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 Renault-engineered powertrain under the hood, a 4-cylinder, 16-valves 220hp unit, while the other one gets its power and torque from a 3-cylinder, 12-valves 131hp engine designed by Peugeot.

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 Citroen being a slightly better choice apparently. Moving further on, let's take a closer look at some additional safety-related facts. Both vehicles belong to the small family car segment, which is generally classifying them somewhere in the middle safety-wise, but that fact doesn't break the tie between the two cars. Furthermore, if we'd like to consider vehicle mass in this context too, which we definitely should, Megane offers a considerable difference of 10% 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, at least on all of the models level. That's the official data, while our visitors describe reliability of Renault, as well as Citroen, with the same average rating of 4.1 out of 5. Independent research findings rank Megane as average reliability-wise, and C4 is more or less at the same level.That apart, owners of different cars powered by the same engine as Megane rank it on average as 3.0, while the one under the competitor's bonnet gets 4.0 out of 5.

Renault is way more agile, reaching 100km/h in 3.2 seconds less than its competitor. In addition to that it accelerates all the way to 240 kilometers per hour, 41km/h more than the other car. When it comes to fuel economy an obvious choice would be Citroen C4, averaging around 4.7 liters of fuel per 100 kilometers (60 mpg), in combined cycle. That's 55% 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 this case though, it seems that both cars show similar levels of passenger protection all together, so that won't break a tie. But one thing that actually could is the performance, with Renault 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... I believe that, when we take all into account, we have only one winner here - the Citroen. 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. Also, you could use the oportunity to find out which car, everything taken into account, would be the perfect choice for you in the eyes of the virtual adviser™, among thousands of similar, yet so different vehicles.
