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 suv body style within the same 'SUV' segment, the only major difference here really is their wheel drive configuration (rear for the BMW and 4 x 4 in the case of the Mercedes Benz). The first one has a BMW-engineered powertrain under the hood, a 4-cylinder, 16-valves 218hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 204hp engine designed by Mercedes Benz.

The fact that the Mercedes Benz 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 suv segment, which is generally a very 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, Mercedes Benz ML offers a marginal difference of 8% more metal.

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 BMW with an average rating of 4.1, and models under the Mercedes Benz badge with 4.3 out of 5. The same official information place X5 as average reliability-wise, and ML is more or less at the same level.Above it all, drivers of cars with the same engine as BMW X5 rank it on average as 3.3, while the one under the competitor's bonnet gets 4.8 out of 5.

BMW is a bit more agile, reaching 100km/h in 0.8 seconds less than its competitor. In addition to that it accelerates all the way to 220 kilometers per hour, 10km/h more than the other car. When it comes to fuel economy things look pretty much the same for both cars, averaging around 5.7 liters of fuel per 100 kilometers (50 mpg), in combined cycle.

Mercedes Benz 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 my opinion, everything taken into account, Mercedes Benz ML beats the other contender by far, making it the best choice without even considering other things. From there things take a different direction, with BMW outracing its opponent in any situation possible, making it better choice for boy racers. To make things even better, it consumps less fuel! 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. 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.
