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 mpv segment and utilize the same 5-door MPV 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, 8-valves 63hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 75hp engine designed by Mercedes Benz.

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 Mercedes Benz being a slightly better choice apparently. That aside, let's consider some other aspects which affect safety. Both vehicles belong to the mpv segment, which is generally a good thing 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 1% more metal.

Manufacturers have been building their reliability reputation for decades now and, generally speaking, it appears that FIAT as a brand displays somewhat better results, all the models observed together. That's the official data, while our visitors describe reliability of FIAT with an average rating of 4.3, and models under the Mercedes Benz badge with 4.4 out of 5. Some independent research have also placed Doblo as average reliability-wise, and Vaneo is more or less at the same level.We should definitely mention that owners of cars with the same powertrain as the Italian car rank it on average as 4.5 out of 5, exactly the same as the other one.

Mercedes Benz is undoubtly more agile, reaching 100km/h in 1.4 seconds less than its competitor. In addition to that it accelerates all the way to 149 kilometers per hour, 8km/h more than the other car. When it comes to fuel economy an obvious choice would be the German car, averaging around 5.7 liters of fuel per 100 kilometers (50 mpg), in combined cycle. That's 35% difference compared to the Italian car!

FIAT 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. It all continues in the same direction, with Mercedes Benz being considerably quicker, thus putting more smile on driver's face. To make things even better, it consumps less fuel! All together, there's not much more to say, in this case I wouldn't even consider anything but Mercedes Benz. 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. I suggest you spend two more minutes in order to find out which car, based on your needs and budget, would be picked by the virtual adviser™, among thousands of similar, yet so different vehicles.
