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 (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 286hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 180hp engine designed by FIAT.

The first thing to look into here would be the results from European New Car Assessment Programme (Euro NCAP) tests performed on the two cars. Good thing is that both vehicles got tested, with the same number of safety stars gained in the process. 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, but that fact doesn't break the tie between the two cars. Furthermore, taking kerb weight as an important factor into account, the German car offers a considerable difference of 12% 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, at least on all of the models level. That's the official data, 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. Some independent research have also placed 3 Series as average reliability-wise, and 9-3 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 4.3, while the one under the competitor's bonnet gets 3.7 out of 5.

BMW is undoubtly more agile, reaching 100km/h in 2.5 seconds less than its competitor. In addition to that it accelerates all the way to 250 kilometers per hour, 25km/h more than the other car. When it comes to fuel economy the winner has to be the Swedish car, averaging around 5.3 liters of fuel per 100 kilometers (53 mpg), in combined cycle. We can't ignore that 26% 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 German car offers significantly better overall protection, taking the lead here. It all continues in the same 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 BMW. 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.
