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 large family car segment and utilize the same 4-door sedan 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 Alfa Romeo-engineered powertrain under the hood, a 4-cylinder, 16-valves 200hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 120hp 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 Alfa Romeo 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 large family car segment, which is generally a good thing safety-wise, still it doesn't help us solve our dilemma, does it? Furthermore, if we'd like to consider vehicle mass in this context too, which we definitely should, the Italian car offers a considerable difference of 10% more metal.

Reliability

Reliability is not the best thing to consider on the make level, but it is worth mentioning that Mazda is significantly less fault-prone, at least on all of the models level. That's the official data, while our visitors describe reliability of Alfa Romeo with an average rating of 4.2, and models under the Mazda badge with 4.4 out of 5. The same official information place 159 as average reliability-wise, and 6 is more or less at the same level.Above it all, drivers of cars with the same engine as the Italian car rank it on average as 3.5, while the one under the competitor's bonnet gets 5.0 out of 5.

Performance & Fuel economy

Alfa Romeo is undoubtly more agile, reaching 100km/h in 3 seconds less than its competitor. In addition to that it accelerates all the way to 235 kilometers per hour, 38km/h more than the other car. When it comes to fuel economy things look pretty much the same for both cars, averaging around 7.9 liters of fuel per 100 kilometers (36 mpg), in combined cycle.


Verdict

Mazda is apparently more reliable, not too much, but just enough. 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 Italian car beats the other contender by far, making it the best choice without even considering other things. It all continues in the same direction, with Alfa Romeo being considerably quicker, thus putting more smile on driver's face. It does come at a cost though, and that's the fuel consumption... I believe that, when we take all into account, we have only one winner here - the Alfa Romeo. 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. 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 more than 12.000 different ones in our database.
