Virtual Adviser's™ opinion

Overview

Two significantly similar cars, no doubt about that. Still, each one has something different to offer. Having both cars powered by petrol engines and utilizing the 4-door sedan body style within the same 'Large family car' segment, the only major difference here really is their wheel drive configuration (4 x 4 for the Mazda and front in the case of the Alfa Romeo). The first one has a Mazda-engineered powertrain under the hood, a 4-cylinder, 16-valves 260hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 185hp engine designed by Alfa Romeo.

Safety

The first thing to look into here would be the results from European New Car Assessment Programme (Euro NCAP) tests performed on the two cars. Good thing is that both vehicles got tested, 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, but that fact doesn't break the tie between the two cars. Furthermore, if we'd like to consider vehicle mass in this context too, which we definitely should, the Japanese car offers a marginal difference of 7% more metal.

Reliability

Manufacturers have been building their reliability reputation for decades now and, generally speaking, it appears that Mazda is significantly less fault-prone, all the models observed together. These are the official statistics, while our visitors describe reliability of Mazda with an average rating of 4.4, and models under the Alfa Romeo badge with 4.2 out of 5. The same official information place 6 as average reliability-wise, and 159 is more or less at the same level.That apart, owners of different cars powered by the same engine as the Japanese car rank it on average as 4.7, while the one under the competitor's bonnet gets 4.8 out of 5.

Performance & Fuel economy

Mazda is undoubtly more agile, reaching 100km/h in 2.2 seconds less than its competitor. In addition to that it accelerates all the way to 240 kilometers per hour, 18km/h more than the other car. When it comes to fuel economy the winner has to be the Italian car, averaging around 9.4 liters of fuel per 100 kilometers (30 mpg), in combined cycle. We can't ignore that 9% 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 Italian car offers slightly better overall protection and takes the lead. From there things take a different direction, with Mazda 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. 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. 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.
