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 small family car segment and utilize the same 5-door hatchback 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, 8-valves 99hp unit, while the other one gets its power and torque from a 4-cylinder, 8-valves 90hp 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 small family car segment, which is generally classifying them somewhere in the middle safety-wise, but it doesn't do much to help us decide between the two. On the other hand, taking kerb weight as an important factor into account, Megane offers a marginal difference of 1% more metal.

Reliability is not the best thing to consider on the make level, but it is worth mentioning 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 with an average rating of 4.0, and models under the Renault badge with 4.2 out of 5. The same official information place C4 as average reliability-wise, and Megane is more or less at the same level.That apart, owners of different cars powered by the same engine as Citroen C4 rank it on average as 4.2, while the one under the competitor's bonnet gets 4.5 out of 5.

Citroen is undoubtly more agile, reaching 100km/h in 1 seconds less than its competitor. Still, it lacks the power to win the top speed competition, topping at 180 kilometers per hour, exactly the same as the other car does. When it comes to fuel economy the winner has to be Citroen C4, averaging around 3.3 liters of fuel per 100 kilometers (86 mpg), in combined cycle. We can't ignore that 36% difference compared to Megane.

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, Megane offers slightly better overall protection and takes the lead. From there things take a different direction, with Citroen being considerably quicker, thus putting more smile on driver's face. 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. 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. In case you have two minutes to spare I invite you to define your needs, desires and budget and see which car would be chosen by the virtual adviser™, among thousands of similar, yet so different vehicles.
