Overview

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 4 x 4 wheel drive system, it all comes up to the specific diesel engine choice they offer. The first one has a Mercedes Benz-engineered powertrain under the hood, a 4-cylinder, 16-valves 136hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 150hp engine designed by BMW.

Safety

A starting point here would be to take a look at the results from European New Car Assessment Programme (Euro NCAP) tests which were performed on both of the cars, with the same number of safety stars gained in the process. 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 that fact doesn't break the tie between the two cars. Furthermore, if we'd like to consider vehicle mass in this context too, which we definitely should, Mercedes Benz B offers a marginal difference of 3% more metal.

Reliability

I don't like generalizing things when it comes to reliability, although it does seem that both brands display similar results in faults and breakdowns, all the models observed together. These are the results of an independent reasearch, while our visitors describe reliability of Mercedes Benz with an average rating of 4.3, and models under the BMW badge with 4.1 out of 5. Some independent research have also placed B 19% below average, and 2 Series those same 19% above the first one. Above it all, drivers of cars with the same engine as Mercedes Benz B rank it on average as 4.3, while the one under the competitor's bonnet gets 4.8 out of 5.

Performance & Fuel economy

BMW is a bit more agile, reaching 100km/h in 0.9 seconds less than its competitor. Still, it lacks the power to win the top speed competition, topping at 205 kilometers per hour, 2km/h less than the other car. When it comes to fuel economy things look pretty much the same for both cars, averaging around 5.1 liters of fuel per 100 kilometers (55 mpg), in combined cycle.

Verdict

Mercedes Benz 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, Mercedes Benz B offers slightly better overall protection and takes the lead. When it comes to performance, both vehicles provide similar experience, so I wouldn't point any of them out. Mercedes Benz B still consumps less fuel, which needs to be taken into consideration. I believe that, when we take all into account, we have only one winner here - the Mercedes Benz. 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.
