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 rear wheel drive system, it all comes up to the specific petrol engine choice they offer. The first one has a FIAT-engineered powertrain under the hood, a 4-cylinder, 16-valves 280hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 184hp 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. Still, apart from the official crash test results there are other things we need to be aware of. 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.

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 with an average rating of 4.2, and models under the BMW badge with 4.1 out of 5. The same official information place Giulia 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 4.5, while the one under the competitor's bonnet gets 3.5 out of 5.

Alfa Romeo is undoubtly more agile, reaching 100km/h in 1.7 seconds less than its competitor. In addition to that it accelerates all the way to 250 kilometers per hour, 15km/h more than the other car. When it comes to fuel economy an obvious choice would be the Italian car, averaging around 0 liters of fuel per 100 kilometers (0 mpg), in combined cycle. That's 100% difference compared to the German 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 this case though, it seems that both cars show similar levels of passenger protection all together, so that won't break a tie. But one thing that actually could is the performance, with Alfa Romeo outracing its opponent in any situation possible, making it better choice for boy racers. 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 Alfa Romeo. In any case that's my personal view, built upon all the data available to me. What should decide here though is the way you feel about the two vehicles, and I hope you'll find my guidelines useful in the process.
