Two significantly similar cars, no doubt about that. Still, each one has something different to offer. Having both cars powered by diesel engines and utilizing the 4-door sedan body style within the same 'Large family car' segment, the only major difference here really is their wheel drive configuration (rear for the Alfa Romeo and 4 x 4 in the case of the Audi). The first one has a FIAT-engineered powertrain under the hood, a 4-cylinder, 16-valves 180hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 190hp engine designed by Volkswagen.

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. On the other hand, if we'd like to consider vehicle mass in this context too, which we definitely should, the German car offers a considerable difference of 20% more metal.

Manufacturers have been building their reliability reputation for decades now and, generally speaking, it appears 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 Alfa Romeo, as well as Audi, with the same average rating of 4.2 out of 5. Independent research findings rank Giulia 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 3.0, while the one under the competitor's bonnet gets 3.6 out of 5.

Both of the cars accelerate exactly the same, so we couldn't put one above the other. Car No. 2 is faster though, reaching top speed of 235 kilometers per hour, 5km/h more than the other car. When it comes to fuel economy things look pretty much the same for both cars, averaging around 4.4 liters of fuel per 100 kilometers (64 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 German car offers significantly better overall protection, taking the lead here. When it comes to performance, both vehicles provide similar experience, so I wouldn't point any of them out. the Italian car still consumps less fuel, which needs to be taken into consideration. At the end, as much as I'd like to give you a winner here, it's simply a pure tie if you ask me. 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.
