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 218hp 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. Moving further on, let's take a closer look at some additional safety-related facts. Both vehicles belong to the small family car segment, which is generally classifying them somewhere in the middle 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 Japanese car offers a considerable difference of 17% 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, at least on all of the models level. 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. Independent research findings rank Impreza as average reliability-wise, and Astra is more or less at the same level.Above it all, drivers of cars with the same engine 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 3.3 seconds less than its competitor. In addition to that it accelerates all the way to 225 kilometers per hour, 22km/h more than the other car. When it comes to fuel economy the winner has to be the German car, averaging around 8.8 liters of fuel per 100 kilometers (32 mpg), in combined cycle. We can't ignore that 16% 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... No mistake, whatever you decide here, but I'd still go for the 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. Also, you could use the oportunity to find out which car, everything taken into account, would be the perfect choice for you in the eyes of the virtual adviser™, among thousands of similar, yet so different vehicles.
