Virtual Adviser's™ opinion
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 '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 95hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 100hp engine designed by Opel.
SafetyThe 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. Still, apart from the official crash test results there are other things we need to be aware of. 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, taking kerb weight as an important factor into account, the Japanese car offers a considerable difference of 13% more metal.
ReliabilityReliability 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, all the models observed together. These are the results of an independent reasearch, while our visitors describe reliability of Subaru, as well as Opel, with the same average rating of 4.2 out of 5. Independent research findings rank 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 4.5, while the one under the competitor's bonnet gets 4.2 out of 5.
Performance & Fuel economyOpel is a bit more agile, reaching 100km/h in 0.8 seconds less than its competitor. In addition to that it accelerates all the way to 183 kilometers per hour, 14km/h more than the other car. When it comes to fuel economy the winner has to be the German car, averaging around 7.7 liters of fuel per 100 kilometers (37 mpg), in combined cycle. We can't ignore that 16% difference compared to the Japanese car.
Verdict
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 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. To make things even better, it consumps less fuel! All together, there's not much more to say, in this case I wouldn't even consider anything but 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 more than 12.000 different ones in our database.
