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 6-cylinder, 24-valves 192hp unit, while the other one gets its power and torque from a 6-cylinder, 24-valves 192hp 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 it doesn't do much to help us decide between the two. On the other hand, if we'd like to consider vehicle mass in this context too, which we definitely should, the German car offers a marginal difference of 7% more metal.

Manufacturers have been building their reliability reputation for decades now and, generally speaking, it appears that BMW does have a slight advantage, at least on all of the models level. That's the official data, 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.We should definitely mention that owners of cars with the same powertrain as the Italian car rank it on average as 5.0, while the one under the competitor's bonnet gets 2.8 out of 5.

Both of the cars accelerate exactly the same, so we couldn't put one above the other. Car No. 2 is faster though, reaching top speed of 237 kilometers per hour, 7km/h more than the other car. When it comes to fuel economy an obvious choice would be the German car, averaging around 9.2 liters of fuel per 100 kilometers (31 mpg), in combined cycle. That's 27% difference compared to the Italian car!

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 German 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 BMW 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 BMW. Anyway, that's the most objective conclusion I could've came up with and it's based solely on the information found on this website. Aspects such as design, practicality, brand value and driving experience are there for you to measure them out. Also, you could use the oportunity to find out which car, everything taken into account, would be the perfect choice for you in the eyes of the virtual adviser™, among thousands of similar, yet so different vehicles.
