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 136hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 110hp one.

Both vehicles got tested by European New Car Assessment Programme (Euro NCAP), with the Citroen being a slightly better choice apparently. 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, when it comes to weight, a factor that most people underestimate, 307 offers a marginal difference of 7% more metal.

I don't like generalizing things when it comes to reliability, although it does seem 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 Peugeot with an average rating of 4.3, and models under the Citroen badge with 4.0 out of 5. The same official information place 307 as average reliability-wise, and C4 is more or less at the same level.Above it all, drivers of cars with the same engine as 307 rank it on average as 4.3, while the one under the competitor's bonnet gets 4.4 out of 5.

Peugeot is undoubtly more agile, reaching 100km/h in 2.6 seconds less than its competitor. In addition to that it accelerates all the way to 202 kilometers per hour, 10km/h more than the other car. When it comes to fuel economy the winner has to be Citroen C4, averaging around 4.7 liters of fuel per 100 kilometers (60 mpg), in combined cycle. We can't ignore that 15% difference compared to 307.

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. From there things take a different direction, with Peugeot 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... It's really tough to make a final decision here, but if I'd need to, I'd say 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. 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.
