Well, these are two pretty similar cars we have here! It's only details that could potentially make the difference. Not only that they both belong to the small family car segment and utilize the same 5-door hatchback body style, they are even powered by the same Peugeot-developed diesel engine! There is not much there to point us towards one vehicle or the other. Or is it?

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. 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, taking kerb weight as an important factor into account, Citroen C4 offers a marginal difference of 1% 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. These are the results of an independent reasearch, while our visitors describe reliability of Peugeot with an average rating of 4.3, and models under the Citroen badge with 4.1 out of 5. Some independent research have also placed 307 7% above average, and C4 2% below the first one. Above it all, drivers of cars with the same engine as these two vehicles rank it on average as 4.4 out of 5.

Peugeot is undoubtly more agile, reaching 100km/h in 1.2 seconds less than its competitor. Still, it lacks the power to win the top speed competition, topping at 188 kilometers per hour, 4km/h less than the other car. When it comes to fuel economy things look pretty much the same for both cars, averaging around 4.8 liters of fuel per 100 kilometers (59 mpg), in combined cycle.

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 much better overall protection, which launches it ahead of the other contender. From there things take a different direction, with Peugeot offering somewhat better performance, just enough to call it quicker. It does come at a cost though, and that's the fuel consumption... It's not difficult to say then that if I'd need to make a choice, it would definitely be the 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.
