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. The first one has a Ford-engineered powertrain under the hood, a 6-cylinder, 24-valves 204hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 170hp engine designed by Peugeot.

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. Moving further on, let's take a closer look at some additional safety-related facts. 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, 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. That's the official data, 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. Independent research findings rank 407 as average reliability-wise, and C5 is more or less at the same level.Above it all, drivers of cars with the same engine as 407 rank it on average as 4.0, while the one under the competitor's bonnet gets 4.3 out of 5.

Citroen is a bit more agile, reaching 100km/h in 0.1 seconds less than its competitor. Still, it lacks the power to win the top speed competition, topping at 217 kilometers per hour, 11km/h less than the other car. When it comes to fuel economy an obvious choice would be Citroen C5, averaging around 6.2 liters of fuel per 100 kilometers (46 mpg), in combined cycle. That's 37% difference compared to 407!

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. It all continues in the same direction, with Citroen offering somewhat better performance, just enough to call it quicker. 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 Citroen. 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.
