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 Renault-engineered powertrain under the hood, a 4-cylinder, 8-valves 67hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 70hp engine designed by FIAT.

Both vehicles got tested by European New Car Assessment Programme (Euro NCAP), with the Renault 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. On the other hand, when it comes to weight, a factor that most people underestimate, the German car offers a marginal difference of 7% more metal.

Manufacturers have been building their reliability reputation for decades now and, generally speaking, it appears that Renault does have a slight advantage, at least on all of the models level. That's the official data, while our visitors describe reliability of Renault with an average rating of 4.1, and models under the Opel badge with 4.2 out of 5. Unfortunatelly, I don't have enough insight that would allow me to comment in more details on the specific models level. That apart, owners of different cars powered by the same engine as the French car rank it on average as 4.3 out of 5, exactly the same as the other one.

Renault 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 158 kilometers per hour, 1km/h more than the other car. When it comes to fuel economy things look pretty much the same for both cars, averaging around 4.9 liters of fuel per 100 kilometers (58 mpg), in combined cycle.

Renault 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 French car offers slightly better overall protection and takes the lead. It all continues in the same direction, with Renault 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 Renault. 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. 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.
