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 144hp unit, while the other one gets its power and torque from a 4-cylinder, 8-valves 118hp 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 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, all the models observed together. That's the official data, while our visitors describe reliability of Alfa Romeo, as well as BMW, with the same average rating of 4.2 out of 5. Some independent research have also placed 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 4.8, while the one under the competitor's bonnet gets 3.3 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 210 kilometers per hour, 8km/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.

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. From there things take a different 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... It's not difficult to say then that if I'd need to make a choice, it would definitely be the 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.
