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 125hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 114hp 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. That aside, let's consider some other aspects which affect safety. Both vehicles belong to the small family car segment, which is generally classifying them somewhere in the middle safety-wise, but that fact doesn't break the tie between the two cars. On the other hand, taking kerb weight as an important factor into account, the Japanese car offers a considerable difference of 11% 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, 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. Independent research findings rank A3 as average reliability-wise, and Impreza 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 3.6, while the one under the competitor's bonnet gets 4.0 out of 5.

Audi is undoubtly more agile, reaching 100km/h in 2.8 seconds less than its competitor. In addition to that it accelerates all the way to 203 kilometers per hour, 14km/h more than the other car. When it comes to fuel economy the winner has to be the German car, averaging around 5.3 liters of fuel per 100 kilometers (53 mpg), in combined cycle. We can't ignore that 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 significantly better overall protection, taking the lead here. From there things take a different direction, with Audi being considerably quicker, thus putting more smile on driver's face. To make things even better, it consumps less fuel! I believe that, when we take all into account, we have only one winner here - the Audi. Anyway, that's the most objective conclusion I could've came up with and it's based solely on the information found on this website.
