Two significantly similar cars, no doubt about that. Still, each one has something different to offer. Having both cars powered by petrol 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 (4 x 4 for the SAAB and rear in the case of the Mercedes Benz). The first one has a Opel-engineered powertrain under the hood, a 6-cylinder, 24-valves 300hp unit, while the other one gets its power and torque from a 6-cylinder, 24-valves 306hp engine designed by Mercedes Benz.

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. 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 it doesn't do much to help us decide between the two. Furthermore, when it comes to weight, a factor that most people underestimate, the Swedish car offers a considerable difference of 13% 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 official statistics, while our visitors describe reliability of SAAB with an average rating of 4.2, and models under the Mercedes Benz badge with 4.4 out of 5. The same official information place 9-5 as average reliability-wise, and CLS is more or less at the same level.We should definitely mention that owners of cars with the same powertrain as the Swedish car rank it on average as 5.0 out of 5, exactly the same as the other one.

Mercedes Benz is a bit more agile, reaching 100km/h in 0.8 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 6.8 liters of fuel per 100 kilometers (42 mpg), in combined cycle. That's 56% difference compared to the Swedish car!

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 offering somewhat better performance, just enough to call it quicker. To make things even better, it consumps less fuel! No mistake, whatever you decide here, but I'd still go for the SAAB. Nevertheless, let's not forget that people have different preferences and needs, so what really counts is your personal feel.
