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 140hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 120hp engine designed by Mazda.

Safety

Both vehicles got tested by European New Car Assessment Programme (Euro NCAP), with the Alfa Romeo being a slightly better choice apparently. That aside, let's consider some other aspects which affect safety. Both vehicles belong to the large family car segment, which is generally a good thing 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 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, when all the models are taken into account. These are the official statistics, while our visitors describe reliability of Alfa Romeo with an average rating of 4.2, and models under the Mazda badge with 4.5 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 a bit more agile, reaching 100km/h in 0.5 seconds less than its competitor. In addition to that it accelerates all the way to 206 kilometers per hour, 9km/h more than the other car. When it comes to fuel economy things look pretty much the same for both cars, averaging around 7.7 liters of fuel per 100 kilometers (37 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 offering somewhat better performance, just enough to call it quicker. Fuel consumption is more or less the same. 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. 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, among more than 12.000 different ones in our database.
