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 wagon 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 143hp 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. That aside, let's consider some other aspects which affect safety. Both vehicles belong to the large family car segment, which is generally a good thing safety-wise, but it doesn't do much to help us decide between the two. Furthermore, when it comes to weight, a factor that most people underestimate, the German car offers a considerable difference of 12% more metal.

Reliability is not the best thing to consider on the make level, but it is worth mentioning 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 4.1 out of 5. Independent research findings rank Insignia as average reliability-wise, and C5 is more or less at the same level.Above it all, drivers of cars with the same engine as the German car rank it on average as 1.0, while the one under the competitor's bonnet gets 3.9 out of 5.

Opel is way more agile, reaching 100km/h in 3.4 seconds less than its competitor. In addition to that it accelerates all the way to 242 kilometers per hour, 36km/h more than the other car. When it comes to fuel economy things look pretty much the same for both cars, averaging around 8.5 liters of fuel per 100 kilometers (33 mpg), in combined cycle.

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 outracing its opponent in any situation possible, making it better choice for boy racers. Fuel consumption is more or less the same. I believe that, when we take all into account, we have only one winner here - the Opel. 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.
