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 small family car segment and utilize the same 3-door hatchback body style and the front wheel drive system, it all comes up to the specific diesel engine choice they offer. The first one has a Volkswagen-engineered powertrain under the hood, a 4-cylinder, 8-valves 105hp unit, while the other one gets its power and torque from a 4-cylinder, 8-valves 115hp engine designed by FIAT.

Both vehicles got tested by European New Car Assessment Programme (Euro NCAP), with the Audi being a slightly better choice apparently. That aside, let's consider some other aspects which affect safety. Both vehicles belong to the small family car segment, which is generally classifying them somewhere in the middle safety-wise, still it doesn't help us solve our dilemma, does it? Furthermore, when it comes to weight, a factor that most people underestimate, the German car offers a marginal difference of 4% more metal.

Manufacturers have been building their reliability reputation for decades now and, generally speaking, it appears that Audi does have a slight advantage, all the models observed together. That's the official data, while our visitors describe reliability of Audi, as well as Alfa Romeo, with the same average rating of 4.2 out of 5. Some independent research have also placed A3 as average reliability-wise, and 147 is more or less at the same level.We should definitely mention that owners of cars with the same powertrain as the German car rank it on average as 4.4, while the one under the competitor's bonnet gets 4.0 out of 5.

Alfa Romeo is undoubtly more agile, reaching 100km/h in 1.5 seconds less than its competitor. In addition to that it accelerates all the way to 191 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 4.9 liters of fuel per 100 kilometers (58 mpg), in combined cycle. We can't ignore that 18% difference compared to the Italian car.

Audi 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 offers much better overall protection, which launches it ahead of the other contender. 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... All together, there's not much more to say, in this case I wouldn't even consider anything but Audi. 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. 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.
