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 Mercedes Benz-engineered powertrain under the hood, a 4-cylinder, 16-valves 122hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 120hp engine designed by Peugeot.

Both vehicles got tested by European New Car Assessment Programme (Euro NCAP), with the same number of safety stars gained in the process. 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 it doesn't do much to help us decide between the two. Furthermore, if we'd like to consider vehicle mass in this context too, which we definitely should, the German car offers a marginal difference of 8% more metal.

Manufacturers have been building their reliability reputation for decades now and, generally speaking, it appears that Citroen does have a slight advantage, all the models observed together. That's the official data, while our visitors describe reliability of Mercedes Benz with an average rating of 4.3, and models under the Citroen badge with 4.0 out of 5. The same official information place A as average reliability-wise, and DS4 is more or less at the same level.That apart, owners of different cars powered by the same engine as the German car rank it on average as 4.6, while the one under the competitor's bonnet gets 4.2 out of 5.

Mercedes Benz is way more agile, reaching 100km/h in 3 seconds less than its competitor. In addition to that it accelerates all the way to 202 kilometers per hour, 9km/h more than the other car. When it comes to fuel economy the winner has to be the German car, averaging around 5.5 liters of fuel per 100 kilometers (51 mpg), in combined cycle. We can't ignore that 13% difference compared to the French car.

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 my opinion, everything taken into account, the German car offers slightly better overall protection and takes the lead. It all continues in the same direction, with Mercedes Benz outracing its opponent in any situation possible, making it better choice for boy racers. To make things even better, it consumps less fuel! All together, there's not much more to say, in this case I wouldn't even consider anything but Mercedes Benz. 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.
