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 Peugeot-engineered powertrain under the hood, a 4-cylinder, 8-valves 112hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 115hp 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, still it doesn't help us solve our dilemma, does it? Furthermore, taking kerb weight as an important factor into account, the French car offers a marginal difference of 4% more metal.

I don't like generalizing things when it comes to reliability, although it does seem that Hyundai does have a slight advantage, when all the models are taken into account. That's the official data, while our visitors describe reliability of Citroen with an average rating of 4.2, and models under the Hyundai badge with 4.5 out of 5. Some independent research have also placed 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 4.0, while the one under the competitor's bonnet gets 4.3 out of 5.

Hyundai is a bit more agile, reaching 100km/h in 0.4 seconds less than its competitor. In addition to that it accelerates all the way to 190 kilometers per hour, 3km/h more than the other car. When it comes to fuel economy the winner has to be the Korean car, averaging around 4.3 liters of fuel per 100 kilometers (66 mpg), in combined cycle. We can't ignore that 16% difference compared to the French car.

Hyundai 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 French car offers slightly better overall protection and takes the lead. From there things take a different direction, with Hyundai offering somewhat better performance, just enough to call it quicker. 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 Hyundai. 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.
