Virtual Adviser's™ opinion
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 luxury car segment and utilize the same 5-door wagon body style and the rear 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 6-cylinder, 24-valves 231hp unit, while the other one gets its power and torque from a 6-cylinder, 24-valves 258hp 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. Moving further on, let's take a closer look at some additional safety-related facts. Both vehicles belong to the luxury car segment, which is generally a very good thing safety-wise, still it doesn't help us solve our dilemma, does it? Furthermore, taking kerb weight as an important factor into account, Mercedes Benz E offers a marginal difference of 5% more metal.Reliability
Manufacturers have been building their reliability reputation for decades now and, generally speaking, it appears that both brands display similar results in faults and breakdowns, when all the models are taken into account. These are the results of an independent reasearch, while our visitors describe reliability of Mercedes Benz with an average rating of 4.4, and models under the BMW badge with 4.2 out of 5. Independent research findings rank E as average reliability-wise, and 5 Series is more or less at the same level.Above it all, drivers of cars with the same engine as Mercedes Benz E rank it on average as 4.2, while the one under the competitor's bonnet gets 4.7 out of 5.Performance & Fuel economy
BMW is undoubtly more agile, reaching 100km/h in 1.6 seconds less than its competitor. In addition to that it accelerates all the way to 247 kilometers per hour, 15km/h more than the other car. When it comes to fuel economy the winner has to be Mercedes Benz E, averaging around 4.4 liters of fuel per 100 kilometers (64 mpg), in combined cycle. We can't ignore that 34% difference compared to 5 Series.
BMW 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 E offers slightly better overall protection and takes the lead. From there things take a different direction, with BMW being considerably quicker, thus putting more smile on driver's face. It does come at a cost though, and that's the fuel consumption... I believe that, when we take all into account, we have only one winner here - 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.
