Virtual Adviser's™ opinion

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 diesel engine choice they offer. The first one has a Isuzu-engineered powertrain under the hood, a 4-cylinder, 16-valves 100hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 110hp engine designed by Peugeot.

Safety

Both vehicles got tested by European New Car Assessment Programme (Euro NCAP), with the Opel being a slightly better choice apparently. That aside, let's consider some other aspects which affect safety. Both vehicles belong to the small family car segment, which is generally classifying them somewhere in the middle safety-wise, but that fact doesn't break the tie between the two cars. Furthermore, taking kerb weight as an important factor into account, the German car offers a marginal difference of 1% more metal.

Reliability

Manufacturers have been building their reliability reputation for decades now and, generally speaking, it appears that Mazda does have a slight advantage, when all the models are taken into account. These are the results of an independent reasearch, 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. Independent research findings rank Astra as average reliability-wise, and 3 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 3.9, while the one under the competitor's bonnet gets 4.4 out of 5.

Performance & Fuel economy

Mazda is a bit more agile, reaching 100km/h in 0.8 seconds less than its competitor. In addition to that it accelerates all the way to 182 kilometers per hour, 1km/h more than the other car. When it comes to fuel economy things look pretty much the same for both cars, averaging around 5 liters of fuel per 100 kilometers (57 mpg), in combined cycle.


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. From there things take a different direction, with Mazda offering somewhat better performance, just enough to call it quicker. Fuel consumption is more or less the same. No mistake, whatever you decide here, but I'd still go for the Opel. Nevertheless, let's not forget that people have different preferences and needs, so what really counts is your personal feel. I'm only here to help. Also, you could use the oportunity to find out which car, everything taken into account, would be the perfect choice for you in the eyes of the virtual adviser, among thousands of similar, yet so different vehicles.
