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. Both the engines are Peugeot-engineered . The first one has a 4-cylinder, 16-valves 180hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 163hp one.

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 it doesn't do much to help us decide between the two. Furthermore, taking kerb weight as an important factor into account, Citroen C5 offers a marginal difference of 1% 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 official statistics, while our visitors describe reliability of Peugeot with an average rating of 4.3, and models under the Citroen badge with 4.1 out of 5. The same official information place 508 as average reliability-wise, and C5 41% below the first one. Above it all, drivers of cars with the same engine as 508 rank it on average as 4.5, while the one under the competitor's bonnet gets 4.7 out of 5.

Peugeot is a bit more agile, reaching 100km/h in 0.7 seconds less than its competitor. In addition to that it accelerates all the way to 223 kilometers per hour, 13km/h more than the other car. When it comes to fuel economy the winner has to be 508, averaging around 4.2 liters of fuel per 100 kilometers (67 mpg), in combined cycle. We can't ignore that 17% difference compared to Citroen C5.

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. 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 Peugeot. 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. 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.
