Two significantly similar cars, no doubt about that. Still, each one has something different to offer. Having both cars powered by petrol engines and utilizing the 5-door hatchback body style within the same 'Large family car' segment, the only major difference here really is their wheel drive configuration (4 x 4 for the Opel and front in the case of the Citroen). The first one has a Opel-engineered powertrain under the hood, a 4-cylinder, 16-valves 250hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 200hp engine designed by Peugeot.

A starting point here would be to take a look at the results from European New Car Assessment Programme (Euro NCAP) tests which were performed on both of the cars, 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 large family car segment, which is generally a good thing 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, the German car offers a considerable difference of 16% 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 official statistics, 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. The same official information place Insignia as average reliability-wise, and DS5 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 1.0, while the one under the competitor's bonnet gets 4.0 out of 5.

Opel is a bit more agile, reaching 100km/h in 0.7 seconds less than its competitor. In addition to that it accelerates all the way to 250 kilometers per hour, 15km/h more than the other car. When it comes to fuel economy the winner has to be the French car, averaging around 6.7 liters of fuel per 100 kilometers (42 mpg), in combined cycle. We can't ignore that 16% difference compared to the German car.

Citroen is apparently more reliable, not too much, but just enough. 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 significantly better overall protection, taking the lead here. It all continues in the same direction, with Opel offering somewhat better performance, just enough to call it quicker. It does come at a cost though, and that's the fuel consumption... I believe that, when we take all into account, we have only one winner here - the Citroen. 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.
