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 diesel engine choice they offer. The first one has a Renault-engineered powertrain under the hood, a 4-cylinder, 8-valves 110hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 105hp engine designed by FIAT.

Both vehicles got tested by European New Car Assessment Programme (Euro NCAP), with the same number of safety stars gained in the process. 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, 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 German car offers a marginal difference of 1% more metal.

Reliability is not the best thing to consider on the make level, but it is worth mentioning that Mercedes Benz does have a slight advantage, at least on all of the models level. That's the official data, while our visitors describe reliability of Mercedes Benz with an average rating of 4.4, and models under the Alfa Romeo badge with 4.2 out of 5. Independent research findings rank A as average reliability-wise, and Giulietta is more or less at the same level.That apart, owners of different cars powered by the same engine as the German car rank it on average as 4.2, while the one under the competitor's bonnet gets 2.8 out of 5.

Both of the cars accelerate exactly the same, so we couldn't put one above the other. Car No. 1 reaches top speed of 185 kilometers per hour, 5km/h more than the other car. When it comes to fuel economy the winner has to be the German car, averaging around 3.8 liters of fuel per 100 kilometers (74 mpg), in combined cycle. We can't ignore that 16% difference compared to the Italian 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 slightly better overall protection and takes the lead. When it comes to performance, both vehicles provide similar experience, so I wouldn't point any of them out. the German car , on the other hand, consumps significantly less fuel, and that's a big plus. All together, there's not much more to say, in this case I wouldn't even consider anything but Mercedes Benz. 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™, among thousands of similar, yet so different vehicles.
