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.

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. Furthermore, when it comes to weight, a factor that most people underestimate, Citroen C5 offers a considerable difference of 24% more metal.

I don't like generalizing things when it comes to reliability, although it does seem that Renault does have a slight advantage, all the models observed together. That's the official data, while our visitors describe reliability of Citroen with an average rating of 4.0, and models under the Renault badge with 4.2 out of 5. Some independent research have also placed C5 as average reliability-wise, and Laguna is more or less at the same level.That apart, owners of different cars powered by the same engine 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 outracing its opponent in any situation possible, making it better choice for boy racers. 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 Renault. 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.
