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, 8-valves 115hp unit, while the other one gets its power and torque from a 4-cylinder, 8-valves 112hp one.

Both vehicles got tested by European New Car Assessment Programme (Euro NCAP), 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. On the other hand, when it comes to weight, a factor that most people underestimate, Citroen C5 offers a marginal difference of 7% 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 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 is more or less at the same level.We should definitely mention that owners of cars with the same powertrain as 508 rank it on average as 4.2, while the one under the competitor's bonnet gets 4.0 out of 5.

Peugeot is undoubtly more agile, reaching 100km/h in 1.5 seconds less than its competitor. Still, it lacks the power to win the top speed competition, topping at 190 kilometers per hour, exactly the same as the other car does. When it comes to fuel economy things look pretty much the same for both cars, averaging around 4.9 liters of fuel per 100 kilometers (58 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.
