Overview

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 small family car segment and utilize the same 5-door hatchback 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 84hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 90hp engine designed by Opel.

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 Opel being a slightly better choice apparently. Moving further on, let's take a closer look at some additional safety-related facts. Both vehicles belong to the small family car segment, which is generally classifying them somewhere in the middle safety-wise, but it doesn't do much to help us decide between the two. Furthermore, when it comes to weight, a factor that most people underestimate, the Japanese car offers a marginal difference of 2% 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. These are the official statistics, 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. Some independent research have also placed 3 as average reliability-wise, and Astra 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 4.9, while the one under the competitor's bonnet gets 4.1 out of 5.

Performance & Fuel economy

Opel is a bit more agile, reaching 100km/h in 0.6 seconds less than its competitor. In addition to that it accelerates all the way to 178 kilometers per hour, 9km/h more than the other car. When it comes to fuel economy the winner has to be the German car, averaging around 6.3 liters of fuel per 100 kilometers (45 mpg), in combined cycle. We can't ignore that 13% difference compared to the Japanese 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 slightly better overall protection and takes the lead. It all continues in the same direction, with Opel being considerably quicker, thus putting more smile on driver's face. 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.
