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. Both the engines are Peugeot-engineered . The first one has a 4-cylinder, 16-valves 150hp unit, while the other one gets its power and torque from a 4-cylinder, 8-valves 115hp one.

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 that fact doesn't break the tie between the two cars. Furthermore, taking kerb weight as an important factor into account, Citroen C4 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 Peugeot 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 4.1, and models under the Peugeot badge with 4.3 out of 5. The same official information place C4 as average reliability-wise, and 308 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 4.6, while the one under the competitor's bonnet gets 4.2 out of 5.

Citroen is undoubtly more agile, reaching 100km/h in 2.8 seconds less than its competitor. In addition to that it accelerates all the way to 207 kilometers per hour, 17km/h more than the other car. When it comes to fuel economy the winner has to be 308, averaging around 4.2 liters of fuel per 100 kilometers (67 mpg), in combined cycle. We can't ignore that 17% difference compared to Citroen C4.

Peugeot 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. It does come at a cost though, and that's the fuel consumption... It's really tough to make a final decision here, but if I'd need to, I'd say Peugeot. 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.
