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 4-door sedan body style and the 4 x 4 wheel drive system, it all comes up to the specific petrol engine choice they offer. The first one has a Mercedes Benz-engineered powertrain under the hood, a 8-cylinder, 32-valves 612hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 300hp engine designed by Volvo.
SafetyA 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. 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, but it doesn't do much to help us decide between the two. On the other hand, if we'd like to consider vehicle mass in this context too, which we definitely should, the Swedish car offers a marginal difference of 9% more metal.
ReliabilityManufacturers have been building their reliability reputation for decades now and, generally speaking, it appears that Volvo does have a slight advantage, when all the models are taken into account. That's the official data, while our visitors describe reliability of Mercedes Benz with an average rating of 4.4, and models under the Volvo badge with 4.6 out of 5. Unfortunatelly, I don't have enough insight that would allow me to comment in more details on the specific models level. That apart, owners of different cars powered by the same engine as the German car rank it on average as 3.0 out of 5, exactly the same as the other one.
Performance & Fuel economyMercedes Benz is undoubtly more agile, reaching 100km/h in 2.8 seconds less than its competitor. In addition to that it accelerates all the way to 300 kilometers per hour, 120km/h more than the other car. When it comes to fuel economy an obvious choice would be the Swedish car, averaging around 6.7 liters of fuel per 100 kilometers (42 mpg), in combined cycle. That's 73% difference compared to the German car!
Verdict
Volvo 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, the Swedish car offers slightly better overall protection and takes the lead. From there things take a different direction, with Mercedes Benz being considerably quicker, thus putting more smile on driver's face. It does come at a cost though, and that's the fuel consumption... All together, there's not much more to say, in this case I wouldn't even consider anything but Volvo. 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. In case you have two minutes to spare I invite you to define your needs, desires and budget and see which car would be chosen by the virtual adviser™, out of 12.000+ vehicles we currently have in our database.
