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 120hp unit, while the other one gets its power and torque from a 4-cylinder, 8-valves 110hp 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. Still, apart from the official crash test results there are other things we need to be aware of. 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? On the other hand, when it comes to weight, a factor that most people underestimate, 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, at least on all of the models level. These are the official statistics, 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 4.3 out of 5, exactly the same as the other one.

Renault is a bit more agile, reaching 100km/h in 0.1 seconds less than its competitor. Still, it lacks the power to win the top speed competition, topping at 190 kilometers per hour, 7km/h less than the other car. When it comes to fuel economy the winner has to be Citroen C4, averaging around 3.6 liters of fuel per 100 kilometers (78 mpg), in combined cycle. We can't ignore that 22% 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. When it comes to performance, both vehicles provide similar experience, so I wouldn't point any of them out. Citroen C4 , on the other hand, consumps significantly less fuel, and that's a big plus. 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.
