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 General Motors-engineered powertrain under the hood, a 3-cylinder, 12-valves 115hp 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. Furthermore, when it comes to weight, a factor that most people underestimate, the French car offers a marginal difference of 1% 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. That's the official data, while our visitors describe reliability of Opel with an average rating of 4.2, and models under the Citroen badge with 4.0 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 4.5, while the one under the competitor's bonnet gets 3.0 out of 5.

Citroen is a bit more agile, reaching 100km/h in 0.3 seconds less than its competitor. Still, it lacks the power to win the top speed competition, topping at 190 kilometers per hour, 6km/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.

Opel 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 beats the other contender by far, making it the best choice without even considering other things. When it comes to performance, both vehicles provide similar experience, so I wouldn't point any of them out. the French car still consumps less fuel, which needs to be taken into consideration. All together, there's not much more to say, in this case I wouldn't even consider anything but 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. I suggest you spend two more minutes in order to find out which car, based on your needs and budget, would be picked by the virtual adviser™, among thousands of similar, yet so different vehicles.
