Well, these are two pretty similar cars we have here! It's only details that could potentially make the difference. Considering they both belong to the mpv segment and utilize the same 5-door MPV body style and the front wheel drive system, it all comes up to the specific petrol engine choice they offer. The first one has a Mazda-engineered powertrain under the hood, a 4-cylinder, 16-valves 115hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 170hp engine designed by Opel.

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. That aside, let's consider some other aspects which affect safety. Both vehicles belong to the mpv segment, which is generally a good thing safety-wise, but that fact doesn't break the tie between the two cars. On the other hand, taking kerb weight as an important factor into account, the German car offers a considerable difference of 14% more metal.

I don't like generalizing things when it comes to reliability, although it does seem that Mazda does have a slight advantage, all the models observed together. These are the results of an independent reasearch, while our visitors describe reliability of Mazda with an average rating of 4.4, and models under the Opel badge with 4.2 out of 5. The same official information place 5 as average reliability-wise, and Zafira is more or less at the same level.We should definitely mention that owners of cars with the same powertrain as the Japanese car rank it on average as 4.0, while the one under the competitor's bonnet gets 3.0 out of 5.

Opel is way more agile, reaching 100km/h in 3.6 seconds less than its competitor. In addition to that it accelerates all the way to 212 kilometers per hour, 30km/h more than the other car. When it comes to fuel economy the winner has to be the German car, averaging around 6.6 liters of fuel per 100 kilometers (43 mpg), in combined cycle. We can't ignore that 9% difference compared to the Japanese car.

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 significantly better overall protection, taking the lead here. It all continues in the same direction, with Opel outracing its opponent in any situation possible, making it better choice for boy racers. 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 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. 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.
