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 136hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 136hp 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 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 1% 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 with an average rating of 4.1, and models under the Renault badge with 4.2 out of 5. Some independent research have also placed C4 as average reliability-wise, and Megane is more or less at the same level.We should definitely mention that owners of cars with the same powertrain as Citroen C4 rank it on average as 4.2, while the one under the competitor's bonnet gets 3.6 out of 5.

Renault is a bit more agile, reaching 100km/h in 0.9 seconds less than its competitor. Still, it lacks the power to win the top speed competition, topping at 200 kilometers per hour, 7km/h less than the other car. When it comes to fuel economy things look pretty much the same for both cars, averaging around 7.9 liters of fuel per 100 kilometers (36 mpg), in combined cycle.

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. From there things take a different direction, with Renault offering somewhat better performance, just enough to call it quicker. 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. Nevertheless, let's not forget that people have different preferences and needs, so what really counts is your personal feel.
