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 diesel engine choice they offer. 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. 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 Swedish car offers a marginal difference of 2% more metal.

Manufacturers have been building their reliability reputation for decades now and, generally speaking, it appears that SAAB does have a slight advantage, at least on all of the models level. That's the official data, while our visitors describe reliability of Mercedes Benz with an average rating of 4.3, and models under the SAAB badge with 4.2 out of 5. Some independent research have also placed CLS as average reliability-wise, and 9-5 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 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 2.8 seconds less than its competitor. In addition to that it accelerates all the way to 250 kilometers per hour, 30km/h more than the other car. When it comes to fuel economy things look pretty much the same for both cars, averaging around 6.7 liters of fuel per 100 kilometers (42 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 outracing its opponent in any situation possible, making it better choice for boy racers. Fuel consumption is more or less the same. I believe that, when we take all into account, we have only one winner here - the SAAB. 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.
