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 185hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 166hp 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. 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. Furthermore, when it comes to weight, a factor that most people underestimate, the Italian car offers a considerable difference of 10% 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. 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. The same official information place 159 as average reliability-wise, and 6 is more or less at the same level.We should definitely mention that owners of cars with the same powertrain as the Italian car rank it on average as 4.5, while the one under the competitor's bonnet gets 3.0 out of 5.

Performance & Fuel economy

Alfa Romeo is a bit more agile, reaching 100km/h in 0.1 seconds less than its competitor. In addition to that it accelerates all the way to 222 kilometers per hour, 8km/h more than the other car. When it comes to fuel economy the winner has to be the Japanese car, averaging around 8.7 liters of fuel per 100 kilometers (32 mpg), in combined cycle. We can't ignore that 8% 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 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. 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 Alfa Romeo. 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. 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.
