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 petrol engines and utilizing the 5-door hatchback body style within the same 'Small family car' segment, the only major difference here really is their wheel drive configuration (4 x 4 for the Audi and front in the case of the Opel). The first one has a Volkswagen-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 200hp engine designed by Opel.
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. 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, still it doesn't help us solve our dilemma, does it? Furthermore, if we'd like to consider vehicle mass in this context too, which we definitely should, Audi A3 offers a marginal difference of 7% more metal.
ReliabilityI don't like generalizing things when it comes to reliability, although it does seem that Opel does have a slight advantage, all the models observed together. These are the results of an independent reasearch, while our visitors describe reliability of Audi, as well as Opel, with the same average rating of 4.2 out of 5. Some independent research have also placed A3 as average reliability-wise, and Astra is more or less at the same level.We should definitely mention that owners of cars with the same powertrain as Audi A3 rank it on average as 2.5, while the one under the competitor's bonnet gets 4.0 out of 5.
Performance & Fuel economyAudi is a bit more agile, reaching 100km/h in 0.8 seconds less than its competitor. In addition to that it accelerates all the way to 236 kilometers per hour, 1km/h more than the other car. When it comes to fuel economy things look pretty much the same for both cars, averaging around 5.9 liters of fuel per 100 kilometers (48 mpg), in combined cycle.
Verdict
Opel 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. 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. 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.
