Well, these are two pretty similar cars we have here! It's only details that could potentially make the difference. Considering they both belong to the large family car segment and utilize the same 5-door wagon body style and the 4 x 4 wheel drive system, it all comes up to the specific diesel engine choice they offer. The first one has a Audi-engineered powertrain under the hood, a 6-cylinder, 24-valves 240hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 150hp engine designed by Subaru.

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 13% more metal.

I don't like generalizing things when it comes to reliability, although it does seem that Subaru does have a slight advantage, all the models observed together. These are the official statistics, while our visitors describe reliability of Audi, as well as Subaru, with the same average rating of 4.2 out of 5. Some independent research have also placed A4 as average reliability-wise, and Legacy 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 4.7 out of 5.

Audi is way more agile, reaching 100km/h in 3 seconds less than its competitor. In addition to that it accelerates all the way to 237 kilometers per hour, 34km/h more than the other car. When it comes to fuel economy the winner has to be the Japanese car, averaging around 6.1 liters of fuel per 100 kilometers (46 mpg), in combined cycle. We can't ignore that 18% difference compared to the German 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 German car offers significantly better overall protection, taking the lead here. It all continues in the same direction, with Audi 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... It's really tough to make a final decision here, but if I'd need to, I'd say Audi. 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. Also, you could use the oportunity to find out which car, everything taken into account, would be the perfect choice for you in the eyes of the virtual adviser™, among thousands of similar, yet so different vehicles.
