Virtual Adviser's™ opinion
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 wagon 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 Volkswagen-engineered powertrain under the hood, a 4-cylinder, 16-valves 115hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 105hp 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. Still, apart from the official crash test results there are other things we need to be aware of. 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. Furthermore, when it comes to weight, a factor that most people underestimate, Audi A3 offers a marginal difference of 4% more metal.
ReliabilityReliability is not the best thing to consider on the make level, but it is worth mentioning that Opel does have a slight advantage, when all the models are taken into account. 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. Some independent research have also placed A3 as average reliability-wise, and Astra is more or less at the same level.That apart, owners of different cars powered by the same engine as Audi A3 rank it on average as 4.4, while the one under the competitor's bonnet gets 3.8 out of 5.
Performance & Fuel economyAudi is undoubtly more agile, reaching 100km/h in 1.6 seconds less than its competitor. In addition to that it accelerates all the way to 196 kilometers per hour, 11km/h more than the other car. When it comes to fuel economy things look pretty much the same for both cars, averaging around 6.7 liters of fuel per 100 kilometers (42 mpg), in combined cycle.
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, Astra offers slightly better overall protection and takes the lead. 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. 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. In case you have two minutes to spare I invite you to define your needs, desires and budget and see which car would be chosen by the virtual adviser™, among thousands of similar, yet so different vehicles.
