Two significantly similar cars, no doubt about that. Still, each one has something different to offer. Having both cars powered by diesel engines and utilizing the 4-door sedan 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 Subaru and front in the case of the Opel). The first one has a Subaru-engineered powertrain under the hood, a 4-cylinder, 16-valves 150hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 140hp engine designed by FIAT.

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. Still, apart from the official crash test results there are other things we need to be aware of. 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. On the other hand, when it comes to weight, a factor that most people underestimate, the German car offers a marginal difference of 1% 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, when all the models are taken into account. These are the official statistics, while our visitors describe reliability of Subaru, as well as Opel, with the same average rating of 4.2 out of 5. Some independent research have also placed Legacy as average reliability-wise, and Insignia is more or less at the same level.We should definitely mention that owners of cars with the same powertrain as the Japanese car rank it on average as 4.7, while the one under the competitor's bonnet gets 4.5 out of 5.

Subaru is undoubtly more agile, reaching 100km/h in 1.2 seconds less than its competitor. In addition to that it accelerates all the way to 206 kilometers per hour, 1km/h more than the other car. When it comes to fuel economy the winner has to be the German car, averaging around 3.7 liters of fuel per 100 kilometers (76 mpg), in combined cycle. We can't ignore that 49% difference compared to the Japanese car.

Subaru 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. From there things take a different direction, with Subaru being considerably quicker, thus putting more smile on driver's face. 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 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. 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.
