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 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 Alfa Romeo-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 143hp engine designed by BMW.

Both vehicles got tested by European New Car Assessment Programme (Euro NCAP), with the same number of safety stars gained in the process. 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 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, the Italian car offers a marginal difference of 1% more metal.

I don't like generalizing things when it comes to reliability, although it does seem that BMW does have a slight advantage, when all the models are taken into account. 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. Some independent research have also placed 159 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 3.5, while the one under the competitor's bonnet gets 3.0 out of 5.

BMW is a bit more agile, reaching 100km/h in 0.9 seconds less than its competitor. In addition to that it accelerates all the way to 210 kilometers per hour, 4km/h more than the other car. When it comes to fuel economy the winner has to be the German car, averaging around 6 liters of fuel per 100 kilometers (47 mpg), in combined cycle. We can't ignore that 30% 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 Italian car offers slightly better overall protection and takes the lead. From there things take a different direction, with BMW being considerably quicker, thus putting more smile on driver's face. 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 BMW. 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. In case you have two minutes to spare I invite you to define your needs, desires and budget and see which car would be chosen by the virtual adviser™, among thousands of similar, yet so different vehicles.
