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 4-door sedan 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?

A starting point here would be to take a look at the results from European New Car Assessment Programme (Euro NCAP) tests which were performed on both of the cars, 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, if we'd like to consider vehicle mass in this context too, which we definitely should, Citroen C5 offers a marginal difference of 3% more metal.

I don't like generalizing things when it comes to reliability, although it does seem that Peugeot does have a slight advantage, at least on all of the models level. These are the official statistics, while our visitors describe reliability of Citroen with an average rating of 4.0, and models under the Peugeot badge with 4.3 out of 5. The same official information place C5 as average reliability-wise, and 508 is more or less at the same level.Above it all, drivers of cars with the same engine as these two vehicles rank it on average as 4.2 out of 5.

Peugeot is undoubtly more agile, reaching 100km/h in 2 seconds less than its competitor. In addition to that it accelerates all the way to 203 kilometers per hour, 15km/h more than the other car. When it comes to fuel economy things look pretty much the same for both cars, averaging around 6.2 liters of fuel per 100 kilometers (46 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 outracing its opponent in any situation possible, making it better choice for boy racers. Fuel consumption is more or less the same. 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.
