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 'Large family car' segment, the only major difference here really is their wheel drive configuration (front for the Opel and rear in the case of the BMW). The first one has a General Motors-engineered powertrain under the hood, a 4-cylinder, 16-valves 136hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 143hp engine designed by BMW.
SafetyThe fact that the Opel got tested by the European New Car Assessment Programme (Euro NCAP), while the other contender didn't, puts it sky-high safety-wise, in my eyes at least. That aside, let's consider some other aspects which affect safety. Both vehicles belong to the large family car segment, which is generally a good thing safety-wise, but it doesn't do much to help us decide between the two. Furthermore, if we'd like to consider vehicle mass in this context too, which we definitely should, Insignia offers a marginal difference of 2% more metal.
ReliabilityReliability is not the best thing to consider on the make level, but it is worth mentioning that Opel does have a slight advantage, all the models observed together. These are the results of an independent reasearch, while our visitors describe reliability of Opel, as well as BMW, with the same average rating of 4.2 out of 5. Some independent research have also placed Insignia as average reliability-wise, and 4 Series Gran Coupe is more or less at the same level.We should definitely mention that owners of cars with the same powertrain as Insignia rank it on average as 3.8, while the one under the competitor's bonnet gets 4.1 out of 5.
Performance & Fuel economyBMW is undoubtly more agile, reaching 100km/h in 1.7 seconds less than its competitor. In addition to that it accelerates all the way to 213 kilometers per hour, 3km/h more than the other car. When it comes to fuel economy the winner has to be Insignia, averaging around 3.9 liters of fuel per 100 kilometers (72 mpg), in combined cycle. We can't ignore that 15% difference compared to 4 Series Gran Coupe.
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, Insignia beats the other contender by far, making it the best choice without even considering other things. From there things take a different direction, with BMW being considerably quicker, thus putting more smile on driver's face. 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. 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.
