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 SAAB). The first one has a BMW-engineered powertrain under the hood, a 4-cylinder, 16-valves 177hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 150hp engine designed by FIAT.

A starting point here would be to take a look at the results from European New Car Assessment Programme (Euro NCAP) tests which were performed on both of the cars, with the SAAB being a slightly better choice apparently. 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, 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 1% more metal.

I don't like generalizing things when it comes to reliability, although it does seem that SAAB does have a slight advantage, when all the models are taken into account. These are the results of an independent reasearch, while our visitors describe reliability of BMW with an average rating of 4.2, and models under the SAAB badge with 4.1 out of 5. Some independent research have also placed 5 Series 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 3.7, while the one under the competitor's bonnet gets 4.1 out of 5.

BMW is undoubtly more agile, reaching 100km/h in 2.4 seconds less than its competitor. In addition to that it accelerates all the way to 231 kilometers per hour, 26km/h more than the other car. When it comes to fuel economy the winner has to be the German car, averaging around 5.1 liters of fuel per 100 kilometers (55 mpg), in combined cycle. We can't ignore that 25% 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 offers much better overall protection, which launches it ahead of the other contender. From there things take a different direction, with BMW being considerably quicker, thus putting more smile on driver's face. To make things even better, it consumps less fuel! No mistake, whatever you decide here, but I'd still go for the BMW. Anyway, that's the most objective conclusion I could've came up with and it's based solely on the information found on this website. Aspects such as design, practicality, brand value and driving experience are there for you to measure them out. 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.
