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 3-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 6-cylinder, 24-valves 250hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 240hp engine designed by Opel.
SafetyA starting point here would be to take a look at the results from European New Car Assessment Programme (Euro NCAP) tests which were performed on both of the cars, with the Opel being a slightly better choice apparently. 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, but it doesn't do much to help us decide between the two. Furthermore, when it comes to weight, a factor that most people underestimate, Audi A3 offers a considerable difference of 16% more metal.
ReliabilityManufacturers have been building their reliability reputation for decades now and, generally speaking, it appears that Opel does have a slight advantage, all the models observed together. That's the official data, while our visitors describe reliability of Audi, as well as Opel, with the same average rating of 4.2 out of 5. Independent research findings rank 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 4.3, while the one under the competitor's bonnet gets 5.0 out of 5.
Performance & Fuel economyOpel is a bit more agile, reaching 100km/h in 0.1 seconds less than its competitor. Still, it lacks the power to win the top speed competition, topping at 244 kilometers per hour, 6km/h less than the other car. When it comes to fuel economy the winner has to be Astra, averaging around 9.2 liters of fuel per 100 kilometers (31 mpg), in combined cycle. We can't ignore that 15% difference compared to Audi A3.
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 this case though, it seems that both cars show similar levels of passenger protection all together, so that won't break a tie. But one thing that actually could is the performance, with Opel offering somewhat better performance, just enough to call it quicker. 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 Opel. 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.
