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 FIAT-engineered powertrain under the hood, a 4-cylinder, 16-valves 140hp 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, still it doesn't help us solve our dilemma, does it? Furthermore, when it comes to weight, a factor that most people underestimate, Insignia offers a marginal difference of 3% 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. That's the official data, while our visitors describe reliability of Opel with an average rating of 4.2, and models under the BMW badge with 4.1 out of 5. Independent research findings rank Insignia as average reliability-wise, and 4 Series Gran Coupe is more or less at the same level.Above it all, drivers of cars with the same engine as Insignia rank it on average as 4.5, 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 1.3 seconds less than its competitor. In addition to that it accelerates all the way to 213 kilometers per hour, 8km/h more than the other car. When it comes to fuel economy the winner has to be Insignia, averaging around 3.7 liters of fuel per 100 kilometers (76 mpg), in combined cycle. We can't ignore that 22% 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 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... All together, there's not much more to say, in this case I wouldn't even consider anything but 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. 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™, out of 12.000+ vehicles we currently have in our database.
