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 Hyundai-engineered powertrain under the hood, a 4-cylinder, 16-valves 115hp unit, while the other one gets its power and torque from a 4-cylinder, 8-valves 112hp engine designed by Peugeot.

Both vehicles got tested by European New Car Assessment Programme (Euro NCAP), 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, taking kerb weight as an important factor into account, the French car offers a marginal difference of 2% more metal.

I don't like generalizing things when it comes to reliability, although it does seem that Hyundai does have a slight advantage, all the models observed together. That's the official data, while our visitors describe reliability of Hyundai with an average rating of 4.5, and models under the Citroen badge with 4.1 out of 5. Independent research findings rank i40 as average reliability-wise, and C5 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 4.3, while the one under the competitor's bonnet gets 4.0 out of 5.

Citroen is a bit more agile, reaching 100km/h in 0.1 seconds less than its competitor. Still, it lacks the power to win the top speed competition, topping at 190 kilometers per hour, 2km/h less 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. It all continues in the same direction, with Citroen offering somewhat better performance, just enough to call it quicker. 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 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.
