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 120hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 103hp engine designed by FIAT.

Unfortunatelly, neither of the two vehicles was submitted to the European New Car Assessment Programme (Euro NCAP) testing. This makes it virtually impossible for me to pick one over the other and I'm generally against buying such cars as the safety should really always come first. 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 it doesn't do much to help us decide between the two. Furthermore, if we'd like to consider vehicle mass in this context too, which we definitely should, 156 offers a considerable difference of 10% more metal.

Reliability is not the best thing to consider on the make level, but it is worth mentioning that FIAT is significantly less fault-prone, when all the models are taken into account. These are the official statistics, while our visitors describe reliability of Alfa Romeo with an average rating of 4.2, and models under the FIAT badge with 4.3 out of 5. Some independent research have also placed 156 as average reliability-wise, and Marea is more or less at the same level.We should definitely mention that owners of cars with the same powertrain as 156 rank it on average as 4.6, while the one under the competitor's bonnet gets 4.2 out of 5.

Alfa Romeo is a bit more agile, reaching 100km/h in 0.2 seconds less than its competitor. In addition to that it accelerates all the way to 200 kilometers per hour, 13km/h more than the other car. When it comes to fuel economy things look pretty much the same for both cars, averaging around 8.3 liters of fuel per 100 kilometers (34 mpg), in combined cycle.

FIAT 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, 156 offers significantly better overall protection, taking the lead here. It all continues in the same direction, with Alfa Romeo offering somewhat better performance, just enough to call it quicker. To make things even better, it consumps less fuel! All together, there's not much more to say, in this case I wouldn't even consider anything but Alfa Romeo. 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.
