Virtual Adviser's™ opinion


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 5-door wagon 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 Alfa Romeo and front in the case of the Mazda). The first one has a Alfa Romeo-engineered powertrain under the hood, a 6-cylinder, 24-valves 260hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 166hp engine designed by Mazda.


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 it doesn't do much to help us decide between the two. Furthermore, when it comes to weight, a factor that most people underestimate, the Italian car offers a considerable difference of 13% more metal.


Manufacturers have been building their reliability reputation for decades now and, generally speaking, it appears that Mazda is significantly less fault-prone, when all the models are taken into account. 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. Some independent research have also placed 159 as average reliability-wise, and 6 is more or less at the same level.That apart, owners of different cars powered by the same engine as the Italian car rank it on average as 5.0, while the one under the competitor's bonnet gets 3.0 out of 5.

Performance & Fuel economy

Alfa Romeo is undoubtly more agile, reaching 100km/h in 2 seconds less than its competitor. In addition to that it accelerates all the way to 248 kilometers per hour, 39km/h more than the other car. When it comes to fuel economy an obvious choice would be the Japanese car, averaging around 8.8 liters of fuel per 100 kilometers (32 mpg), in combined cycle. That's 26% difference compared to the Italian car!


Alfa Romeo 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 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... At the end, as much as I'd like to give you a winner here, it's simply a pure tie if you ask me. 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 thousands of similar, yet so different vehicles.
