Two significantly similar cars, no doubt about that. Still, each one has something different to offer. Having both cars powered by petrol engines and utilizing the 4-door sedan body style within the same 'Small family car' segment, the only major difference here really is their wheel drive configuration (front for the Audi and 4 x 4 in the case of the Subaru). The first one has a Volkswagen-engineered powertrain under the hood, a 4-cylinder, 16-valves 180hp 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 small family car segment, which is generally classifying them somewhere in the middle safety-wise, still it doesn't help us solve our dilemma, does it? On the other hand, when it comes to weight, a factor that most people underestimate, the Japanese car offers a marginal difference of 8% more metal.

Manufacturers have been building their reliability reputation for decades now and, generally speaking, it appears that Subaru does have a slight advantage, when all the models are taken into account. That's the official data, while our visitors describe reliability of Audi, as well as Subaru, with the same average rating of 4.2 out of 5. Independent research findings rank A3 as average reliability-wise, and Impreza 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 4.8 out of 5, exactly the same as the other one.

Audi is way more agile, reaching 100km/h in 3.3 seconds less than its competitor. In addition to that it accelerates all the way to 232 kilometers per hour, 35km/h more than the other car. When it comes to fuel economy an obvious choice would be the German car, averaging around 5.8 liters of fuel per 100 kilometers (49 mpg), in combined cycle. That's 36% 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. From there things take a different direction, with Audi outracing its opponent in any situation possible, making it better choice for boy racers. To make things even better, it consumps less fuel! All together, there's not much more to say, in this case I wouldn't even consider anything but 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. 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.
