Well, these are two pretty similar cars we have here! It's only details that could potentially make the difference. Not only that they both belong to the large family car segment and utilize the same 5-door wagon body style, they are even powered by the same Peugeot-developed petrol engine! There is not much there to point us towards one vehicle or the other. Or is it?

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. 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, taking kerb weight as an important factor into account, Citroen C5 offers a marginal difference of 3% more metal.

Manufacturers have been building their reliability reputation for decades now and, generally speaking, it appears that Peugeot 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 Peugeot badge with 4.3 out of 5. Some independent research have also placed C5 as average reliability-wise, and 508 is more or less at the same level.That apart, owners of different cars powered by the same engine as these two vehicles rank it on average as 4.1 out of 5.

Peugeot is undoubtly more agile, reaching 100km/h in 2.7 seconds less than its competitor. In addition to that it accelerates all the way to 203 kilometers per hour, 21km/h more than the other car. When it comes to fuel economy things look pretty much the same for both cars, averaging around 6.4 liters of fuel per 100 kilometers (44 mpg), in combined cycle.

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 slightly better overall protection and takes the lead. From there things take a different direction, with Peugeot being considerably quicker, thus putting more smile on driver's face. To make things even better, it consumps less fuel! I believe that, when we take all into account, we have only one winner here - the Peugeot. 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.
