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 'Large family car' segment, the only major difference here really is their wheel drive configuration (4 x 4 for the BMW and front in the case of the SAAB). The first one has a BMW-engineered powertrain under the hood, a 6-cylinder, 24-valves 184hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 125hp engine designed by Opel.

Both vehicles got tested by European New Car Assessment Programme (Euro NCAP), with the SAAB being a slightly better choice apparently. That aside, let's consider some other aspects which affect safety. Both vehicles belong to the large family car segment, which is generally a good thing safety-wise, still it doesn't help us solve our dilemma, does it? Furthermore, when it comes to weight, a factor that most people underestimate, the German car offers a marginal difference of 9% more metal.

Manufacturers have been building their reliability reputation for decades now and, generally speaking, it appears 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 BMW with an average rating of 4.1, and models under the SAAB badge with 4.2 out of 5. Independent research findings rank 3 Series as average reliability-wise, and 9-3 is more or less at the same level.Above it all, drivers of cars with the same engine as the German car rank it on average as 5.0, while the one under the competitor's bonnet gets 3.9 out of 5.

BMW is way more agile, reaching 100km/h in 3 seconds less than its competitor. In addition to that it accelerates all the way to 224 kilometers per hour, 24km/h more than the other car. When it comes to fuel economy the winner has to be the Swedish car, averaging around 5.7 liters of fuel per 100 kilometers (50 mpg), in combined cycle. We can't ignore that 33% difference compared to the German car.

BMW 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 slightly better overall protection and takes the lead. From there things take a different direction, with BMW outracing its opponent in any situation possible, making it better choice for boy racers. It does come at a cost though, and that's the fuel consumption... At the end, as much as I'd like to give you a winner here, it's simply a pure tie if you ask me. 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.
