We are here considering two somewhat similar cars, but we can't deny some of the obvious differences. For a start, they are not even classified under the same segment, with the Opel being a micro car and the Citroen representing city car vehicle class. The first one has a Opel-engineered powertrain under the hood, a 4-cylinder, 16-valves 150hp unit, while the other one gets its power and torque from a 3-cylinder, 12-valves 110hp engine designed by Peugeot.

Both vehicles got tested by European New Car Assessment Programme (Euro NCAP), 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. The second vehicle is a city car and that gives it a marginal advantage over the micro car competitor, at least that's what statistics show. On the other hand, if we'd like to consider vehicle mass in this context too, which we definitely should, the German car offers a marginal difference of 2% more metal.

I don't like generalizing things when it comes to reliability, although it does seem that both brands display similar results in faults and breakdowns, at least on all of the models level. These are the results of an independent reasearch, while our visitors describe reliability of Opel with an average rating of 4.2, and models under the Citroen badge with 4.1 out of 5. Unfortunatelly, I don't have enough insight that would allow me to comment in more details on the specific models level. That apart, owners of different cars powered by the same engine as the German car rank it on average as 3.0, while the one under the competitor's bonnet gets 3.3 out of 5.

Opel is undoubtly more agile, reaching 100km/h in 1.1 seconds less than its competitor. In addition to that it accelerates all the way to 210 kilometers per hour, 20km/h more than the other car. When it comes to fuel economy the winner has to be the French car, averaging around 4.7 liters of fuel per 100 kilometers (60 mpg), in combined cycle. We can't ignore that 26% difference compared to the German 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 French car offers significantly better overall protection, taking the lead here. From there things take a different direction, with Opel 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 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.
