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 diesel engines and utilizing the 5-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 116hp unit, while the other one gets its power and torque from a 4-cylinder, 8-valves 120hp engine designed by FIAT.
SafetyA 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. 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, still it doesn't help us solve our dilemma, does it? Furthermore, taking kerb weight as an important factor into account, 1 Series offers a marginal difference of 1% more metal.
ReliabilityManufacturers have been building their reliability reputation for decades now and, generally speaking, it appears that Opel does have a slight advantage, at least on all of the models level. That's the official data, while our visitors describe reliability of BMW, as well as Opel, with the same average rating of 4.2 out of 5. Independent research findings rank 1 Series 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 1 Series rank it on average as 4.5 out of 5, exactly the same as the other one.
Performance & Fuel economyBMW is a bit more agile, reaching 100km/h in 0.3 seconds less than its competitor. In addition to that it accelerates all the way to 200 kilometers per hour, 5km/h more than the other car. When it comes to fuel economy the winner has to be 1 Series, averaging around 4.4 liters of fuel per 100 kilometers (64 mpg), in combined cycle. We can't ignore that 18% difference compared to Astra.
Verdict
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, 1 Series offers slightly better overall protection and takes the lead. It all continues in the same direction, with BMW 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 BMW. In any case that's my personal view, built upon all the data available to me. What should decide here though is the way you feel about the two vehicles, and I hope you'll find my guidelines useful in the process.
