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 Peugeot-engineered powertrain under the hood, a 4-cylinder, 16-valves 163hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 173hp engine designed by Renault.

The first thing to look into here would be the results from European New Car Assessment Programme (Euro NCAP) tests performed on the two cars. Good thing is that both vehicles got tested, 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 it doesn't do much to help us decide between the two. Furthermore, if we'd like to consider vehicle mass in this context too, which we definitely should, Citroen C5 offers a marginal difference of 5% more metal.

I don't like generalizing things when it comes to reliability, although it does seem that Renault does have a slight advantage, when all the models are taken into account. That's the official data, while our visitors describe reliability of Citroen, as well as Renault, with the same average rating of 4.1 out of 5. Independent research findings rank C5 as average reliability-wise, and Laguna is more or less at the same level.Above it all, drivers of cars with the same engine as Citroen C5 rank it on average as 4.7, while the one under the competitor's bonnet gets 4.8 out of 5.

Renault is undoubtly more agile, reaching 100km/h in 1.4 seconds less than its competitor. In addition to that it accelerates all the way to 215 kilometers per hour, 5km/h more than the other car. When it comes to fuel economy the winner has to be Citroen C5, averaging around 5.2 liters of fuel per 100 kilometers (54 mpg), in combined cycle. We can't ignore that 21% difference compared to Laguna.

Renault 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 Renault being considerably quicker, thus putting more smile on driver's face. It does come at a cost though, and that's the fuel consumption... No mistake, whatever you decide here, but I'd still go for the Citroen. 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.
