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 5-door wagon 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 225hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 250hp 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 same number of safety stars gained in the process. That aside, let's consider some other aspects which affect safety. 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? 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 6% more metal.

I don't like generalizing things when it comes to reliability, although it does seem that Renault 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 Renault, as well as KIA, with the same average rating of 4.2 out of 5. The same official information place Talisman as average reliability-wise, and Optima is more or less at the same level.We should definitely mention that owners of cars with the same powertrain as the French car rank it on average as 4.0, while the one under the competitor's bonnet gets 3.0 out of 5.

Renault is a bit more agile, reaching 100km/h in 0.1 seconds less than its competitor. In addition to that it accelerates all the way to 234 kilometers per hour, 2km/h more than the other car. When it comes to fuel economy the winner has to be the French car, averaging around 7.2 liters of fuel per 100 kilometers (39 mpg), in combined cycle. We can't ignore that 14% difference compared to the Korean car.

Renault 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 slightly better overall protection and takes the lead. From there things take a different direction, with Renault being considerably quicker, thus putting more smile on driver's face. To make things even better, it consumps less fuel! All together, there's not much more to say, in this case I wouldn't even consider anything but Renault. 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. 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.
