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 diesel engine choice they offer. Both the engines are FIAT-engineered . The first one has a 4-cylinder, 16-valves 140hp unit, while the other one gets its power and torque from a 4-cylinder, 8-valves 110hp one.

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, when it comes to weight, a factor that most people underestimate, 156 offers a considerable difference of 11% more metal.

I don't like generalizing things when it comes to reliability, although it does seem that FIAT is significantly less fault-prone, at least on all of the models level. 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.Above it all, drivers of cars with the same engine as 156 rank it on average as 3.8, while the one under the competitor's bonnet gets 4.8 out of 5.

Alfa Romeo is undoubtly more agile, reaching 100km/h in 1.3 seconds less than its competitor. In addition to that it accelerates all the way to 203 kilometers per hour, 18km/h more than the other car. When it comes to fuel economy the winner has to be Marea, averaging around 5.6 liters of fuel per 100 kilometers (50 mpg), in combined cycle. We can't ignore that 20% difference compared to 156.

FIAT is apparently more reliable, not too much, but just enough. 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 being considerably quicker, thus putting more smile on driver's face. It does come at a cost though, and that's the fuel consumption... No mistake, whatever you decide here, but I'd still go for the FIAT. Nevertheless, let's not forget that people have different preferences and needs, so what really counts is your personal feel.
