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 5-door wagon body style within the same 'Large family 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 6-cylinder, 24-valves 204hp 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. Still, apart from the official crash test results there are other things we need to be aware of. 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, taking kerb weight as an important factor into account, the German car offers a marginal difference of 6% 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 official statistics, 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. The same official information place 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 4.3, while the one under the competitor's bonnet gets 3.8 out of 5.

BMW is way more agile, reaching 100km/h in 3.9 seconds less than its competitor. In addition to that it accelerates all the way to 237 kilometers per hour, 37km/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 19% difference compared to the German 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 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... No mistake, whatever you decide here, but I'd still go for 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.
