Two significantly similar cars, no doubt about that. Still, each one has something different to offer. Having both cars powered by diesel engines and utilizing the 5-door wagon body style within the same 'Large family car' segment, the only major difference here really is their wheel drive configuration (front for the Alfa Romeo and rear in the case of the BMW). The first one has a FIAT-engineered powertrain under the hood, a 4-cylinder, 16-valves 140hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 136hp engine designed by BMW.

The fact that the BMW got tested by the European New Car Assessment Programme (Euro NCAP), while the other contender didn't, offers a slight advantage, as the 4-star rating is better than none. That aside, let's consider some other aspects which affect safety. 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 German car offers a marginal difference of 4% more metal.

I don't like generalizing things when it comes to reliability, although it does seem that BMW does have a slight advantage, all the models observed together. These are the results of an independent reasearch, while our visitors describe reliability of Alfa Romeo with an average rating of 4.2, and models under the BMW badge with 4.1 out of 5. The same official information place 156 as average reliability-wise, and 3 Series is more or less at the same level.That apart, owners of different cars powered by the same engine as the Italian car rank it on average as 3.6, while the one under the competitor's bonnet gets 4.4 out of 5.

Alfa Romeo is a bit more agile, reaching 100km/h in 0.2 seconds less than its competitor. Still, it lacks the power to win the top speed competition, topping at 203 kilometers per hour, 4km/h less than the other car. When it comes to fuel economy the winner has to be the German car, averaging around 5.9 liters of fuel per 100 kilometers (48 mpg), in combined cycle. We can't ignore that 15% difference compared to the Italian car.

BMW 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 German car beats the other contender by far, making it the best choice without even considering other things. When it comes to performance, both vehicles provide similar experience, so I wouldn't point any of them out. the German car , on the other hand, consumps significantly less fuel, and that's a big plus. All together, there's not much more to say, in this case I wouldn't even consider anything but BMW.
