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.

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. 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, when it comes to weight, a factor that most people underestimate, the French car offers a considerable difference of 19% more metal.

Manufacturers have been building their reliability reputation for decades now and, generally speaking, it appears that Hyundai does have a slight advantage, all the models observed together. 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. The same official information place C5 as average reliability-wise, and i40 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 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. 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.
