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. 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, still it doesn't help us solve our dilemma, does it? On the other hand, when it comes to weight, a factor that most people underestimate, the German car offers a considerable difference of 28% more metal.

Reliability is not the best thing to consider on the make level, but it is worth mentioning 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 4.1, and models under the Mercedes Benz badge with 4.4 out of 5. Unfortunatelly, I don't have enough insight that would allow me to comment in more details on the specific models level. We should definitely mention that owners of cars with the same powertrain as the French car rank it on average as 4.5, 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 offering somewhat better performance, just enough to call it quicker. 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. In case you have two minutes to spare I invite you to define your needs, desires and budget and see which car would be chosen by the virtual adviser™, among thousands of similar, yet so different vehicles.
