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 (front for the Mazda and rear in the case of the Alfa Romeo). The first one has a Mazda-engineered powertrain under the hood, a 4-cylinder, 16-valves 194hp unit, while the other one gets its power and torque from a 6-cylinder, 24-valves 510hp engine designed by Ferrari.

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 same number of safety stars gained in the process. 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. On the other hand, when it comes to weight, a factor that most people underestimate, the Italian car offers a marginal difference of 8% 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, when all the models are taken into account. 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. Unfortunatelly, I don't have enough insight that would allow me to comment in more details on the specific models level. That apart, owners of different cars powered by the same engine as the Japanese car rank it on average as 3.0, while the one under the competitor's bonnet gets 5.0 out of 5.

Performance & Fuel economy

Alfa Romeo is way more agile, reaching 100km/h in 4.2 seconds less than its competitor. In addition to that it accelerates all the way to 307 kilometers per hour, 84km/h more than the other car. When it comes to fuel economy the winner has to be the Japanese car, averaging around 6.7 liters of fuel per 100 kilometers (42 mpg), in combined cycle. We can't ignore that 27% difference compared to the Italian car.


Verdict

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 offers slightly better overall protection and takes the lead. It all continues in the same direction, with Alfa Romeo 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... 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. 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. 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.
