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 5-door wagon 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 140hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 136hp engine designed by FIAT.

Both vehicles got tested by European New Car Assessment Programme (Euro NCAP), with the Alfa Romeo being a slightly better choice apparently. 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, still it doesn't help us solve our dilemma, does it? On the other hand, if we'd like to consider vehicle mass in this context too, which we definitely should, the Italian car offers a marginal difference of 2% more metal.

I don't like generalizing things when it comes to reliability, although it does seem that Audi does have a slight advantage, at least on all of the models level. 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. Independent research findings rank A4 as average reliability-wise, and 159 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 4.5 out of 5.

Audi is a bit more agile, reaching 100km/h in 0.2 seconds less than its competitor. In addition to that it accelerates all the way to 207 kilometers per hour, 7km/h more than the other car. When it comes to fuel economy things look pretty much the same for both cars, averaging around 5.5 liters of fuel per 100 kilometers (51 mpg), in combined cycle.

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 Italian car offers much better overall protection, which launches it ahead of the other contender. From there things take a different direction, with Audi offering somewhat better performance, just enough to call it quicker. 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 Alfa Romeo. 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™, out of 12.000+ vehicles we currently have in our database.
