Virtual Adviser's™ opinion

Overview

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 5-door wagon 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 6-cylinder, 24-valves 325hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 170hp engine designed by Mazda.

Safety

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 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, taking kerb weight as an important factor into account, the German car offers a potentially life-saving difference of 33% more metal.

Reliability

Reliability is not the best thing to consider on the make level, but it is worth mentioning 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 5.0 out of 5, exactly the same as the other one.

Performance & Fuel economy

Opel is undoubtly more agile, reaching 100km/h in 2.1 seconds less than its competitor. In addition to that it accelerates all the way to 250 kilometers per hour, 32km/h more than the other car. When it comes to fuel economy an obvious choice would be the Japanese car, averaging around 8.1 liters of fuel per 100 kilometers (35 mpg), in combined cycle. That's 35% difference compared to the German car!


Verdict

Mazda 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, the German car offers much better overall protection, which launches it ahead of the other contender. 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... No mistake, whatever you decide here, but I'd still go for 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. 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.
