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. Both the engines are Ford-engineered . The first one has a 6-cylinder, 24-valves 241hp unit, while the other one gets its power and torque from a 6-cylinder, 24-valves 204hp one.

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, still it doesn't help us solve our dilemma, does it? Furthermore, if we'd like to consider vehicle mass in this context too, which we definitely should, Citroen C5 offers a considerable difference of 10% more metal.

I don't like generalizing things when it comes to reliability, although it does seem that Peugeot 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 Peugeot badge with 4.3 out of 5. Some independent research have also placed C5 as average reliability-wise, and 407 is more or less at the same level.That apart, owners of different cars powered by the same engine as Citroen C5 rank it on average as 3.0, while the one under the competitor's bonnet gets 4.0 out of 5.

Citroen is a bit more agile, reaching 100km/h in 0.9 seconds less than its competitor. In addition to that it accelerates all the way to 242 kilometers per hour, 14km/h more than the other car. When it comes to fuel economy the winner has to be Citroen C5, averaging around 7.4 liters of fuel per 100 kilometers (38 mpg), in combined cycle. We can't ignore that 15% difference compared to 407.

Peugeot 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, Citroen C5 offers significantly better overall protection, taking the lead here. It all continues in the same direction, with Citroen 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 Citroen. 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. In case you have two minutes to spare I invite you to define your needs, desires and budget and see which car would be chosen by the virtual adviser™, among thousands of similar, yet so different vehicles.
