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 241hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 178hp engine designed by Renault.

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. 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. Furthermore, taking kerb weight as an important factor into account, Citroen C5 offers a considerable difference of 24% more metal.

Manufacturers have been building their reliability reputation for decades now and, generally speaking, it appears that Renault 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, as well as Renault, with the same average rating of 4.1 out of 5. The same official information place C5 as average reliability-wise, and Laguna 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 3.0, while the one under the competitor's bonnet gets 4.5 out of 5.

Citroen is a bit more agile, reaching 100km/h in 0.2 seconds less than its competitor. In addition to that it accelerates all the way to 242 kilometers per hour, 25km/h more than the other car. When it comes to fuel economy the winner has to be Laguna, averaging around 5.8 liters of fuel per 100 kilometers (49 mpg), in combined cycle. We can't ignore that 24% difference compared to Citroen C5.

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 significantly better overall protection, taking the lead here. It all continues in the same direction, with Citroen offering somewhat better performance, just enough to call it quicker. It does come at a cost though, and that's the fuel consumption... I believe that, when we take all into account, we have only one winner here - the Renault. 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.
