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 5-door hatchback body style and the front 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 170hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 156hp engine designed by Mercedes Benz.

The first thing to look into here would be the results from European New Car Assessment Programme (Euro NCAP) tests performed on the two cars. Good thing is that both vehicles got tested, with the Mercedes Benz displaying significantly better structural stability. Moving further on, let's take a closer look at some additional safety-related facts. Both vehicles belong to the small family car segment, which is generally classifying them somewhere in the middle safety-wise, but it doesn't do much to help us decide between the two. 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 1% more metal.

I don't like generalizing things when it comes to reliability, although it does seem that Mercedes Benz 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 Mercedes Benz badge with 4.4 out of 5. Independent research findings rank Giulietta as average reliability-wise, and A 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 4.8, while the one under the competitor's bonnet gets 5.0 out of 5.

Alfa Romeo is a bit more agile, reaching 100km/h in 0.4 seconds less than its competitor. Still, it lacks the power to win the top speed competition, topping at 218 kilometers per hour, 6km/h less than the other car. When it comes to fuel economy the winner has to be the Italian car, averaging around 4.9 liters of fuel per 100 kilometers (58 mpg), in combined cycle. We can't ignore that 16% difference compared to the German car.

Mercedes Benz 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 offering somewhat better performance, just enough to call it quicker. To make things even better, it consumps less fuel! No mistake, whatever you decide here, but I'd still go for the Alfa Romeo. 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. Aspects such as design, practicality, brand value and driving experience are there for you to measure them out.
