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 192hp unit, while the other one gets its power and torque from a 6-cylinder, 24-valves 510hp engine designed by Ferrari.

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. Moving further on, let's take a closer look at some additional safety-related facts. 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 considerable difference of 11% more metal.

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 results of an independent reasearch, 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. Some independent research have also placed 6 as average reliability-wise, and Giulia is more or less at the same level.We should definitely mention that owners of cars with the same powertrain 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.

Alfa Romeo is way more agile, reaching 100km/h in 3.9 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 an obvious choice would be the Japanese car, averaging around 6.3 liters of fuel per 100 kilometers (45 mpg), in combined cycle. That's 35% 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 offers significantly better overall protection, taking the lead here. 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... It's really tough to make a final decision here, but if I'd need to, I'd say Mazda. 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.
