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 petrol engines and utilizing the 4-door sedan body style within the same 'Large family car' segment, the only major difference here really is their wheel drive configuration (4 x 4 for the Opel and front in the case of the Mazda). The first one has a Opel-engineered powertrain under the hood, a 4-cylinder, 16-valves 250hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 165hp engine designed by Mazda.
SafetyThe first thing to look into here would be the results from European New Car Assessment Programme (Euro NCAP) tests performed on the two cars. Good thing is that both vehicles got tested, 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 large family car segment, which is generally a good thing safety-wise, but that fact doesn't break the tie between the two cars. Furthermore, if we'd like to consider vehicle mass in this context too, which we definitely should, the German car offers a considerable difference of 27% more metal.
ReliabilityI don't like generalizing things when it comes to reliability, although it does seem that Mazda does have a slight advantage, when all the models are taken into account. That's the official data, while our visitors describe reliability of Opel with an average rating of 4.2, and models under the Mazda badge with 4.4 out of 5. The same official information place Insignia as average reliability-wise, and 6 is more or less at the same level.We should definitely mention that owners of cars with the same powertrain as the German car rank it on average as 1.0, while the one under the competitor's bonnet gets 5.0 out of 5.
Performance & Fuel economyOpel is undoubtly more agile, reaching 100km/h in 1.6 seconds less than its competitor. In addition to that it accelerates all the way to 250 kilometers per hour, 34km/h more than the other car. When it comes to fuel economy the winner has to be the Japanese car, averaging around 5.9 liters of fuel per 100 kilometers (48 mpg), in combined cycle. We can't ignore that 32% difference compared to the German car.
Verdict
Mazda 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, the German car offers significantly better overall protection, taking the lead here. It all continues in the same direction, with Opel being considerably quicker, thus putting more smile on driver's face. It does come at a cost though, and that's the fuel consumption... I believe that, when we take all into account, we have only one winner here - the Mazda. 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. In case you have two minutes to spare I invite you to define your needs, desires and budget and see which car would be chosen by the virtual adviser™, among thousands of similar, yet so different vehicles.
