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 4 x 4 in the case of the Subaru). The first one has a BMW-engineered powertrain under the hood, a 4-cylinder, 16-valves 116hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 150hp engine designed by Subaru.

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 same number of safety stars gained in the process. 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, but that fact doesn't break the tie between the two cars. On the other hand, when it comes to weight, a factor that most people underestimate, the Japanese car offers a marginal difference of 7% more metal.

Reliability is not the best thing to consider on the make level, but it is worth mentioning that Subaru does have a slight advantage, at least on all of the models level. 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 Subaru badge with 4.2 out of 5. The same official information place 3 Series as average reliability-wise, and Legacy 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 4.5, while the one under the competitor's bonnet gets 4.7 out of 5.

Subaru is undoubtly more agile, reaching 100km/h in 1.6 seconds less than its competitor. In addition to that it accelerates all the way to 203 kilometers per hour, 3km/h more than the other car. When it comes to fuel economy the winner has to be the German car, averaging around 4.5 liters of fuel per 100 kilometers (63 mpg), in combined cycle. We can't ignore that 27% difference compared to the Japanese car.

Subaru 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 Japanese car offers slightly better overall protection and takes the lead. It all continues in the same direction, with Subaru 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. 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. 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.
