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 Volvo-engineered powertrain under the hood, a 6-cylinder, 24-valves 304hp unit, while the other one gets its power and torque from a 6-cylinder, 24-valves 306hp engine designed by BMW.

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. 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? On the other hand, if we'd like to consider vehicle mass in this context too, which we definitely should, the German car offers a marginal difference of 7% more metal.

I don't like generalizing things when it comes to reliability, although it does seem that Volvo does have a slight advantage, all the models observed together. These are the official statistics, while our visitors describe reliability of Volvo with an average rating of 4.6, and models under the BMW badge with 4.2 out of 5. Independent research findings rank S80 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 the Swedish car rank it on average as 4.6, while the one under the competitor's bonnet gets 4.0 out of 5.

BMW is undoubtly more agile, reaching 100km/h in 1.1 seconds less than its competitor. In addition to that it accelerates all the way to 250 kilometers per hour, exactly the same as the other car does. When it comes to fuel economy an obvious choice would be the German car, averaging around 7.6 liters of fuel per 100 kilometers (37 mpg), in combined cycle. That's 30% difference compared to the Swedish 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. To make things even better, it consumps less fuel! All together, there's not much more to say, in this case I wouldn't even consider anything but BMW. In any case that's my personal view, built upon all the data available to me. What should decide here though is the way you feel about the two vehicles, and I hope you'll find my guidelines useful in the process. 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.
