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 petrol engine choice they offer. The first one has a Peugeot-engineered powertrain under the hood, a 4-cylinder, 16-valves 156hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 112hp 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 small family car segment, which is generally classifying them somewhere in the middle safety-wise, still it doesn't help us solve our dilemma, does it? Furthermore, taking kerb weight as an important factor into account, Citroen C4 offers a marginal difference of 5% 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. These are the official statistics, 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 C4 as average reliability-wise, and Megane is more or less at the same level.Above it all, drivers of cars with the same engine as Citroen C4 rank it on average as 4.4, while the one under the competitor's bonnet gets 3.9 out of 5.

Citroen is undoubtly more agile, reaching 100km/h in 1.8 seconds less than its competitor. In addition to that it accelerates all the way to 214 kilometers per hour, 19km/h more than the other car. When it comes to fuel economy the winner has to be Citroen C4, averaging around 6.3 liters of fuel per 100 kilometers (45 mpg), in combined cycle. We can't ignore that 10% difference compared to Megane.

Citroen 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 C4 offers slightly better overall protection and takes the lead. It all continues in the same 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. Nevertheless, let's not forget that people have different preferences and needs, so what really counts is your personal feel. I'm only here to help.
