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 Peugeot-engineered . The first one has a 4-cylinder, 16-valves 136hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 170hp 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, but that fact doesn't break the tie between the two cars. On the other hand, when it comes to weight, a factor that most people underestimate, 407 offers a marginal difference of 6% 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. That's the official data, 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. The same official information place C5 as average reliability-wise, and 407 is more or less at the same level.We should definitely mention that owners of cars with the same powertrain as Citroen C5 rank it on average as 4.2, while the one under the competitor's bonnet gets 4.3 out of 5.

Peugeot is undoubtly more agile, reaching 100km/h in 2.6 seconds less than its competitor. In addition to that it accelerates all the way to 221 kilometers per hour, 22km/h more than the other car. When it comes to fuel economy things look pretty much the same for both cars, averaging around 6.1 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, 407 offers slightly better overall protection and takes the lead. It all continues in the same direction, with Peugeot being considerably quicker, thus putting more smile on driver's face. It does come at a cost though, and that's the fuel consumption... It's really tough to make a final decision here, but if I'd need to, I'd say Peugeot.
