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 diesel engine choice they offer. The first one has a Volkswagen-engineered powertrain under the hood, a 4-cylinder, 8-valves 100hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 101hp 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? On the other hand, when it comes to weight, a factor that most people underestimate, Astra offers a considerable difference of 10% more metal.
ReliabilityI don't like generalizing things when it comes to reliability, although it does seem that Opel does have a slight advantage, at least on all of the models level. These are the official statistics, while our visitors describe reliability of Audi, as well as Opel, with the same average rating of 4.2 out of 5. The same official information place A3 as average reliability-wise, and Astra is more or less at the same level.Above it all, drivers of cars with the same engine as Audi A3 rank it on average as 4.4, while the one under the competitor's bonnet gets 4.2 out of 5.
Performance & Fuel economyAudi is undoubtly more agile, reaching 100km/h in 1.5 seconds less than its competitor. In addition to that it accelerates all the way to 188 kilometers per hour, 5km/h more than the other car. When it comes to fuel economy the winner has to be Audi A3, averaging around 5 liters of fuel per 100 kilometers (57 mpg), in combined cycle. We can't ignore that 18% difference compared to Astra.
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, Astra offers significantly better overall protection, taking the lead here. 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! It's not difficult to say then that if I'd need to make a choice, it would definitely be 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. Also, you could use the oportunity to find out which car, everything taken into account, would be the perfect choice for you in the eyes of the virtual adviser™, among thousands of similar, yet so different vehicles.
