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 diesel engine choice they offer. The first one has a Renault-engineered powertrain under the hood, a 4-cylinder, 16-valves 129hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 141hp engine designed by Hyundai.

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. 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, but that fact doesn't break the tie between the two cars. On the other hand, when it comes to weight, a factor that most people underestimate, the Korean car offers a marginal difference of 3% 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, all the models observed together. That's the official data, while our visitors describe reliability of Renault with an average rating of 4.1, and models under the KIA badge with 4.6 out of 5. Independent research findings rank Talisman as average reliability-wise, and Optima is more or less at the same level.Above it all, drivers of cars with the same engine as the French car rank it on average as 4.6, while the one under the competitor's bonnet gets 5.0 out of 5.

KIA is a bit more agile, reaching 100km/h in 0.6 seconds less than its competitor. In addition to that it accelerates all the way to 200 kilometers per hour, exactly the same as the other car does. When it comes to fuel economy things look pretty much the same for both cars, averaging around 4.2 liters of fuel per 100 kilometers (67 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 slightly better overall protection and takes the lead. It all continues in the same direction, with KIA offering somewhat better performance, just enough to call it quicker. It does come at a cost though, and that's the fuel consumption... It's really tough to make a final decision here, but if I'd need to, I'd say KIA. Anyway, that's the most objective conclusion I could've came up with and it's based solely on the information found on this website. Aspects such as design, practicality, brand value and driving experience are there for you to measure them out.
