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 petrol engine choice they offer. The first one has a Renault-engineered powertrain under the hood, a 4-cylinder, 16-valves 163hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 200hp engine designed by Opel.

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 Renault 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 mpv segment, which is generally a good thing safety-wise, but it doesn't do much to help us decide between the two. Furthermore, taking kerb weight as an important factor into account, the French car offers a marginal difference of 5% more metal.

I don't like generalizing things when it comes to reliability, although it does seem that Renault does have a slight advantage, when all the models are taken into account. That's the official data, while our visitors describe reliability of Renault, as well as Opel, with the same average rating of 4.2 out of 5. The same official information place Grand Scenic as average reliability-wise, and Zafira is more or less at the same 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.

Opel 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 220 kilometers per hour, 14km/h more than the other car. When it comes to fuel economy an obvious choice would be the French car, averaging around 8.1 liters of fuel per 100 kilometers (35 mpg), in combined cycle. That's 25% difference compared to the German car!

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 beats the other contender by far, making it the best choice without even considering other things. From there things take a different direction, with Opel outracing its opponent in any situation possible, making it better choice for boy racers. 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 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.
