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 80hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 110hp engine designed by Peugeot.

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. Still, apart from the official crash test results there are other things we need to be aware of. 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, all the models observed together. 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. Independent research findings rank Astra as average reliability-wise, and 3 is more or less at the same level.That apart, owners of different cars powered by the same engine as the German car rank it on average as 4.1, while the one under the competitor's bonnet gets 4.4 out of 5.

Performance & Fuel economy

Mazda is way more agile, reaching 100km/h in 3.5 seconds less than its competitor. In addition to that it accelerates all the way to 182 kilometers per hour, 14km/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 outracing its opponent in any situation possible, making it better choice for boy racers. 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 Opel. In any case that's my personal view, built upon all the data available to me. What should decide here though is the way you feel about the two vehicles, and I hope you'll find my guidelines useful in the process. 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.
