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 3-door hatchback body style within the same 'Small family car' segment, the only major difference here really is their wheel drive configuration (rear for the BMW and front in the case of the Opel). The first one has a BMW-engineered powertrain under the hood, a 4-cylinder, 16-valves 143hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 240hp engine designed by Opel.

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 small family car segment, which is generally classifying them somewhere in the middle safety-wise, still it doesn't help us solve our dilemma, does it? On the other hand, when it comes to weight, a factor that most people underestimate, Astra offers a marginal difference of 4% more metal.

I don't like generalizing things when it comes to reliability, although it does seem that Opel does have a slight advantage, at least on all of the models level. These are the official statistics, while our visitors describe reliability of BMW with an average rating of 4.1, and models under the Opel badge with 4.2 out of 5. The same official information place 1 Series as average reliability-wise, and Astra is more or less at the same level.That apart, owners of different cars powered by the same engine as 1 Series rank it on average as 3.0, while the one under the competitor's bonnet gets 5.0 out of 5.

Opel is undoubtly more agile, reaching 100km/h in 2.3 seconds less than its competitor. In addition to that it accelerates all the way to 244 kilometers per hour, 34km/h more than the other car. When it comes to fuel economy an obvious choice would be 1 Series, averaging around 6.1 liters of fuel per 100 kilometers (46 mpg), in combined cycle. That's 51% difference compared to Astra!

Opel 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, Astra offers slightly better overall protection and takes the lead. It all continues in the same direction, with Opel 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... It's really tough to make a final decision here, but if I'd need to, I'd say 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.
