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 Alfa Romeo-engineered powertrain under the hood, a 4-cylinder, 16-valves 240hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 156hp engine designed by Mercedes Benz.

Both vehicles got tested by European New Car Assessment Programme (Euro NCAP), with the Mercedes Benz displaying significantly better structural stability. Still, apart from the official crash test results there are other things we need to be aware of. 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, when it comes to weight, a factor that most people underestimate, the Italian car offers a marginal difference of 2% more metal.

Manufacturers have been building their reliability reputation for decades now and, generally speaking, it appears that Mercedes Benz 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 Mercedes Benz badge with 4.4 out of 5. The same official information place Giulietta as average reliability-wise, and A is more or less at the same level.Above it all, drivers of cars with the same engine as the Italian car rank it on average as 3.0, while the one under the competitor's bonnet gets 5.0 out of 5.

Alfa Romeo is undoubtly more agile, reaching 100km/h in 2.1 seconds less than its competitor. In addition to that it accelerates all the way to 244 kilometers per hour, 20km/h more than the other car. When it comes to fuel economy the winner has to be the German car, averaging around 5.7 liters of fuel per 100 kilometers (50 mpg), in combined cycle. We can't ignore that 19% difference compared to the Italian car.

Mercedes Benz is apparently more reliable, not too much, but just enough. 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 Mercedes Benz. 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. 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.
