Virtual Adviser's™ opinion

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 luxury car segment and utilize the same 4-door sedan body style and the rear wheel drive system, it all comes up to the specific petrol engine choice they offer. The first one has a BMW-engineered powertrain under the hood, a 6-cylinder, 24-valves 190hp unit, while the other one gets its power and torque from a 6-cylinder, 24-valves 204hp engine designed by Mercedes Benz.

Safety

Both vehicles got tested by European New Car Assessment Programme (Euro NCAP), with the Mercedes Benz being a slightly better choice apparently. That aside, let's consider some other aspects which affect safety. 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? On the other hand, when it comes to weight, a factor that most people underestimate, Mercedes Benz E offers a marginal difference of 5% 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 BMW with an average rating of 4.3, and models under the Mercedes Benz badge with 4.5 out of 5. Some independent research have also placed 5 Series 23% below average, and E 42% above the first one. That apart, owners of different cars powered by the same engine as 5 Series rank it on average as 3.0 out of 5, exactly the same as the other one.

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 237 kilometers per hour, 3km/h less than the other car. When it comes to fuel economy an obvious choice would be 5 Series, averaging around 7.3 liters of fuel per 100 kilometers (39 mpg), in combined cycle. That's 33% difference compared to Mercedes Benz E!

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 E offers much better overall protection, which launches it ahead of the other contender. From there things take a different direction, with BMW offering somewhat better performance, just enough to call it quicker. 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 BMW. 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. I suggest you spend two more minutes in order to find out which car, based on your needs and budget, would be picked by the virtual adviser™, among more than 12.000 different ones in our database.
