Two significantly similar cars, no doubt about that. Still, each one has something different to offer. Having both cars powered by petrol 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 Mitsubishi and rear in the case of the Mercedes Benz). The first one has a Mitsubishi-engineered powertrain under the hood, a 4-cylinder, 16-valves 164hp unit, while the other one gets its power and torque from a 6-cylinder, 24-valves 231hp engine designed by Mercedes Benz.

Unfortunatelly, neither of the two vehicles was submitted to the European New Car Assessment Programme (Euro NCAP) testing. This makes it virtually impossible for me to pick one over the other and I'm generally against buying such cars as the safety should really always come first. 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. On the other hand, if we'd like to consider vehicle mass in this context too, which we definitely should, the German car offers a considerable difference of 25% more metal.

Manufacturers have been building their reliability reputation for decades now and, generally speaking, it appears that Mitsubishi does have a slight advantage, all the models observed together. These are the results of an independent reasearch, while our visitors describe reliability of Mitsubishi with an average rating of 4.6, and models under the Mercedes Benz badge with 4.4 out of 5. The same official information place Grandis as average reliability-wise, and R is more or less at the same level.That apart, owners of different cars powered by the same engine as the Japanese car rank it on average as 5.0, while the one under the competitor's bonnet gets 4.0 out of 5.

Mercedes Benz is a bit more agile, reaching 100km/h in 0.4 seconds less than its competitor. In addition to that it accelerates all the way to 222 kilometers per hour, 22km/h more than the other car. When it comes to fuel economy the winner has to be the Japanese car, averaging around 9.4 liters of fuel per 100 kilometers (30 mpg), in combined cycle. We can't ignore that 16% difference compared to the German car.

Mitsubishi 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 German car offers significantly better overall protection, taking the lead here. It all continues in the same 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... It's really tough to make a final decision here, but if I'd need to, I'd say Mitsubishi. 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.
