underestimate, the Korean car offers a marginal difference of 4% more metal.

Manufacturers have been building their reliability reputation for decades now and, generally speaking, it appears that Nissan does have a slight advantage, at least on all of the models level. These are the results of an independent reasearch, while our visitors describe reliability of KIA with an average rating of 4.6, and models under the Nissan badge with 4.3 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 the Korean car rank it on average as 4.8, while the one under the competitor's bonnet gets 3.0 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. 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.
