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 Honda-engineered powertrain under the hood, a 4-cylinder, 16-valves 142hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 140hp engine designed by Mercedes Benz.

Both vehicles got tested by European New Car Assessment Programme (Euro NCAP), with the Mercedes Benz being a slightly better choice apparently. Moving further on, let's take a closer look at some additional safety-related facts. 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 Japanese car offers a considerable difference of 20% more metal.

I don't like generalizing things when it comes to reliability, although it does seem that Honda is significantly less fault-prone, at least on all of the models level. That's the official data, while our visitors describe reliability of Honda with an average rating of 4.7, and models under the Mercedes Benz badge with 4.4 out of 5. The same official information place FR-V as average reliability-wise, and B is more or less at the same level.We should definitely mention that owners of cars with the same powertrain as the Japanese car rank it on average as 4.8, 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 0.6 seconds less than its competitor. In addition to that it accelerates all the way to 200 kilometers per hour, 8km/h more than the other car. When it comes to fuel economy the winner has to be the German car, averaging around 5.6 liters of fuel per 100 kilometers (50 mpg), in combined cycle. We can't ignore that 13% difference compared to the Japanese car.

Honda is apparently more reliable, not too much, but just enough. The most important thing when deciding between any two vehicles should always be safety, both passive and active. In this case though, it seems that both cars show similar levels of passenger protection all together, so that won't break a tie. But one thing that actually could is the performance, with Mercedes Benz offering somewhat better performance, just enough to call it quicker. To make things even better, it consumps less fuel! It's not difficult to say then that if I'd need to make a choice, it would definitely be the Mercedes Benz. 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. Also, you could use the oportunity to find out which car, everything taken into account, would be the perfect choice for you in the eyes of the virtual adviser™, among thousands of similar, yet so different vehicles.
