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 (rear for the BMW and front in the case of the Volvo). The first one has a BMW-engineered powertrain under the hood, a 6-cylinder, 24-valves 204hp unit, while the other one gets its power and torque from a 5-cylinder, 20-valves 215hp engine designed by Volvo.

The fact that the BMW 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 luxury car segment, which is generally a very good thing safety-wise, but that fact doesn't break the tie between the two cars. Furthermore, taking kerb weight as an important factor into account, the German car offers a marginal difference of 9% more metal.

Reliability is not the best thing to consider on the make level, but it is worth mentioning that Volvo does have a slight advantage, 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 Volvo badge with 3.2 out of 5. Independent research findings rank 5 Series as average reliability-wise, and S80 is more or less at the same level.That apart, owners of different cars powered by the same engine as the German car rank it on average as 1.7, while the one under the competitor's bonnet gets 3.2 out of 5.

BMW is a bit more agile, reaching 100km/h in 0.4 seconds less than its competitor. In addition to that it accelerates all the way to 236 kilometers per hour, 6km/h more than the other car. When it comes to fuel economy the winner has to be the Swedish car, averaging around 4.6 liters of fuel per 100 kilometers (61 mpg), in combined cycle. We can't ignore that 35% 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 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... It's not difficult to say then that if I'd need to make a choice, it would definitely be 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.
