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 Opel-engineered powertrain under the hood, a 4-cylinder, 16-valves 125hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 128hp engine designed by Peugeot.

The fact that the Opel got tested by the European New Car Assessment Programme (Euro NCAP), while the other contender didn't, isn't really an advantage, taken the poor 3-star rating it received. 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, still it doesn't help us solve our dilemma, does it? On the other hand, if we'd like to consider vehicle mass in this context too, which we definitely should, the Italian car offers a considerable difference of 15% more metal.

I don't like generalizing things when it comes to reliability, although it does seem that FIAT does have a slight advantage, when all the models are taken into account. These are the results of an independent reasearch, while our visitors describe reliability of Opel with an average rating of 4.2, and models under the FIAT badge with 4.3 out of 5. The same official information place Zafira as average reliability-wise, and Ulysse 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 3.8, while the one under the competitor's bonnet gets 3.0 out of 5.

Opel is undoubtly more agile, reaching 100km/h in 1.1 seconds less than its competitor. In addition to that it accelerates all the way to 187 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 6.5 liters of fuel per 100 kilometers (43 mpg), in combined cycle. We can't ignore that 14% 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 this case though, it seems that both cars show similar levels of passenger protection all together, so that won't break a tie. But one thing that actually could is the performance, with Opel 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 Opel. 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.
