Virtual Adviser's™ opinion
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 front wheel drive system, it all comes up to the specific diesel engine choice they offer. The first one has a FIAT-engineered powertrain under the hood, a 4-cylinder, 16-valves 136hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 140hp engine designed by Volkswagen.Safety
A starting point here would be to take a look at the results from European New Car Assessment Programme (Euro NCAP) tests which were performed on both of the cars, with the Alfa Romeo being a slightly better choice apparently. 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, still it doesn't help us solve our dilemma, does it? Furthermore, 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.Reliability
Manufacturers have been building their reliability reputation for decades now and, generally speaking, it appears that Audi does have a slight advantage, when all the models are taken into account. That's the official data, while our visitors describe reliability of Alfa Romeo with an average rating of 4.2, and models under the Audi badge with 4.1 out of 5. The same official information place 159 as average reliability-wise, and A4 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 4.3 out of 5.Performance & Fuel economy
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 212 kilometers per hour, 10km/h more than the other car. When it comes to fuel economy the winner has to be the Italian car, averaging around 5.1 liters of fuel per 100 kilometers (55 mpg), in combined cycle. We can't ignore that 12% difference compared to the German 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 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... 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.
