Two significantly similar cars, no doubt about that. Still, each one has something different to offer. Having both cars powered by diesel engines and utilizing the 5-door MPV body style within the same 'MPV' segment, the only major difference here really is their wheel drive configuration (front for the Renault and rear in the case of the Mercedes Benz). The first one has a Renault-engineered powertrain under the hood, a 4-cylinder, 16-valves 160hp unit, while the other one gets its power and torque from a 6-cylinder, 24-valves 190hp engine designed by Mercedes Benz.

The fact that the Renault got tested by the European New Car Assessment Programme (Euro NCAP), while the other contender didn't, puts it sky-high safety-wise, in my eyes at least. 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 that fact doesn't break the tie between the two cars. On the other hand, taking kerb weight as an important factor into account, the German car offers a considerable difference of 28% more metal.

I don't like generalizing things when it comes to reliability, although it does seem that Renault as a brand displays somewhat better results, at least on all of the models level. These are the official statistics, while our visitors describe reliability of Renault with an average rating of 4.2, and models under the Mercedes Benz badge with 4.3 out of 5. Unfortunatelly, I don't have enough insight that would allow me to comment in more details on the specific models level. Above it all, drivers of cars with the same engine as the French car rank it on average as 4.3, while the one under the competitor's bonnet gets 4.4 out of 5.

Mercedes Benz is a bit more agile, reaching 100km/h in 0.2 seconds less than its competitor. In addition to that it accelerates all the way to 215 kilometers per hour, 13km/h more than the other car. When it comes to fuel economy an obvious choice would be the French car, averaging around 4.7 liters of fuel per 100 kilometers (60 mpg), in combined cycle. That's 62% 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 Mercedes Benz 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. 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.
