Virtual Adviser's™ opinion
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 3-door hatchback body style within the same 'Small 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 Audi). The first one has a BMW-engineered powertrain under the hood, a 4-cylinder, 16-valves 190hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 184hp engine designed by Volkswagen.
SafetyThe 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. Moving further on, let's take a closer look at some additional safety-related facts. 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, Audi A3 offers a marginal difference of 9% more metal.
ReliabilityI don't like generalizing things when it comes to reliability, although it does seem that both brands display similar results in faults and breakdowns, all the models observed together. These are the results of an independent reasearch, while our visitors describe reliability of BMW, as well as Audi, with the same average rating of 4.2 out of 5. Some independent research have also placed 1 Series as average reliability-wise, and A3 is more or less at the same level.That apart, owners of different cars powered by the same engine as 1 Series rank it on average as 3.6, while the one under the competitor's bonnet gets 4.9 out of 5.
Performance & Fuel economyAudi is a bit more agile, reaching 100km/h in 0.3 seconds less than its competitor. In addition to that it accelerates all the way to 230 kilometers per hour, 2km/h more than the other car. When it comes to fuel economy the winner has to be 1 Series, averaging around 4.1 liters of fuel per 100 kilometers (69 mpg), in combined cycle. We can't ignore that 22% difference compared to Audi A3.
Verdict
Audi 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, Audi A3 offers slightly better overall protection and takes the lead. It all continues in the same direction, with Audi offering somewhat better performance, just enough to call it quicker. 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 BMW. Nevertheless, let's not forget that people have different preferences and needs, so what really counts is your personal feel. I'm only here to help. I suggest you spend two more minutes in order to find out which car, based on your needs and budget, would be picked by the virtual adviser™, among thousands of similar, yet so different vehicles.
