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 diesel engine choice they offer. The first one has a Ford-engineered powertrain under the hood, a 6-cylinder, 24-valves 241hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 136hp engine designed by Hyundai.

Both vehicles got tested by European New Car Assessment Programme (Euro NCAP), with the same number of safety stars gained in the process. 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 that fact doesn't break the tie between the two cars. Furthermore, taking kerb weight as an important factor into account, the French car offers a considerable difference of 19% more metal.

Reliability is not the best thing to consider on the make level, but it is worth mentioning that Hyundai 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 Citroen with an average rating of 4.1, and models under the Hyundai badge with 4.5 out of 5. Independent research findings rank C5 as average reliability-wise, and i40 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 3.0, while the one under the competitor's bonnet gets 5.0 out of 5.

Citroen is undoubtly more agile, reaching 100km/h in 2.3 seconds less than its competitor. In addition to that it accelerates all the way to 243 kilometers per hour, 42km/h more than the other car. When it comes to fuel economy an obvious choice would be the Korean car, averaging around 4.5 liters of fuel per 100 kilometers (63 mpg), in combined cycle. That's 60% difference compared to the French car!

Hyundai is apparently more reliable, not too much, but just enough. 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 French car offers significantly better overall protection, taking the lead here. It all continues in the same direction, with Citroen being considerably quicker, thus putting more smile on driver's face. It does come at a cost though, and that's the fuel consumption... It's not difficult to say then that if I'd need to make a choice, it would definitely be the Hyundai. 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.
