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 Mercedes Benz and front in the case of the SAAB). The first one has a Mercedes Benz-engineered powertrain under the hood, a 6-cylinder, 24-valves 265hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 195hp engine designed by FIAT.

The fact that the SAAB 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. 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 1% more metal.

Reliability is not the best thing to consider on the make level, but it is worth mentioning that SAAB does have a slight advantage, all the models observed together. These are the results of an independent reasearch, while our visitors describe reliability of Mercedes Benz with an average rating of 4.4, and models under the SAAB badge with 4.1 out of 5. The same official information place CLS as average reliability-wise, and 9-5 is more or less at the same level.We should definitely mention that owners of cars with the same powertrain as the German car rank it on average as 4.8, while the one under the competitor's bonnet gets 5.0 out of 5.

Mercedes Benz is undoubtly more agile, reaching 100km/h in 2.9 seconds less than its competitor. In addition to that it accelerates all the way to 250 kilometers per hour, 20km/h more than the other car. When it comes to fuel economy things look pretty much the same for both cars, averaging around 6.1 liters of fuel per 100 kilometers (47 mpg), in combined cycle.

SAAB 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 beats the other contender by far, making it the best choice without even considering other things. From there things take a different direction, with Mercedes Benz being considerably quicker, thus putting more smile on driver's face. 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 SAAB. 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. 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.
