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 4-door sedan body style within the same 'Luxury car' segment, the only major difference here really is their wheel drive configuration (front for the Volvo and rear in the case of the Mercedes Benz). The first one has a Volvo-engineered powertrain under the hood, a 5-cylinder, 20-valves 163hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 170hp 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. 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, but it doesn't do much to help us decide between the two. On the other hand, taking kerb weight as an important factor into account, the German car offers a marginal difference of 8% more metal.

I don't like generalizing things when it comes to reliability, although it does seem that Volvo does have a slight advantage, at least on all of the models level. That's the official data, while our visitors describe reliability of Volvo with an average rating of 4.6, and models under the Mercedes Benz badge with 4.4 out of 5. Some independent research have also placed S80 as average reliability-wise, and E is more or less at the same level.That apart, owners of different cars powered by the same engine as the Swedish car rank it on average as 4.9, while the one under the competitor's bonnet gets 4.5 out of 5.

Mercedes Benz is undoubtly more agile, reaching 100km/h in 1 seconds less than its competitor. In addition to that it accelerates all the way to 228 kilometers per hour, 13km/h more than the other car. When it comes to fuel economy the winner has to be the Swedish car, averaging around 4.3 liters of fuel per 100 kilometers (66 mpg), in combined cycle. We can't ignore that 16% difference compared to the German car.

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 German car beats the other contender by far, making it the best choice without even considering other things. It all continues in the same 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... It's not difficult to say then that if I'd need to make a choice, it would definitely be 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. 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™, among thousands of similar, yet so different vehicles.
