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 86hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 70hp engine designed by FIAT.

The first thing to look into here would be the results from European New Car Assessment Programme (Euro NCAP) tests performed on the two cars. Good thing is that both vehicles got tested, 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, still it doesn't help us solve our dilemma, does it? On the other hand, taking kerb weight as an important factor into account, the German car offers a marginal difference of 5% more metal.

Reliability is not the best thing to consider on the make level, but it is worth mentioning 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. Independent research findings rank Grand Modus as average reliability-wise, and Meriva 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.

Renault is way more agile, reaching 100km/h in 4.8 seconds less than its competitor. In addition to that it accelerates all the way to 171 kilometers per hour, 14km/h more than the other car. When it comes to fuel economy the winner has to be the French car, averaging around 4.1 liters of fuel per 100 kilometers (69 mpg), in combined cycle. We can't ignore that 22% 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 offers slightly better overall protection and takes the lead. It all continues in the same direction, with Renault outracing its opponent in any situation possible, making it better choice for boy racers. 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. Anyway, that's the most objective conclusion I could've came up with and it's based solely on the information found on this website. Aspects such as design, practicality, brand value and driving experience are there for you to measure them out. 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.
