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 4-door sedan body style within the same 'Small 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 265hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 136hp engine designed by Opel.

The fact that the Opel got tested by the European New Car Assessment Programme (Euro NCAP), while the other contender didn't, offers a slight advantage, as the 4-star rating is better than none. That aside, let's consider some other aspects which affect safety. Both vehicles belong to the small family car segment, which is generally classifying them somewhere in the middle safety-wise, but that fact doesn't break the tie between the two cars. Furthermore, if we'd like to consider vehicle mass in this context too, which we definitely should, the Japanese car offers a considerable difference of 26% more metal.

Manufacturers have been building their reliability reputation for decades now and, generally speaking, it appears that both brands display similar results in faults and breakdowns, all the models observed together. That's the official data, 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 Impreza as average reliability-wise, and Astra 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 3.0, while the one under the competitor's bonnet gets 5.0 out of 5.

Subaru is way more agile, reaching 100km/h in 3.5 seconds less than its competitor. In addition to that it accelerates all the way to 238 kilometers per hour, 30km/h more than the other car. When it comes to fuel economy an obvious choice would be the German car, averaging around 8.6 liters of fuel per 100 kilometers (33 mpg), in combined cycle. That's 41% difference compared to the Japanese car!

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 German car offers significantly better overall protection, taking the lead here. From there things take a different direction, with Subaru outracing its opponent in any situation possible, making it better choice for boy racers. It does come at a cost though, and that's the fuel consumption... All together, there's not much more to say, in this case I wouldn't even consider anything but Opel. Anyway, that's the most objective conclusion I could've came up with and it's based solely on the information found on this website. Aspects such as design, practicality, brand value and driving experience are there for you to measure them out.
