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 small family car segment and utilize the same 5-door hatchback body style and the front wheel drive system, it all comes up to the specific petrol engine choice they offer. The first one has a BMW-engineered powertrain under the hood, a 3-cylinder, 12-valves 109hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 150hp engine designed by Volkswagen.

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. 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? Furthermore, when it comes to weight, a factor that most people underestimate, 1 Series offers a marginal difference of 3% more metal.

I don't like generalizing things when it comes to reliability, although it does seem that both brands display similar results in faults and breakdowns, at least on all of the models level. These are the official statistics, while our visitors describe reliability of BMW with an average rating of 4.1, and models under the Audi badge with 4.2 out of 5. Unfortunatelly, I don't have enough insight that would allow me to comment in more details on the specific models level. That apart, owners of different cars powered by the same engine as 1 Series rank it on average as 3.0, while the one under the competitor's bonnet gets 4.8 out of 5.

Audi is undoubtly more agile, reaching 100km/h in 2.2 seconds less than its competitor. In addition to that it accelerates all the way to 224 kilometers per hour, 24km/h more than the other car. When it comes to fuel economy the winner has to be Audi A3, averaging around 4.8 liters of fuel per 100 kilometers (59 mpg), in combined cycle. We can't ignore that 21% difference compared to 1 Series.

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, 1 Series 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. 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.
