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 4-door sedan body style and the front wheel drive system, it all comes up to the specific diesel engine choice they offer. The first one has a Hyundai-engineered powertrain under the hood, a 4-cylinder, 16-valves 90hp unit, while the other one gets its power and torque from a 4-cylinder, 8-valves 86hp engine designed by Renault.

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 same number of safety stars gained in the process. 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. Furthermore, taking kerb weight as an important factor into account, the Korean car offers a considerable difference of 16% more metal.

Reliability is not the best thing to consider on the make level, but it is worth mentioning that Renault does have a slight advantage, at least on all of the models level. That's the official data, while our visitors describe reliability of KIA with an average rating of 4.6, and models under the Renault badge with 4.1 out of 5. The same official information place Rio as average reliability-wise, and Thalia is more or less at the same level.That apart, owners of different cars powered by the same engine as the Korean car rank it on average as 4.8, while the one under the competitor's bonnet gets 4.3 out of 5.

Renault is undoubtly more agile, reaching 100km/h in 1.9 seconds less than its competitor. In addition to that it accelerates all the way to 177 kilometers per hour, 5km/h more than the other car. When it comes to fuel economy things look pretty much the same for both cars, averaging around 4.1 liters of fuel per 100 kilometers (70 mpg), in combined cycle.

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 significantly better overall protection, taking the lead here. From there things take a different direction, with Renault being considerably quicker, thus putting more smile on driver's face. It does come at a cost though, and that's the fuel consumption... I believe that, when we take all into account, we have only one winner here - 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.
